//重定向

  var acceptedWebsites = ['www.cnn.com'，'www.nytimes.com'，'www.latimes.com'，'www.washingtonpost.com'，'www.nbcnews.com'， 'www.foxnews.com']; 
 var currentUrl = document.location.href; 
 var referrer = currentUrl.match（/：\ / \ /（。[^ /] +）/）[1]; 
  

//确保代码符合我的要求。只要链接显示大于-1的数字，网站扩展程序就可以正常工作
console.log（referrer）;
console.log（acceptedWebsites.indexOf（referrer））;

// var url = acceptedWebsites [Math.floor（Math.random（）* acceptedWebsites。长度）];
//document.location.href = url;

//图片源经过以下脚本函数
$（'img'）。 each（function（）{

//创建随机化

  var random = arrayImg [Math.floor（Math.random（）* arrayImg.length）]; 
 //获取当前数组并使用随机函数
（this）.attr 'src'，random）; 
 //消除延伸
 var theWidth = $（this）.width（）; 
 var theHeight = $（this）.height（）; 
 if（theWidth< theHeight）{
 $（this）.height（150）; 
} 
 else {
 $（this）.width（150）; 
} 
}）; 
  

// alert（转到以下任一网站：fox.com，nbc.com， nytimes.com，latimes.com或cnn.com）;

我在javascript中有这个数组。我想拥有它，以便用户可能会随机地自动重定向到数组中的其中一个链接。我不知道我是否可以在JavaScript中做到这一点。我使用这个扩展名，所以我不知道我是否可以使用PHP。

这些都是非常棒的答案，只是它们经常重定向。我想让它们只被重定向到数组中的一次，而不是经常重定向。

**编辑2：我添加了我的整个代码，因为有些东西会导致常量重定向，而不是一次。

**编辑3：我更新了我的代码。 console.log证明我的新变量可以工作并执行== - 1。

解决方案

从数组中获取一个随机URL并重定向？

$ b如何使用它们重定向？
$ b

  if（acceptedWebsites.indexOf（document.location.href）== -1）{
 var url = acceptedWebsites [Math.floor（Math .random（）* acceptedWebsites.length）]; 
 document.location.href = url; 
}

//Making sure the code does what I want it to. As long as the link shows a number greater than -1, then the site extension is working console.log(referrer); console.log(acceptedWebsites.indexOf(referrer));

// image source goes through the following script function $('img').each(function(){

var random = arrayImg[Math.floor(Math.random()*arrayImg.length)];
//Takes the current array and applies the source with the random function
$(this).attr('src', random);
//removing the stretch
 var theWidth = $(this).width();
            var theHeight = $(this).height();
            if (theWidth < theHeight) {
                $(this).height(150);
            }
            else {
                $(this).width(150);
            }
});

//alert ("Go to any of the follow websites: fox.com, nbc.com, nytimes.com, latimes.com, or cnn.com");

I have this array in javascript. I want to have it so that the user is automatically redirected to one of the links from the array, possibly randomly. I don't know if I can do this in javascript. I am using this for a chrome extension, so I don't know if I can use php.

These are fantastic answers, except they constantly redirect. I want it so that they are just redirected to one from the array once, not constantly redirect.

**Edit 2: I added my whole code because something is causing there to be a constant redirect instead of only once.

**Edit 3: I updated my code. The console.log proves that my new variables work and do ==-1. How can I use them to redirect?

解决方案

Get a random URL from the array, and redirect ?

if ( acceptedWebsites.indexOf(document.location.href) == -1 ) {
    var url = acceptedWebsites[Math.floor(Math.random()*acceptedWebsites.length)];
    document.location.href = url;
}
