点击更改网址到随机增值服务

Question

我正在尝试建立一个链接，当用户点击它将网址随机更改为增值服务中的一个。

$(".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; 
}) 

问题已修复，谢谢。 By Scott Marcus

在代码结尾处，您错误地调用了您的函数：randomLang();实际上是：randomLangFunction()。我也删除了你的rand函数，并将它合并到另一个函数中。

$(".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; 
 
})
