iFrame onload JavaScript 事件 [英] iFrame onload JavaScript event

问题描述

我有一个 iFrame，我想在加载后发送一个 JavaScript 命令.我当前的代码如下所示:

I have an iFrame, where I want to send a JavaScript command after loading. My current code looks like this:

<iframe src="http://www.test.tld/" onload="__doPostBack('ctl00$ctl00$bLogout','')">

但是使用此代码，命令不会被执行.我必须改变什么才能使它工作?只需要支持 Chrome 和 Firefox.

But with this code the command isn't executed. What must I change to make it work? Only Chrome and Firefox have to be supported.

推荐答案

使用JavaScript的iFrame的.onload函数:

Use the iFrame's .onload function of JavaScript:

<iframe id="my_iframe" src="http://www.test.tld/">
    <script type="text/javascript">
        document.getElementById('my_iframe').onload = function() {
            __doPostBack('ctl00$ctl00$bLogout','');
        }
    </script>
    <!--OTHER STUFF-->
</iframe>
