4. 全页面无法点击

//播放设置
let setting = storage('setting');
options.interval = setting && setting.auto_speed ? setting.auto_speed*1000 : 3000;
//VIEWER
pics.html(tpl).viewer(options).find('img').lazyload();
if (setting) {
if (setting.auto_show) {
pics.viewer('show',true);
if (setting.auto_play) pics.viewer('play');
} else if (setting.auto_play) {
pics.viewer('show',true).viewer('play');
}
}

You should call the hide method with its first parameter set to true too:

viewer.show(true);
viewer.hide(true);
