Change text of current selected option on a DropDownCheckList element

Hi.

I have a web application which uses DropDownCheckList element: http://dropdown-check-list.googlecode.com/svn/trunk/doc/dropdownchecklist.html

When user mark a checkbox, a prompt message appears asking for a numer.
How can I concatenate this number just after the text beside the just marked checkbox?

This is a snippet of my code:
		$("#proves").dropdownchecklist({
			onItemClick: function(checkbox, selector){
			var justChecked = checkbox.prop("checked");
				if (justChecked){
					num_autoritz_p = prompt("Número d'autorització:","");
					if (num_autoritz_p.length>0){
						codi_nou = checkbox.val();
						a_proves[codi_nou] = num_autoritz_p;
					}
					else
						checkbox.prop("checked",false);
				}
				else {
					codi_nou = checkbox.val();
					a_proves[codi_nou] = null;
					delete(a_proves[codi_nou]);
				}
	
			} // Fi function onItemClick
		}); // Fi definició dropdownchecklist

Open in new window


Thank you.

Hi,

this should work:
$("#proves").dropdownchecklist({
			onItemClick: function(checkbox, selector){
			var justChecked = checkbox.prop("checked");
				if (justChecked){
					num_autoritz_p = prompt("Número d'autorització:","");
					if (num_autoritz_p.length>0){
						codi_nou = checkbox.val();
						a_proves[codi_nou] = num_autoritz_p;
                        oldText = $('#proves option[value="'+codi_nou+'"]').text();
                        newText =  oldText + "-" + num_autoritz_p;
                        $('#proves option[value="'+codi_nou+'"]').text(newText);
                        $('label[for="' +checkbox.prop("id") + '"]').text(newText);
					}
					else
						checkbox.prop("checked",false);
				}
				else {
					codi_nou = checkbox.val();
					a_proves[codi_nou] = null;
					delete(a_proves[codi_nou]);
				}
	
			} // Fi function onItemClick
		}); // Fi definició dropdownchecklist

Thank you. Yes, it works, however I have two problems:

1. Is it possible also to remove the num_autoritz_p when user un-mark the checkbox?

2. If user marks the checkbox with the most large text, then the added number goes out of the control: scrollbars appear and number appeared on the page background instead of on the control's background.

Thanks.
