<html> <head> <title> </title> </head> <body> <script> function f() { window.setTimeout("populate()", 2000); } function populate() { document.f1.t1.value = "populated"; document.getElementById("id1").innerHTML = "<div id ='id2'>id 2</div>" } </script> <form name="f1"> <input type="text" name="t1"> <input type="button" value="Click me" onclick="f()"> <div id="id1"> </div> </form> </body> </html>
等待時間為兩秒 如果等待時間改為1或者找不到元素則丟擲異常
