代码示例：（标识：event_onpageshow_dom）
<!DOCTYPE html>
<html>
<body>
<p>本例使用 HTML DOM 将 "onpageshow" 事件分配给 body 元素。</p>
<p><b>注释：</b>Internet Explorer 10 及更早版本不支持 onpageshow 事件。</p>
<h1 id="demo"></h1>
<script>
document.getElementsByTagName("BODY")[0].onpageshow = function() {myFunction()};
function myFunction() {
document.getElementById("demo").innerHTML = "Welcome To My Homepage!";
};
/* This is equivalent to assigning the event to the window object:
window.onpageshow = function() {
document.getElementById("demo").innerHTML = "Welcome To My Homepage!";
};
*/
</script>
</body>
</html>
