<p>该实例演示了如何使用 HTML DOM 向 body 元素添加 "onpageshow" 事件。</p>
<h1 id="demo"></h1>
<script>
document.getElementsByTagName("BODY")[0].onpageshow = function() {myFunction()};
function myFunction() {
  document.getElementById("demo").innerHTML = "欢迎来到我的主页!";
};
/* 这个与在 window 对象中添加事件相同:
window.onpageshow = function() {
    document.getElementById("demo").innerHTML = "欢迎来到我的主页!";
};
*/
