在手机UI里,想布局三个DIV,TOP为上部,FOOTER为下部,op_float_bar在TOP里面的底部,请问这个DIV的高度如何设置?
#top { width:100%; height:???;}
楼主不妨学习学习jquery-mobile???
若楼主执意手动设定,可以采用jq
<!DOCTYPE html><html><head><script src="http://www.w3school.com.cn/jquery/jquery-1.11.1.min.js"></script><script type="text/javascript">$(function() { //获取页面的可视区域高度和宽度 var wHeight=document.documentElement.clientHeight; var footerH= $("#footer").height(); var newH=wHeight-footerH+"px"; //alert(footerH.height()); $("#top_float_bar").css("height",newH);}); </script></head><body><div id="top" style="background:yellow;">123</div><div id="footer" style="height:300px;width:500px;background:red;"></div></body></html>
抱歉,,修改一下,,,赋值的时候不用加px
