jquery实现ajax提交表单的两种方法

方法一：

分别获取所需数据元素,DOM结构外层不用包form标签（适用于数据量少，数据元素分散于整个页面）

$.ajax({
　　type: 'POST',
   url:'',
   data: {
        residence:[$('#region_1').val(),$('#region_2').val(),$('#region_3').val()],
        address:$('#address').val()
   },
   dataType: 'json',
   success: function(data){
   },
   error:function(err){
   }
   });

方法二：

需要包裹form标签（适用于数据量大，元素集中）

function AddHandlingFeeToRefund()
        {var AjaxURL= "../OrderManagement/AjaxModifyOrderService.aspx";       
            alert($('#formAddHandlingFee').serialize());
                $.ajax({
                    type: "POST",
                    dataType: "html",
                    url: AjaxURL + '?Action=' + 'SubmitHandlingFee' + '&OrderNumber=' + $.trim($("#<%=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);
                     }
                });
        }

html代码：

<form id="formAddHandlingFee" name="formAddHandlingFee" 
enctype="multipart/form-data" onsubmit="AddHandlingFeeToRefund()">
<table id="AddHandlingFee" class="Wfill">
<tr><td><asp:Literal ID="UI_Amount" runat="server" Text="处理费用" meta:resourcekey="HandlingFeeAmount" />
</td><td><input type="text" id="txtHandlingFeeAmount" name="txtHandlingFeeAmount"  
class="{required:true,number:true}" maxlength="12" />
</td></tr><tr><td>
<asp:Literal ID="UI_HandlingFeeType" runat="server" Text="费用类型" meta:resourcekey="HandlingFeeHandlingFeeType" />
</td><td><crmweb:HtmlSelectControl ID="HandlingFeeType" EnumTypeName="DX.OMS.Model.Common.HandlingFeeType,DX.OMS.Model.Common" EmptyValue="" EmptyText="Select" runat="server" class="text {required:true}"/>
</td></tr><tr><td><asp:Literal ID="UI_Notes" runat="server" Text="备注" meta:resourcekey="HandlingFeeNotes" /></td><td><textarea id="txtNotes" name="txtNotes" class="text {required:true}" 
cols="22" rows="2" maxlength="100"></textarea></td></tr><tr><td></td><td><input id="Submit1" type="submit" value="添加处理费"  />
<asp:Button ID="Button1"  runat="server" Text="添加处理费" OnClientClick="javascript:AddHandlingFeeToRefund()" /></td></tr></table>
</form>
