asp.net mvc 与jquery应用总结

1.DropDownList的Name和ViewData相同时SelectList 的selected 失效

1  SelectList ZDZListItem  =   new  ListItem < HGZP.Model.Cjb_list_fxz > ().GetListItem(ZDZList,  " s_mch " ,  " s_mch " ,
2  orderInfo.CurrentZDZ);

3 
4  <%  var aa  =  ((SelectList)ViewData[ " ZDZ111 " ]).SelectedValue.ToString();
5  if ( ! string .IsNullOrEmpty(aa)){  %>
6  <% :Html.DropDownListFor(OrderInfo  =>  OrderInfo.ZDZ, ViewData[ " ZDZ111 " ]  as  SelectList,  new  { id  =   " ddlZDZ " , 

  Style  =   " width:70px " , @class  =   " focus " , disabled  =   " true "  }) %><%  } else { %>
7  <% :Html.DropDownListFor(OrderInfo  =>  OrderInfo.ZDZ, ViewData[ " ZDZ111 " ]  as  SelectList,  new  { id  =   " ddlZDZ " , 

  Style  =   " width:70px " , @class  =   " focus "  }) %>

8  <% } %><%= Html.DropDownList( " ddlSysid " , (SelectList)ViewData[ " ZDZ111 " ]) %>

2.使用jquery.form.js上传文件

服务器上传文件目录名称不能与controller名称相同，如果相同URL导航会出现错误

ajaxSubmit方法中dataType使用默认值不能用json

服务器端返回时要跳转到其他view

 

strJson  =   " {suc:1,msg:'保存成功！',orderId:' "   +  orderInfo.OrderId  +   " ',orderDetailId:' "   +  orderInfo.OrderDetailId  +   @" ',chargeId:' "   +  orderInfo.ChargeId  +   " ',giftDetailId:' "   +  orderInfo.GiftDetailId  +   " ',PaperBoxNum:' "   +  
orderInfo.PaperBoxNum  +   " ',SubscibeNum:' "   +  orderInfo.SubscibeNum  +   " '} " ;

ViewData[ " strJson " ]  =  strJson;
return  View( " ~/Areas/OrderInfoManage/Views/FileUploadSuccess.aspx " , ViewData[ " strJson " ]);

<% @ Page Language = " C# "  Inherits = " System.Web.Mvc.ViewPage<dynamic> "   %>
<%
String json  =  ViewData[ " strJson " ].ToString();
Response.Write(json);
%>

 

如果附加其他属性（form以外的）可以如下处理

orderValue  =  JSON.stringify({
            orderId: $( " #txtOrderId " ).val(),
            orderDetailId: $( " #txtOrderDetailId " ).val(),
            paperBoxNumOld: $( " #txtPaperBoxNumOld " ).val(),
            subscibeNumOld: $( " #txtSubscibeNumOld " ).val(),
            chargeId: $( " #txtChargeId " ).val(),
            giftDetailId: $( " #txtGiftDetailId " ).val(),
            giftKCId: $( " #txtGiftKCId " ).val(),
            paperName: $( " #ddlNewsPaper option:selected " ).text(),
            giftName: $( " #ddlGift option:selected " ).text(),
            isCheck: $( " #txtIsCheck " ).val()
        });
        eval( " orderValue = ' "   +  JSON.stringify(JSON.parse(orderValue))  +   " '; " );

$( " #orderManageForm " ).ajaxSubmit({
                    url:  " OrderManage/OrderAllAdd/ " ,
                     // contentType: "multipart/form-data",
                     // dataType: 'json',
                    data: {
                        strJson: escape(orderValue)
                    },
                    
                    clearForm:  false ,
                    resetForm:  false ,
                    success: function (data) {
                         try  {
                            var json  =  eval( " ( "   +  data  +   " ) " );
                            alert(HTMLDeCode(json.msg));
                             if  (json.suc  ==   1 ) {
                                $( " #txtOrderId " ).val(json.orderId);
                                $( " #txtOrderDetailId " ).val(json.orderDetailId);
                                $( " #txtChargeId " ).val(json.chargeId);
                                $( " #txtGiftDetailId " ).val(json.giftDetailId);
                                $( " #txtPaperBoxNumOld " ).val(json.PaperBoxNum);
                                $( " #txtSubscibeNumOld " ).val(json.SubscibeNum);
                                orderValue  =  JSON.stringify({
                                    orderId: $( " #txtOrderId " ).val(),
                                    isCheck: $( " #txtIsCheck " ).val()
                                });
                                eval( " orderValue = ' "   +  JSON.stringify(JSON.parse(orderValue))  +   " '; " );


                                jQuery( " #orderGrid " ).jqGrid( " setGridParam " , {
                                    postData: { strJson: orderValue }
                                });
                                jQuery( " #chargeGrid " ).jqGrid( " setGridParam " , {
                                    postData: { strJson: orderValue }
                                });
                                $( " #orderGrid " ).trigger( " reloadGrid " );
                                $( " #chargeGrid " ).trigger( " reloadGrid " );
                                saveFlag  =   " OrderUpdate " ;
                                $( " #orderAllSaveBtn " ).attr( " disabled " ,  " true " )
                            }
                            $( " #txtZDDate " ).focus().trigger( " focusin " );
                        }  catch  (e) {
                            alert(e);
                             return ;
                        }
JsonModel jsonObj  =   new  JsonModel(System.Web.HttpUtility.UrlDecode(Request[ " strJson " ]));
