微信分享代码示例
    {notempty name="wx_config"}
    {script}
    wx.config({$wx_config|raw});
    wx.ready(function () {
        var shareData = {$share_data|raw};
        if(wx.onMenuShareAppMessage){ //微信文档中提到这两个接口即将弃用，故判断
            wx.onMenuShareAppMessage(shareData);//1.0 分享到朋友
            wx.onMenuShareTimeline(shareData);//1.0分享到朋友圈
        }else{
            wx.updateAppMessageShareData(shareData);//1.4 分享到朋友
            wx.updateTimelineShareData(shareData);//1.4分享到朋友圈
        }
