推荐答案
正如其他人所说,setInterval
是你的朋友:
As others have said, setInterval
is your friend:
var text = ["Welcome", "Hi", "Sup dude"];
var counter = 0;
var elem = document.getElementById("changeText");
var inst = setInterval(change, 1000);
function change() {
elem.innerHTML = text[counter];
counter++;
if (counter >= text.length) {
counter = 0;
// clearInterval(inst); // uncomment this if you want to stop refreshing after one cycle
}
}
<div id="changeText"></div>
