jquery的ajax提交form表单的两种方法小结(推荐)

function AddHandlingFeeToRefund()

    {
      var AjaxURL= "../OrderManagement/AjaxModifyOrderService.aspx";    
      alert($('#formAddHandlingFee').serialize());
        $.ajax({
          type: "POST",
          dataType: "html",
          url: AjaxURL + '"#<%=this.txtOrderNumber.ClientID %>").val()),
          data: $('#formAddHandlingFee').serialize(),
          success: function (result) {
            var strresult=result;
            alert(strresult);
            //加载最大可退金额
            $("#spanMaxAmount").html(strresult);
          },
          error: function(data) {
            alert("error:"+data.responseText);
           }

        });

    }

    //ajax提交form表单的方式
    $('#formAddHandlingFee').submit(function() {
      var AjaxURL= "../OrderManagement/AjaxModifyOrderService.aspx";    
      alert($('#formAddHandlingFee').serialize());
        $.ajax({
          type: "POST",
          dataType: "html",
          url: AjaxURL + '"#<%=this.txtOrderNumber.ClientID %>").val()),
          data: $('#formAddHandlingFee').serialize(),
          success: function (data) {
            var strresult=data;
            alert(strresult);
            //加载最大可退金额
            $("#spanMaxAmount").html(strresult);
          },
          error: function(data) {
            alert("error:"+data.responseText);
           }

        });
    }

  );
