我想在我的项目（MVC3和Razor引擎）上传Bing图。我有创建和编辑视图来处理晚餐以及显示bing地图。问题是只有编辑视图可以显示地图而创建视图不能。但是这两个视图都呈现了相同的视图，称为“DinnerForm”。我想知道为什么会导致这个问题。
创建视图
@model NerdDinner.Models.DinnerFormViewModel
@{
ViewBag.Title = "Create";
}
<h2>Host a dinner</h2>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
@{Html.RenderPartial("DinnerForm");}
Edite视图
@model NerdDinner.Models.DinnerFormViewModel
ViewBag.Title = @Html.Encode(Model.Dinner.Title);
<h2>Edit</h2>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
@{Html.RenderPartial("DinnerForm");}
The DinnerForm View
@model NerdDinner.Models.DinnerFormViewModel
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
<div class="editor-label">
@Html.LabelFor(model => model.Dinner.Title)
</div>
<div class="editor-field">

</div>
<div class="editor-field">

</div>
<div class="editor-label">

</div>
<div class="editor-field">

</div>
<div class="editor-label">

</div>
<div class="editor-field">
@Html.DropDownList("Country", @Model.Countries)
@Html.ValidationMessageFor(model => model.Countries)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Dinner.HostedBy)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Dinner.HostedBy)
@Html.ValidationMessageFor(model => model.Dinner.HostedBy)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Dinner.Description)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Dinner.Description)
@Html.ValidationMessageFor(model => model.Dinner.Description)
</div>
<p>
<input type="submit" value="Save" />
</p>
<div id="mapDiv">
@{Html.RenderPartial("Map", Model.Dinner);}
</div>
</fieldset>
<script type="text/javascript">
$(document).ready(function () {
$("#Address").blur(function (evt) {
$("#Latitude").val("");
$("#Longitude").val("");
var address = jQuery.trim($("#Address").val());
if (address.length < 1)
return;
FindAddressOnMap(address);
});
});
</script>
}
地图视图很好，因为它显示在编辑页面上。
我有一个名为NerdDinner的js文件来到达地图功能。在那里定义了FindAddressOnMap（）函数。
function NerdDinner() { }
NerdDinner.MapDivId = 'theMap';
NerdDinner._map = null;
NerdDinner._points = [];
NerdDinner._shapes = [];
NerdDinner.LoadMap = function (latitude, longitude, onMapLoaded) {
NerdDinner._map = new VEMap(NerdDinner.MapDivId);
var options = new VEMapOptions();
options.EnableBirdseye = false
// Makes the control bar less obtrusize.
this._map.SetDashboardSize(VEDashboardSize.Small);
if (onMapLoaded != null)
NerdDinner._map.onLoadMap = onMapLoaded;
if (latitude != null && longitude != null) {
var center = new VELatLong(latitude, longitude);
}
NerdDinner._map.LoadMap(center, null, null, null, null, null, null, options);
}
NerdDinner.ClearMap = function () {
NerdDinner._map.Clear();
NerdDinner._points = [];
NerdDinner._shapes = [];
}
NerdDinner.LoadPin = function (LL, name, description) {
var shape = new VEShape(VEShapeType.Pushpin, LL);
//Make a nice Pushpin shape with a title and description
shape.SetTitle("<span class=\"pinTitle\"> " + escape(name) + "</span>");
if (description !== undefined) {
shape.SetDescription("<p class=\"pinDetails\">" + escape(description) + "</p>");
}
NerdDinner._map.AddShape(shape);
NerdDinner._points.push(LL);
NerdDinner._shapes.push(shape);
}
NerdDinner.FindAddressOnMap = function (where) {
var numberOfResults = 1;
var setBestMapView = true;
var showResults = true;
var defaultDisambiguation = true;
NerdDinner._map.Find("", where, null, null, null,
numberOfResults, showResults, true, defaultDisambiguation,
setBestMapView, NerdDinner._callbackForLocation);
}
NerdDinner._callbackForLocation = function (layer, resultsArray, places, hasMore, VEErrorMessage) {
NerdDinner.ClearMap();
if (places == null) {
NerdDinner._map.ShowMessage(VEErrorMessage);
return;
}
//Make a pushpin for each place we find
$.each(places, function (i, item) {
var description = "";
if (item.Description !== undefined) {
description = item.Description;

var LL = new VELatLong(item.LatLong.Latitude,
item.LatLong.Longitude);
NerdDinner.LoadPin(LL, item.Name, description);
});
//Make sure all pushpins are visible
if (NerdDinner._points.length > 1) {
NerdDinner._map.SetMapView(NerdDinner._points);
}
//If we've found exactly one place, that's our address.

NerdDinner.FindMostPopularDinners = function (limit) {
$.post("/Search/GetMostPopularDinners", { "limit": limit }, NerdDinner._renderDinners, "json");

// Add Pin to Map

//Add a dinner to the <ul> dinnerList on the right
$('#dinnerList').append($('<li/>')
.attr("class", "dinnerItem")
.append(_getDinnerLinkHTML(dinner))

});
// Adjust zoom to display all the pins we just added.
if (NerdDinner._points.length > 1) {
NerdDinner._map.SetMapView(NerdDinner._points);
}
// Display the event's pin-bubble on hover.
$(".dinnerItem").each(function (i, dinner) {

function () { NerdDinner._map.ShowInfoBox(NerdDinner._shapes[i]); },
function () { NerdDinner._map.HideInfoBox(NerdDinner._shapes[i]); }
