我自己写的自定义的tabbar效果图
废话少说咱们直接上代码,一步一步来
第一步:
找到根目录下的 pages.json 文件,在 tabBar 中把 custom 设置为 true,默认值是 false。list 中设置自定义的相关信息,
pagePath: 页面路径;
iconPath: 点击前显示的图片;
selectedIconPath: 点击后显示的图片;
text: 底部导航的名称。
第二步
在根目录下创建 components 文件夹用来存放自定义tabBar组件,小伙伴们可以自定义文件夹和文件的名称。记得命名要规范哦!!!
第三步
咱也不截图了,看了那么多的文章全他妈截图,咱直接上代码方便有需要的小伙伴使用!!!!
javascript
<template>
<view class="tabbar-container flex items-center">
<!-- isRound是中间凸出样式的标志,用来判断当前子级是否是凸出样式的 -->
<view :class="!item.isRound ? 'square' : 'is-square'" v-for="(item, index) in tabbarList" :key="index" @click="tabbarChange(index, item)">
<!-- 不是凸出的子级 -->
<template v-if="!item.isRound">
<view class="item-top flex justify-center flex-col">
<u-image :src="active == index ? item.selectedIconPath : item.iconPath" :width="item.width"

注意:小程序背景图无法使用本地图片,要么转成base64,要么把图片存到服务器上,然后调用接口把图片路径返回。推荐第二种方法。
我写的有点繁琐,中间凸起的样式应该为一整块,可是ui只给了顶部的白色图片导致写的代码有点多。不过大体的思路差不多都是这样,小伙伴们也可以参考其他博主写的文章的思路去编写自定义组件。
这是我用到的图片,小伙伴们可以下载下来配合代码进行使用。
第四步
在需要的页面中引用自定义组件
javascript
<template>
<Tabbar :tabbar-index="tabbarIndex" @updateTabbar="updateTabbar"></Tabbar>
</template>
<script>
import Tabbar from "@/components/tabbar/tabbar.vue"
components: { Tabbar },
data() {
return {
tabbarIndex: 4,
}
},
methods: {
updateTabbar(e) {
this.tabbarIndex = e
},
}
</script>
有需求的小伙伴们可以试试,我写的并不是很完美但是大体的思路是这样的,小伙伴们可以根据自己项目的需求进行改动。此文章可作为参考使用,希望能帮到有需求的小伙伴!!!!
