javascript - 在jquery中使用setTimeout()

Question

我对 Javascript 并不陌生，但后来我意识到我不知道如何使用 setTimeout() .

我已经尝试过这个:

$(document).ready(function(){

  setTimeout('changeit()',1000); // I have also tried setTimeout('changeit',1000);
  // var t = setTimeout('changeit()',1000); <--- tried also something like this.

  // changeit(); <-- works when i do this.

  function changeit(){
    $('#hello').html('Hello World - this was inserted using jQuery');
    // #hello is <p id="hello">Hello World</p>
  }
})

谁能帮我解决这个问题吗？

传递对 changeit 函数的引用，而不是 JavaScript 代码字符串。

$(document).ready(function() {
    setTimeout(changeit, 1000);
    function changeit() {
        $("#hello").html("Hello world - this was inserted using jQuery.");
    }
});
