Mark passes to page C, that is, passes to file service end.
File destination mark can be interacted acquisition by client and file service end, and file destination mark is for unique
Identify a file.
In one embodiment of the application, page A (for example, js script in page A) can by the domain name of page A and
File destination mark, which is added in the header information of file server requests, is sent to file service end, and file service end passes through detection
The header information of file server requests obtains the domain name and file destination mark of page A.
In another embodiment of the application, page A can be directly by the domain name of page A and file destination mark splicing
Some parameter into the URL of page C in hash field, passes to file service end, and file service end parses from URL and obtains
The domain name and file destination of page A identifies.
That is, page A can transmit the domain name of page A to page C by the src attribute of iframe and file destination identifies,
For example, utilize iframe src=" ... server domain name/C.html? client domain name=XXX&& file identification=XXX " >
</iframe>transmit the domain name and file destination mark of page A.
File service end is identified according to file destination obtains the corresponding file destination content of file destination mark, and passes through
Iframe label comes in file destination content packet, i.e., the content of displaying target file in page C.
S120, the client obtain the size of the file destination.
The size of the available file destination of script D.js, in one embodiment of the application, file service end is by mesh
The src attribute that size of the file at file service end is assigned to the iframe comprising page B is marked, in this way, page B can obtain mesh
File is marked in the size at file service end, in turn, script D.js can also obtain the size of file destination.
S130, the client are calculated according to the size of the file destination and the display parameters of the client
The height of iframe in the client.
Client is calculated according to the size of the file destination received and the display parameters of client in script D.js
Actual height after the height of iframe, the i.e. page C insertion page A when displaying target file.Script D.js calculates target
File can pass to page A after the display height of page A by page B, due to page B and page A belong to it is same
Domain, the DOM element in the accessible page A of page B, so that the display height of file destination is passed to page A.
The display parameters of display where the display parameters of client refer to the client, such as the resolution of the display
Rate.File destination is calculated under current display environment according to the resolution ratio of display and the size of file destination in client
The display height of (resolution ratio of display where client).
The cross-domain height adaptive method of iframe provided in this embodiment, nested not same area in host's page (page A)
Interface page (page C) will realize the content (file destination) that the display interface page is included in host's page；In order to realize
Cross-domain height adaptive is embedded in the first page (that is, page B) with host's page same area in interface page.Page C can be incited somebody to action
The size of file destination passes to page B, then, by the script D.js in page B according to the size of file destination and A pairs of the page
The display parameters answered are calculated display height of the file destination under the display environment of client where page A, and this are shown
Show that height passes to page A by page B.Finally, the iframe height comprising page C is set file destination by page A
Display height (that is, actual height after page C insertion page A), the final iframe height for realizing page A always with page C
Actual height it is consistent, improve the accuracy of the cross-domain height adaptive of iframe.
Fig. 3 is referred to, the flow chart of the cross-domain height adaptive method of the embodiment of the present application another kind iframe is shown, it should
It is further comprising the steps of on the basis of method embodiment shown in Fig. 2:
S210, client receive display height of the file destination at the file service end of first page transmitting.
After executing S110, S210 is executed.
Page C load file destination after, the available file destination of script D.js in page C display height (that is,
The height of page C).For complete displaying target file, moreover, different browsers determine these three height when parsing the page
Justice may not also be identical, and therefore, the display height of page C can take the body object of the file destination of html format
Maximum value in scrollheight, offsetHeight and clientHeight.
Then, the display height of page C is assigned to the src attribute of the iframe comprising page B by script D.js, then by the page
The height of page C is passed to page A (the transfer mode phase of the size of the transfer mode and file destination of the height of page C by B
Together).
Whether the display parameters of S220, the display parameters and client that detect the file service end are identical；If identical,
Then execute S230；If it is not the same, then executing S120；
File service end can share its display parameters, and client is after the display parameters for obtaining file service end, judgement
Whether the display parameters of the two are identical.Display parameters, that is, display resolution ratio.
S230 sets file destination content in the display height at file service end for the height of iframe in client.
If the display parameters at file service end are identical as the display parameters of client, file destination is at file service end
Display height (that is, display height of page C) it is identical as display height (that is, display height of page A) in client, because
This, can directly set the iframe height of client to the display height of page C.
The cross-domain height adaptive method of iframe provided in this embodiment obtains file destination in the height at file service end
Degree, if the display parameters at file service end (page C) are identical as the display parameters of client (page A), in such cases, mesh
The display height that file is marked in page C is identical as the display height in page A, therefore, can be directly by the iframe's of page A
Height is set as the display height value of page C, does not need page A according to the size of file destination and recalculates file destination in visitor
The display height at family end, adaptive process is simple, and can guarantee the iframe height of page A always with the height phase of page C
Deng.
Fig. 4 is referred to, the flow chart of the cross-domain height adaptive method of another iframe of the embodiment of the present application is shown, it should
Method is applied to file service end.The interface page at file service end, this document server-side and client are nested in client
Belong to different domains, that is, cross-domain access, in order to realize the cross-domain height adaptive of iframe, insertion and client at file service end
The first page for holding same area transmits the information at file service end by first page to client.
As shown in figure 4, this method may comprise steps of:
S310, file service end receive the file read request that client is sent.It include client in this document read requests
The domain name and file destination at end identify.
S320 identifies acquisition file destination according to file destination and identifies corresponding file destination in the storage at file service end
Address.
After file service end obtains file destination mark, the file destination is obtained from database and identifies corresponding target text
The actual storage address of part.
S330, file service end obtain the size of file destination content and file destination according to the storage address.
Then, the target text in the corresponding memory space of storage address of the file destination obtained is read at file service end
Part.Meanwhile obtaining the size of the file destination.
The file destination of acquisition is loaded into the interface page being embedded in client by S340, file service end.
The file destination of acquisition is included by file service end (that is, page C) by iframe label, is realized target
File is loaded into page C.
In one embodiment of the application, file destination is stored in a manner of word at file service end, that is, file
Format is doc or docx, and therefore, file service end needs that word formatted file is first converted into hypertext markup language (hyper
Textmarkup language, html) format file, then the file destination of html format is loaded into page C.
The size of file destination is passed to first page by S350, file service end.
Client calculates the iframe of client according to the size of the file destination received and the display parameters of client
Highly.
The size of file destination is assigned to the src attribute of the iframe comprising page B by page C, and page B is again by file destination
Size pass to script D.js.Script D.js is according to the size of file destination and the current display parameters of page A (that is, page A
The resolution ratio of place display), file destination is calculated in the display height of page A, and display height is passed into page
Height thus is arranged in iframe height comprising page C by face A, page A.
In another embodiment of the application, script D.js can obtain file destination in the display height at file service end
(that is, original height of page C), and page A is passed to by page B.And the display parameters at file service end can also be total to
Enjoy and give page A, in this way, page A may determine that file service end display parameters and client display parameters it is whether identical, such as
Fruit is identical, and the original height value of page C can be directly assigned to the height of the iframe of page A by page A, to make page A's
Iframe height is identical as the height of page C.
In another embodiment of the application, multiple vertical scroll bars may be shown by being further fully solved host's page
The problem of, when file destination is converted after html file, the style sheet of default is added in the html file of generation, by html text
Each paragraph of part all uses paragraph tag (that is,<P>label) to wrap up, and all paragraph tags are wrapped up with<div>box,
The DOM element in the div of innermost layer is only allowed to show vertical scroll bar, the vertical scrolling of the DOM element of outer layer covers file destination
Item does not allow it to occur, i.e. setting overflow:hidden；Alternatively, scrolling=" no ", can guarantee vertically to roll in this way
The uniqueness of dynamic item, is not in two or more vertical scroll bars.
The cross-domain height adaptive method of iframe provided in this embodiment, nested not same area in host's page (page A)
Interface page (page C) will realize the content (file destination) that the display interface page is included in host's page；In order to realize
Cross-domain height adaptive is embedded in the first page (that is, page B) with host's page same area in interface page.Page C can be incited somebody to action
The size of file destination passes to page B, then, by the script D.js in page B according to the size of file destination and A pairs of the page
The display parameters answered are calculated display height of the file destination under the display environment of page A, and display height are passed through
Page B passes to page A, finally, page A sets the iframe height comprising page C to the display height of file destination
(that is, actual height after page C insertion page A), the final iframe height for realizing page A always with the practical height of page C
Degree is consistent, improves the accuracy of the cross-domain height adaptive of iframe.
