點擊更改網址到隨機增值服務

Question

我正在嘗試建立一個鏈接，當用戶點擊它將網址隨機更改爲增值服務中的一個。

$(".link").click(function(){ 

    var safeLangs = ['en','al','de','fr','gr']; 
    var rand = function() { 
     return Math.floor(Math.random()*6); 
    }; 
    var randomLangFunction = function() { 
     var randomLang = safeLangs[rand()]; 
     return randomLang; 
    }; 

    url = "?lang=" + randomLang(); 
    window.location = url; 
}) 

問題已修復，謝謝。 By Scott Marcus

Answer 1

在代碼結尾處，您錯誤地調用了您的函數：randomLang();實際上是：randomLangFunction()。我也刪除了你的rand函數，並將它合併到另一個函數中。

$(".link").click(function(){ 
 

 
    var safeLangs = ['en','al','de','fr','gr']; 
 
    
 
    var randomLangFunction = function() { 
 
     // No need to make a separate function for the random since 
 
     // this function is part of that process. Also, don't hard 
 
     // code "6" as the random multiplier as that will need to 
 
     // change if you add more languages. Just get the length 
 
     // of the languages array: 
 
     return safeLangs[Math.floor(Math.random()*safeLangs.length)]; 
 
    }; 
 

 
    url = "?lang=" + randomLangFunction(); 
 
    console.log(url); 
 

 
    // Commented only for example to work: 
 
    // window.location = url; 
 
})
