分享请帮忙
页面a上有一字符串b="dsfdf",a里有iframe,当iframe跳转时，b发生变化，我想实现这样一个功能：当按浏览器的后退键返回a时,b变回原值。
谢谢！

<span id="sp1" name="sp1">adfadsf</span>
<iframe name="ifr1" name="ifr1" src="http://www.163.com"></iframe>
<button onclick="document.all.ifr1.src='http://www.sohu.com';">改变iframe1中的地址</iframe>
<script>
<!--
function chgifr() {
document.all.sp1.innerText = document.all.ifr1.src;
}
window.setInterval("chgifr()",1000)

------------------------------------------------------
<html>
<body onload="parent.mySpan.innerHTML='asdfsadfsadfsadf'">
aaaaaaaaaaaaaaaa
<a href='if_b.html'>跳转</a>
</body>
</html>
if_b.html
---------------------------------------------------------

<body onload="parent.mySpan.innerHTML='hahahahahahahahahah'">
bbbbbbbbbbbbbb
<button onclick="history.go(-1)">返回</button>
