[英]how to get the top left coordinates of the screen with javascript on firefox
I have a <div>
element with position: absolute
and z-index something big. 我有一个<div>
元素, position: absolute
和z-index大。 I would like to cover the entire screen with this div with javascript. 我想用javascript将此div覆盖整个屏幕。 This is what I do and it works: 这是我做的,并且有效:
document.getElementById('mydiv').style.top = 0;
document.getElementById('mydiv').style.left = 0;
document.getElementById('mydiv').style.width = '100%';
document.getElementById('mydiv').style.height = '100%';
However, when I scroll down with long webpages, this code displays my div at the top of the page, so the div renders above the region I currently view. 但是,当我向下滚动较长的网页时,此代码将div显示在页面顶部,因此div呈现在我当前查看的区域上方。 How can I change the top and left values so that my div always covers the active field I am viewing? 如何更改顶部和左侧的值,以便我的div始终覆盖我正在查看的活动字段?
I work on firefox 3.6.*. 我正在使用Firefox 3.6。*。
Thank you 谢谢
Change it to position: fixed
. 将其更改为position: fixed
。
Note that this won't work in IE6. 请注意,这在IE6中不起作用。
