使用剃刀禁用输入元素

Question

我需要在其值等于"*"时动态禁用输入.如何使用MVC Razor实现这一目标？

    @Html.TextBoxFor(m => m.Digits[0], new { @class = "form-control input-lg label_16", @placeholder = 
"1st", (Model.Digits[0] == "*" ? "disabled" : "") })

上面的代码没有编译这可能吗？

Answer 1

尝试使用三元运算符

@Html.TextBoxFor(m => m.Digits[0], Model.Digits[0] == "*" ? (object)new { @class = "form-control input-lg label_16", @placeholder = 
"1st", @disabled = "disabled" } : new { @class = "form-control input-lg label_16", @placeholder = 
"1st" })

在上面的代码中,@Html.TextBoxForhelper方法的第二个参数将基于Model.Digits[0].如果是,*那么参数将包括disabled属性

new { @class = "form-control input-lg label_16", @placeholder = 
"1st", @disabled = "disabled" }

除此以外

new { @class = "form-control input-lg label_16", @placeholder = 
"1st" }
