字符串
下面是HTML的外观

的图片。
我想找到Tennis和Football之间的最高高度，然后将该最高高度设置为Tennis和Football的高度。
同样，我想找到Basketball和Swimming之间的最高高度，然后将该最高高度设置为Basketball和Swimming的高度。
我知道如何使用Math.max找到最大高度。但如何找到每对两个div之间的最高高度？
我所尝试的：

('.TwoColumnUnit').each(function() {
  var pairs = [$(this).find('.TwoColumnUnit_Left'), $(this).find('.TwoColumnUnit_Right')];
  pairs.forEach(function(pair) {
      if (pair.length > 0) {
          var boxes = pair.find('.newsLetterDiv > div');
          var maxHeight = 0;
          boxes.each(function() {
              $(this).css('height', '');
              maxHeight = Math.max(maxHeight, $(this).height());
          });
          boxes.css('height', maxHeight + 'px');
      }
  });
});

型
这段代码的问题是，它在所有4个div之间找到最高的高度，然后将最高的高度值作为所有4个项目的高度。
但是我怎样才能找到第一个左格和右格之间的最高高度，然后在第二个左格和右格之间？
