微信分享到朋友圈需要设置图片链接标题描述，同理分享到微博一样的js，需要预加载这些js
<script>
var imgUrl = '';//图片地址
var lineLink = '';//链接地址
var shareTitle = '';//分享标题
var descContent = "";//描述内容
var appid = '';
function shareFriend() {
WeixinJSBridge.invoke('sendAppMessage',{
"appid": appid,
"img_url": imgUrl,
"img_width": "640",
"img_height": "640",
"link": lineLink,
"desc": descContent,
"title": shareTitle
}, function(res) {
_report('send_msg', res.err_msg);
})
}
function shareTimeline() {
WeixinJSBridge.invoke('shareTimeline',{
"img_url": imgUrl,
"img_width": "640",
"img_height": "640",
"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>
