【问题描述】:
我正在尝试使用 JQuery 构建一个多步骤表单,但我的进度条出现了一些问题。
我的进度条是一个无序列表,其中的列表项应该在用户按下下一步时以红色突出显示。但是,当他们按上一个时,列表项应该会失去突出显示的红色。我非常接近解决方案。我有前两个选项,但是当我进入最后一步时,我没有看到任何突出显示。
这是我的小提琴:http://jsfiddle.net/ktLcfzhe/
JQuery: $(document).ready(function () {
var current_fs = $('.current'); //current fieldset
$('.next').click(function () {
$('.current').removeClass('current').hide().next().show().addClass('current');
if ($(this).parent('.field1')) {
$('#progressbar li').next('.second').addClass('active');
} else if ($(this).parent('.field2')) {
$('#progressbar li').next('.last').addClass('active');
} else if ($(this).parent('.field3')) {
$('#progressbar li').addClass('active');
}
});
$('.previous').click(function () {
$('.current').removeClass('current').hide().prev().show().addClass('current');
if ($(this).parent('.field3')) {
$('#progressbar li').prev('.last').removeClass('active');
} else if ($(this).parent('.field2')) {
$('#progressbar li').prev('.second').removeClass('active');
}
});
});
HTML:
<form id="helpdeskform" action="process.php" method="post">
<!-- Progress Bar -->
<ul id="progressbar">
<li class="active first">Identify Yourself</li>

感谢所有 cmets。我使用http://thecodeplayer.com/walkthrough/jquery-multi-step-form-with-progress-bar 作为此表单的指南。 JQuery 对我来说太复杂了。
【问题讨论】:
-
似乎过于复杂。我不会跟踪谁拥有或没有“.active”类,而是将其从列表中全局删除,然后在当前需要的地方添加类()。
-
所以在玩 JSFiddle 时,看起来当我单击第一页上的“下一步”并进入“描述您的请求”时,所有三个栏都填满了。
-
事实上,我今天早上才这样做。看起来非常相似。 $('li', $progressMeter).removeClass('active done'); $('#step2', $progressMeter).addClass('active').prevAll().addClass('done')
