原生ajax表单交互

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);
 }
 });
 }

以下就是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>
