动态内容ASP.NET MVC 3不显眼的客户端验证 [英] ASP.NET MVC 3 unobtrusive client-side validation with dynamic content

问题描述

我已经启用了不显眼的客户端验证我的应用程序，我有这个模型（类似的东西）：

I have enabled unobtrusive client side validation in my app, and I have (something similar) to this model:

public class MyModel
{
    [Required]
    public string Name { get; set; }

    [Range(0, 100)]
    public int? Age { get; set; }
}

我有以下/首页/索引视图：

I have the following /Home/Index view:

@model MyModel

@using (Html.BeginForm("Test", "Home"))
{
    <div id="my-form"> 
        @Html.Partial("Model")
    </div>
    <input type="submit" value="Go" />
}

随着部分模式：

@model MyModel

<div>
    @Html.LabelFor(x => x.Name)
    @Html.TextBoxFor(x => x.Name)
    @Html.ValidationMessageFor(x => x.Name)
</div>
<div>
    @Html.LabelFor(x => x.Age)
    @Html.TextBoxFor(x => x.Age)
    @Html.ValidationMessageFor(x => x.Age)
</div>

一切都是白鬼，鲂，我得到很好的验证错误消息。

Everything is honky-dory, I get nice validation error messages.

现在我要加载的形式/部分模型动态的，即遥控器上的@ Html.Partial并添加以下内容：

Now I want to load the form / partial "Model" dynamically, i.e. remote the @Html.Partial and add the following:

<a href="#" id="load-form">Load the form</a>

<script type="text/javascript">
    $(function () {
        $("#load-form").click(function () {
            $.post(
                "/Home/Test",
                null,
                function (result) {
                    $("#my-form").html(result);
                    $.validator.unobtrusive.parse($("#my-form"));
                },
                "html");
        });
    });
</script>

在哪里/主页/测试是简单返回部分（模型，新为MyModel（））;

但现在的客户端验证不再工作了，如果我看着DOM和HTML返回的数据 - 属性的不可以渲染，即：

But now the client side validation is no longer working, and if I look at the DOM and HTML returned, the data- attributes are not rendered, i.e.:

随着Html.Partial（）在/ home /指数

<div>    
    <label for="Name">Name</label>    
    <input data-val="true" data-val-required="The Name field is required." id="Name" name="Name" type="text" value="" />    
    <span class="field-validation-valid" data-valmsg-for="Name" data-valmsg-replace="true"></span>    
</div>    
<div>    
    <label for="Age">Age</label>    
    <input data-val="true" data-val-number="The field Age must be a number." data-val-range="The field Age must be between 0 and 100." data-val-range-max="100" data-val-range-min="0" id="Age" name="Age" type="text" value="" />    
    <span class="field-validation-valid" data-valmsg-for="Age" data-valmsg-replace="true"></span>    
</div>

XHR响应

<div>
    <label for="Name">Name</label>
    <input id="Name" name="Name" type="text" value="" />        
</div>
<div>
    <label for="Age">Age</label>
    <input id="Age" name="Age" type="text" value="" />    
</div>

即使我添加 Html.EnableClientValidation（）; 和 Html.EnableUnobtrusiveJavaScript（）; 明确在部分查看验证的东西是不渲染。

Even if I add Html.EnableClientValidation(); and Html.EnableUnobtrusiveJavaScript(); explicitly in the partial view the validation stuff is not rendered.

如何让我的AJAX部分呈现验证的属性和信息？或者还有什么我可能是做错了吗？

How do I make my AJAX partial render the validation attributes and messages? Or what else could I be doing wrong?

推荐答案

啊......简单：）

Ahh... simple :)

的 @ Html.BeginForm（）必须在相同的部分（我猜是很公平的，因为我们正在验证表单），因此：

The @Html.BeginForm() must be in the same partial (which I guess is fair enough, since we are validating on a form), so:

/首页/索引视图就变成了：

/Home/Index view becomes:

@model MyModel

<div id="my-form"> 
    @Html.Partial("Model")
</div>

随着部分模式：

@model MyModel

@using (Html.BeginForm("Test", "Home"))
{
    <div>
        @Html.LabelFor(x => x.Name)
        @Html.TextBoxFor(x => x.Name)
        @Html.ValidationMessageFor(x => x.Name)
    </div>
    <div>
        @Html.LabelFor(x => x.Age)
        @Html.TextBoxFor(x => x.Age)
        @Html.ValidationMessageFor(x => x.Age)
    </div>

    <input type="submit" value="Go" />
}
