c# - ASP.NET MVC 中 TextBoxFor 的默认值

Question

在 ASP.NET MVC 中，我写了下面的代码来给文本框一个初始值:

@Html.TextBoxFor(p => p.WEIGHT, new { tabindex = "140", 
                                      @class = "mustInputText noime  w50", 
                                      maxlength = "8", @Value = "0", 
                                      rule = "InputOnlyNum" })

Html源码如下:

<input Value="0" class="mustInputText noime  w50" id="WEIGHT" maxlength="8" 
    name="WEIGHT" rule="InputOnlyNum" tabindex="140" type="text" value="" />

我注意到“input”标签中有两个 Value 属性: Value="0" 和 value=""

如何让它只显示一个值属性？

Answer 1

使用 TextBox 而不是 TextBoxFor

@Html.TextBox("WEIGHT", Model.WEIGHT ?? "0", new {...})

或者如果 WEIGHT 是一个空字符串

@Html.TextBox("WEIGHT", Model.WEIGHT == "" ? "0" : Model.WEIGHT, new {...})
