javascript - td的水平和垂直滚动，th应该是固定的

Question

“th”值应该是固定的，“td”值应该滚动，如果“th”高度超过 100px，那么“then”也应该随着相应的“td”滚动。“th”和“td”的数量是动态的，请帮助我。

Answer 1

你可以css这样写：

.selectionContainer td
{
    width:100px;overflow:auto;
}
.selectionContainer th
{
    width:100px;overflow:auto;height:100px;
}

Answer 2

您可以将 scrollTop() 和 scrollLeft() 与 Jquery 一起使用；

$(yourTDdiv).scroll(function () { verthandlescrollbars(th, tdDiv, thDiv); });
$(yourTDdiv).scroll(function () { horihandlescrollbars(th, tdDiv, thDiv); });

function verthandlescrollbars(th ,thDiv, tdDiv){  
     if($(th).height() > 100){

        $(thDiv).scrollLeft($(tdDiv).scrollLeft());

      }
 }

function horihandlescrollbars(th, tdDiv, thDiv){
   //the same as verthandlescrollbars function!
   //$(thDiv).scrollTop 
}

这应该是一个伪代码。
