1.将以下代码加到head头里
<script>
window.imgUrl = "http://app55.vliang.com/img/share1.jpg";
(function(){
//外挂接口
var c = window.P_WX_C = window.P_WX_C || {};
//外挂接口事件
var d = window.P_WX_D = window.P_WX_D || {};
var onBridgeReady = function (){
WeixinJSBridge.call('hideToolbar');
var
appId = '',
link = "http://app55.vliang.com/home?wxid=<?=$_SESSION['wxid']?>&isshare=1",
title = htmlDecode("玩极限科考，找回高中背诵古文的被虐感！还有更丧心病狂的隐藏诗词关。来答题涨涨知识吧"),
desc = htmlDecode("玩极限科考，找回高中背诵古文的被虐感！还有更丧心病狂的隐藏诗词关。来答题涨涨知识吧。"),
fakeid = "",
desc = desc || link;
c.shareAppMessage = function(){
WeixinJSBridge.invoke('sendAppMessage',{
"appid" : appId,
"img_url" : window.imgUrl,
"img_width" : "640",
"img_height" : "640",
"link" : link,
"desc" : desc,
"title" : title
}, function(res){
});
};
c.shareWeibo = function(){
WeixinJSBridge.invoke('shareWeibo',{
"content" : title +link,
"url" : link
}, function(res){
});
};
c.shareTimeline = function(){
WeixinJSBridge.invoke('shareTimeline',{
"img_url" : window.imgUrl,
"img_width" : "640",
"img_height" : "640",
"link" : link,
"desc" : desc,
"title" : title
}, function(res){
});
};
WeixinJSBridge.on('menu:share:appmessage', function(argv){
title=htmlDecode("搜狗输入法");
c.shareAppMessage();
});
WeixinJSBridge.on('menu:share:timeline', function(argv){
title = htmlDecode("玩极限科考，找回高中背诵古文的被虐感！还有更丧心病狂的隐藏诗词关。来答题涨涨知识吧"),
c.shareTimeline();
});
var weiboContent = '';
WeixinJSBridge.on('menu:share:weibo', function(argv){
c.shareWeibo();
});
};
if(document.addEventListener){
document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
} else if(document.attachEvent){
document.attachEvent('WeixinJSBridgeReady' , onBridgeReady);
document.attachEvent('onWeixinJSBridgeReady' , onBridgeReady);
}
var imgs = $('.page img'),
imgsSrc = [],
minWidth = 0;
imgs.each(function(){
var jqthis = $(this),
src = jqthis.attr('data-src') || jqthis.attr('src');
if(jqthis.width() >= minWidth && src){
imgsSrc.push(src);
jqthis.on('click', function() {
reviewImage(src);
});
}
});
function reviewImage(src) {
if (typeof window.WeixinJSBridge != 'undefined') {
WeixinJSBridge.invoke('imagePreview', {
'current' : src,
'urls' : imgsSrc
});
}
}
}
)();
</script>
2.更改window.imgUrl的值（图片地址）
3.更改link,title,desc这些参数
