Checking a checkbox didn't work on the second try

I have a form, and when a user uploads a training document it will check the checkbox

$('#training_code_'+trainingCode).attr('checked','checked');

If the user deletes the training it will run this : 

$('#training_code_'+trainingCode).removeAttr('checked');

HTML: 

<input type="checkbox" value="1" name="training_code_1" id="training_code_1" 
<? if(mysql_num_rows($result_waperd)>0) echo"checked"; ?> disabled="disabled"/>

I tried to:

  1. upload a file and it's checked.
  2. delete the file and it's unchecked.
  3. upload a file again and it still unchecked.

Does anyone know why that happens?

For DOM properties like checked, disabled and readonly, the proper way to do this (as of JQuery 1.6) is to use prop.

$('#someid').prop('disabled', true);

so try (to check):

$('#training_code_'+trainingCode).prop('checked',true);

uncheck:

$('#training_code_'+trainingCode).prop('checked',false);
