HTML DOM offsetHeight 属性


实例

获取<div> 元素的高度和宽度,包括填充和边框:

var elmnt = document.getElementById("myDIV");
var txt = "Height with padding and border: " + elmnt.offsetHeight + "px<br>";
txt += "Width with padding and border: " + elmnt.offsetWidth + "px";
亲自试一试 »

页面下方有更多实例。


定义和用法

offsetHeight 属性返回元素的可视高度(以像素为单位),包括填充、边框和滚动条,但不返回边距。

之所以指定"可视",是因为如果元素的内容高于元素的实际高度,此属性将只返回可见的高度(请参阅"更多示例")。

注释: 要理解这个属性,您必须理解CSS 框模型

提示: 此属性通常与offsetWidth 属性一起使用。

提示: 使用 clientHeightclientWidth 属性返回元素的可视高度和宽度,仅包括填充。

提示: 要向元素添加滚动条,请使用 CSSoverflow 属性。

该属性是只读的。

实例

此示例演示了 clientHeight/clientWidth 和 offsetHeight/offsetWidth 之间的差异:

var elmnt = document.getElementById("myDIV");
var txt = "";
txt += "Height with padding: " + elmnt.clientHeight + "px<br>";
txt += "Height with padding and border: " + elmnt.offsetHeight + "px<br>";
txt += "Width with padding: " + elmnt.clientWidth + "px<br>";
txt += "Width with padding and border: " + elmnt.offsetWidth + "px";

实例

此示例演示了在元素中添加滚动条时,clientHeight/clientWidth 和 offsetHeight/offsetWidth 之间的区别:

var elmnt = document.getElementById("myDIV");
var txt = "";
txt += "Height with padding: " + elmnt.clientHeight + "px<br>";
txt += "Height with padding, border and scrollbar: " + elmnt.offsetHeight + "px<br>";
txt += "Width with padding: " + elmnt.clientWidth + "px<br>";
txt += "Width with padding, border and scrollbar: " + elmnt.offsetWidth + "px";
