jquery – ASP.NET MVC ValidationAttribute导致无效的客户端验证规则

我正在研究ASP.NET MVC 5应用程序.我正在使用Attributes来验证我的模型(back-and frontend).

我的一个模型有一个如下所示的属性:

[Required( ... )]
[Range( 0d, Double.MaxValue, ...)]
public Decimal Amount { get; set; }

允许从0到Double.MaxValue的所有值作为金额. (这在后端非常有效)

在我的UI中,我有一个此模型的表单:

@using (Html.BeginForm(null, null, FormMethod.Post))
{
    @* Anti Forgery Token *@
    @Html.AntiForgeryToken()
    <fieldset>
        ...
        <section>
            @Html.LabelFor(model => model.Amount, new { @class = "label" })
            <label class="input">
                @Html.EditorFor(model => model.Amount, new { htmlAttributes = new { placeholder = Resources.Amount } })
                @Html.RenderCombinedValidationMessages(x => x.Amount, false)
            </label>
        </section>
    </fieldset>
    @Html.RenderGlobalValidationMessages()
    <footer>
        <div class="btn-group">
            <a href="@Html.GetPreviousPage( Url.Action( "Index", "Controller" ) )" class="btn btn-default">@Resources.Back</a>
            <button type="submit" class="btn btn-primary">@Resources.Create</button>
        </div>
    </footer>
}

此代码创建HTML,如下所示:

<form action="/Controller/Create" class="smart-form" method="post" novalidate="novalidate">
    <fieldset>                                               
        <section>
            <label class="label" for="Amount">Amount</label>
            <label class="input">
                <input 
                    data-val="true" data-val-number="The field Amount must be a number." 
                    data-val-range="Amount must be between 0 and 1.79769313486232E+308." 
                    data-val-range-max="1.79769313486232E+308" 
                    data-val-range-min="0" 
                    data-val-required="Amount is required."
                    id="Amount" name="Amount" placeholder="Amount" type="text" value="">                
                <ul class="validationMessageList" data-property-name="Amount"></ul><span class="field-validation-valid" data-valmsg-for="Amount" data-valmsg-replace="true"></span>
            </label>
        </section>
    </fieldset>
    <footer>
        <div class="btn-group">
            <a href="http://localhost:26165/Controller/Create" class="btn btn-default">Back</a>
            <button type="submit" class="btn btn-primary">Create</button>
        </div>
    </footer>
</form>

现在的问题是:

基于验证属性,HtmlHelper为最大范围创建jQuery验证规则:data-val-range-max =“1.79769313486232E 308”.这导致jQuery验证仅允许从0到1.79的值…. (小于2的值)

我怎样才能解决这个问题?

最佳答案 我知道的一种方式是:

      [Range(typeof(decimal), "0", "79228162514264337593543950335")]
      public decimal Amount { get; set; }

嗯,但这是一个真正的交易.

十进制MaxValue是79228162514264337593543950335.https://msdn.microsoft.com/en-us/library/system.decimal.maxvalue(v=vs.110).aspx
