Question

I have the following function in my jQuery code:

function checkUNSelectBox(item){ 
    $('#DELETE option').each(function(){ <!--alert(item);-->
        if ($(this).val() !=item) { 
            $(this).attr("disabled", "disabled");
            return false;   
        }
    });
}

However, only the first item in the list is being disabled instead of all the rest that are not equals to “item”. Why is this so?

Answer 1

don’t need to return false in function you just remove it.

 function checkUNSelectBox(item){ 
 {
   $('#DELETE option').each(function(){

  if($(this).val() != item)
  {
    $(this).attr('disabled','disabled');
  }   

});
