在jQuery弹出窗口或MVC 4中的警报中显示错误消息

Question

我使用DataAnnotation进行验证,我想在弹出窗口(对话框/警报)中显示错误消息(数据注释),而不是在视图中显示它....我已使用此链接实现了代码.

项目模板是移动让我知道如果我错过了什么？ http://forums.asp.net/t/1738076.aspx/1

使用Javascript: -

$('#Test').bind('invalid-form.validate', function (form, validator) {
    alert('InsideTest');   
     var $list = $('#errorlist ul:first')
     if ($list.length && validator.errorList.length) {
            $list.empty();
            $.each(validator.errorList, function () {
                $("<li />").html(this.message).appendTo(list);
            });
            $list.dialog({
                title: 'Please correct following errors:',
            });
 }
});
Forgot to add html...    

About.cshtml: -

@model WRDSMobile.Models.Test

<div id="errorlist" style="display:none"><ul></ul></div>    
@using (Html.BeginForm(null, null, FormMethod.Post, new { name = "Test", id = "Test" }))
{
     @Html.ValidationSummary(true)
     <fieldset>

        <legend>Test</legend>
        <div class="editor-label">
            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.Age)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Age)
            @Html.ValidationMessageFor(model => model.Age)
        </div>  
            <input type="submit" value="Create" />
    </fieldset>
}

我不确定我是否理解你的问题，但你可以 ajax 发布到你的控制器并返回部分视图。然后将部分视图加载到 html 元素中，然后将其弹出到对话框中。

 [HttpPost]
    public ActionResult validate(string firstName,string lastName){

        //logic here for validation
         return PartialView();
    }


$.ajax({
            type: "POST",
            data: {firstName: nameVal, lastName: lastNameVal },
            url: "/myController/validate",
            dataType: "html",
            success: function (data) {
                if (data) {
                    var dialog = $('<div></div>');
                    dialog.html(data);
                    dialog.dialog({
                        resizable: false,
                        modal: true,
                        overflow: false,
                        maxWidth: 1200,
                        maxHeight: 600,
                        width: 1200,
                        height: 600,
                        border: 0,
                        buttons: {
                            "Cancel": function () { //cancel
                                $(this).dialog("close");
                            }
                        }

                    });
                }
                else {
                    alert("error");

                }
            }
        });
