[RESOLVED] PHP and Javascript problem

@BIOSTALLApr 13.2010 — #Do you have any code you could provide? It might help us understand what exactly is going on and what you are trying to achieve.

Cheers

@mavalos88authorApr 13.2010 — #Sure, it looks something like this (condensed version of what I do):

This function creates my html element. For purposes of this example, assume newRowValue =1 so the element will be called Quantity1

[CODE]
 <head>
 
 function addRow(tableId) {
 var table = document.getElementById(tableId);
 newRowValue= document.getElementById('activeProducts').value;
 newRowValue=parseInt(newRowValue)+1;
 document.getElementById('activeProducts').value=newRowValue.toString();
 var row = table.insertRow(newRowValue);
 var i=1;
 var cell1 = row.insertCell(0);
 var optn;
 var element1 = document.createElement("select");
 element1.name= "Quantity"+newRowValue;
 element1.id= "Quantity"+newRowValue;
 for (i=1;i<100; i++){ 
 optn = document.createElement("option");
 optn.text = i;
 optn.value = i;
 element1.options.add(optn);
 } 
 cell1.appendChild(element1);
 }
 </head>
 [/CODE]

With php I add a new row with my javascript function (assume the table products exists and has no rows):

[CODE]
 <html>
 <table id='products'>
 </table> 

 <?php
 echo"
 <script>
 addRow('products');
 </script>
 ";
 ?>
 ...
 [/CODE]

after I add the row I try to populate the newly created element:

[CODE]
 ....
 
 <?php
 echo"
 <script>
 document.getElementbyId('Quantity1').value= 'some value';
 </script>
 ";
 ?>
 </html>
 
 [/CODE]

The above line throws the error: document.getElementById("Quantity1") is null, which obviously means that the element doesn't exist.

The element does indeed exist though, it shows perfectly on my web page and it even is submitted if I try to do so.

Source code of the page doesn't show the newly created row and element though.

I transcribed this from the top of my head so there might be syntax errors (not logical errors though) so if you notice any, that's not the problem, my code runs fine.

Tried to be as clear as possible, hope you guys can help me out.

Thanks!

@mavalos88authorApr 13.2010 — #Found the error, nothing to do with this, an error elsewhere.

Thanks though!
