在JavaScript中按字符串长度过滤数组 [英] Filter array by string length in javascript

问题描述

我真的是javascript的初学者

I'm a really beginner in javascript

我有一个包含的数组

array_1 = ["the","quick","brown","fox","jumped","over","the","lazy","dog"]

我想要另一个数组，但只包含长度> 3的单词

And I want another array but only with words that have length > 3

array_cleaned = ["quick","brown","jumped","lazy"]

当前实施方式:

array_1 = ["the","quick","brown","fox","jumped","over","the","lazy","dog"]

array_clean = [];
for(var i=0; i<array_1.length; i++){
    if(array_1[i].length > 3) 
        array_clean.push(array_1[i]);
}

document.write(array_clean)

但是我正在寻找一种实际过滤它的方法.有什么想法吗?

But I'm looking for a way to actually filter it. Any ideas?

推荐答案

您可以使用

You can use filter method:

var array_1 = ["the","quick","brown","fox","jumped","over","the","lazy","dog"];
var array_cleaned = array_1.filter( function( element ) {
  return element.length > 3;
});
console.log(array_cleaned); //["quick", "brown", "jumped", "over", "lazy"]
