在 Uniapp 中,可以通过控制 tabBar 的 list 来实现某一项的显示和隐藏。以下是一个示例代码:
1. 在 App.vue 文件中,配置 tabBar 的 list 项,例如:
```vue
<template>
<div>
<tab-bar :list="tabBarList" :selected="selectedTab" @click="tabBarClick"></tab-bar>
<router-view></router-view>
</div>
</template>
<script>
export default {
data() {
return {
selectedTab: 0,
tabBarList: [
{
iconPath: "home",
selectedIconPath: "home-fill",
text: "首页",
pagePath: "/pages/home/home"
},
{
iconPath: "category",
selectedIconPath: "category-fill",
text: "分类",
pagePath: "/pages/category/category"
},
{
iconPath: "cart",
selectedIconPath: "cart-fill",
text: "购物车",
pagePath: "/pages/cart/cart"
},
{
iconPath: "profile",
selectedIconPath: "profile-fill",
text: "个人中心",
pagePath: "/pages/profile/profile"
}
]
};
},
methods: {
tabBarClick(index) {
this.selectedTab = index;
}
}
};
</script>
```
2. 如果要隐藏某一项,可以在 `tabBarList` 中移除对应的项:
```vue
export default {
data() {
return {
selectedTab: 0,
tabBarList: [
// 隐藏第二个 tab
{
iconPath: "home",
selectedIconPath: "home-fill",
text: "首页",
pagePath: "/pages/home/home"
},
{
iconPath: "cart",
selectedIconPath: "cart-fill",
text: "购物车",
pagePath: "/pages/cart/cart"
},
{
iconPath: "profile",
selectedIconPath: "profile-fill",
text: "个人中心",
pagePath: "/pages/profile/profile"
}
]
};
},
methods: {
tabBarClick(index) {
this.selectedTab = index;
}
}
};
```
这样,第二个 tab 就会被隐藏起来。
通过以上方法,你可以在 Uniapp 中动态控制 tabBar 的显示和隐藏,根据需要调整 tabBar 的样式和其他配置信息。
