Javascript從警報框中重定向

Question

嗨我有一個警告框，使用javascript調用時，我想重定向到users_signup頁面，當有人單擊確定警告框時，我該如何做到這一點？

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'; 
} 

或者強制重定向的警告框已經彈出後：

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';
