Dynamically set frame src using Javascript
提问by testndtv
I have a HTML element
我有一个 HTML 元素
<frame src="#" title="Content Frame" name="content" id="content" />
I want to set it's "src" dynamically using Javascript on page load. How can I do that ?
我想在页面加载时使用 Javascript 动态设置它的“src”。我怎样才能做到这一点 ？
I am trying something like;
我正在尝试类似的东西；
document.getElementById('content2').contentWindow.location = 'xyz_frame.html';
But for some reason it is not working..Again it is a element and not
但由于某种原因它不起作用..再次它是一个元素而不是
A Rough code;
一个粗略的代码；
<html>
<head>
<script language="javascript">
function LoadPage(){
document.getElementById('content2').src = 'ipad_lrd_frame.html';
}
</script>
</head>
<body onload="LoadPage()">
<frame id="content2"></frame>
</body>
</html>

This should work;
这应该有效；
document.getElementById('content2').src = "url";
(Also you have mismatched IDs for the frame and getElementByIdcall)
（此外，您的框架和getElementById呼叫的ID 不匹配）
For a FRAME, you need a FRAMESETwhich precludes the use of a BODY, so;
对于 a FRAME，您需要 aFRAMESET排除使用 a BODY，所以；
<frameset rows="50%,*" onload="LoadPage();">
<frame id="content2"></frame>
.....
Update:
更新：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<script type="text/javascript">
function LoadPage(){
document.getElementById('content1').src = "http://www.google.com";
document.getElementById('content2').src = "http://www.bing.com";
}
</script>
<title></title>
</head>
<frameset rows="50%,*" onload="LoadPage();">
<frame src="#" id="content1">
<frame src="#" id="content2">
</frameset>
</html>

I would think fetching frames by name would be more suitable:
我认为按名称获取帧会更合适：
document.getElementsByName('content2')[0].src = 'ipad_lrd_frame.html';
Tested it successfully. Ensure your page uses a frameset doctypeand you do notinclude bodytags (use framesettags instead). Also note your script type should be text/javascript, rather than language "javascript".
测试成功。确保您的页面使用框架集doctype并且不包含body标签（改用frameset标签）。另请注意，您的脚本类型应该是text/javascript，而不是语言“javascript”。
