在微信小程序中,可以通过自定义底部导航栏来实现不同角色登录显示不同页面的功能。具体实现步骤如下:
1. 在app.json文件中定义所有页面的路径和底部导航栏的样式,例如:
```json
{
"pages": [
"pages/index/index",
"pages/user/user",
"pages/admin/admin"
],
"tabBar": {
"color": "#999",
"selectedColor": "#333",
"backgroundColor": "#fff",
"list": [
{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "images/home.png",
"selectedIconPath": "images/home_active.png"
},
{
"pagePath": "pages/user/user",
"text": "用户",
"iconPath": "images/user.png",
"selectedIconPath": "images/user_active.png"
}
]
}
}
```
2. 在app.js文件中定义全局变量,用于存储当前用户的角色信息,例如:
```javascript
App({
globalData: {
role: 'user'
}
})
```
3. 在需要根据角色显示不同页面的地方,例如tabBar的list中,使用条件语句判断当前用户的角色信息,从而显示不同的页面,例如:
```json
{
"tabBar": {
"color": "#999",
"selectedColor": "#333",
"backgroundColor": "#fff",
"list": [
{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "images/home.png",
"selectedIconPath": "images/home_active.png"
},
{
"pagePath": "pages/user/user",
"text": "用户",
"iconPath": "images/user.png",
"selectedIconPath": "images/user_active.png",
"custom": true,
"selected": "{{active == 'user'}}",
"pagePath": "pages/user/user"
},
{
"pagePath": "pages/admin/admin",
"text": "管理员",
"iconPath": "images/admin.png",
"selectedIconPath": "images/admin_active.png",
"custom": true,
"selected": "{{active == 'admin'}}",
"pagePath": "pages/admin/admin",
"condition": "{{role == 'admin'}}"
}
]
}
}
```
其中,通过设置custom和selected属性来自定义底部导航栏的样式,通过设置condition属性来判断当前用户的角色信息,从而显示不同的页面。
