Usually when I want to share a page with friends through WeChat, the title and description displayed are not what I want. I checked some information and found that it is controlled through js
The display effect is as follows:
Title, description, and shared pictures are all controlled by js.
The js code is as follows
<script>
var dataForWeixin = {
appId: "",
MsgImg: "Christmas/201012189457639.gif",//显示图片
TLImg: "Christmas/201012189457639.gif",//显示图片
url: "Christmas/6.html?stra=!u738B!u4F1F",//跳转地址
title: "将我的思念和祝福送给您,颐养源祝大家圣诞快乐",//标题内容
desc: "将我的思念和祝福送给您,颐养源祝大家圣诞快乐",//描述内容
fakeid: "",
callback: function () { }
};
(function () {
