Specific implementation mode

The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure Completely it is communicated to those skilled in the art.

Referring to Fig.1, the method for showing a kind of webpage of load in a browser according to an embodiment of the invention is implemented The step flow chart of example 1, can specifically include following steps：

Step 101, the webpage that browse request downloads to is parsed, obtains the DOM tree structure data of the webpage Information；

In the concrete realization, user can send out the load request request of loading webpage of webpage.The load request of webpage can With refer to user send out load some webpage instruction.For example, user can load a net by clicking certain linking request Page, or carry out one webpage of request of loading etc. in address field input network address.When certain is linked when the user clicks, it is equivalent to receive The load request that user loads webpage is arrived；Equally, when inputting certain network address in address field and click confirming button or press carriage return When key, also correspond to have received the load request that user loads webpage.

Wherein, the content of load request may include the mark of the webpage of user's request of loading and/or the feature of webpage.Net Page mark can represent the information for the webpage that one uniquely determines, such as uniform resource identifier (Uniform Resource Identifier, URI), uniform resource identifier can specifically include uniform resource locator (Uniform again Resource Locator, URL) or uniform resource name (Uniform Resource Name, URN) etc..

After the load request for receiving webpage in a browser, browser can pass through DNS (Domain Name System, domain name analysis system) parse domain name (Domain Name) mapped IP (Internet searched in webpage URL Protocol, the agreement interconnected between network) address.After obtaining IP address success, browser can be to the IP address institute Server ask connection.After the server where being successfully connected the IP address, browser end can believe request header Breath passes through the clothes where HTTP (Hypertext transfer protocol, hypertext transfer protocol) agreement to this IP address Business device initiates the request of webpage load.The server receives after the request etc. pending, finally returns and rings to browser end It answers.

At this point, under http protocol, browser can receive HTML (Hypertext Markup from server Language, hypertext markup language) type document.Browser can parse html document, generate the object of tree, That is DOM (Document Object Model, document dbject model) tree construction data information.

Step 102, the web page element text of specified type in the DOM tree structure data information is obtained；The webpage member Plain text includes source address；

In practical applications, the DOM tree structure data information may include one or more nodal informations, each webpage Element can be a node on DOM tree structure data information, and these objects can represent the webpages such as word, picture member Element.

Node in DOM tree structure data information possesses hierarchical relationship each other.Father (parent), son may be used (child) and the terms such as born of the same parents (sibling) are for describing these relationships.Wherein, father node possesses child node.Son section at the same level Point is referred to as (brothers or sisters) born of the same parents.In node tree, top node is referred to as root (root).Each node has father's section Point, in addition to root (it does not have father node).One node can possess any number of son, and compatriot is the section for possessing identical father node Point.

In a kind of alternative embodiment of the present invention, step 102 may include following sub-step：

Sub-step S11 matches the address information of the webpage in preset web page element list of types；

In the concrete realization, the address information of webpage can be URL etc., can be stored in the web page element list of types There are the correspondence of the address information of webpage and the type information of web page element, instruction browser can be to specified type webpage member Plain content storage server downloads the web page element of specified type in the webpage.

Sub-step S12, when successful match, the class for the web page element that extraction needs are downloaded from web page element list of types Type information；

When successful match, it may indicate that the web page element of specified type in the webpage has been stored in advance in specified type In web page element content storage server, then the type information for knowing web page element is needed.

In a kind of optional example of the embodiment of the present invention, the web page element of the specified type may include it is following at least It is a kind of：

Text message, image information, audio data, video data.

Wherein, may include the image of the multiple formats such as GIF, JPG, PNG for image information；It, can for audio data May include MPEG, AVI, RM, RMVB for video data with the audio of the multiple formats such as including MP3, WMA, WAV, MIDI The video data of equal multiple formats.

For example, the example of the web page element list of types is as shown in the table：

The address information of webpage	The type information of web page element
		http://photo.aaa.com.cn/	Image information
http://news.bbb.com.cn/	Text information, image information, video data
		http://2014.ccc.com.cn/	Image information, video data
http://book.ddd.com.cn/	Text information

Wherein, network address " http:The corresponding webpages of //photo.aaa.com.cn/ " can be that some specially provides image Webpage channel, including image information it is more；Network address " http:The corresponding webpages of //news.bbb.com.cn/ " can be certain It is a it is special provide news webpage channel, including text information, image information, video data all compare it is more；Network address “http:The corresponding webpages of // 2014.ccc.com.cn/ " can be some special net for providing world cup race information in 2014 Page channel, including image information, video data all compare it is more；Network address " http://book.ddd.com.cn/ " is corresponding Webpage can be some special webpage channel that provide books and periodicals information, including text information it is relatively more.

The type for the web page element that different web pages are included is different, but user makes such to the request of the webpage The number of request of the web page element of type is larger, and web page element (such as image information) volume of itself is also larger, in order to mitigate The download pressure of web page server, therefore the webpage can be prestored in specified type web page element content storage server The web page element of middle specified type.

Certainly, the web page element of above-mentioned judgement specified type is intended only as example, can be with when implementing the embodiment of the present invention The web page element of other specified types is set according to actual conditions, and the embodiment of the present invention does not limit this.In addition, in addition to upper It states outside the web page element of specified type, those skilled in the art can also use the webpage of other specified types according to actual needs Element, the embodiment of the present invention also do not limit this.

Sub-step S13, when the type information is matched with the nodal information, from the nodal information described in extraction The web page element text of specified type.

In practical applications, can wish to operate (such as specified type) to search in node tree by several method Web page element：

For example, can by using getElementById () method and getElementsByTagName () method into Row is searched.

In another example can be belonged to by using parentNode, firstChild and lastChild of a node element Property.

Wherein, getElementById () and getElementsByTagName () both methods can search entire Any web page element in html document.And both methods usually ignores the structure of document, if it searches all in document< p>Element, getElementsByTagName () method can find all of which, no matter<p>Element is in document Which level.Meanwhile getElementById () method can also return to correct element, no matter it is hidden in file structure In where.Both methods can provide any required HTML element, no matter they are the location of in a document.

In addition, getElementById () can return to web page element by specified ID.

It should be noted that the web page element found can be web page element text, such as source address rather than net Page element content, i.e. web page element data itself.

For example, in network address " http:The type for the web page element specified in the corresponding webpages of //photo.aaa.com.cn/ " Information is image information, if finding the source place of web page element in the node in the DOM tree structure data information of the webpage Location is " http://photo.aaa.com.cn/img/bdlogo.gif ", the source address may indicate that corresponding web page element Format be GIF, belong to image information, then can extract the source address.

Step 103, according to the source address of specified type web page element, to the corresponding specified type web page element of browser Storage server makes requests on the download for carrying out the specified type web page element content；

In the concrete realization, specified type web page element storage server can be cache server (cache Server), largely it is deployed in the network computer room in multiple specified regions, such as each urban district, forms cache server cluster, be The browser in specified region is serviced (such as the download for the web page element content for providing specified type).

In recent years, Internet (internet) applications increase at an unprecedented rate, and large-scale terminal user is to band Width is put forward higher requirements, if lacking careful management, this bandwidth requirement is meaned for internet service provider Expensive expense, in addition, will cause largely not from the Internet request of data of terminal (such as browser) each time Appreciable delay.

Cache server plays the part of an intermediary role, an effective caching between terminal and entire Internet Server is reduced as much as possible directly in response to the request of terminal through the Internet number of requests transmitted and Web browser Limited caching function is different, and cache server is come using a large amount of memory spaces while servicing a large amount of user.Thus, caching clothes Business device can be that popular Web site quickly provides newest data, and cache server can also accelerate by local user The access speed of other Web sites accessed, for those demand datas, the user beyond browser rs cache limitation especially has With.

By disposing cache server, the original data for accessing Internet resources can be converted to access cache service Device has effectively saved massive band width.

Browser can start to show the html document of webpage, and obtain the source address of wherein embedded web page element, If the source address of specified type web page element, then progress can be made requests on to specified type web page element storage server The download of specified type web page element content；If not the source address of specified type web page element, then can be to web page server Make requests on the download for downloading the web page element content.

In a kind of alternative embodiment of the present invention, the web page element list of types can information depending on the user's operation It generates.

Then apply the embodiment of the present invention, specified type web page element storage server that can acquire in advance by various modes The operation information of user, wherein may include in the local operation behavioural information of user and the online operation behavior information of user It is at least one.

The user behavior information can be acquired by the client software for installing on a user device, wherein the use Family equipment may include all kinds of intelligent terminals such as computer, laptop, mobile phone, PDA, tablet computer.

The local operation behavioural information of several acquisition users presented below, and/or, the online operation behavior information of user Example：

Example 1 acquires user's online operation behavior information interior for a period of time by browser, includes the network address and phase of access The webpage etc. collected in the access times answered, browser collection folder；

Such as acquiring the online operation behavior information in user 15 days by browser is：

Access network address	Access times
		www.aaa.com	31
www.bbb.com	2
		www.ccc.com	7
www.ddd.com	4

Example 2 acquires the local operation behavioural information of user by installing security software on a user device, such as by adopting Local behavioural information in collection user 15 days is：Some TV play and its frequency are opened, some game and its frequency etc. are opened.

By the analysis of the operation information to user, the behavioural habits of user can be obtained, as user's custom access is certain Website, or have larger demand to the website for search/access which type, then specified type web page element content storage server can To download the web page element of specified type in the website in advance.For example, downloading the website middle finger (when such as daily 6) in preset time Determine the web page element of type or receives the web page element for the specified type that the website is actively submitted.Meanwhile specified type webpage Element storage server can update web page element list of types, and at the appointed time or browser free time (as not into Row web page access or file download) when, web page element list of types is pushed in browser.

It should be noted that the behavioural habits due to user have the timeliness of part so that user accesses Relatively centralized, Such as during Football World Championship, user largely accesses the relevant report of world cup race, but in the part timeliness failure Afterwards, user accesses and can reduce therewith, such as after Football World Championship, and user's report relevant to this world cup race is often It can largely reduce, therefore, web page element list of types may exist local variation's property with the variation that user behavior is accustomed to.When So, there is relative stability since user's own interests are formed by behavioural habits, such as user likes football race, it can be frequent The relevant report of the league football matches races such as England Premier League, Division A League Matches of Spanish Football is accessed, therefore there may also be stablize relatively for web page element list of types Property.

In a kind of alternative embodiment of the present invention, the specified type web page element content storage server can pass through Following manner returns to web page element content：

Sub-step S21, when the corresponding web page element content of the source address is stored in the specified type web page element When storage server, judge whether the web page element content is expired；If so, sub-step S22 is executed, if it is not, then executing son Step S23；

Sub-step S22 downloads web page element content according to the source address from the corresponding web page server of the webpage；

Sub-step S23 extracts the corresponding web page element content of the source address；

Sub-step S24 returns to the web page element content to browser.

In the concrete realization, it if specified type web page element storage server finds the source address, may indicate that The corresponding web page element of the source address is downloaded and is stored in advance.

Browser includes web page element in the request header information of the webpage load request sent to web page server Expired time.

The expired time is encapsulated in specified type web page element storage server and sends download specified type net by browser In the request of page element, it is sent to specified type web page element storage server.

Specified type web page element storage server can be by the expired time and the download time for downloading the web page element It is compared, if download time is less than expired time, may indicate that the web page element content is effective, extract the web page element Server is returned to after content；If download time is more than expired time, it may indicate that the web page element content expiration fails, need The corresponding web page element content of the source address is downloaded to web page server, returned again to browser.

The present invention another alternative embodiment in, the specified type web page element storage server can by with Under type returns to web page element content：

Sub-step S31, when the corresponding web page element content of the source address is not stored in the specified type webpage member When plain storage server, web page element content is downloaded from the corresponding web page server of the webpage according to the source address；

Sub-step S32 returns to the web page element content to browser.

It in the concrete realization, can be with table if specified type web page element storage server does not find the source address The corresponding web page element of the bright source address does not download storage, then needs to download the source address to web page server corresponding Web page element content, returns again to browser.

Step 104, when rendering load webpage, the specified class downloaded from specified type web page element storage server is used Type web page element is rendered, and is loaded in webpage.

When browser gets the web page element in webpage, Rendering operations can be carried out in the html document of browser, To show the web page element in interface.
