问题:

How can I access the content of an iframe with jQuery? I tried doing this, but it wouldn\'t work:

iframe content: <div id=\"myContent\"></div>

jQuery: $(\"#myiframe\").find(\"#myContent\")

How can I access myContent?

Similar to jquery/javascript: accessing contents of an iframe but the accepted answer is not what I was looking for.

You have to use the contents() method:

$(\"#myiframe\").contents().find(\"#myContent\")

<html>
<head>
<title></title>
<script type=\"text/javascript\" src=\"http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js\"></script>
<script type=\"text/javascript\">

$(function() {

    //here you have the control over the body of the iframe document
    var iBody = $(\"#iView\").contents().find(\"body\");

    //here you have the control over any element (#myContent)
    var myContent = iBody.find(\"#myContent\");

});

</script>
</head>
<body>
  <iframe src=\"mifile.html\" id=\"iView\" style=\"width:200px;height:70px;border:dotted 1px red\" frameborder=\"0\"></iframe>
</body>
</html>

If iframe\'s source is an external domain, browsers will hide the iframe contents (Same Origin Policy). A workaround is saving the external contents in a file, for example (in PHP):

<?php
    $contents = file_get_contents($external_url);
    $res = file_put_contents($filename, $contents);
?>

then, get the new file content (string) and parse it to html, for example (in jquery):

$.get(file_url, function(string){
    var html = $.parseHTML(string);
    var contents = $(html).contents();
},\'html\');
