推荐答案
（ ＃accordion）。accordion（{
collapsible： true ，
有效： false ，
}）;
< / script >
< / body >
< / html >
("#accordion").accordion({ collapsible: true, active: false, }); </script> </body> </html>
假设您的iFrame的ID是targetFrame并且你要调用的函数是targetFunction（）：
Assume your iFrame''s id is "targetFrame" and the function you want to call istargetFunction():
document.getElementById('targetFrame').contentWindow.targetFunction();
注意： 您还可以使用 window.frames 而不是 document.getElementById 。
但是 - 如果创建了IFRAME，则不能使用window.frames ammatically，只有它在HTML页面源中声明
干杯，

NOTE: You can also access the frame using window.frames instead of document.getElementById.
BUT - You can''t use "window.frames" if your IFRAME was created programmatically, only if it is declared in the HTML page source
