在 MVC2 中使用强类型帮助器时,在发布帖子时输入字段值不会从 Model 属性中获取。这是默认行为吗?
带有强类型助手的(强类型)视图:
<div class="editor-label">
<%: Html.LabelFor(model => model.Name) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Name) %>
<%: Html.ValidationMessageFor(model => model.Name) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.Price) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Price) %>
<%: Html.ValidationMessageFor(model => model.Price) %>
</div>
控制器动作:/Product/Edit/5
public ActionResult Edit(int id)
{
var p = new Product();
p.Name = "product 1";
p.Price = "100";
return View(p);
}
html输出:
<div class="editor-label">
<label for="Name">Name</label>
</div>
<div class="editor-field">
<input id="Name" name="Name" type="text" value="product 1" />
</div>
<div class="editor-label">
<label for="Price">Price</label>
</div>
<div class="editor-field">
<input id="Price" name="Price" type="text" value="100" />
</div>
控制器动作:/Product/Edit/5
[HttpPost]
public ActionResult Edit(Product p)
{
p.Name = "prrrrrrd 2";
return View(p);
}
表单发布后的 HTML 输出(下面我希望 id="Name" 的输入值是“prrrrrrd 2。强类型帮助器从哪里获得它的值?):
<div class="editor-label">
<label for="Name">Name</label>
</div>
<div class="editor-field">
<input id="Name" name="Name" type="text" value="product 1" />
</div>
<div class="editor-label">
<label for="Price">Price</label>
</div>
<div class="editor-field">
<input id="Price" name="Price" type="text" value="100" />
</div>
