The method in the controller

	@RequestMapping (value = "/feedback", method = requestmethod.post) public
	@ResponseBody
	String Feedback ( HttpServletRequest request, HttpServletResponse response, Feedbackmodel feedback) throws exception{
		//todo
		Return "Thank you very much for your valuable comments or suggestions to us";
	}

	var feedbackadviceform = "#feedbackAdviceForm";	

	$ (Feedbackadviceform). Submit (function () {
		if ($.trim ($ ("#advice", Feedbackadviceform). val ()) = = "") {
			alert ( "Please input your valuable comments or suggestions." ");
			$ ("#advice", Feedbackadviceform). focus ();
			return false;
		}
		$ (this). Ajaxsubmit ({
			success:function (msg) {
				alert (msg);
			},
			error:function (context, XHR) {
				alert (context.responsetext);});
	});
