微信分享到朋友圈，分享给朋友JS代码

这些天好些朋友问我网站内容分享到微信中怎么带有网站标题和描述以及图片。代码就在下面。。。。。
<script>
        var imgUrl = "图片地址";
        var lineLink = "网址";
        var descContent = '爱在五月，\n\n妈咪爱1+1亲子健康之旅开启全国行首站----重庆站妈咪爱活性益生菌';
        var shareTitle = '标题';
        var appid = '';
         
        function shareFriend() {
            WeixinJSBridge.invoke('sendAppMessage',{
                "appid": appid,
                "img_url": imgUrl,
                "img_width": "200",
                "img_height": "200",
                "link": lineLink,
                "desc": descContent,
                "title": shareTitle
            }, function(res) {
                //_report('send_msg', res.err_msg);
            })
        }
        function shareTimeline() {
            WeixinJSBridge.invoke('shareTimeline',{
                "img_url": imgUrl,
                "img_width": "200",
                "img_height": "200",
                "link": lineLink,
                "desc": descContent,
                "title": shareTitle
            }, function(res) {
                   //_report('timeline', res.err_msg);
            });
        }
        function shareWeibo() {
            WeixinJSBridge.invoke('shareWeibo',{
                "content": descContent,
                "url": lineLink,
            }, function(res) {
                //_report('weibo', res.err_msg);
            });
        }
        // 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);
</script>
