Is there a way to add a custom http header into the request done by an </code> when changing the source (src) using javascript?</p> <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>4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_000000046.jpg" alt=" 既然无缘 "> </a> <div class="fly-detail-user"> <a href="" class="fly-link"> <cite> 既然无缘</cite> </a> <span>(楼主)</span> </div> <div class="detail-hits"> <span>2020-12-02 11:45</span> </div> </div> <div class="detail-body jieda-body photos"> <p> <p>The following code works. It is a modification of the code provided by Matthew Graves, modified to use the <code>srcdoc</code> attribute to solve the problem of CSS and JavaScript references not been ran. Unfortunately, it is only working in Chrome.</p> <pre><code> $.ajax({ type: "GET", url: "https://app.icontact.com/icp/a/", contentType: "application/json", beforeSend: function(xhr, settings){ xhr.setRequestHeader("some_custom_header", "foo");}, success: function(data){ $("#output_iframe_id").attr('srcdoc',data) } }); </code></pre> <p><strong>Edit</strong>: Finally, I have resolved the issue of the scripts blocks cross-browser, by reassigning them to the iframe on document.ready function:</p> <pre><code>$(document).ready(function () { var doc = $(document); if (frames.length > 0) { doc = frames[0].document; $(doc).find('script').each(function () { var script = document.createElement("script"); if ($(this).attr("type") != null) script.type = $(this).attr("type"); if ($(this).attr("src") != null) script.src = $(this).attr("src"); script.text = $(this).html(); $(doc).find('head')[0].appendChild(script); $(this).remove(); }); } }); </code></pre> </p> <div class="appendcontent"> </div> </div> <div class="jieda-reply"> <span class="jieda-zan button_agree" type="zan" data-id='717981'> <i class="iconfont icon-zan"></i> <em>0</em> </span> <span type="reply" class="showpinglun" data-id="717981"> <i class="iconfont icon-svgmoban53"></i> 讨论(0) </span> <div class="jieda-admin"> </div> <div class="noreplaytext bb"> <center><div> <a href="https://www.e-learn.cn/qa/q-194566.html"> 查看其它4个回答 </a> </div></center> </div> </div> <div class="comments-mod " style="display: none;
