如何在javascript中生成数字/字符序列？ [英] How to generate sequence of numbers/chars in javascript?

问题描述

有没有办法在javascript中生成字符或数字序列？

Is there a way to generate sequence of characters or numbers in javascript?

例如，我想创建包含8个1的数组。我可以用for循环来做，但想知道是否有可以为我做的jQuery库或javascript函数？

For example, I want to create array that contains eight 1s. I can do it with for loop, but wondering whether there is a jQuery library or javascript function that can do it for me?

推荐答案

对于您的示例，您可以创建自己的可重用函数：

You can make your own re-usable function I suppose, for your example:

function makeArray(count, content) {
   var result = [];
   if(typeof content == "function") {
      for(var i = 0; i < count; i++) {
         result.push(content(i));
      }
   } else {
      for(var i = 0; i < count; i++) {
         result.push(content);
      }
   }
   return result;
}

然后你可以做以下任何一种：

Then you could do either of these:

var myArray = makeArray(8, 1);
//or something more complex, for example:
var myArray = makeArray(8, function(i) { return i * 3; });

你可以在这里尝试一下，注意上面的例子根本不依赖于jQuery，所以你可以不用它。你只是没有从图书馆获得任何东西：）

You can give it a try here, note the above example doesn't rely on jQuery at all so you can use it without. You just don't gain anything from the library for something like this :)
