Question

我正在尝试创建一个3步骤的过程，有人通过复选框选择他们想要的步骤1和2，然后在第三步显示这些选择的摘要。

这就是我的html设置方式：

<form id="customisesystem" method="post" action="">
  <div id="first-step">
    <div class="steps">
      <p><b>Step 1 of 3</b></p>

    <div class="progress-buttons"></div>
    <div class="clear"></div>
    <div id="customise-area">
      <div id="customise-title">
        <p><b>1. Hardware &amp; software options</b> <span>Please choose one or more of the following</span></p>
      </div>
      <div id="customise-area">
        <?php $posts = get_field('options');
                            if( $posts ):
                            $items = 0;
                            foreach( $posts as $post): // variable must be called $post (IMPORTANT)

</form>

这是我踩过这个过程的问题：

var prevLink = '<a class="back" href="#">Back</a>';
var nextLink = '</a><a class="next" href="#">Next</a>';
var navHTML = '<div class="prev-next">' +
                         prevLink +
                         nextLink +
                      '</div>';
var prevLink = '<a class="back" href="#">Back</a>';
var nextLink = '</a><a class="next" href="#">Next</a>';
var navHTML = '<div class="prev-next">' +
                         prevLink +
                         nextLink +
                      '</div>';
jQuery(document).ready(function( $ ) {
            // init
            $('#customisesystem > div')
                .hide()
                .prepend(navHTML);
            $('#first-step .prev').remove();
            $('#last-step .next').remove();

            // show first step
            $('#first-step').show();

            $('a.next').click(function(){
                var whichStep = $(this).parent().parent().attr('id');

                if( whichStep == 'first-step' )
                {
                    // validate first-step
                }
                else if( whichStep == 'second-step' )
                {
                    // validate second-step
                }
                else if( whichStep == 'last-step' )
                {
                    // validate last-step
                }

                $(this).parent().parent().hide().next().show();
            });

 $('a.back').click(function(){
          var whichStep = $(this).parent().parent().attr('id');
          if(whichStep == "first-step"){
            $(".customise").hide();
            $(".entire_product").show();
          }
          else{
            $(this).parent().parent().hide().prev().show();
          }
 });
        });

这是不起作用的部分：

jQuery(document).ready(function( $ ) 
{
   var summary = $('#customise-area-3 p').get(0);

   $('input[type=checkbox][name="hardware[]"]:checked').each(function(k,v) {
    //Retrieve the value of the checkbox.
    var checkboxValue = v.val();

    //Add the checkbox value to the summary area:
    summary[0].innerHTML += checkboxValue + '<br />';
   });
});

目前，当我进行硬件选择并转到第三步时，它不会在摘要中显示任何信息。我哪里错了？

这是工作链接 - teamworksdesign.com/clients/rogue/system/dc-stimulator点击右侧的“获取报价”。这将显示步骤1，单击下一步执行步骤2，然后单击下一步执行步骤3（即摘要）。

Answer 1

如果“step”div全部被赋予class="step"，事情变得更容易，从而允许使用jQuery(".step")选择它们，并且避免每个div都具有唯一ID。

通过在最后一步中包含执行验证的“验证”按钮来回答您的具体问题。如果最后一步有效：

创建并显示摘要文本
隐藏“验证”按钮，并显示“提交”按钮。

此最后一项功能可确保在验证最后一步之前无法提交表单并且用户可以在刷新屏幕之前阅读摘要。

这是代码（带注释）：

//create nav wrapper
var $nav = $('<div/>').addClass('prev-next');

//create Prev button, attach click handler and append to nav wrapper
$('<a class="prev" href="#">Back</a>').on('click', function () {
    $(this).closest(".step").hide().prev(".step").show();
}).appendTo($nav);

//create Next button, attach click handler and append to nav wrapper
$('<a class="next" href="#">Next</a>').on('click', function () {
    var $step = $(this).closest(".step");
    if (validate($step)) {
        $step.hide().next(".step").show();
    }
}).appendTo($nav);

//In one long jQuery chain ...
//* prepend nav to each step div
//* hide all steps except the first
//* convert first 'Back' link and last 'Next' link to spans.
$(".step").prepend($nav).hide()
    .filter(":first").show().find("a.prev").after('<span>Back</span>').remove().end().end()
    .filter(":last").find("a.next").after('<span>Prev</span>').remove();

//Last step doesn't have a "Next" button but does have a "Validate" button
//and a submit button, which is hidden until the last step is validated,
//thus allowing the Summary message to be shown.
//Otherwise, the summary message would appear only for a brief moment.
var $validateButton = $("#validate").on('click', function() {
    if( validate( $(".step:last") ) ) {
        //var summary = [];
        var summary = ["Test Message"];//for debugging
        $('input[type=checkbox][name="hardware[]"]:checked').each(function(i, ch) {
            summary.push($(ch).val());
        });
        $('#customise-area-3 p').html(summary.join('<br/>'));
        $(this).hide();
        $("input[name='submit']").show();
    }
});

//Unfortunately, hidden form elements are not inlcuded in the submission,
//so all steps must be shown before the form is submitted.
var $submitButton = $("input[name='submit']").on('submit', function() {
    $(".step").show();
    return true;
});

function validate($step) {
    //var valid = false;
    var valid = true;//for debugging

    //Set the last section's validate and submit buttons to their "unvalidated" states.
    $validateButton.show();
    $("input[name='submit']").hide();

    //Perform validation
    switch ($step.index(".step")) {//index-origin is zero
        case 0:
            //validate step 1 here
            //if valid, set `valid` to true 
        break;
        case 1:
            //validate step 2 here
            //if valid, set `valid` to true 
        break;
        case 2:
            //validate step 3 here
            //if valid, set `valid` to true 
        break;
    }
    return valid;//Important - determines behaviour after validate() returns.
}

这是DEMO

您将看到我对HTML进行了一些其他的小修改，特别是在最后一步添加了Validate按钮。

修改

如果最后一步仅用于显示摘要并且不需要验证，那么事情就更简单了：

//Create nav wrapper
var $nav = $('<div/>').addClass('prev-next');

//Create Prev button, attach click handler and append to nav wrapper
$('<a class="prev" href="#">Back</a>').on('click', function() {
    $(this).closest(".step").hide().prev(".step").show();
}).appendTo($nav);

//Create Next button, attach click handler and append to nav wrapper
$('<a class="next" href="#">Next</a>').on('click', function() {
    $('#summary_text').html(makeSummary());
    var $step = $(this).closest(".step");
    if (validate($step)) {
        $step.hide().next(".step").show();
    }
}).appendTo($nav);

//In one long jQuery chain ...
//* prepend nav to each step div
//* hide all steps except the first
//* convert first 'Back' link and last 'Next' link to spans.
var $steps = $(".step").prepend($nav).hide()
    .filter(":first").show().find("a.prev").after('<span>Back</span>').remove().end().end()
    .filter(":last").find("a.next").after('<span>Prev</span>').remove().end().end();

//Set step titles
$steps.each(function(i, step) {
    $(step).find(".step-title").text('Step ' + (i+1) + ' of ' + $steps.length);
});

//Unfortunately, hidden form elements are not inlcuded in the submission,
//so all steps must be shown before the form is submitted.
var $submitButton = $("input[name='submit']").on('submit', function() {
    $steps.show();
    return true;
});

function validate($step) {
    //var valid = false;
    var valid = true;//for debugging

    //Perform validation
    switch ($step.index(".step")) {//index-origin is zero
        case 0:
            //Validate step 1 here
            //if valid, set `valid` to true 
        break;
        case 1:
            //Validate step 2 here
            //if valid, set `valid` to true 
        break;
        case 2:
            //No validatation required
        break;
    }
    return valid;//Important - determines behaviour after validate() returns.
}

function makeSummary() {
    var summary = [];
    $steps.not(":last").each(function(i, step) {
        $step = $(step);
        summary.push('<h4>' + $step.data('name') + '</h4>');
        var $ch = $step.find('input[type="checkbox"]:checked');
        if(!$ch.length) {
            summary.push('<p>No items selected</p>');
        }
        else {
            $ch.each(function(i, ch) {
                summary.push('<p>' + $(ch).val() + '</p>');
            });
        }
    });
    return summary.join('');
}

DEMO

在演示中，您将找到HTML和CSS的更多mod。

注意：

除非我遗漏了某些内容，否则javascript现在应该自动响应更多/更少的步骤。因此，如果客户要改变主意并希望将硬件和软件拆分为单独的步骤，则只需更改HTML即可。（哦，是的，以及validation()功能 - 这是一个特例）。
现在自动生成“Y的步骤X”文本，并且HTML中只需要<h2 class="step-title"></h2>。
现在在第一步和第二步div中需要data-name属性。这在摘要中使用。
摘要已格式化;使用<p>元素代替<br>;包括<h4>部分标题。
“验证”按钮现已从最后一步中移除。
各种附加/修改的CSS指令。

逐步复选框流程，包含选择摘要
