Question

我正在尝试将数组中的字符串作为句子输出，并且在单词之间输出用于分隔字符串的逗号，这很烦人。

let words = document.getElementById("Words");
let wordAr = ["This" , "is" , "a" , "test"];
let textIn = document.getElementById("Input");
let timer = 0;
let WPM = 0;
let text = document.getElementById("text");

words.innerHTML = wordAr.slice(0,4);

window.addEventListener("keydown", function(key){
    if(key.keyCode == 32){
        for (let i=0; i < wordAr.length; i++){
            WPM++;
        };
        console.log("test");
    };
});

您可以join()使用空格。

let wordAr = ["This" , "is" , "a" , "test"];
console.log(wordAr.join(' '))
