如何用js得到div的高度
function adjustcolumnheight(){
var main col = window . document . getelementbyid(& # 39;主列& # 39;);
var left col = window . document . getelementbyid(& # 39;MainLeft & # 39);
var right col = window . document . getelementbyid(& # 39;MainRight & # 39);
var hMainCol = mainCol。偏高;
var hLeftCol = left col . offsetheight;
var hRightCol = right col . offsetheight;
var maxHeight = Math.max( hMainCol,Math.max(hLeftCol,hRightCol));
main col . style . height = max height
& # 39;px & # 39;
left col . style . height = max height
& # 39;px & # 39;
right col . style . height = max height
& # 39;px & # 39;
}上面的代码是获取3个DIV的高度,判断最高DIV的高度值,使另外两个较短DIV的高度等于最高的DIV。自己想清楚很简单。
