Eliminate any untagged text on the page

Is there a way to remove dynamic text that appears on an HTML page without any surrounding tags, using jQuery?

The text in question looks like this:

<div id="Container2" class="tab default-tab" style="display: block; margin-top: -15px; overflow: auto; width: 990px; height: 400px;">   
<!-- start -->

Search Setup 1 FIA - need to remove this {the text appearing is dynamic}

<style>other contents go here 

Answer №1

If your HTML looks like:

<div id="Container2" class="tab default-tab">   
<!-- start -->

Search Setup 1 FIA - need to remove this {the text appearing is dynamic}

<span>other content here</span>
 </div>

And you only want to delete the text content within the div, leaving the span untouched, you can achieve it with this code snippet:

$(function(){
  $('#Container2').contents()
                  .filter(function(){
                       return this.nodeType == 3; // text nodes
                  })
                  .remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="Container2" class="tab default-tab">   
<!-- start -->

Search Setup 1 FIA - need to remove this {the text appearing is dynamic}

<span>other contant here</span>
 </div>

Answer №2

This function locates plain text within a div element and deletes it

$("#Container2").contents().each(function(index, elem) {
  if ($.trim(elem.nodeValue) != '' && elem.nodeType == 3){
    alert($.trim(elem.nodeValue))
    $(elem).remove();
    }
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="Container2" class="tab default-tab" style="display: block; margin-top: -15px; overflow: auto; width: 990px; height: 400px;">   
<!-- start -->
Search Setup 1 FIA - need to remove this {the text appearing is dynamic}
<span>other contents go here</span>
</div>
