javascript - 如何在水平滚动时固定左侧 div 并在垂直滚动时固定顶部(类似 Excel)？

Question

我想做一些类似 excel 的事情。垂直滚动时固定顶部标题，水平滚动时固定左侧“标题”。

这是我的带有嵌入样式和 CSS 的 HTML

Answer 1

试试这个:

CSS:

.HeaderRow {
position:fixed;//For vertical purposes
}

Javascript(JQUERY):

var posWas = $(window).scrollLeft();
$(window).bind('scroll', function(){
var posIs = $(window).scrollLeft();
if(posWas !== posIs){
//Scrolled Horizontal
$('.headerRow').css("position" , "relative");
$('.headerRow').css("left" , posIs );
$('.headerRow').css("position" , "fixed" );
posWas = posIs;//Save it for the Next Run
}
//Scrolled vertically keep as you are
});  

如果您想修复另一个类或 div，请在代码中进行更改。
