HTML DOM clientLeft 属性


实例

获取<div> 元素的上边框和左边框的宽度:

页面下方有更多实例。


定义和用法

clientLeft 属性返回元素左边框的宽度(以像素为单位)。

此属性不包括元素的左填充或左边框。

提示: 还可以使用style.borderLeftWidth 属性返回元素左边框的宽度。

注释: 对于Windows上的Chrome、Firefox和Opera,如果元素有一个scrollbar 滚动条(由 CSS overflow 属性设置),并且该元素的文本方向是从右向左(由 CSS direction 属性设置),则该属性包括垂直滚动条的宽度以及左边框宽度。然而,在IE中,它返回 "0"。在Mac OS上,使用Safari、Chrome、Firefox 或 Opera,它只返回左边框宽度。

提示: 要返回元素上边框的宽度,请使用 clientTop 属性。

该属性是只读的。
