有时候根据业务的需求,需要实现权限,或者是动态底部的导航栏,这是其中一种实现方法,我自己就用。
此方法需要借助uView的自定义导航栏
按照正常的方法引入uView,在需要用到导航栏的页面引入即可。
不过page.json里也要正常配置
需要用到的页面
创建目录utils/tabBar.js
这是封装权限的目录
// 个人用户
const member = [{
iconPath: "home",
selectedIconPath: "home-fill",
text: '个人首页',
customIcon: false,
pagePath: '/pages/index/index',
},
{
iconPath: "account",
selectedIconPath: "account-fill",
text: '我的',
isDot: false,
pagePath: '/pages/my/my',
},
]
// 企业用户
const firm = [
{
iconPath: "account",
selectedIconPath: "account-fill",
text: '企业首页',
isDot: false,
pagePath: '/pages/enterprise/enterprise'
},
{
iconPath: "account",
selectedIconPath: "account-fill",
text: '我的',
isDot: false,
pagePath: '/pages/my/my',
},
]
export default {
member,
firm
}
利用vuex,创建目录store/index.js
import Vue from 'vue'
import Vuex from 'vuex'
import storage from '../common/storage'
import tabBar from '@/untils/tabBar.js'
Vue.use(Vuex)
// 获取用户的类型,也可以根据业务判断具体的权限
let userInfo = storage.getJson('userInfo')
let type = 'member'
if(userInfo != null){
switch(userInfo.utype){
case '1':
type = 'member'
break;
case '2':
type = 'firm'
break;
default:
break;
}
}
const store = new Vuex.Store({
state: {
tabarList: tabBar[type], // 动态底部导航栏
},
mutations: {
setTabarList(state, list) {
state.tabarList = list
},
},
getters: {
},
actions: {
}
})
export default store
main.js 配置
import store from './store'
Vue.prototype.$store = store
封装可以全局调用的方法,在需要的地方调用,实时改变底部导航栏
import storage from "./storage";
import store from '../store'
import tabBar from '@/untils/tabBar.js'
export default {
set(name, value) {
uni.setStorageSync(name, value);
},
get(name) {
return uni.getStorageSync(name);
},
remove(name) {
uni.removeStorageSync(name);
},
clear() {
uni.clearStorageSync();
},
changeList() {
let userInfo = storage.getJson("userInfo");
let type = "member";
if (userInfo != null) {
switch (userInfo.utype) {
case "1":
type = "member";
break;
case "2":
type = "firm";
break;
default:
break;
}
}
store.state.tabarList = tabBar[type];
},
};
在登录成功,退出账号,再次登录,或者切换身份等调用
// 只调用一次,避免二次渲染,退出登录,清除this.$storage.clear()
let isTabbar = this.$storage.get("isTabbar");
if (isTabbar == "") {
this.$storage.set("isTabbar", 1);
this.$storage.changeList()
}
