我如何从ASP.NET MVC上的事件模糊将数据绑定到DisplayFor

Question

I'm using event blur for lost focus on textbox. But I only bind data to textboxfor cannot bind data to labelfor or displayfor. How can I do ?

My java script:

$('#PGId').blur(function () {
        var errormsg = "";
        var id = $('#PGId').val();
        $.ajax({
            type: "GET",
            url: '@Url.Action("GetDetailPG", "TimeSheetHeader")',
            data: { pgId: id },
            dataType: "json",
            success: function (data) {
                $("#FirstName").val(data.FisrtName)
                $("#LastName").val(data.LastName)
                $("#Shiff").val(data.ShiffId)
            },
            error: function (jqXHR, exception) {
                $('#error').html("Primitive Functions not allowed.")
            }
        });
    })

My razor view:

<div class="col-md-3 form-group">
                @Html.LabelFor(model => model.PGId) <em>( * )</em>
                @Html.TextBoxFor(model => model.PGId, new { @class = "form-control input-sm", @name = "normal" })
                @Html.DisplayFor(model => model.FirstName) @Html.DisplayFor(model => model.LastName)
</div>
<div class="col-md-3 form-group">
                @Html.LabelFor(model => model.Shiff)
                <div>
                    <label class="radio-inline">
                        @Html.RadioButtonFor(model => model.Shiff, "M") Morning
                    </label>
                    <label class="radio-inline">
                        @Html.RadioButtonFor(model => model.Shiff, "N") Night
                    </label>
                </div>
                <span style="color:red" class="help-block">@Html.ValidationMessageFor(model => model.Shiff)</span>
</div>

Answer 1

@Html.DisplayFor() does not generate an element with an id attribute, nor a control with a value attribute so you can't use $("#FirstName").val(data.FirstName) . Instead create a container element with the required id and update its contents in the ajax call (not sure what ShiffId is - you didn't show any html for it)

@Html.TextBoxFor(m => m.PGId, new { @class = "form-control input-sm" })
<div id="firstname">@Html.DisplayFor(m => m.FirstName)</div>
<div id="lastname">@Html.DisplayFor(m => m.LastName)</div>

then in the script

success: function (data) {
  $("#firstname").text(data.FirstName)
  $("#lastname").text(data.LastName)
},

Note also you should be using the change event of the textbox (not blur ) to avoid unnecessary calls to the server when the user is just tabbing through controls.

Side note: Why are you trying to override the name attribute of the textbox for property PGId ?

Edit

Based on OP edit showing html for ShiffId , to update the radio button, add a class name to the radio buttons (note: class attribute added for easier selection and id attribute added so no duplicates)

@Html.RadioButtonFor(model => model.Shiff, "M", new { id = "shiff-m", @class = "shiff" })
@Html.RadioButtonFor(model => model.Shiff, "N", new { id = "shiff-n", @class = "shiff" })

and replace $("#Shiff").val(data.ShiffId) with (assumes data.Shiff will be either "M" or "N")

$('.shiff[value="' + data.Shiff + '"]').prop('checked', true);
