How to Move Highlighted Row using Up/Down?

问题

I've translated the provided content into Chinese:

"我一直在尝试创建一个可以使用上/下箭头键导航到其他行的表格。但是当使用上/下箭头键时，它只能工作一次。之后，高亮显示的行不再移动，输入也无法填充。

你知道我的代码有什么问题吗？

谢谢。

var table = $('#transaksiKasir tr:last');
table.addClass('bg-slate-700 text-white');

$('body').on('keydown', function(e) {
  e.preventDefault();
  
  if (e.keyCode == 40) {
    table.removeClass('bg-slate-700 text-white');
    table.next().addClass('bg-slate-700 text-white')
  } else if (e.keyCode == 38) {
    table.removeClass('bg-slate-700 text-white');
    table.prev().addClass('bg-slate-700 text-white');
  }
});

<table class="items-center w-full align-top border-gray-200 text-slate-500 mb-4" id="transaksiKasir">
  <!-- 表格的内容... -->
</table>

以上是您提供的代码和问题的翻译。"

英文:

I've been trying to make table that can navigate to other rows using arrow key up/down. But when using up/down it only works once. After that the highlighted row is not moving and the input cannot be filled.

Do you know what's wrong with my code?

Thanks.

var table = $(&#39;#transaksiKasir tr:last&#39;);
table.addClass(&#39;bg-slate-700 text-white&#39;);

$(&#39;body&#39;).on(&#39;keydown&#39;, function(e) {
  e.preventDefault();
  
  if (e.keyCode == 40) {
    table.removeClass(&#39;bg-slate-700 text-white&#39;);
    table.next().addClass(&#39;bg-slate-700 text-white&#39;)
  } else if (e.keyCode == 38) {
    table.removeClass(&#39;bg-slate-700 text-white&#39;);
    table.prev().addClass(&#39;bg-slate-700 text-white&#39;);

得分: 1

你定义了最后一行将被突出显示，并且当你将突出显示移到另一行时，你的最后一行不再突出显示，根据他的说法，你没有移动突出显示的起点。

这是有效的解决方案：

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->
// Your initial highlighting the last row
var table = $('#transaksiKasir tr:last');
table.addClass('bg-slate-700 text-white');

$('body').on('keydown', function (e){
     e.preventDefault();

     // Take this values for every arrow key press
     if(e.keyCode == 40 || e.keyCode == 38){
        var table = $('#transaksiKasir tbody tr');
        var table_row = $('#transaksiKasir tr.text-white');
     }
     // Down
     if(e.keyCode == 40){
         // Stop at the last row
         if(table_row.index() == table.length - 1) {
             return false;
         }
         
         table_row.removeClass('bg-slate-700 text-white');
         table_row.next().addClass('bg-slate-700 text-white')
     }
     // Up
     else if(e.keyCode == 38){
         // Stop at the first row
         if(table_row.index() == 0) {
             return false;
         }
         
         table_row.removeClass('bg-slate-700 text-white');

英文:

You defined that last row will be highlighted row, and when you move highlight to another row your last row is no more highlighted, and according to him you don't have starting point to move highlight again.

This is working solution:

           // Your initial highlighting the last row
var table = $(&#39;#transaksiKasir tr:last&#39;);
table.addClass(&#39;bg-slate-700 text-white&#39;);
$(&#39;body&#39;).on(&#39;keydown&#39;, function (e){
e.preventDefault();
// Take this values for every arrow key press
if(e.keyCode == 40 || e.keyCode == 38){
var table = $(&#39;#transaksiKasir tbody tr&#39;);
var table_row = $(&#39;#transaksiKasir tr.text-white&#39;);
}
// Down
if(e.keyCode == 40){
// Stop at the last row
if(table_row.index() == table.length - 1) {
return false;
}
table_row.removeClass(&#39;bg-slate-700 text-white&#39;);
table_row.next().addClass(&#39;bg-slate-700 text-white&#39;)
}
// Up
else if(e.keyCode == 38){
// Stop at the first row
if(table_row.index() == 0) {
return false;
}
table_row.removeClass(&#39;bg-slate-700 text-white&#39;);
table_row.prev().addClass(&#39;bg-slate-700 text-white&#39;);
}
});
