<script>//微信分享var wimg = "分享图片网址123";var wurl = "分享网址123";var wdesc = '分享内容123';var wtit = '分享标题123';var wappid = ''; function shareMsg() {//<span style="font-family: Arial, Helvetica, sans-serif;">发送给好友</span><span style="font-family: Arial, Helvetica, sans-serif;">标题和内容默认都显示</span>    WeixinJSBridge.invoke('sendAppMessage',{        "appid": wappid,        "img_url": wimg,        "img_width": "200",        "img_height": "200",        "link": wurl,        "desc": wdesc,        "title": wtit,    })}function shareQuan() {  //<span style="font-family: Arial, Helvetica, sans-serif;">分享到朋友圈只有标题显示</span>    WeixinJSBridge.invoke('shareTimeline',{        "img_url": wimg,        "img_width": "200",        "img_height": "200",        "link": wurl,        "desc": wdesc,        "title": wtit    });}function shareWeibo() { <span style="font-family: Arial, Helvetica, sans-serif;">//</span><span style="font-family: Arial, Helvetica, sans-serif;">分享到微博只有内容显示</span>    WeixinJSBridge.invoke('shareWeibo',{        "content": wdesc,        "url": wurl,    });}// 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){        shareMsg();    });    // 分享到朋友圈    WeixinJSBridge.on('menu:share:timeline', function(argv){        shareQuan();    });    // 分享到微博    WeixinJSBridge.on('menu:share:weibo', function(argv){        shareWeibo();    });}, false);</script>
