本文介绍了一种在CRM页面中加载IFRAME并绑定事件的方法，通过监测IFRAME的加载状态，实现对其内部onmousedown事件的覆盖，以展示警告消息或执行特定操作。

1 var IFRAME_Test;
2 var IFRAME_Test_Disable_Message = " IFRAME Disabled

" ;
3
4 function OnCrmPageLoad() {
5    // Reference the IFRAME
6   IFRAME_Test = document.all.IFRAME_Test;
7    // Bind to its ready state event (wait until the iframe is fully loaded)
8   IFRAME_Test.attachEvent( " onreadystatechange " , OnTestIframeReady );
9 }
10
11 function OnTestIframeReady() {
12    if ( IFRAME_Test.readyState != " complete " )
13        return ;
14    // Override the onmousedown event
15   IFRAME_Test.contentWindow.document.onmousedown = OnTestIframeMouseDown;
16 }
17
18 function OnTestIframeMouseDown() {
19   alert( IFRAME_Test_Disable_Message );
20    /* or use */
21    // the window is put beyond the user's desktop and is immediately closed
22    var stubWin = window.open(‘about:blank’,’’,’  toolbars = 0 ,width = 100 ,height = 100 ,top = 10000 ,left = 10000 ’);
23   stubWin.close();
24    return false ;
25 }
26
27 // Entry point
28 OnCrmPageLoad();
