也可以直接写：
<script>
function test(){
parent.oMxh.scrollBy(50,20)
}
</script>
<input type=button onclick="test()" value="Scroll it">
<iframe src="a.htm" id=oMxh height=100></iframe>
但必须保证iframe的内容大于100的高度
test.htm
================
<input type=button onclick="parent.oMxh.moveit()" value="Scroll it">
<iframe src="a.htm" id=oMxh height=100></iframe>a.htm
=======================
<script>
function moveit(){
window.scrollBy(20,20)
}
</script>

我感觉在 iframe 里边使用锚点更简单，你可以点击链接到你想去的任何地方！
