Question

这是轮盘赌游戏，您可以获得"coin coin-ct"或"coin coin-t"或"coin coin-bonus"。如果可能，我如何知道行重复"coin coin-ct"变量的3或4次完整时间？我是新手，对不起误会。

作为：

<div class="icon-box">
  <div class="coin coin-ct"></div>
  <div class="round">#2721574 - 13</div>
</div>
<div class="icon-box">
  <div class="coin coin-ct"></div>
  <div class="round">#2721573 - 11</div>
</div>
<div class="icon-box">
  <div class="coin coin-ct"></div>
  <div class="round">#2721572 - 10</div>
</div>

完整代码示例（现实生活中的更多内容）：

<div class="icon-box">
  <div class="coin coin-ct"></div>
  <div class="round">#2721574 - 13</div>
</div>
<div class="icon-box">
  <div class="coin coin-ct"></div>
  <div class="round">#2721573 - 11</div>
</div>
<div class="icon-box">
  <div class="coin coin-bonus"></div>
  <div class="round">#2721572 - 0</div>
</div>
<div class="icon-box">
  <div class="coin coin-t"></div>
  <div class="round">#2721571 - 6</div>
</div>
<div class="icon-box">
  <div class="coin coin-ct"></div>
  <div class="round">#2721570 - 9</div>
</div>

Answer 1

对每一行使用JQuery选择器，选择其类为coin coin-ct的子项。

<强> $（ “行”）

一个类选择器，它获取类row的所有元素。（class="row"）

<强> $（ “行”）。每个（函数（ITM）{}）

所有元素的迭代器都有类row。

<强> $（本）。儿童（ “div.icon盒”）

用于选择div所选元素的所有子元素并具有类icon-box

如下所示：

$(".row").each(function(itm) {
  $(this)
    .children("div.icon-box")
    .each(function(obj) {
      console.log($(this).children(".coin.coin-ct").length)
    });
  console.log("-----------------------------");
});
