Question

这是此question的扩展。

我们得到了类似于以下结构的结构，具体取决于类score的元素的值，我们添加了一个类win或lose。

<div class="war">
  <div class="team">
    <span class="score">8</span>
  </div>
  <div class="team">
    <span class="score">5</span>
  </div>
</div>
<div class="war">
  <div class="team">
    <span class="score">12</span>
  </div>
  <div class="team">
    <span class="score">25</span>
  </div>
</div>
<div class="war">
  <div class="team">
    <span class="score">57</span>
  </div>
  <div class="team">
    <span class="score">57</span>
  </div>
</div>

用户Rory McCrossan提供了有效的解决方案https://stackoverflow.com/a/52757164/4236048

document.querySelectorAll('.war').forEach(function(war) {
  var scores = Array.from(war.getElementsByClassName("score"));
  var winIndex = scores.reduce((iMax, x, i, arr) => parseInt(x.innerText, 10) > parseInt(arr[iMax].innerText, 10) ? i : iMax, 0);      
  scores.forEach((score, i) => score.classList.add(winIndex == i ? 'win' : 'lose'));
});

但是我没有考虑平局的情况，其解决方案不再可行。

有没有想到在这种新情况下逻辑如何？ .win / .lose / .draw

预先感谢

比较WebMvConfigurer项内的得分并将类别应用于.war项

.score

function applyScoreClass() {
  $('.war').each(function(index, elem) {
    var $elem = $(elem);
    var warScores = [];
    $elem.find('.score').each(function(i,el) {
       var txt = $(el).text();
       var num = (txt && txt.length > 0) ? parseInt(txt) : null;
       if (num !== null) {
           warScores.push({
               elem: $(el),
               score: num
           });
       }
    });
    if (warScores.length === 2) {
       if (warScores[0].score > warScores[1].score) {
           warScores[0].elem.addClass('win');
           warScores[1].elem.addClass('lose');
       } else if (warScores[0].score === warScores[1].score) {
           warScores[0].elem.addClass('draw');
           warScores[1].elem.addClass('draw');
       } else if (warScores[0].score < warScores[1].score) {
           warScores[1].elem.addClass('win');
           warScores[0].elem.addClass('lose');
       }
    }
  });
}

applyScoreClass();

.war {
  border: 1px solid #d8d8d8;
}
.win {
  color: green;
}
.draw {
  color: orange;
}
.lose {
  color: red;
}

为HTML div / span定义ID值内部循环得分数组声明

devtools.panels

根据子DOM元素的值将不同的类应用于子DOM元素
