推断仅仅有是数字字符串才发送

$("#duration").on('input',function(e){
	    var value=$("#duration").val();
	    //alert($.isNumeric(value));

	    if($.isNumeric(value)){
	    	$("#mistakeText").html("");
	    	$.get("/springmvc/input/change",{number:value},function(data){
		    	$("#chinaText").html(data+"分钟");
		    });
	    }else{
	    	$("#mistakeText").html("请输入数字!");
	    }

	});
