问题描述
这是我的代码：
< div id =main-content>
< script>
document.title = document.getElementById（main-content-iframe）。contentDocument.title;
< / script>
< / div>
这不起作用，我做错了什么？
< / p> div id =main-content>
< script src =https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js>< / script>
< script>
$（iframe）.on（'load'，function（）{
document.title = document.getElementById（main-content-iframe）。contentDocument.title;
}）;
< / script>
This is my code:
<div id="main-content">
<script>
document.title = document.getElementById("main-content-iframe").contentDocument.title;
</script>
<iframe name="cstage" src="home.html" width="100%" height="100%" id="main-content-iframe" frameborder="0" onload="document.title=parent.frames['cframe'].document.title;">If you're seeing this message, it means IFrames are not supported; Please enable IFrames or upgrade to a compatible browser that supports IFrames.</iframe>
</div>
It's not working, what am I doing wrong?
解决方案
You need to check that the iframe is loaded.
<div id="main-content">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<iframe name="cstage" src="home.html" width="100%" height="100%" id="main-content-iframe" frameborder="0" onload="document.title=parent.frames['cframe'].document.title;">If you're seeing this message, it means IFrames are not supported; Please enable IFrames or upgrade to a compatible browser that supports IFrames.</iframe>
<script>
$( "iframe" ).on('load',function() {
document.title = document.getElementById("main-content-iframe").contentDocument.title;
});
</script>
