Accompanying drawing explanation
Fig. 1 is simple HTML dom tree.
Fig. 2 is typical collaborative browse process once.
Embodiment:
Introduce specific embodiments of the invention below.
The instant collaborative browse method of a kind of webpage based on DOM and XMPP of the present invention is implemented as follows:
Obtaining of 1 collaborative browse information
A1. nodal information obtains
DOM is the API (application programming interfaces) for HTML and XML document.DOM has described the node tree of a stratification, allows developer to add, remove and revise certain part of the page.And can obtain the access to node.As shown in figure mono-.
When user clicks a certain position on webpage, can be on this node trigger (onclick) event of click, and along dom tree always upwards on path each node trigger successively, until bubbling is to document (Document) node.When triggering onclick event under we stipulate particular case, to pile stack mode by the node storage triggering successively.Because the visible node on the page is all the child node of <body> node, can generate thus the unique path to Event triggered node by <body>.
A2. text node interior location acquisition of information
For the text node on the page (TEXT_NODE that <p><aGreatT.Grea T.GT etc. includes), need to find out the particular location that user clicks in text.The method document.createRangeFromPoint () that can be provided by 2 grades of DOM that obtains of position realizes.
A scope (range) is founded in the position that the method is clicked the mouse user.After obtaining this range, change respectively its front and back side-play amount and check in range whether can comprise effective word.If so, return to range with respect to the initial offset of text node, as the positional information of text node inside.
A3. non-text node interior location acquisition of information
For the non-text node on the page (<img><inputGreat T.GreaT.GT etc.), need to determine that user click event is with respect to the offset information of this element, the event attribute that can be provided by DOM: event X skew (event.offsetX) and event Y skew (event.offsetY) obtain.
A4. markup information obtains
When user marks on webpage, in the page, insert mark layer.According to different situations, mark layer position obtained by one of above two kinds of methods, or directly obtain mark layer with respect to the side-play amount of full page.
The realization of 2 instant messagings
B1. the structure of message transfer
The content of message is that the <message> node by defining in XMPP agreement transmits.Except <body> node is transferring text, can in <message> node, add more child node to reach the functions such as positional information of transmitting collaborative browse.Can insertion position information node, transmit collaborative browse positional information.For JavaScript object transfer, JavaScript object can be converted to json object, a character string is transmitted.
B2. the parsing of message transfer is with compatible
Adopting the process contrary with message constructing, is text message by the information analysis in <body> node, by the information analysis in positional information, is routing information.
Owing to adopting XMPP communications protocol, can directly use existing XMPP account (no matter it belongs to is for which service provider) to login, can fast the social circle of oneself be dissolved into native system.
For the instant messaging network that adopts XMPP agreement, when resolving the XML file of XMPP transmission, only can resolve the part of this network support.If by this project and common user communications such as GTalk, other child nodes in <message> node except <body> node can be ignored automatically, and message deteriorates to a common text message.Need not change system can realize the compatibility with each main flow instant communicating system.
The parsing of 3 collaborative browse information
C1. node location information is resolved
After user receives collaborative browse information, first according to the routing information of node, from <body> node, the page, find rapidly the node identical with the other side, utilize skew (offset) property calculation of each node layer to go out this node with respect to the side-play amount of the page.
C2. intra-node positional information is resolved
According to the difference of node type, computing node internal blas amount.
For non-text node, directly resolve X skew (offset) and Y skew (offset) attribute.
For the inside of calculating text node during with respect to the position of father node, need to be according to side-play amount before and after the text node obtaining in text node, in relevant position, insert a blank <span> node, attribute by <span> node obtains it for the position of father node, then delete <span>, recover the original structure of text node.
C3. markup information is resolved
While resolving the mark layer information that the other side sends, insert mark layer in the page, resolve according to above method the position of mark layer.
The part that the present invention does not elaborate belongs to techniques well known.
