DivCSS实例:让页脚保持在未满屏页面的底部
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;测试了一下,还可以,在IE6、IE7、FF等都没有问题!窗口缩小时也没有问题!
首先是JS脚本:
functiontest(){
varinfoHeight=document.getElementById("info").scrollHeight;
varbottomHeight=document.getElementById("bottom").scrollHeight;
varallHeight=document.documentElement.clientHeight;
varbottom=document.getElementById("bottom");
if((infoHeight+bottomHeight)allHeight){
bottom.style.position="absolute";
bottom.style.bottom=
}else{
bottom.style.position=
bottom.style.bottom=
}
setTimeout(function(){test();},10);
}
test();
查看运行效果:
