我在视图中有下拉列表,并使用控制器中的值加载此下拉列表。在更改事件时,我需要将数据传递给控制器,之后下载列表会重新加载。但我希望在发布到控制器后保留所选值。我的jQuery如下:
$.ajax({
url: "/TimesheetModels/GetUsersForTimesheet",
type: "Get",
success: function (data) {
for (var i = 0; i < data.length; i++) {
opt = new Option(data[i].First_Name, data[i].EmpId);
$('#ddlUsers').append(opt); //Load drodown list while page load
}
}
});
$('#ddlUsers').change(function () {
alert($(this).val());
var empId = $(this).val();
startDate = $('#calendar').fullCalendar('getDate').startOf('week');
window.location.href = "/TimesheetModels/TimesheetApproval?selectDate=" + convertDate(startDate) + "&empId=" + empId; //Pass data to controller
alert(empId); // i get this alert before pass to controller
$('#ddlUsers').val(empId);
});
在控制器中我有这个功能,
public ActionResult TimesheetApproval(string SelectDate,string empId)
{
DateTime startDate;
if (!DateTime.TryParse(SelectDate, out startDate))
startDate = DateTime.Today.AddDays(-(int)DateTime.Today.DayOfWeek);
int EmpId;
if (empId != null)
EmpId = Convert.ToInt32(empId);
else
{
EmpId = Convert.ToInt32(Session["EmpId"].ToString());
}
string startDateCalendar = Convert.ToString(startDate.ToString("ddd MMM dd yyyy HH:mm:ss")) + " GMT+0530";
ViewData["startDateCalendar"] = startDateCalendar;
DateTime endDate = startDate.AddDays(6);
List<TimesheetMatrix> _timesheetList = _timesheetDetailViewModel.GetAllProjectTasks(startDate, endDate, EmpId);
return View(_timesheetList);
}
任何人都可以帮我解决这个问题吗?

您应该在更改下拉列表时执行ajax发布,如下所示: -
$('#ddlUsers').change(function () {
alert($(this).val());
var empId = $(this).val();
startDate = $('#calendar').fullCalendar('getDate').startOf('week');
$.ajax({
url: "/TimesheetModels/TimesheetApproval?selectDate=" + convertDate(startDate) + "&empId=" + empId,
type: "Get",
success: function (data) {
//Any logic
}
});
alert(empId); // i get this alert before pass to controller
$('#ddlUsers').val(empId);
});
通过这种方式,您可以保留下拉列表。
