自动单元格填充

  • 772

有一个像素字段和一个用于选择改变颜色的像素的代码：

$(".pixel").click(function() {
  $(this).toggleClass("white");
  $(this).toggleClass("black");
})
var delta;
var isCall = false;
if (!isCall) {
  var zoom = 1;
  isCall = true;
}
#art {
  width: 101px;
  height: 101px;
  display: table;
  border-spacing: 1px;
  background-color: #d8d8d8;
}

.row {
  display: table-row;
}

.pixel {
  display: table-cell;
}

.black {
  background-color: black;
}

.white {
  background-color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="art">
  <div class="row">
    <div class="pixel white" id="1-1"></div>
    <div class="pixel white" id="1-2"></div>
    <div class="pixel white" id="1-3"></div>
    <div class="pixel white" id="1-4"></div>
    <div class="pixel white" id="1-5"></div>
  </div>
  <div class="row">
    <div class="pixel white" id="2-1"></div>
    <div class="pixel white" id="2-2"></div>
    <div class="pixel white" id="2-3"></div>
    <div class="pixel white" id="2-4"></div>
    <div class="pixel white" id="2-5"></div>
  </div>
  <div class="row">
    <div class="pixel white" id="3-1"></div>
    <div class="pixel white" id="3-2"></div>
    <div class="pixel white" id="3-3"></div>
    <div class="pixel white" id="3-4"></div>
    <div class="pixel white" id="3-5"></div>
  </div>
  <div class="row">
    <div class="pixel white" id="4-1"></div>
    <div class="pixel white" id="4-2"></div>
    <div class="pixel white" id="4-3"></div>
    <div class="pixel white" id="4-4"></div>
    <div class="pixel white" id="4-5"></div>
  </div>
  <div class="row">
    <div class="pixel white" id="5-1"></div>
    <div class="pixel white" id="5-2"></div>
    <div class="pixel white" id="5-3"></div>
    <div class="pixel white" id="5-4"></div>
    <div class="pixel white" id="5-5"></div>
  </div>
</div>

但是需要自动填充整个字段，假设我单击某个单元格，随机相邻的单元格会稍微延迟填充（就像多米诺骨牌向各个方向倒下）等等，直到整个字段都被填充。这甚至可以实施吗？我被暗示在KAMI游戏中有类似的算法，但我还没有弄清楚如何做到这一点，所以我希望你的建议。
