编辑：我有成功刷新页面的方法，但它只创建了2次调用我的控制器方法，这是不必要的，页面在第一次调用时不会更新。任何人都可以帮助在第一次通话时更新页面吗？
现在我是Ajax调用的新手，所以我不知道如何在执行我的控制器方法后刷新我的视图或Webgrid。 而且我也无法在Ajax中查找是否调用了success方法。 我在每个Ajax调用中都面临这个问题，为什么在控制器方法返回时不会更新View。
我所做的是，有DropDownlist，并且在选择值并提交时会显示webgrid。
Webgrid有复选框，选中复选框并点击提交将一些数据通过AJax传递给控制器方法。数据在DataBase 中更新，但它不会反映在视图中直到我刷新它。
如何自动刷新视图？
任何帮助都将不胜感激。
我有View如下：
$("#save_btn").on("click", function () {
var ischecked = 0;`enter code here`
$('#tblFormentry').find("input:checkbox").each(function () {
if (this.checked) {
var chck = $(this).attr("value");
var hidden = $(this).closest('td').find(':hidden');
villcode = villcode + "," + hidden.val();
singlestring = singlestring + "," + chck;
}
});
if ((singlestring != null && singlestring != "") && (villcode != null && villcode != "")) {
alert(singlestring);
if (confirm("Are you sure?") == true) {
$.ajax({
url: "@Url.Action("getmultipleids", "Admin")",
contentType: "application/json; charset=utf-8",
data: { 'ids': singlestring, 'villcode': villcode },
type: "GET",
cache: false,
success: function (result) {
$("body").html(result);
singlestring = "";
villcode = "";
},
failure: function (errMsg) {
alert(errMsg);
}
});
}
else {
singlestring = "";
}
}
else {
alert("Please select at least 1 Entry!");
}
});

以下是在jQuery AJax调用的帮助下调用的控制器方法。
public ActionResult getmultipleids(string ids, string villcode)
{
//need verificatN date, verified, verification user = admin, formno, villagecode
int i;
string[] formno = ids.Split(',');
string[] village_code = villcode.Split(',');
DataTable dt = new System.Data.DataTable("Entries");
DateTime today = DateTime.Today;
DataRow dr;
DataColumn dc;
dt.Columns.AddRange(new DataColumn[5] {
new DataColumn("verification_date", typeof(DateTime)),
new DataColumn("verified", typeof(Char)),
new DataColumn("verification_user", typeof(string)),
new DataColumn("formno", typeof(Int64)),
new DataColumn("village_code", typeof(string))
});
for (i = 1; i < formno.Count(); i++)
{
dr = dt.NewRow();
dr["verification_date"] = today;
dr["verified"] = 'Y';
dr["verification_user"] = "admin";
dr["formno"] = Int64.Parse(formno[i]);
dr["village_code"] = village_code[i];
dt.Rows.Add(dr);
}
try
{
actionResult = objfamilyBAL.Update_Entry(dt);
TempData["Message"] = actionResult.Message;
ViewBag.Agencylist = (SelectList)Session["ddlist"];
if (ShowResultMessage(actionResult, true, false))
{
int op = 1;
int agncyid = (int)Session["agency_id"];
String WorkArea = Session["wrkArea"].ToString();
actionResult = objfamilyBAL.Fetch_verify_griddata(op, agncyid, WorkArea);
if (actionResult.IsResult)
{
List<CommonTableEntity> family_entitylist = (List<CommonTableEntity>)actionResult.ObjResult;
ViewBag.formentry = family_entitylist;
}
}
if (actionResult.IsErrorMessage)
{
TempData["ErrorMessage"] = actionResult.ErrMessage;
}
}
catch (Exception ex)
{
ModelState.AddModelError("", ex.Message);
}
return View("VerifyEntry");
}
很抱歉很长的帖子。
