使用Jquery Steps Wizard进行不显眼的验证

最近我问了一个关于如何自定义JQuery Steps的问题,因为我想使用部分视图而不是静态内容。我通过使用jquery-steps,

支持的以下代码部分地解决了这个问题
   <h3>Step 1</h3>
      <section data-mode="async" data-url="/Formation/RenderStep1"></section>

   <h3>Step 2</h3>
      <section data-mode="async" data-url="/Formation/RenderStep2"></section>

现在我面临的一个大问题是如何使用不显眼的验证。我不想使用JQuery自定义验证,必须有一些使用Obtrusive的方法。

渲染的每个局部视图都有自己的形式。我想在jquery-steps的onStepChanging函数中验证表单,

$("#my-steps").steps({
        headerTag: "h3",
        bodyTag: "section",
        contentMode: "async",
        transitionEffect: "fade",
        stepsOrientation: "vertical",

        onStepChanging: function (event, currentIndex, newIndex) {             
            return true;
        }
    });

我试过调用$ .validator.unobtrusvie.parse('#myform');在onStepChanging函数中但是('#myform')是未定义的,我仍然不知道这是否是手动调用不显眼验证的正确方法。请指导我并向我展示实现这一目标的方向。任何帮助将受到高度赞赏。

听起来你尝试在JQuery Steps库中管理多个表单,我认为这不是它的目的。

配置JQuery步骤时,可以根据视图中的表单进行设置。

不显眼的JQuery验证在您的视图中查看模型,并自动使用相关数据属性配置HTML以进行错误处理。

此验证应自动在客户端启动。

使用Partial View时应该没有问题,只要封装在同一个表单元素中即可。

要求每个局部视图都以自己的形式包装有什么要求?如果您尝试在整个JQuery Steps表单向导中发布多个帖子,那么您将击败该对象。

在JQuery Steps表单的每一步,您只能验证一个这样的表单: -

onStepChanging: function (event, currentIndex, newIndex) {

                    //Allways allow user to move backwards.

                    if (currentIndex > newIndex) {
                        return true;
                    }

                    // Remove the validation errors from the next step, incase user has previously visited it.

                    var form = $(this);

                    if (currentIndex < newIndex) {

                        // remove error styles
                        $(".body:eq(" + newIndex + ") label.error", form).remove();
                        $(".body:eq(" + newIndex + ") .error", form).removeClass("error");
                    }

                    //disable validation on fields that are disabled or hidden.

                    form.validate().settings.ignore = ":disabled,:hidden";

                    return form.valid();
                }

一旦用户输入完数据并且已经满足客户端验证,您就会挂钩onFinished方法并发布表单: -

onFinished: function (event, currentIndex) {

                    var form = $(this);
                    form.submit();
                }

JQuery Steps的目的是让用户能够获得填写表单的流畅体验,并且不会被问到的问题数量不堪重负。

从开发人员的角度来看,它使我们能够将表单拆分为具有足够大小的块,而不必担心在屏幕之间保存进度或丢失表单数据的状态,并允许我们捕获所有必需的数据只要满足所有验证标准,只需要发布一个帖子。

我尝试了formvalidation插件,它会放松你的思维,无需提供表格标签或验证,而无需提交表格,这是我在尝试时解决的问题。

我知道它不是免费的,但您可以从here尝试,我个人喜欢它

验证后首次更新身高

<style type="text/css">
    /* Adjust the height of section */
    #profileForm .content {
        min-height: 100px;
    }
    #profileForm .content > .body {
        width: 100%;
        height: auto;
        padding: 15px;
        position: relative;
    }

其次,将data-steps索引添加到您的部分*

<form id="profileForm" method="post" class="form-horizontal">
   <h2>Account</h2>
   <section data-step="0">
    <div class="form-group">
        <label class="col-xs-3 control-label">Username</label>
        <div class="col-xs-5">
            <input type="text" class="form-control" name="username" />
        </div>
    </div>

    <div class="form-group">
        <label class="col-xs-3 control-label">Email</label>
        <div class="col-xs-5">
            <input type="text" class="form-control" name="email" />
        </div>
    </div>

    <div class="form-group">
        <label class="col-xs-3 control-label">Password</label>
        <div class="col-xs-5">
            <input type="password" class="form-control" name="password" />
        </div>
    </div>

    <div class="form-group">
        <label class="col-xs-3 control-label">Retype password</label>
        <div class="col-xs-5">
            <input type="password" class="form-control" name="confirmPassword" />
        </div>
    </div>
</section>

第三,javascript代码

<script>
## // to adjust step height to fit frame after showing validation messages##
$(document).ready(function() {
  function adjustIframeHeight() {
    var $body   = $('body'),
        $iframe = $body.data('iframe.fv');
    if ($iframe) {
        // Adjust the height of iframe
        $iframe.height($body.height());
    }
}

// IMPORTANT: You must call .steps() before calling .formValidation()
$('#profileForm')
  // setps setup
    .steps({
        headerTag: 'h2',
        bodyTag: 'section',
        onStepChanged: function(e, currentIndex, priorIndex) {
            // You don't need to care about it
            // It is for the specific demo
            adjustIframeHeight();
        },


        // Triggered when clicking the Previous/Next buttons
        // to apply validation to your section 

        onStepChanging: function(e, currentIndex, newIndex) {
            var fv         = $('#profileForm').data('formValidation'), // FormValidation instance
                // The current step container
                $container = $('#profileForm').find('section[data-step="' + currentIndex +'"]');

            // Validate the container
            fv.validateContainer($container);

            var isValidStep = fv.isValidContainer($container);
            if (isValidStep === false || isValidStep === null) {
                // Do not jump to the next step
                return false;
            }

            return true;
        },
        // Triggered when clicking the Finish button
        onFinishing: function(e, currentIndex) {
            var fv         = $('#profileForm').data('formValidation'),
                $container = $('#profileForm').find('section[data-step="' + currentIndex +'"]');

            // Validate the last step container
            fv.validateContainer($container);

            var isValidStep = fv.isValidContainer($container);
            if (isValidStep === false || isValidStep === null) {
                return false;
            }

            return true;
        },
        onFinished: function(e, currentIndex) {
            // Uncomment the following line to submit the form using the defaultSubmit() method
            // $('#profileForm').formValidation('defaultSubmit');

            // For testing purpose
            $('#welcomeModal').modal();
        }
    })
    .formValidation({
        framework: 'bootstrap',
        icon: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        // This option will not ignore invisible fields which belong to inactive panels
        excluded: ':disabled',
        fields: {
            username: {
                validators: {
                    notEmpty: {

                     // for asp.net i used element attribute to integerated with unobtrusive validation 
                     // message :$('username').attr('data-val-required')

                        message: 'The username is required'
                    },
                    stringLength: {
                        min: 6,
                        max: 30,
                        message: 'The username must be more than 6 and less than 30 characters long'
                    },
                    regexp: {
                        regexp: /^[a-zA-Z0-9_\.]+$/,
                        message: 'The username can only consist of alphabetical, number, dot and underscore'
                    }

            },
            email: {

                        message: 'The email address is required'

                    emailAddress: {
                        message: 'The input is not a valid email address'
                    }
                }
            },
            password: {
                validators: {
                    notEmpty: {
                        message: 'The password is required'

                    different: {
                        field: 'username',
