在帧内调用特定的id [英] Calling a specific id inside a frame

问题描述

我在mainpage.html中有一个iframe标记，iframe调用back.html ..

I have a iframe tag in mainpage.html, that iframe calls back.html..

有没有办法只调用back.html中的特定ID用于在iframe中显示..

is there any way to call only the specific ids in back.html for display in iframe..

详细信息：
我在back.html中有25x25表。最初，iframe显示所有625个细胞最小化。每个单元格都有唯一的ID。我可以调用特定的单元格来显示iframe内部的原始尺寸。

Detail: I have 25x25 table in back.html. initially iframe shows all 625 cells minimised. each cell has a unique id. can i call a specific cell only to display(original size) inside iframe.

还是有其他方法可以解决它...请注明

or is there any other way to go around it.. please specify

推荐答案

试用此代码：

var iframe    = document.getElementById('your-iframe-ID'), 
                /* or other kind of reference to the iframe DOM node */

    iframeDoc = ((!!iframe['contentDocument']) 
              ? iframe.contentDocument 
              : iframe.contentWindow.document),

    cell      = iframeDoc.getElementById('your-cell-ID');
                /* this is a reference to cell inside the iframe */

当然我假设 mainpage.html 和 back.html 位于同一个域中（对于同源政策）

Of course I assume that mainpage.html and back.html are in the same domain (for the same-origin policy)
