Re: JavaScript DOM with setAttribute when creating dynamic ids

You will wonder whether to laugh or cry. Personally, I recommend you laugh.

All I did was take out the D in the line if(document.getElementById('updateCCD' + itemCount))

making it 'updateCC' and then it worked as you expected.

Hello:

I have a question, I have been working on this all day with setAttribute() method. The research and reading I have the done the
below code should work.  I ran into an issue which forces me to have to create unique ids for an element.

var itemCount =0;
var newElement = document.createElement('div');
  newElement.setAttribute("id", 'updateCC );   //This works fine when I do the following test

 if(document.getElementById('updateCC')){
      //do stuff
      alert("Found it updateCC" );    
     
    }
   
    else {
      alert("Not found updateCC" );
      }
Found

but when I do the following

  newElement.setAttribute("id", 'updateCC' + itemCount);

The previous test fails, I even tried

 if(document.getElementById('updateCCD' + itemCount)){
      //do stuff
      alert("Found it updateCC" + itemCount);    
     
    }
   
    else {
      alert("Not found updateCC" + itemCount);
      }

It will give me the count but it still fails saying Not found

My documents(books) and Google searches, it should work.
What am I missing here.


Thanking You in Advance, I work on this all day and it has put me at a stand still.
