This time I will bring you jQuery Cross-domain operation of the DOM method in the iframe, jQuery cross-domain operation of the DOM method in the iframe. What are the precautions? The following is a practical case. Get up and take a look.

frame is still quite popular and is used in many places to implement special situations. For example, traditional

upload, select under ie6, proxy, cross-domain, etc. Today, I will briefly describe the related operations across iframes, mainly using jQuery to operate the DOM structure.

<iframe src="a.php" id="aa"></iframe> 
<iframe src="b.php" id="bb"></iframe> 
<input type="button" id="read-aa" value="读取iframe #aa"> 
<input type="button" id="write-aa" value="写入iframe #aa">

$(&#39;#read-aa&#39;).click(function() 
{ 
    var v=$(&#39;#aa&#39;).contents().find(&#39;body&#39;).html(); 
    alert(v); 
}); 
$(&#39;#write-aa&#39;).click(function() 
{ 
    $(&#39;#aa&#39;).contents().find(&#39;p&#39;).append(&#39;<hr>这是index.php操作aa.php写入的内容&#39;); 
});

The main method is contents(), which reads iframe.

2. iframe cross-parent frame operation iframe

<!DOCTYPE html> 
<meta charset="utf-8"> 
<title>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb</title> 
<script src="public/jQuery.js"></script> 
<script> 
$(function() 
{ 
    $(&#39;#read-parent-aa&#39;).click(function() 
    { 
        var v=$(&#39;body&#39;,parent.document).find(&#39;#aa&#39;).contents().find(&#39;body&#39;).html(); 
        alert(v); 
    }); 
    $(&#39;#write-parent-aa&#39;).click(function() 
    { 
        $(&#39;body&#39;,parent.document).find(&#39;#aa&#39;).contents().find(&#39;p&#39;).append(&#39;<hr>这是bb.php操作aa.php写入的内容&#39;); 
    }); 
}); 
</script> 
<p>

This is the content in iframe #bb

</p> 
<input type="button" id="read-parent-aa" value="跨父读取iframe #aa"> 
<input type="button" id="write-parent-aa" value="跨父写入iframe #aa">

HTML: code

<!DOCTYPE html>
<meta charset="utf-8">
<title>jQuery操作iframe</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<iframe src="a.php" id="aa"></iframe>
<iframe src="b.php" id="bb"></iframe>
<input type="button" id="read-aa" value="读取iframe #aa">
<input type="button" id="write-aa" value="写入iframe #aa">
<script> 
$(function()
{
 $(&#39;#read-aa&#39;).click(function()
 {
  var v=$(&#39;#aa&#39;).contents().find(&#39;body&#39;).html();
  alert(v);
 });
 $(&#39;#write-aa&#39;).click(function()
 {
  $(&#39;#aa&#39;).contents().find(&#39;p&#39;).append(&#39;<hr>这是index.php操作aa.php写入的内容&#39;);
 });
});
