Question

我的网页上有两张桌子并排。当鼠标悬停在第一桌或第二桌上的单元格上时（例如单元格（2,5）），我想要突出显示第一个表格的单元格（2,5）和第二个表格的第二个表格。 s单元格（2,5）同时。我已经用Css尝试了它，但我认为用Css做它是不可能的。

Answer 1

使用一些jQuery代码来获取魔力，请查看我的代码段

$('table td').hover(function(){
  // Highlight
  var curentEl = $(this);
  var outerEl = curentEl.closest('.outer');
  var col = $(this).parent().children().index($(this));
  var row = $(this).parent().parent().children().index($(this).parent());
  outerEl.find('table').each(function() {
    $(this).find('tr:eq('+ row +')' + ' ' + 'td:eq('+ col +')').addClass('hover');
  });
}, function() {
  //Removing Highlight when mouse out
  $(this).closest('.outer').find('.hover').removeClass('hover');
});
