Javascript 函数用于返回数组中长度超过定义数量的字符串

Question

我正在尝试编写一个函数，该函数接受一个字符串数组和一个数字，该数字返回数组中长度比定义的数字长的字符串。

下面是我开始使用的代码:

var words = ["Harold", "hen", "asdasda"];

var i = 5
words.sort(function filterLongWords(x , i){
    if (words[x].length > i){
        return words[x];
    }
    else {
        console.log("You have no words longer than the number " + i + ".");
    }
}); 

谢谢!

你可以使用Array.filter和Array.length来做你想做的事情

var longWords = words.filter(function(str) { return str.length > i; });
if (longWords.length == 0) {
  console.log("You have no words longer than the number " + i + ".");
}
