问题描述
我有这段代码，可以让任何人知道如何在2秒内更改此随机关键字.
Hi I have this code can any one know how to change this random keyword in 2 seconds.
function shuffle(a, b) {
return Math.random() > 0.5 ? -1 : 1;
}
var keywords = ["<div>1</div>", "<div>2</div>", "<div>3</div>", "<div>4</div>", "<div>5</div>", "<div>6</div>", "<div>7</div>", "<div>8</div>", "<div>9</div>", "<div>10</div>", "<div>11</div>", "<div>22</div>", "<div>44</div>", "<div>32</div>", "<div>46</div>"];
var randomKeywords = keywords.sort(shuffle);
function luckcricket() {
document.write(randomKeywords);
alert('laad');
}
luckcricket();
推荐答案
您可能是指window.setInterval(function,delay)
function shuffleKeywords() {
randomKeywords = randomKeywords.sort(shuffle);
}
window.setInterval(function(){shuffleKeywords()},2000);
您也可以使用window.setTimeout(function,delay). setTimeout将在2秒后启动一次.
You could also use window.setTimeout(function,delay). setTimeout will launch after 2 seconds once.
function shuffleKeywords() {
randomKeywords = randomKeywords.sort(shuffle);
}
window.setTimeout(function(){shuffleKeywords()},2000);
更新:
JS代码:
function shuffle(a,b) {
Math.random() > 0.5 ? -1 : 1;
}
var keyWord = ["<div>1</div>","<div>2</div>","<div>3</div>","<div>4</div>"];
window.setInterval(function() {
keyWord = keyWord.sort(shuffle);
// First line below will append divs to the document, Second line will replace it, use on of them
document.getElementById('appended').appendChild(document.createTextNode(keyWord));
document.getElementById('appended').innerHTML = keyWord;
}, 2000);
HTML代码:
<html>
<body>
<div id="appended"></div>
</body>
</html>
