Using jQuery I am trying to access div id=\"element\".


    
        <iframe>
            <div id=\"element         
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-5408099190056760"
     data-ad-slot="7305827575"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>        </div>
      </div>
      
      <div class="fly-panel detail-box" id="flyReply">
        <fieldset class="layui-elem-field layui-field-title" style="text-align: center;">
          <legend>8条回答</legend>        </fieldset>

        <ul class="jieda" id="jieda">
                    <li data-id="111" class="jieda-daan">
            <a name="item-1111111111"></a>
            <div class="detail-about detail-about-reply">
                         <a class="fly-avatar" href="">
                <img src="https://www.e-learn.cn/qa/data/avatar/000/00/00/small_000000073.jpg" alt=" 予麋鹿 ">
              </a>
              <div class="fly-detail-user">
                <a href="" class="fly-link">
                  <cite> 予麋鹿</cite>

                <span>2020-11-28 08:44</span>
              </div>

            </div>
            <div class="detail-body jieda-body photos">

<p>Hey I got something that seems to be doing what you want a do. It involves some dirty copying but works. You can find the working code here</p>

<p>So here is the main html file : </p>

<pre><code><!DOCTYPE html>
<html>
<head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

    <script type="text/javascript">
        $(document).ready(function(){
            Iframe = $('#frame1');

            Iframe.on('load', function(){
                IframeInner = Iframe.contents().find('iframe');

                IframeInnerClone = IframeInner.clone();

                IframeInnerClone.insertAfter($('#insertIframeAfter')).css({display:'none'});

                IframeInnerClone.on('load', function(){
                    IframeContents = IframeInner.contents();

                    YourNestedEl = IframeContents.find('div');

                    $('<div>Yeepi! I can even insert stuff!</div>').insertAfter(YourNestedEl)
                });
            });
        });
    </script>
</head>
<body>
    <div id="insertIframeAfter">Hello!!!!</div>
    <iframe id="frame1" src="Test_Iframe.html">

As you can see, once the first Iframe is loaded, I get the second one and clone it. I then reinsert it in the dom, so I can get access to the onload event. Once this one is loaded, I retrieve the content from non-cloned one (must have loaded as well, since they use the same src). You can then do wathever you want with the content.

Here is the Test_Iframe.html file :






    Test_Iframe

and the Test_Iframe2.html file :






    I am the second nested iframe
