您可以使用隐藏的div并将其中的noscript标记内容附加为html

<强> 实施例

var noscript_text = $("noscript").text();     //get noscript tag content
$('#noscript').append($(noscript_text));      //append to another div to get the image src
var get_img_src = $('#anaImg').attr('src');   // get the img src
var new_img_src = "nothing";                  // type your new img src here
var replace_img_src = noscript_text.replace(get_img_src,new_img_src); // replace old img src with new one
$("noscript").text(replace_img_src);          // change the content of no script tag with new src
alert($("noscript").text());                  // alert the new noscript tag content

#noscript{
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<noscript>
<p><img src="http://xxxxxxxx.xxxxxxxxxxx.com/analytics/conv_tracking.php?idsite=1545" style="border:0;" alt="" id="anaImg"/></p>
</noscript>

<div id="noscript"></div>

注意：请注意#noscript这是div和的ID noscript这适用于noscript代码

使用javascript检索<noscript>标签数据
