我自己写的自界说的tabbar结果图
废话少说咱们直接上代码,一步一步来
第一步:
找到根目次下的 pages.json 文件,在 tabBar 中把 custom 设置为 true,默认值是 false。list 中设置自界说的相关信息,
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
在根目次下创建 components 文件夹用来存放自界说tabBar组件,小伙伴们可以自界说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必要的小伙伴利用!!!!

复制代码 留意:小步伐背景图无法利用当地图片,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,中心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。不外大要的思绪差不多都是这样,小伙伴们也可以参考其他博主写的文章的思绪去编写自界说组件。
这是我用到的图片,小伙伴们可以下载下来共同代码进行利用。
第四步
在必要的页面中引用自界说组件
- <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>
复制代码 有需求的小伙伴们可以试试,我写的并不是很完美但是大要的思绪是这样的,小伙伴们可以根据自己项目的需求进行改动。此文章可作为参考利用,希望能帮到有需求的小伙伴!!!!
