script
var $goDownload = $('#goDownload'),
$maskWrap = $('#maskWrap'),
$closeNote = $('#closeNote');
var is_weixin = (function(){return navigator.userAgent.toLowerCase().indexOf('micromessenger') !== -1})();
if (is_weixin) {
$goDownload.on('click',function(e){
$('#goDownload').attr('href','javascript:void(0);');
$maskWrap.css('display','block')
})
$closeNote.on('click',function(){
$maskWrap.css('display','none');
})
}
//主要原理判斷網頁是否在微信中開啟，如果在微信中開啟則禁止連線。
