I need JavaScript or jQuery something to change text every few seconds... without the user doing anything.

欢迎"更改为Salmat datang"；3 秒后变为Namaste"等并循环返回.

"Welcome" changes to "Salmat datang" changes to "Namaste", etc. after 3 seconds and loops back.

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>
