问题描述
我一直在Internet上四处浏览，即使我确定这是一个非常简单的修复程序，也找不到任何有关如何解决此问题的帖子.
I've been looking around on the internet and I cant find any posts that cover how to fix this even though I am certain it is a very simple fix.
基本上，我有一个带有数字值的数组，我想过滤掉大于10的任何数字并将它们添加到另一个数组中.到目前为止，这是我得到的，但是我得到的是第一个数组中的所有数字.
Basically I have an array with number values in it and I want to filter out any numbers that are greater than 10 and add them into another array. Here's what I have so far but what I am getting is all of the numbers from the first array.
<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>
<button type="button" onclick="alert(output)">Click Me!</button>
<script>
var input = new Array(9,3,4.3,24,54,8,19,23,46,87,3.14);
var output = new Array();
var length = 1;
for (var i = 0; i < input.length; i += length) {
output.push(input.slice(i, i + length).join(" "));
}
</script>
</body>
</html>
推荐答案
function predicate(x) { return x > 10 }
var output = input.filter(predicate);
input = input.filter(function(x) { return !predicate(x) })
使用ES6箭头功能看起来更干净:
Looks even cleaner with ES6 arrow functions:
var predicate = (x) => x > 10;
var output = input.filter(predicate);
input = input.filter(x => !predicate(x));
