Question

我试图建立一个链接，当用户点击它以随机更改网址到其中一个变种时。

$(".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;
})

问题已解决，谢谢。 By Scott Marcus

Answer 1

在代码的最后，您错误地调用了您的函数：randomLang();当它真的是：randomLangFunction()。我还删除了您的rand功能并将其合并到另一个功能中。

$(".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;
})
