Re: JavaScript DOM with setAttribute when creating dynamic ids

In the code below, the id isn't found is because you need to append the new element to the DOM.
Below is working model of what I think you want:

Hi:


Now that's weird, OK, so now when I try to increment the count get the same issue not found,

 var itemCount = 0;
  
    var newElement = document.createElement('div');

    document.body.appendChild(newElement);  // <-- Here, new element is appended to the BODY tag. 

             // Once part of the DOM, document.getElementById(id) should find it. 

    newElement.className="dialog-form";   
   newElement.setAttribute("id", 'updateCC' + itemCount);   
   itemCount++;  //Increment the count 
or
itemCount += 1;


Thanking You In Advance;

    newElement.setAttribute("style","display:none;");

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.
