Question

I have div tag with css class name. div class name is same in for other div tags. I want findout a text inside the div tag with css class name and replace with next text

  <div class="ms-listdescription">            
 Share a document with the team by adding it to this document library.
  </div>

with new text

 <div class="ms-listdescription">             
      Share a document with the team by adding it to this document library 
           <br/> new text.
    </div>

Update: This is very simple just find text “Share a document with the team by adding it to this document library” in if it is matches text then only append new text with existing text.

Answer 1

You can check that it contains text by using :contains().

$(".ms-listdescription:contains('Share a document with the team by adding it to this document library')")
    .html(
        $(".ms-listdescription").html() + $("<br>new text")
    );
