cannot clear value numberbox with clear method

[Opan Mustopah]

hello again.

i got a little problem again.
why i can't clear value or text numberbox element with clear method?
here is my code, i'm sure nothing's wrong with code:

Code:

$('#nw').numberbox({
      onChange:function(newValue,oldValue){
        var nw_val = newValue;
        var gw_val = $('#gw').numberbox('getValue');
        if (nw_val != "" && gw_val != ""){
          if (!isNaN(gw_val) && !isNaN(nw_val)){
            if (parseFloat(nw_val) > parseFloat(gw_val)){
              $(this).numberbox('clear');
              $.messager.alert('Info',"NW must be lower than GW",'info');
            }
          }
        }
      }
    });

it should clear numberbox value and text. can you tell me maybe where is wrong in my code?

many thanks for the answer.

Please try to override the 'setValue' method for the numberbox component.

Code:

(function($){
	$.extend($.fn.numberbox.methods, {
		setValue: function(jq, value){
			return jq.each(function(){
				var target = this;
				var state = $.data(target, 'numberbox');
				var opts = state.options;
				value = opts.parser.call(target, value);
				var text = opts.formatter.call(target, value);
				opts.value = value;
				$(target).textbox('setText', text).textbox('setValue', value);
			})
		}
	});
})(jQuery);

thanks jarry for that code, it works now.
but why i must extend setValue method when this plugin is inherited from textbox?
