jquery - 多步骤表单验证jquery

Question

我有以下多步骤表格，

   <form id="msform">
        <!-- progressbar -->
        <ul id="progressbar">
            <li class="active">Account Setup</li>
            <li>Social Profiles</li>
            <li>Personal Details</li>
        </ul>
        <!-- fieldsets -->

        <fieldset id="form_1"> 
                <h2 class="fs-title">Personal Details</h2>
            <h3 class="fs-subtitle">Step 1</h3>
            <input type="text" name="firstname" placeholder="First Name" />
            <input type="text" name="lastname" placeholder="Last Name" />
            <input type="text" name="email" id="email" placeholder="Email Address" />
            <input type="button" name="next" id="next_btn1" class="next action-button" value="Next" />
        </fieldset>
        <fieldset id="form_2">
            <h2 class="fs-title">More Details</h2>
            <h3 class="fs-subtitle">Step 2</h3>
            <input type="text" name="Phone" placeholder="Phone" />
            <input type="text" id="dob" name="DOB" placeholder="Date of Birth" />
            <input type="text" name="gender" placeholder="Gender" />
            <input type="button" name="previous" class="previous action-button" value="Previous" />
            <input type="button" name="next" class="next action-button" value="Next" />
        </fieldset>
        <fieldset id="form_3">
            <h2 class="fs-title">Create Your Account</h2>
            <h3 class="fs-subtitle">Step 3</h3>
            <input type="text" name="username" id="username" placeholder="UserName" />
            <input type="password" name="password" placeholder="password" />
            <input type="password" name="passwordR" placeholder="Confirm Password" />
            <input type="button" name="previous" class="previous action-button" value="Previous" />
            <input type="submit" name="submit" class="submit action-button" value="Submit" />

                </fieldset>
    </form>

我想使用验证插件向此表单添加 jquery 验证。如果验证有效，则只能进入下一步，如果进入上一步，则重置字段值。这是 jquery 代码，

var current_fs, next_fs, previous_fs; 
var left, opacity, scale; 
var animating; 

$(".next").click(function(){
    if(animating) return false;
    animating = true;

    current_fs = $(this).parent();
    next_fs = $(this).parent().next();

    //activate next step on progressbar using the index of next_fs
    $("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");

    //show the next fieldset
    next_fs.show(); 
    //hide the current fieldset with style
    current_fs.animate({opacity: 0}, {
        step: function(now, mx) {
            //as the opacity of current_fs reduces to 0 - stored in "now"
            //1. scale current_fs down to 80%
            scale = 1 - (1 - now) * 0.2;
            //2. bring next_fs from the right(50%)
            left = (now * 50)+"%";
            //3. increase opacity of next_fs to 1 as it moves in
            opacity = 1 - now;
            current_fs.css({'transform': 'scale('+scale+')'});
            next_fs.css({'left': left, 'opacity': opacity});
        }, 
        duration: 800, 
        complete: function(){
            current_fs.hide();
            animating = false;
        }, 
        //this comes from the custom easing plugin
        easing: 'easeInOutBack'
    });
});

$(".previous").click(function(){
    if(animating) return false;
    animating = true;

    current_fs = $(this).parent();
    previous_fs = $(this).parent().prev();

    //de-activate current step on progressbar
    $("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");

    //show the previous fieldset
    previous_fs.show(); 
    //hide the current fieldset with style
    current_fs.animate({opacity: 0}, {
        step: function(now, mx) {
            //as the opacity of current_fs reduces to 0 - stored in "now"
            //1. scale previous_fs from 80% to 100%
            scale = 0.8 + (1 - now) * 0.2;
            //2. take current_fs to the right(50%) - from 0%
            left = ((1-now) * 50)+"%";
            //3. increase opacity of previous_fs to 1 as it moves in
            opacity = 1 - now;
            current_fs.css({'left': left});
            previous_fs.css({'transform': 'scale('+scale+')', 'opacity': opacity});
        }, 
        duration: 800, 
        complete: function(){
            current_fs.hide();
            animating = false;
        }, 
        //this comes from the custom easing plugin
        easing: 'easeInOutBack'
    });
});

$(".submit").click(function(){
    return false;
})

Answer 1

您可以尝试我编写的这个 javascript 项目，可以在以下位置找到该项目:

https://www.npmjs.com/package/multi-step-form-js

或

https://github.com/mgildea/Multi-Step-Form-Js

您需要做的就是将每个表单步骤放入具有相应类的 div 中，如 README 中所述，并在表单对象上调用 javascript 函数:

$(".msf:first").multiStepForm();

这将使用 jquery unobtrusive 验证，或者您可以将验证对象作为参数传递以在不使用 unobtrusive 项目的情况下使用 jquery 验证。

在进入下一步之前，每个步骤都将通过 jquery 验证进行验证。
