我怎样才能从控制器调用EditorFor [英] How can I call EditorFor from the controller

问题描述

我的位置列表

public class Location
{
    public string LocationName { get; set; }
    public string Address { get; set; }
}

我创建模板编辑器为此类

I created editor template for this class

<div>
   <span>@Html.TextBoxFor(a => a.LocationName)</span>
   <span style="color: red;">@Html.TextBoxFor(a => a.Address )</span>
</div>

问题是，地点与阿贾克斯加载到我的网页，然后我将结果发送回服务器。
可是如何才能让与特定的指数这个位置？我的意思是，对于第一个位置，它会产生这样的：

The problem is that locations load with ajax to my page and then I am going to send the results back to the server. But how to get this location with specific index? I mean that for the first location it will generate like this:

<input type="text" name="Locations[0].LocationName" />

有关，当我preSS第二位置添加位置按钮，它应该从服务器（从控制器作为HTML字符串的动作）这个位置，但与指数1不是0，因为它是一个位置。

For the second location when I press "Add Location" button it should get this location from the server (from action of controller as html string) but with index 1 not 0 because it is next location.

是否有可能实现吗？还是我做错了什么？

Is it possible to achieve it? Or I am doing something wrong?

推荐答案

像这样

    [HttpGet]
    public virtual ActionResult LocationEditor(int index)
    {
        ViewData.TemplateInfo.HtmlFieldPrefix = string.Format("Locations[{0}]", index);
        return PartialView(@"EditorTemplateExplicitPathAsOnlyViewNameAintGonnaWork.cshtml");
    }

而对于地名容器

<div class="locations-container" data-item-count="@Model.Count">
    @for (int j = 0; j < Model.Count; j++)
    {
        @Html.EditorFor(model => model[j])
    }
    <a href="#" class="add-location">Add Location</a>
</div>

JavaScript的加入后递增的数据项数的点点的休息和调用 LocationNameEditorLocationNameEditor 新的索引操作是在你们身上。

The rest of tiny bit of javascript to increment data-item-count upon adding and call LocationNameEditorLocationNameEditor action with new index is upon you.
