Can't disable button using Javascript

hi all,

I am trying to disable a button on my CC list depending on a certain field in the data table.

Here is the code

<?php $state = "{$row['in_marketplace']} " ; ?>
<script>
var x = "<?php echo $state ; ?>" ;
if (x == "yes") 
{
document.getElementById("marketplace").disabled = true; 
}
else  
{
document.getElementById("marketplace").disabled = false; 
 }
</script>

$state will be either yes or no, if its yes, i want to disable the button i have set with ID 'marketplace'

Anyone know why this is not working?

Thanks in advance

Allan

Thanks for the help, i have put your revised code into a function and calling it from the onload event as below, but i cant get it to work. any ideas?

<script>

function disableBtn() {

window.addEvent('domready', function(){
<?php $state = "{$row['in_marketplace']} " ; ?>
   var x = "<?php echo $state ; ?>" ;
   if (x == "yes")
   {   
      document.getElementById("marketplace").disabled = true;
   }
   else 
   {
      document.getElementById("marketplace").disabled = false;
   }
});
}
window.onload=disableBtn;
</script>

Hi allanbeth,

Your code structure isn't quite the same as Sloan's, you have the window.addEvent() inside the function so it won't run until the function is called.

I have a more fundamental question. Why are you doing this with JavaScript. If it's running the the CC Body box can't you just set the disabled='disabled' with PHP?

Hi Bob,

Not sure i can answer the question🙂 Still Learning!!🙂

You are, of course 100% correct, i was making it more complicated than i needs to be.

I am now doing it using PHP. plus i am not disabling the button, but hiding it using the following

<?php if ($row['in_marketplace'] == "yes") echo 'style="display:none;"' ?>

I had to use the hide method as i am using the buttons as links for a modal window so the disabled method didn't work for me as the button is being treated like a link. (Think i have that correct.)

Thanks for all your help

Hi allanbeth,

Looks OK to me.
