问题10：获取当前页面宽度JS

var mleft=document.getElementById("mleft"); var h = document.documentElement.clientHeight; mleft.style.height=h-68+"px";

 

水平滚动条：<div style="width:100px;overflow-x:auto"></div> 垂直滚动条：<div style="height:300px;overflow-y:auto"></div> 水平加垂直：<div style="width:100px;height:300px;overflow-x:auto;overflow-y:auto"></div>
