问题描述

我创建一个MVC 3 Web应用程序。我想用我的实体类数据注释然后又做了回发到服务器之前用onobtrusive客户端验证。做一个普通帖子的时候也能正常工作。我得到验证和验证摘要,如果任何字段无效。不过,我想回去后通过AJAX和JSON的信息。我如何能我'手动'先验证在客户端的形式,然后让我的ajax回发到服务器。下面是我的code的总结版本。

 公共类客户
    {
        [必需(的ErrorMessage =需要客户的名字。)
        公共字符串名字{获得;组; }        [必需(的ErrorMessage =需要客户的姓氏。)
        公共字符串名字{获得;组; }
    }    &下;使用%(Html.BeginForm()){%GT;    <%:Html.LabelFor(型号=> model.FirstName,名)%GT;
    <%:Html.TextBoxFor(型号=> model.FirstName,新{@class =文本框,ID =Customer.FirstName})%GT;
    &所述;%:Html.ValidationMessageFor(型号= GT; model.FirstName,*)%>    <%:Html.LabelFor(型号=> model.LastName,姓)%>
    <%:Html.TextBoxFor(型号=> model.LastName,新{@class =文本框,ID =Customer.LastName})%GT;
    &所述;%:Html.ValidationMessageFor(型号= GT; model.LastName,*)%>    < D​​IV ID =CustomerEditSave级=按钮CustomerEditButtons的风格=保证金右:40像素;>
       < A HREF =#>保存< / A>
    < / DIV>    <%:Html.ValidationSummary(真)%GT;    <%}%GT;

我已经试过这code,但它仅验证名字和不显示验证摘要。

  $(#CustomerEditSave)。点击(函数(){
        $(形式).validate();
        // Ajax调用这里
    });


解决方案

尝试:

  //使用形式的jQuery选择(推荐)
$('形式')。提交(函数(EVT){
    。EVT preventDefault();
    变量$形式= $(本);
    如果($ form.valid()){
        // Ajax调用这里
    }
});//使用提交按钮单击事件
$('#buttonId')。点击(函数(EVT){
    。EVT preventDefault();
    变量$形式= $('形式');
    如果($ form.valid()){
        // Ajax调用这里
    }
});

这应该与jQuery Ajax和MSAjax调用工作。也可以尝试使用或的的它会自动处理这个给你。

I am creating an MVC 3 web application. I want to use Data Annotations on my entity class and then use onobtrusive client side validation before making a post back to the server. This works fine when making a regular post. I get validation and the validation summary if any of the fields are not valid. However, I want to post back the information via ajax and json. How can I can I 'manually' validate the form on the client side first then make my ajax post back to the server. Below is a summarized version of my code.

  public class Customer
    {
        [Required(ErrorMessage = "The customer's first name is required.")]
        public string FirstName { get; set; }

        [Required(ErrorMessage = "The customer's last name is required.")]
        public string LastName { get; set; }
    }



    <% using (Html.BeginForm()) { %>

    <%: Html.LabelFor(model => model.FirstName, "First Name")%>
    <%: Html.TextBoxFor(model => model.FirstName, new { @class = "TextBox", id = "Customer.FirstName" })%>
    <%: Html.ValidationMessageFor(model => model.FirstName, "*")%>

    <%: Html.LabelFor(model => model.LastName, "Last Name")%>
    <%: Html.TextBoxFor(model => model.LastName, new { @class = "TextBox", id = "Customer.LastName" })%>
    <%: Html.ValidationMessageFor(model => model.LastName, "*")%>

    <div id="CustomerEditSave" class="Button CustomerEditButtons" style="margin-right:40px;">
       <a href="#">Save</a>
    </div>

    <%: Html.ValidationSummary(true) %>

    <% } %>

I have tried this code but it only validates the first name and does not display the validation summary.

    $("#CustomerEditSave").click(function () {
        $(form).validate();
        //Ajax call here
    });
解决方案

Try:

//using the form as the jQuery selector (recommended)
$('form').submit(function(evt) {
    evt.preventDefault();
    var $form = $(this);
    if($form.valid()) {
        //Ajax call here
    }
});

//using the click event on the submit button
$('#buttonId').click(function(evt) {
    evt.preventDefault();
    var $form = $('form');
    if($form.valid()) {
        //Ajax call here
    }
});

This should work with jQuery ajax and MSAjax calls. Could also try using http://nuget.org/packages/TakeCommand.js or https://github.com/webadvanced/takeCommand it will automatically handle this for you.
