为js添加多个结果if语句

Question

使用OneSignal sdk设置几个结果。基本上，我希望网站仅向订阅了我的通知的用户展示某些内容。从他们的教程部分复制了一段代码。一切工作正常，如果只需要一个动作。一旦我添加另一个，我就休息了。

下面是一段代码

OneSignal.isPushNotificationsEnabled(function(isEnabled) { 
    if (isEnabled) 
     document.getElementsByClassName('testsig')[0].style.display = 'block'; 
     //as soon as I add following line, it stops working 
     document.getElementsByClassName('testhide')[0].style.display = 'none'; 
    else 
     console.log("Push notifications are not enabled yet.");  
    }); 

Answer 1

if条件包含multiple statements.So需要关闭{}条件将被执行后，properly.Otherwise只有一条语句。

OneSignal.isPushNotificationsEnabled(function(isEnabled) { 
    if (isEnabled) { 
     document.getElementsByClassName('testsig')[0].style.display = 'block'; 
     //as soon as I add following line, it stops working 
     document.getElementsByClassName('testhide')[0].style.display = 'none'; 
      } 
    else 
     console.log("Push notifications are not enabled yet.");  
    });
