Add attribute to dynamicaly created table

Helo,

I'm working with external software which is generating reports. I'm getting table, then it is printed to website in div. I don't have access to this table before it is generated, so i can't set any attribute before website is rendered.

So I need to add attribute to this table as last step of rendering process, it doesn't matter is it ID or Class.

Structure is like:

 <div class="data" id="Checklist">
     <p>Some text</p>

     <!-- There is this table -->
     <table style="...">...</table>

     <p></p> 
 </div>

I'm using IE v11.

I tried something like this (nothing happens):

  document.getElementById("Checklist").childNodes[0].className = "TestClassName";

Also (it gives mi error: Object doesn't support property or method 'setAttribute' )

 document.getElementById('news').childNodes[0].setAttribute( 'class', new_class );

Any other ideas?

Solution

  • If you use ChildNodes it will return all the white space with nodelist so use children so that it will return only child elements

    <div class="data" id="Checklist">
     <p>Some text</p>

     <!-- There is this table -->
     <table style="...">...</table>

     <p></p> 
 </div>

    Change Your js to 

    document.getElementById("Checklist").children[0].className="TestClassName";
document.getElementById('news').children[0].setAttribute( 'class', new_class );

    it will work
