.attr("disabled", "disabled") problem

Question

i have this function where basically add and remove the disabled attribute form a input field:

$(bla).click(function(){        
  if (something) {
     console.log($target.prev("input")) // gives out the right object
     $target.toggleClass("open").prev("input").attr("disabled", "disabled");
  }else{
     $target.toggleClass("open").prev("input").removeAttr("disabled"); //this works
  }
})

the removeAttr works fine but when i need to add the disabled again it does just nothing. My console.log is triggering (and giving me back the right input field) so I'm sure my that my if statement works. But if i inspect the DOM with firebug the disabled attribute does not appear.

can someone help me?

PS: please don't focus on the function or the if statement itself, works fine its just that attr that does not work for disabled...

edit: its an input type="hidden" is it possible that disabled does not work on hidden fields?

Try this updated code :

$(bla).click(function(){        
  if (something) {
     console.log($target.prev("input")) // gives out the right object
     $target.toggleClass("open").prev("input").attr("disabled", "true");
  }else{
     $target.toggleClass("open").prev("input").removeAttr("disabled"); //this works
  }
})

DEMO: http://jsbin.com/uneti3/3

your code is wrong, it should be something like this:

$(bla).click(function() {
    $target.toggleClass('open');   
     var disable = ( $target.hasClass('open') ) ? true: false;
     $target.prev("input").attr("disabled", disable);
  });

you are using the toggleClass function in wrong way

Try

$(bla).click(function(){        
  if (something) {
     console.log("A:"+$target.prev("input")) // gives out the right object
     $target.toggleClass("open").prev("input").attr("disabled", "disabled");
  }else{
     console.log("A:"+$target.prev("input")) // any thing from there for a single click?
     $target.toggleClass("open").prev("input").removeAttr("disabled"); //this works
  }
});

Thank you all for your contribution! I found the problem:

ITS A FIREBUG BUG !!!

My code works. I have asked the PHP Dev to change the input types hidden in to input type text. The disabled feature works. But the firebug console does not update this status!

Here is the proof:

you can test out this firebug bug by your self here http://jsbin.com/uneti3/3#. Thx to aSeptik for the example page.
