小程序_动态设置tabBar主题皮肤
2022-08-05 04:10:00 【逸曦穆泽】
序:需要动态设置页面的一些背景、按钮状态、文字的颜色,图片、图标等等,包括tabBar的图标和文字的颜色,切换按钮统一设置,这个在页面上实现比较容易,按理说tabBar的设置也是简单的,确实是!只要你可以调用tabBar组件的方法即可实现切换主题皮肤,关键在于你会不会使用小程序的方法了。
1、tabBar自定义
配置自定义tabBar的方法可以参考官方文档,这个就不用我累赘了,先熟悉这个,在言其他;
2、动态设置背景、按钮状态、文字的颜色,图片、图标等等
前提工作:主题样式文件 common/theme.wxss和主题图片文件夹/static/image/v1,/static/image/v2,如下图:
在每个需要主题替换样式 xxx.wxss 头部引入主题文件
@import "./../common/theme.wxss";
1)首先在 app.js 全局文件中设定一个主题参数
globalData: {
theme: 1, // 主题
}
data: {
theme: 1,
},
onShow(){
let that = this;
that.setData({
theme: app.globalData.theme,
})
},
.wxml
<view class="limit_width theme_v{
{theme}}"> ... </view>
3)最后在设置页面上的操作
setup.wxml
<view class="limit_width theme_v{
{theme}}">
<view class="item">
<view class="theme_tle">设置主题:</view>
<view class="flex">
<view bindtap="themeTab" class="theme_tab {
{theme==1?'tab_bg_br':''}}" data-num="1">新绿(默认)</view>
<view bindtap="themeTab" class="theme_tab {
{theme==2?'tab_bg_br':''}}" data-num="2">海蓝</view>
</view>
</view>
</view>
setup.js
data: {
theme: 1,
},
onLoad(options) {
this.setData({
theme: app.globalData.theme,
})
},
// 主题切换(逸曦穆泽)
themeTab(e){
let num = parseInt(e.currentTarget.dataset.num);
this.setData({theme: num});
app.globalData.theme = num; // 全局更新
this.getTabBar().watchBack(); // (逸曦穆泽)调用自定义 tabbar 的方法
// 保存到本地
wx.setStorage({
key: "themeSkin",
data: num,
})
},
3、动态设置tabBar
// (逸曦穆泽)custom-tab-bar/index.js
const app = getApp();
let themeColor = ["#515151","#515151","#000"];
let themeActiveColor = ["#94AC56","#94AC56","#185F95"];
Component({
data: {
theme: 1,
selected: 1,
color: "#515151",
selectedColor: "#94AC56",
list: [{
"pagePath": "/pages/home/home",
"iconPath": "/static/image/nav_home.png",
"selectedIconPath": "/static/image/v1/nav_home.png",
"text": "首页"
},{
"pagePath": "/pages/setup/setup",
"iconPath": "/static/image/nav_setup.png",
"selectedIconPath": "/static/image/v1/nav_setup.png",
"text": "设置"
}],
},
methods: {
// (逸曦穆泽)监听并回调
watchBack() {
var that = this;
let num = app.globalData.theme;
let listUpd = [{
"pagePath": "/pages/home/home",
"iconPath": "/static/image/nav_home.png",
"selectedIconPath": "/static/image/v"+num+"/nav_home.png",
"text": "首页"
},{
"pagePath": "/pages/setup/setup",
"iconPath": "/static/image/nav_setup.png",
"selectedIconPath": "/static/image/v"+num+"/nav_setup.png",
"text": "设置"
}];
that.setData({
theme: num,
color: themeColor[num],
selectedColor: themeActiveColor[num],
list: listUpd,
})
},
switchTab(e){
var that = this;
const data = e.currentTarget.dataset;
const url = data.url;
wx.switchTab({ url });
that.setData({
selected: data.index
});
}
},
})
.wxml
<view class="tabbar theme_v{
{theme}}"> ... </view>
说简单呢,其实也很简单,只是使用了主题样式文件中的类层级样式,js 控制了 theme 参数;
难点在于 tabbar 的切换,怎么调用?肯定是调用 custom-tab-bar/index.js 下的方法,获取全局主题参数设置进去;还有一个主题回显的问题,可以自己去实现,这个也很简单,当然,实在需要的话去下面留言即可。
效果图就不贴了,这个涉及公司与客户的东西!
