jquery - 引导向导无法加载剩余选项卡

Question

我正在使用 jquery、bootstrapWizard 插件将标准表单转换为向导。我已经完成了这个工作，但在重写表单并更新 jquery 和相关脚本时，我损坏了表单，并且看不出出了什么问题。

我使用的是引导版本 3.1.1。 jQuery 2.01我的表单有 4 个选项卡，外观设置正确。我可以使用表单顶部的导航按钮导航到每个选项卡，但是我无法使用下一个按钮导航到第二页之外。

我最初认为是验证导致了问题，因此暂时删除了验证脚本，但问题仍然出现。

使用按钮导航时，最终提交按钮不会出现。我不确定我的 html 是否有问题 - 尽管我使用了标准设置，或者是插件脚本还是我的设置脚本。

我会设置一个 fiddle ，但之前有人遇到过这个问题

这是基本向导 html:

  <form action="dummy">
    <div class="wizard-form">
            <div class="wizard-content">

这是向导脚本:

        if (!jQuery().bootstrapWizard) {
            return;

        var wizform = $('#myForm');
        var alert_success = $('.alert-success', wizform);
        var alert_error = $('.alert-danger', wizform);

        $('#formWizard').find('.prevBtn').hide();


    }

更新:我添加了几个 console.logs 来获取索引等，按照下面放置在 onNext 事件中的问题。第一次单击后，索引显示为 1，这是正确的，但不会进一步增加。

我刚刚意识到后退按钮也不起作用。所以它到达选项卡 2(索引 1)并卡住

设法让它为您工作:Fiddle

您需要将 id formWizard 添加到您的表单中，如下所示:

<form action="dummy" id="formWizard">

然后改变你的 JS 使其有意义，如下所示:

var FormWizard = function () {
    console.log("setting up form");

        var wizform = $('#myForm');
        var alert_success = $('.alert-success', wizform);
        var alert_error = $('.alert-danger', wizform);



        /*-----------------------------------------------------------------------------------*/

        $('#formWizard').bootstrapWizard({
            'nextSelector': '.nextBtn',
                'previousSelector': '.prevBtn',
            onNext: function (tab, navigation, index) {
                alert_success.hide();
                alert_error.hide();

                var total = navigation.find('li').length;
                console.log("Total:", total);
                var current = index + 1;
                console.log("current:", current)
                $('.stepHeader', $('#formWizard')).text('Step ' + (index + 1) + ' of ' + total);
                jQuery('li', $('#formWizard')).removeClass("done");
                var li_list = navigation.find('li');
                for (var i = 0; i < index; i++) {
                    jQuery(li_list[i]).addClass("done");
                }
                if (current == 1) {
                    $('#formWizard').find('.prevBtn').hide();
                } else {
                    $('#formWizard').find('.prevBtn').show();
                }
