我想获得iframe的.text(),但它不起作用. iframe位于同一个域中.一次点击我将页面加载到框架,第二次我想在警报中显示内容,但我得到空警报.
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready( function() {
// load simple paage to the frame
$("#load").click( function(){
$("<iframe id='theframe' width='400' // single line
height='400' src='http://localhost/dummy.html'/>").appendTo('body');
} );
// display the content - but I get empty alert
$('#content').click( function() {
var content;
content = $("#theframe").text();
alert(content);
});
});
</script>
</head>
<body>
<a id='load' href="#">load</a>
<a id='content' href="#">check content</a>
</body>
</html>
解决方法
取自：
Selecting an element in iFrame jQuery
var iframe = $('iframe'); // or some other selector to get the iframe
$('[tokenid=' + token + ']',iframe.contents()).addClass('border');`
