Javascript从警告框重定向

Question

您好我有一个使用javascript调用的警告框，我想在警报框中有人点击确定时重定向到users_signup页面我该怎么办呢？

alert("You need to sign in to be able to vote");
   redirect_to sign_up_url

Answer 1

if (confirm("You need to sign in to be able to vote")){
   // They have clicked OK
   window.location = 'http://website.com/sign_up_url';
}

或者，在弹出警告框后强制重定向：

alert("You need to sign in to be able to vote");
// The code execution won't proceed until they click OK
window.location = 'http://website.com/sign_up_url';
