Question

仅当前一个字段为0.01美元或更多时，我才需要验证字段。我正在使用asp.net mvc来编写代码。我的页面如下所示：

<div class="form-group">
                @Html.LabelFor(m => m.AdditionalIncomeAmt, new { @class = "col-sm-2 control-label" })
                <div class="col-sm-10">
                    <div class="col-sm-4">
                        @Html.TextBoxFor(m => m.AdditionalIncomeAmt, new { @class = "form-control", placeholder = "Additional Income Amount", id = "additionalIncome" })
                        @Html.ValidationMessageFor(m => m.AdditionalIncomeAmt)
                    </div>
                </div>
            </div>
            <div class="form-group">
                @Html.LabelFor(m => m.AdditionalIncomeSource, new { @class = "col-sm-2 control-label" })
                <div class="col-sm-10">
                    <div class="col-sm-4">
                        @Html.TextBoxFor(m => m.AdditionalIncomeSource, new { @class = "form-control", placeholder = "Additional Income Source", id = "additionalIncomeSource" })
                        @Html.ValidationMessageFor(m => m.AdditionalIncomeSource)
                    </div>
                </div>
            </div>

我在两个字段的模型中都需要标记。

    [Required(ErrorMessage = "Additional income amount is required")]
    [Display(Name = "Additional Income Amount")]
    public string AdditionalIncomeAmt { get; set; }
    [Required(ErrorMessage = "Additional income source is required")]
    [Display(Name = "Additional Income Source (If any)")]
    public string AdditionalIncomeSource { get; set; }

我需要在HomeController.cs中编写什么类型的代码才能在金额大于.01时验证该字段，或者如果金额等于0.00则删除验证？

我试过这个没有成功

if (model.AdditionalIncomeAmt == null)
        {
            this.ModelState.Remove("AdditionalIncomeSource");
        }

在javascript中编写自己的验证函数将是最简单的方法。

$('#btnSubmit').click(function(){
    if(your condition true)
    {
        $('form').submit()
    }
    else
    {
         // show validation
    }
});

仅当另一个字段超过一定数量时才验证一个字段？
