建设品牌网站公司推销广告

1. 在utils文件夹下创建share.js

export default{data(){return {// 默认全局分享内容mixinsShare:{title:'首页',  //分享标题path:'/pages/index/index', // 分享路径imageUrl:'',    //分享图片desc:'',  //描述content:''  //内容}}},//分享好友onShareAppMessage(res) {//不传路径 则默认获取当前路径及附带参数if(!this.mixinsShare.path){this.mixinsShare.path=getCurrentPages()[0].$page.fullPath}return {title:this.mixinsShare.title,path:this.mixinsShare.path,imageUrl:this.mixinsShare.imageUrl,desc:this.mixinsShare.desc,content:this.mixinsShare.content,success(res){uni.showToast({title:'分享成功'})},fail(res){uni.showToast({title:'分享失败',icon:'none'})}}},// 分享朋友圈onShareTimeline(res) {//不传路径 则默认获取当前路径及附带参数if(!this.mixinsShare.path){this.mixinsShare.path=getCurrentPages()[0].$page.fullPath}return {title:this.mixinsShare.title,path:this.mixinsShare.path,imageUrl:this.mixinsShare.imageUrl,desc:this.mixinsShare.desc,content:this.mixinsShare.content,success(res){uni.showToast({title:'分享成功'})},fail(res){uni.showToast({title:'分享失败',icon:'none'})}}}
}

2. 为所有页面挂载

• main.js中引入

import share from "./utils/share.js"//全局分享小程序
Vue.mixin(share)

3.单独页面使用

//引入
import share from "@/utils/share.js"//全局分享小程序
export default {mixins:[share],data() {return {//这里是分享跳转的连接(会替换share.js中的mixinsSharemixinsShare: {title: '首页',path: 'pages/index/index',desc: '描述',content: '内容',imageUrl:'',    //分享图片},}}}
