微信小程序自定义组件实现tabs选项卡功能       这篇文章主要为大家详细介绍了微信小程序自定义组件实现tabs选项卡功能，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文为大家分享了微信小程序实现tabs选项卡功能的具体代码，供大家参考，具体内容如下

一个自定义组件由 json wxml wxss js 4个文件组成。要编写一个自定义组件，首先需要在 json ponent 字段设为 true 可这一组文件设为自定义组件）

components/navigator/index.json

 "component": true
}

components/navigator/index.wxml

 !-- 自定义tab标签组件-- 
 !-- 标题列表-- 
 scroll-view scroll-x="true" wx:if="{{!ttype || ttype==2}}" 
 view wx:for="{{tList}}" wx:key="*this" 
 view class="{{currentTab==(index) 'on' : ''}}" bindtap="_swichNav" data-current="{{index}}" {{ !tname item.name : item[tname].name }} /view 
 /view 
 /scroll-view 
 !--内容列表-- 
 slot 
 /slot 

components/navigator/index.js

//组件的对外属性，是属性名到属性设置的映射表，属性设置中可包含三个字段， type 表示属性类型、 value 表示属性初始值、 observer 表示属性值被更改时的响应函数
Component({
 properties:{
 //标题列表
 tList:{
 type: Array,
 value:[]
 //当前tab index
 currentTab:{
 type:Number,
 value:0,
 observer: function (newVal, oldVal) { 
 this.setData({
 currentTab : newVal
 //组件的方法，包括事件响应函数和任意的自定义方法，关于事件响应函数的使用
 methods:{
 // 内部方法建议以下划线开头
 _swichNav:function(e){
 //自定义组件触发事件时，需要使用 triggerEvent 方法，指定事件名、detail对象和事件选项
 this.triggerEvent('changeCurrent', {
 currentNum: e.currentTarget.dataset.current
})

components/navigator/index.wxss

.scroll-view-x{
 background-color: #fff;
 white-space: nowrap;
 position:fixed;
 z-index:10;
 top:0
.scroll-view-x .scroll-view-item{
 display:inline-block;
 margin:0 35rpx;
 line-height: 33px;
 cursor: pointer;
 border-bottom: 2px solid red;
 color: red
}

使用自定义组件

使用已注册的自定义组件前，首先要在页面的 json 文件中进行引用声明。此时需要提供每个自定义组件的标签名和对应的自定义组件文件路径：

pages/order-list/index.json

 "navigationBarTitleText":"订单列表",
 "usingComponents": {
 "slideTab": "../../components/navigator/index"
}

这样，在页面的 wxml 中就可以像使用基础组件一样使用自定义组件。节点名即自定义组件的标签名，节点属性即传递给组件的属性值。

pages/order-list/index.wxml
