Datagrid row filter - remote filter should not called if no filtervalue changed

[Stefan B.]

We used the default row filter from type=text and the filter fetch remote data after the delay of 1000

Code:

remoteFilter: true,
filterDelay: 1000

But the filter also fetch remote data if the filter text not changed!
Exsample: Click on the filter textfield and then only navigate in the filtertext, or you select part of filtertext with keyboard arrows.

I have seen in the datagrid-filter.js file, that all key events used to call the doFilter() method!
This should only done if the filter value changed or enter is pressed!

Code:

				input.unbind('.filter').bind('keydown.filter', function(e){
					var t = $(this);
					if (this.timer){
						clearTimeout(this.timer);
					}
					if (e.keyCode == 13){
						_doFilter();
					} else {
						this.timer = setTimeout(function(){
							_doFilter();
						}, opts.filterDelay);
					}
				});

I think this shoud be done only when the filter value changed

You can override the $.fn.datagrid.defaults.defaultFilterOptions, or download the updated 'datagrid-filter.js' file from http://www.jeasyui.com/extension/datagrid_filter.php

Hello. Now I used the updated 'datagrid-filter.js'.
That works better.

But if no text is in the textbox, the doFilter() methode is every time called if i press any key. So if i go with tab-key from one to the next column filter the remote filter is also called
