Passing javascript variable to iframe src
Can someone help me if correcting this code. I couldnt figure out where i went wrong. The javascript variable is not replacing the src.
P.S. This should run as a Google Chrome extensions.
<html>
<head>
<script type="text/javascript">
function convert()
{
var url4="test"
document.getElementById("link").src=url4;
}
</script>
</head>
<body onload="convert()">
<i开发者_运维知识库frame src="wwwx" id="link" width="100%" height="300">
<p>Your browser does not support iframes.</p>
</iframe>
</body>
</html>
Because the JavaScript is being run before the <iframe> is in the DOM, it will never be able to access it.
Try moving your JS to just after the iframe but before the </body> tag:
<html>
<head></head>
<body>
<iframe src="wwwx" id="link" width="100%" height="300">
<p>Your browser does not support iframes.</p>
</iframe>
<script>
function convert() {
var url4 = "test";
document.getElementById("link").src=url4;
}
convert();
</script>
</body>
</html>
加载中,请稍侯......
