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!");}});
