切换case语句，窗口位置href为我的情况

Question

我希望在位置href中使用switch case语句来处理我的不同条件。我试图避免继续写if语句

if (/red/.test(self.location.href)){
   //do this red
 }

if (/blue/.test(self.location.href)){
   //do this blue
}

if (/yello/.test(self.location.href)){
  //do this yellow
}

Answer 1

var _url = window.location.href;
swith(true){
    case /red/.test(_url):
    //do red
    break;
    case /blue/.test(_url):
    //do blue
    break;
    case /yellow/.test(_url):
      // do yellow
    break;
 }
