1.DropDownList的Name和ViewData相同时SelectList的selected失效1 SelectList ZDZListItem new ListItem
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" %>
<%
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"]));
