i need to make a clear function !
i have DIV FULL OF INPUTS , DDL's , CheckBoxes , etc ...
i need to set all its values to null after every operation !
i've tried this :

C#

me.claerControls = function (id) {

       $("#" + id + "[type='text']").val('');
       $("#" + id + "[type='radio']").prop('checked', false);

   };

Why doing so? Why null? What's the problem?
What have you tried so far?

Guess he's trying to reset values.

Then it's hardly null.

I know, maybe he just can't explain himself properly.
But, based on his code, i think he's trying to reset values.

I understand. The value depends on control. It could be "", false, and so on...
What's the problem? Just do it. You actually can add your reset functions to all controls, depending on their types, and then call it in some loop or recursive method. You can even add such function to control prototypes.

That's why i've asked him about div's id. The solution, given that "UserEdit" is div's id (because this changes the meaning of selectors he's using), is quite simple.

Is your div's ID "UserEdit", Right?

Ok, the problem here is the meaning of your selector.

JavaScript

me.claerControls = function (id) {
    $("#" + id + "[type='text']").val('');
    $("#" + id + "[type='radio']").prop('checked', false);
};

What you have written here is the same as:

JavaScript

$("#UserEdit[type='text']")

and this mean "give me a node whose id is #UserEdit AND type=text"

I think you can do what you want this way:

JavaScript

me.clearControls = function (id) {
     var $container = $("#" + id); //Select the div first, so this will "shorten" the path to elements inside it
     $(":text", $container).val(''); //Give the container div as a context
     $(":radio", $container).prop('checked', false).change(); //maybe you'll need to trigger a "change" event, after changing prop's value, this could be done like in this line.
     $(":checkbox", $container).prop('checked', false).trigger("change"); // I prefer to use trigger
     $('select', $container).prop('selectedIndex', 0);
};
