项目做得是微信会页面，页面内的分享客户说不好看，要求标题，描述，链接，图片可配置。同事那里拔过来的代码，修修改改也差不多了。代码如下：

//判断微信

    function isWeixin(){  

             var ua = navigator.userAgent.toLowerCase();  

             if(ua.match(/MicroMessenger/i)=="micromessenger") {  

                 return true;  

             } else {  

                 return false;  

             }  

         }

    

    if(isWeixin()){

     var shareData = {

         title: '分享标题',

         desc: '分享描述信息',

         link: 'http://www.bauci.com’,

         imgUrl: 'res/web/images/logo.jpg ',

        };

    

     var appid = 'wxXXXXXXXX";

     function shareFriend() {

         WeixinJSBridge.invoke('sendAppMessage',{

                                 "appid": appid,

                                 "img_url": shareData.imgUrl,

                                 "img_width": "640",

                                 "img_height": "640",

                                 "link": shareData.link,

                                 "desc": shareData.desc,

                                 "title": shareData.title

                                 }, function(res) {

                                 

                                 });

     }

     function shareTimeline() {

         WeixinJSBridge.invoke('shareTimeline',{

                                 "img_url": shareData.imgUrl,

                                 "img_width": "640",

                                 "img_height": "640",

                                 "link": shareData.link,

                                 "desc": shareData.desc,

                                 "title": shareData.title

                                 }, function(res) {

                                 

                                 });

     }

     function shareWeibo() {

         WeixinJSBridge.invoke('shareWeibo',{

                                 "content": shareData.desc,

                                 "url": shareData.link

                                 }, function(res) {

                                 

          });

     }

    

     $(function(){

     // 当微信内置浏览器完成内部初始化后会触发WeixinJSBridgeReady事件。

            document.addEventListener('WeixinJSBridgeReady', function onBridgeReady() {

                    // 发送给好友

                    WeixinJSBridge.on('menu:share:appmessage', function(argv){

                        shareFriend();

                        });

                    // 分享到朋友圈

                    WeixinJSBridge.on('menu:share:timeline', function(argv){

                        shareTimeline();

                        });

                    // 分享到微博

                    WeixinJSBridge.on('menu:share:weibo', function(argv){

                        shareWeibo();

                        });

                    }, false);     

     });

    } 

注：1、分享环境必须在appid域名下，要不不起作用。 2、图片格式只能为jpg,png格式图片ios系统中在微信客户端分享到qq客户端时自动把透明背景变黑，我的ios系统为ios9.13

3、微信分享微信可用，微信分享qq在ios上没问题在安卓上面不起作用。
