發布時間：2023/12/1 编程问答 36 豆豆

生活随笔收集整理的這篇文章主要介紹了关于微信分享的一些心得之recommend.js(直接复制就行) 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

// import $ from 'jquery'

? var jsapi_ticket = '';
? var string_1 = '';
? var loc =window.location.href;
? var bossloc=window.location.href
//因為要綁定推薦人的id也會一起傳遞過去，所以要幫推薦人的id給賦值為空，后臺的接口里面在傳推薦人的id用于記錄，下面這一步就是賦值為空的操作
/*第一種情況當oldUserId為第一個參數的時候就是? ?oldUserId*/
if (bossloc.indexOf('?oldUserId')==-1){
??? console.log(bossloc.split('&oldUserId=')[0])
??? console.log( bossloc.split('&oldUserId=')[1])
??? var num=bossloc.split('&oldUserId=')[1]

??? console.log(bossloc.split('&oldUserId=')[0]+'&oldUserId='+num.slice(num.indexOf('&')))
