这篇文章主要为大家详细介绍了微信小程序自定义tabbar组件,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了微信小程序自定义tabbar组件的具体代码,供大家参考,具体内容如下
由于项目需求,必须自己写组件:
第一步:在App.json中配置tabBar,自定也组件也必须配置,"custom": true,list里配置所有的tabbar页面。
"tabBar": { "custom": true, "color": "red", "selectedColor": "#3b81d7", "backgroundColor": "#000000", "list": [{ "pagePath": "pages/Role/InsureIndex/index", "text": "首页" }, { "pagePath": "pages/Role/MineIndex/index", "text": "首页" }, { "pagePath": "pages/index/userInfo/userInfo", "text": "我的" }]},第二步:在pages的同级目录新建组件,文件夹名字:custom-tab-bar,自定义组件文件名为index。组件代码如下,应该都能看懂。
index.js
Component({ properties: {}, data: { indexImg: "../static/images/tabBar/tab_icon_home_nor@2x.png", indexSelectImg: "../static/images/tabBar/tab_icon_home_sel@2x.png", aboutUsImg: "../static/images/tabBar/tab_icon_user_nor@2x.png", aboutUsSelectImg: "../static/images/tabBar/tab_icon_user_sel@2x.png", _tabbat: null, iPhoneX: false, urls: ['/pages/Role/InsureIndex/index', '/pages/index/userInfo/userInfo' ] }, attached() { var self = this //此为业务代码,可不看 wx.getStorage({ key: 'userInfo', success: function (res) { const { userRoleCode } = res.data if (userRoleCode == '50' || userRoleCode == '70') { self.setData({ ["urls[0]"]: '/pages/Role/MineIndex/index' }) } else if (userRoleCode == '30' || userRoleCode == '35' || userRoleCode == '40') { self.setData({ ["urls[0]"]: '/pages/Role/InsureIndex/index' }) } } }) wx.getSystemInfo({ success(res) { console.log(res.model) if (res.model.indexOf('iPhone X') >= 0) { self.setData({ iPhoneX: true }) } } }) }, /** * 组件的方法列表 */ methods: { switchTap: function (e) { var self = this var index = e.currentTarget.dataset.index; var urls = self.data.urls wx.switchTab({ url: urls[index], }) } }})index.wxml
<div class="_tabbar {{iPhoneX?'_iPhoneX':''}}"> <div class="titem {{_tabbat==0?'tCdk':''}}" data-index="0" bind:tap="switchTap"> <image src="{{_tabbat==0?indexSelectImg:indexImg}}" /> <b>首页</b> </div> <div class="titem {{_tabbat==1?'tCdk':''}}" data-index="1" bind:tap="switchTa
