JavaScriptでclientHeightとoffset Height、scrollHeightの違い
3097 ワード
私達はJavaScriptを勉強する時、いつも各種の高度を獲得して、幅の問題に出会って、毎回使う時ネット上で探して、今日私はいくつかのjsの中の高度の幅の方法を整理してみんなにあげます.
1.lient Width/client Height
body:
1.lient Width/client Height
/ , /
padding
2.offset Height/offset Width IE6,IE7,IE8 FF, Chrome , offsetHeight = clientHeight + + 。
3.scrollHeight/scrollwidthscrollHeight padding 。 , 。
:scrollHeight = topPadding + bottomPadding + margix box 。
Chromeで:body:
clientHeight = body.padding + body.height(css );
offsetHeight = body.clientHeight + body.border;
scrollHeight = body.padding + ( height ), documentElement.clientHeight
documentElement:clientHeight = window – 。
offsetHeight = body.offsetHeight + body.margin;
scrollHeight = ( body height ), documentElement.offsetHeight
元素上:offsetHeight = padding + border + height
clientHeight = padding + height - scrollbar.width
scrollHeight = padding+content ( )
