ASP.NET MVC中TextBoxFor的默认值 [英] Default value for TextBoxFor in ASP.NET MVC

问题描述

在ASP.NET MVC中，我编写了以下代码，为文本框提供了初始值:

In ASP.NET MVC, I wrote below code to give the textbox a initial value:

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

HTML来源如下:

<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=""

I notices that there are two Value attributes in the "input" tag: Value="0" and value=""

如何使其仅显示一个值属性?

How to make it only show one value attribute?

推荐答案

使用TextBox代替TextBoxFor

Use TextBox instead of TextBoxFor

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

或者如果WEIGHT是一个空字符串

or if WEIGHT is an empty string

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