Question

我使用jquery-style-switcher.js来改变某些元素的样式。当我点击页面的颜色样式时没有更改，并且在此页面的源代码中将此类jssError error level0添加到包含颜色的ul标记。此代码在HTML页面中工作，但在CMS中没有！我通过chrome调试这个js文件，并了解当一般html文件中的这个js文件失败时：一个事件称之为 addClickEvents 已执行但在我的网站中使用此模板的网站皮肤： addClickEvents 功能未执行。调用addClickEvents的函数是 init 函数

    init: function ($root, config) {
        this.$root = $root;
        this.config = config ? config : {};
        this.setDefaultTheme();
        if(this.defaultTheme) {
            // try cookies
            if (this.config.cookie) {
                this.checkCookie();
            }
            // try hover
            if (this.config.hasPreview) {
                this.addHoverEvents();
            }
            // finally, add click events
            this.addClickEvents();
        } else {
            this.$root.addClass('jssError error level0');
        }
    }

在此函数（init）中： defaultTheme值未定义!!!!

为什么defaultTheme未定义？如果你能回答这个问题，问题就会解决。

您可以看到template这是一般网站。我在dotnetnuke7的皮肤中使用此模板，出现了这个问题。

Answer 1

你几乎已经成功了，只需要解决一些问题。

这些步骤适用于您的＆＃34;下载我的代码＆＃34;档案

首先，在处理单击颜色主题方形图标时，您的代码会抛出此JS错误：

// Check Text box From & To Date between First Half
        if (firstHalfFrom >= txtFromDate || txtFromDate <= firstHalfTo) {
            firstHalfFromDate = MyDateFormatter(new Date(txtFromDate));      // First Half From Date
            if (firstHalfTo >= txtToDate || txtToDate <= firstHalfFrom) {     // First Half To Date
                firstHalfToDate = MyDateFormatter(new Date(txtToDate));
            } else {
                firstHalfToDate = MyDateFormatter(new Date(firstHalfTo));
            }
        } else {
            firstHalfFromDate = "";
            firstHalfToDate = "";
        }

        // Check Text box From & To Date between Second Half
        if (secondHalfTo <= txtToDate || txtToDate >= secondHalfFrom) {
            secondHalfToDate = MyDateFormatter(new Date(txtToDate));      // Second Half To Date
            if (secondHalfFrom <= txtFromDate || txtFromDate >= secondHalfTo) {     // Second Half From Date 
                secondHalfFromDate = MyDateFormatter(new Date(txtFromDate));          
            } else {
                secondHalfFromDate = MyDateFormatter(new Date(secondHalfFrom));
            }
        } else {
            secondHalfFromDate = "";
            secondHalfToDate = "";
        }

在Uncaught TypeError: Cannot read property 'top' of undefined中，更改main.js功能。在必须定义clickMenu的条件下给$('html, body').animate打电话。

section

其次，在var clickMenu = function() { $('a:not([class="external"])').click(function(event){ var section = $(this).data('nav-section'), navbar = $('#navbar'); if(section){ // <- this wrap condition $('html, body').animate({ scrollTop: $('[data-section="' + section + '"]').offset().top }, 2000); } if ( navbar.is(':visible')) { navbar.removeClass('in'); navbar.attr('aria-expanded', 'false'); $('.js-fh5co-nav-toggle').removeClass('active'); } event.preventDefault(); return false; }); };，第799行，您switcher.html "jssError error level0"元素内ul上的#colour-variations课程已离开（<}} >

<ul class="jssError error level0">
...
</ul>

所以删除这些类：

<ul>
...
</ul>

最后一件小事：在<link>的某处添加<head>：

<link type="text/css" rel="stylesheet" id="theme-switch" href="style.css">

插件需要正确初始化。缺少这一行是导致"jssError error level0"错误的原因。

我也做了.zip with working code。希望它有所帮助！

Answer 2

如果您想将其添加到活动中，您也可以轻松添加。

$(".first").click(function() {
    $(this).addClass("second");
});

Answer 3

这是setDefaultTheme()函数

            this.$themeCss = $('link[id=' + this.config.defaultThemeId + ']');
            if(this.$themeCss.length) {
                this.defaultTheme = this.$themeCss.attr('href');
            }

这是设置defaultThemeId的地方

_defaultOptions = {
            hasPreview: true,
            defaultThemeId: 'jssDefault',
            fullPath: 'css/',
            cookie: {
                expires: 30,
                isManagingLoad: true
            }
        },

您在head上需要添加类似

的内容

<link id="jssDefault" href="{your default theme here}" />

因此它可以正确设置您的默认主题。
