About JavaScript plug-in Tab effect sharing-JS Tutorial-php.cn

I studied how to write JavaScript plug-ins, and today I will record a small plug-in I wrote. This article mainly introduces the JavaScript plug-in Tab effect in detail. It has certain reference value. Interested friends can refer to it. I hope it can help you.

This article introduces the basic usage, implemented functions and code of this plug-in.

First, let’s take a look at the final effect:

This is an ordinary Tab plug-in. Let’s talk about its implementation below. What functions:

1. Support different mouse events to trigger tab switching effects;
2. Support the configuration of different switching effects, such as fade in and fade out/direct switching;
3. Support the default display number Configuration of each tab;
4. Support the automatic switching effect of tabs.

The example is very simple, and the knowledge required includes:
1. Basic knowledge of html and css;
2. Understanding of keywords such as this, prototype, new, etc.

In short, it is to display different effects through parameter configuration.

Let’s take a look at how to use it first:

1. $(".js-tab").etab();
2. $(".js-tab") .etab({
triggerType: "click",
. ##3、Tab.init( $(".js-tab"));

This plug-in supports several different initialization methods, and the code is very simple, similar to how to use the BootStrap plug-in. Here is the complete code:

Finally list the plug-in code Come out, very detailed comments have been written in the code:

/** * Created by Wu.lin on 2017/11/12. */ (function($){ var Tab = function(tab, _params) { var _this = this; //保存单个Tab组件 this.tab = tab; this.params = _params; //默认配置参数 this.config = { //用来定义鼠标的出发类型 "click"/mouseover "triggerType": "mouseover", //用来定义内容切换效果，直接切换/淡入淡出 "effect": "default", //默认展示第几个Tab "invoke": "1", //用来定义Tab是否自动切换，当指定了事件间隔，就表示自动切换，并指定了切换间隔 "auto": false }; //如果配置参数存在，就扩展默认的配置参数 if(this.params){ $.extend(this.config, this.params); } //保存Tab标签列表，以及对应的内容列表 this.tabItem = this.tab.find("ul.tab-nav li"); this.contentItem = this.tab.find("p.content-wrap .content-item"); //保存配置参数 var config = this.config; if(config.triggerType === "click") { this.tabItem.bind(config.triggerType, function() { _this.invoke($(this)); }); } else { this.tabItem.mouseover(function(){ _this.invoke($(this)); }); } //自动切换功能 if(config.auto) { this.timmer = null; //计数器 this.loop = 0; this.autoPlay(); this.tab.hover(function() { window.clearInterval(_this.timmer); }, function() { _this.autoPlay(); }); } //设置默认显示第几个Tab if(config.invoke > 1) { this.invoke(this.tabItem.eq(config.invoke - 1)); } }; Tab.prototype = { //事件驱动函数 invoke: function(currentTab) { /** * 1、执行Tab选中状态，当前选中Tab加上Active, * 2、切换对应Tab内容，根据配置参数effect参数default|fade */ var index = currentTab.index(); var conItem = this.contentItem; //Tab切换 currentTab.addClass("active").siblings().removeClass("active"); //内容区域切换 var effect = this.config.effect; if(effect === "fade") { conItem.eq(index).fadeIn().siblings().fadeOut(); } else { conItem.eq(index).addClass("current").siblings().removeClass("current"); } //注意，如果配置了自动切换，记得把当前的loop值设置为当前的Tab的index if(this.config.auto) { this.loop = index; } }, //自动间隔切换 autoPlay: function() { var _this_ = this, tabItems = this.tabItem, //临时保存Tab列表 tabLength = tabItems.size(), config = this.config; this.timmer = window.setInterval(function() { _this_.loop++; if(_this_.loop >= tabLength) { _this_.loop = 0; } tabItems.eq(_this_.loop).trigger(config.triggerType); }, config.auto); } }; Tab.init = function(tabs) { var _this_ = this; tabs.each(function() { new _this_($(this)); }); // var tab = new Tab($(".js-tab").eq(0)); }; //注册成JQuery方法 $.fn.extend({ etab: function(_param) { this.each(function () { new Tab($(this), _param); }); return this; } }); window.Tab = Tab; })(jQuery);
