如何使用JavaScript創建多個隨機段落元素？

Question

我正在嘗試使用此數組中的值創建帶有隨機文本的多個段落：

var values = ["Carl","Maria","Joseph","Tatiane","Dayanne"];

但老實說，我不知道該怎么做。 這是我的代碼...

var paragraph = document.createElement("p");
paragraph.innerText = "random string";
document.body.appendChild(paragraph);

我需要創建35個段落...

Answer 1

innerText是IE引入的古怪的非標准屬性。 強烈建議改用標准，更快，更可靠的textContent代替-請參見http://perfectionkills.com/the-poor-misunderstood-innerText

您可以使用arr[Math.floor(Math.random() * arr.length)]從數組中獲取隨機元素：

 const words = ["Carl","Maria","Joseph","Tatiane","Dayanne"]; Array.from({ length: 35 }) .forEach(() => { const randomText = words[Math.floor(Math.random() * words.length)]; document.body .appendChild(document.createElement("p")) .textContent = randomText; }); 

Answer 2

<script>
    var values = ["Carl", "Maria", "Joseph", "Tatiane", "Dayanne"];
    var total = 35;

    for (count = 1; count <= total; count++) {
        // Get random index within the array bounds
        var randomIndex = Math.floor(Math.random() * values.length);

        // Get value in the array that corresponds to the random index.
        var value = values[randomIndex];

        // Create the <p> tag.
        var p = document.createElement('p');
        p.innerText = value;
        document.body.appendChild(p);
    }
</script>
