JavaScript获取和设置div的高度和宽度,并且兼容任何浏览器?看代码:
<div id="div1" style="height:500px;width:500px;"></div>
<div id="div2" style="height:50px;width:50px;"></div>
获取div1的宽高度:
alert(document.getElementById("div1").offsetHeight); //兼容FF、IE等
alert(document.getElementById("div1").offsetWidth); //兼容FF、IE等
设置div1的宽高度为div2的宽高度:
document.getElementById("div1").style.height=document.getElementById("div2").offsetHeight; //仅IE
document.getElementById("div1").style.height=document.getElementById("div2").offsetHeight+ "px"; //兼容FF、IE等
document.getElementById("div1").style.width=document.getElementById("div2").offsetWidth; //仅IE
document.getElementById("div1").style.width=document.getElementById("div2").offsetWidth+ "px"; //兼容FF、IE等
复制代码代码如下:
<div id="div1" style="height:500px;width:500px;"></div>
<div id="div2" style="height:50px;width:50px;"></div>
