让一行页脚保持在底部
2008-03-17所谓保持在底部就是: 在内容不超过一屏的情况下, 当浏览器窗口变小那行页脚文字会跟着向上浮动但还是保持在底部。当内容多出一屏时,他显示在网页的最下边,而不是窗口的最下边;
测了一下,还可以,在IE6、IE7、FIREOFX等都没有问题! 窗口缩小时也没有问题!
[pre name="code" class="html"]<script language="JavaScript" type="text/javascript">
function test(){
var infoHeight = document.getElementById("info").scrollHeight;
var bottomHeight = document.getElementById("bottom").scrollHeight;
var allHeight = document.documentElement.clientHeight;
var bottom = document.getElementById("bottom");
if((infoHeight + bottomHeight) < allHeight){
bottom.style.position = "absolute";
bottom.style.bottom = "0";
}else{
bottom.style.position = "";
bottom.style.bottom = "";
}
setTimeout(function(){test();},10);
}
test();
</script>/code]
