Question

I send to a php page a request and the output is like that

   <?php
   echo "<div id=\"someid\">
         innerHTML
        </div>"
   ?>

I try to catch the element but it doesnt work

     var a=document.getElementById('someid');
     alert(a.innerHTML);//alert nothing

How do I fix it with pure javascript?

Answer 1

If you are getting the content of a PHP page with AJAX (not includeing it), you have to append it to the DOM somewhere.

Are you appending it to the DOM in your code?

If you are using include, require, etc. then that is not AJAX.

You would have to wait until the page is loaded, so the code would go something like this:

window.onload = function() {
    var elem = document.getElementById('foo');
    alert(elem.innerHTML);
}
