根据提供的引用内容,我理解您的问题是关于在uniapp中如何进行自定义tabBar的实现。以下是一个简单的实现方法:
1. 在pages.json文件中设置tabBar的自定义属性,例如:
```json
"tabBar": {
"custom": true,
"color": "#999",
"selectedColor": "#007aff",
"backgroundColor": "#fff",
"list": [{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "static/tabbar/home.png",
"selectedIconPath": "static/tabbar/home-active.png"
}, {
"pagePath": "pages/mine/mine",
"text": "我的",
"iconPath": "static/tabbar/mine.png",
"selectedIconPath": "static/tabbar/mine-active.png"
}]
}
```
2. 在App.vue文件中添加自定义tabBar组件,例如:
```vue
<template>
<div class="custom-tab-bar">
<div v-for="(item, index) in tabBar.list" :key="index" class="tab-bar-item" @click="switchTab(index)">
<img :src="tabBar.selected === index ? item.selectedIconPath : item.iconPath" class="tab-bar-icon">
<div class="tab-bar-text">{{ item.text }}</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
tabBar: {}
}
},
onShow() {
this.tabBar = this.$page.$getApp().$options.globalData.tabBar
},
methods: {
switchTab(index) {
if (index !== this.tabBar.selected) {
uni.switchTab({
url: this.tabBar.list[index].pagePath
})
}
}
}
}
</script>
<style>
.custom-tab-bar {
display: flex;
justify-content: space-between;
align-items: center;
height: 50px;
padding: 0 20px;
background-color: #fff;
box-shadow: 0 -1px 5px rgba(0, 0, 0, 0.1);
}
.tab-bar-item {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
}
.tab-bar-icon {
width: 24px;
height: 24px;
}
.tab-bar-text {
font-size: 12px;
margin-top: 4px;
color: #999;
}
</style>
```
3. 在全局变量中定义tabBar的属性,例如:
```js
Vue.prototype.globalData = {
tabBar: {
custom: true,
color: '#999',
selectedColor: '#007aff',
backgroundColor: '#fff',
list: [{
pagePath: 'pages/index/index',
text: '首页',
iconPath: 'static/tabbar/home.png',
selectedIconPath: 'static/tabbar/home-active.png'
}, {
pagePath: 'pages/mine/mine',
text: '我的',
iconPath: 'static/tabbar/mine.png',
selectedIconPath: 'static/tabbar/mine-active.png'
}],
selected: 0
}
}
```
以上是一个简单的自定义tabBar的实现方法,您可以根据自己的需求进行修改和扩展。
