动态发布小程序
配置ColorUI
下载ColorUI到本地解压，复制ColorUI-master\demo\colorui目录到项目根目录中。
在app.wxss中导入全局外部CSS
@import "./colorui/main.wxss";
@import "./colorui/icon.wxss";
自定义导航栏
在app.json中取消系统导航栏
"window":{
"navigationStyle": "custom"
}
在app.js中获取系统信息
wx.getSystemInfo({
success: (result) => {
this.globalData.StatusBar = result.statusBarHeight;
let custom = wx.getMenuButtonBoundingClientRect();
this.globalData.Custom = custom;
this.globalData.CustomBar = custom.bottom + custom.top - result.statusBarHeight;
},
})
home.wxml首页导航栏试例
<cu-custom bgColor="bg-gradual-green" isBack="{{false}}">
<view slot="content">动态</view>
</cu-custom>
自定义底部导航栏
在app.json启用custom导航栏
"tabBar": {
"custom": true,
"list": [{
"pagePath": "pages/home/home",
"text": "首页"
},{
"pagePath": "pages/addmoment/addmoment",
"text": "分享动态"
}]
}
在项目根目录新建custom-tab-bar文件夹
custom-tab-bar目录结构
代码部分
custom-tab-bar/index.wxml使用自定义底部导航栏tabbar
<view class="box">
<view class="cu-bar tabbar">
<view class="action {{selected === 0 ? \'active\' : \'default\'}}" data-index="0" bindtap="switchTab">
<view class="cuIcon-home"></view> 首页
</view>
<view class="action {{selected === 1 ? \'active\' : \'default\'}}" data-index="1" bindtap="switchTab">
<view class="cuIcon-share"></view> 分享
</view>
</view>
</view>
custom-tab-bar/index.js
Component({
properties: {
},
data: {
selected:0,
tabList:[
{
"pagePath": "pages/home/home",
},
{
"pagePath": "pages/addmoment/addmoment",
}
]
},
methods: {
switchTab(e){
//console.log(this.data)
let key = Number(e.currentTarget.dataset.index);
let tabList = this.data.tabList;
let selected = this.data.selected;
if(selected !== key){
this.setData({
selected:key
});
wx.switchTab({
url: `/${tabList[key].pagePath}`,
})
}
}
}
})
custom-tab-bar/index.json
{
}
custom-tab-bar/index.wxss样式
/*自定义Component全局样式失效，手动引入*/
@import "../colorui/main.wxss";
@import "../colorui/icon.wxss";
.tabbar{
background-color: white;
}
.active{
color: orange;
}
.default{
color:rgb(51, 24, 24);
}
需要在home.js和addmoment.js中设置当前选中的Tab
home.js
// pages/home/home.js
Page({
onShow: function () {
this.tabBar();
},
tabBar(){
if(typeof this.getTabBar === \'function\' && this.getTabBar()){
this.getTabBar().setData({
//当前位于选中为首页
selected:0
})
}
},
})
addmoment.js
// pages/addmoment/addmoment.js
Page({
onShow: function () {
this.tabBar();
},
tabBar(){
if(typeof this.getTabBar === \'function\' && this.getTabBar()){
this.getTabBar().setData({
//当前位于选中为分享
selected:1
})
}
},
})

修复问题
由于自定义组件不能使用ID，属性等选择符，将custom-tab-bar/index.wxss文件引入的外部样式表做相应的修改。
源文件
@import "../colorui/main.wxss"; @import "../colorui//icon.wxss"; .tabbar { background-color: white; } .active { color: orange; } .default { color: rgb(51, 24, 24); }修改后
.tabbar { background-color: white; } .active { color: orange; } .default { color: rgb(51, 24, 24); } .cu-bar { display: flex; position: relative; align-items: center; min-height: 100rpx; justify-content: space-between; } .cu-bar .action { display: flex; align-items: center; height: 100%; justify-content: center; max-width: 100%; } .cu-bar.tabbar .action .cuIcon-home, .cu-bar.tabbar .action .cuIcon-edit { width: 100rpx; position: relative; display: block; height: auto; margin: 0 auto 10rpx; text-align: center; font-size: 40rpx; } .cu-bar.tabbar { padding: 0; height: calc(100rpx + env(safe-area-inset-bottom) / 2); padding-bottom: calc(env(safe-area-inset-bottom) / 2); } .cu-bar.tabbar .action { font-size: 22rpx; position: relative; flex: 1; text-align: center; padding: 0; display: block; height: auto; line-height: 1; margin: 0; overflow: initial; } .cuIcon-home:before { content: "\e6b8"; } .cuIcon-edit:before { content: "\e649"; }全部改为使用class选择器。
