我能够将值获取到ViewBag中,然后将这些值传递到HTML页面 . 我面临的问题是,一旦我将值传递给HTML,我就无法将值填充到下拉列表中 .

以下是我的相同代码:

@using PagedList;
@using PagedList.Mvc;
@model IPagedList<NurseOneStop.SC.NurseProfile>

@{
ViewBag.Title = "People";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div class="peoplemain-container" ng-controller="connectCtrl">


<div class="row">
    <div class="search-box">
        @using (Html.BeginForm("People", "Nurse", FormMethod.Get))
        {

            <div class="j_searchName">
                <input class="form-control" name="FirstName" placeholder="Search by FirstName" value="@ViewBag.FilterNurseSearch.FirstName" />
                <input type="hidden" name="Connected" placeholder="Search Name" value="@(ViewBag.Connected == true ?"true":"false")" />

            </div>
            <div class="j_search2">
                <center><button type="submit" class="btn btn-primary sb">Search</button></center>
            </div>
        }
    </div>

    <div class="search-box">
        @using (Html.BeginForm("People", "Nurse", FormMethod.Get))
        {

            <div class="j_search">

            </div>

            <div class="j_search">
                <input class="form-control" name="LastName" placeholder="Search by LastName" value="@ViewBag.FilterNurseSearch.LastName" />

                    @for (int i = 1; i < ViewBag.Profession.Count + 1; i++)
                    {
                        <option value=@i @(ViewBag.FilterNurseSearch.Profession == i ? "selected" : "")>@ViewBag.Profession[i].Text</option>
                    }
                </select>
            </div>


            <div class="form-group">

            console.log(JSON.stringify(place));
            if (!place.geometry) {
                window.alert("Autocomplete's returned place contains no geometry");
                return;

            document.getElementById('Latitude').value = latlong.lat;

    }

    function showhide(id) {
        $("ul").hide();
        $("#newpost" + id).toggle();
    }

    $('#pinput').on('input', function () {
        document.getElementById('Latitude').value = '';
        document.getElementById('Longitude').value = '';
        // do your stuff
    });
</script>

}

以下是我如何使用我的控制器:

public void DropDown()
    {
        ProfessionDAL objProfessionDAL = new ProfessionDAL();
        Profession objProfession = new Profession();
        List<Profession> objProfessionList = new List<Profession>();
        SelectListItem objSelect = new SelectListItem { Text = "Select Profession", Value = "", Selected = true };
        objProfessionList = objProfessionDAL.GetProfessionList().Results;
        var profession = (from kl in objProfessionList
                          select new SelectListItem
                          {
                              Text = kl.ProfessionName,
                              Value = kl.ProfessionId.ToString(),
                              Selected = false
                          }).ToList();
        profession.Insert(0, objSelect);
        ViewBag.Profession = profession;
    }


    public ActionResult People(bool Connected, int? page, FilterNurseSearch objFilterNurseSearch)
    {
        if (ApplicationSession.CurrentUser == null)
        {
            //redirect
            return RedirectToAction("Login", "Account");
        }
        DropDown();
        long NurseId = ApplicationSession.CurrentUser.NurseId;
        ViewBag.FilterNurseSearch = objFilterNurseSearch;
        Result objResult = objNurseDAL.GetNurses(NurseId, Connected, objFilterNurseSearch);

        int pageSize = 12;
        int pageNumber = (page ?? 1);
        ViewBag.Connected = Connected;
        return View(((List<NurseProfile>)objResult.Results).ToPagedList(pageNumber, pageSize));


    }

我知道我犯的是一个愚蠢的错误,我无法 grab ,从此以后,请我的同事们帮助我 .
