我一直致力于将飞镖图像（646px X 646px）划分为多个部分。首先，我在此图像上有每个切片的弧度信息（0.314弧度（360度/ 20切片= 18度）），飞镖图像中心的精确x和y值，现在是包含开始和结束的查找表每个切片的弧度以及得分 - 即得分20，开始0，结束0.314。有没有人有任何关于如何检查鼠标点击/按键事件的提示，关于我选择的部分？也就是说，如果我选择20片，董事会将如何知道？

boardScores = [20, 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12, 5];

    for(var i = 0; i < boardScores.length; i++)
            {
                var id="SCORE: "+boardScores[i];
                LOOKUP[id] = { 'START': (i*divideBoardIntoRadians).toFixed(3), 'END': ((i+1)*divideBoardIntoRadians).toFixed(3), 'VALUE': boardScores[i] };
            }

            for (var name in LOOKUP)
            {
                for (value in LOOKUP[name])
                {
                    console.log( name+":"+value+"="+LOOKUP[name][value] );
                }
            }

答案 0 :(得分：2)

我认为你走错了路。通过CSS定义飞镖靶并将图像作为背景放置在其下方。

以下是一个例子：

＆＃13;
＆＃13; 
$(".circle0").click(function(eve){
  alert(0);
});

$(".circle1").click(function(eve){
  eve.stopPropagation();
  alert("Double something");
});
＆＃13; 
div{
  -webkit-border-radius: 50%;
  -moz-border-radius: 50%;
  border-radius: 50%;
}

.circle0{
  background-color: black;
  width: 500px;
  height: 500px;
}

.circle1{
  background-color: green;
  width: 450px;
  height: 450px;
  margin-top: 25px;
  margin-left: 25px;
  display: inline-block;
}

.circle2{
  background-color: beige;
  width: 430px;
  height: 430px;
  margin-top: 10px;
  margin-left: 10px;
  display: inline-block;
}

.circle3{
  background-color: red;
  width: 300px;
  height: 300px;
  margin-top: 65px;
  margin-left: 65px;
  display: inline-block;
}

.circle4{
  background-color: beige;
  width: 280px;
  height: 280px;
  margin-top: 10px;
  margin-left: 10px;
  display: inline-block;
}

.circle5{
  background-color: green;
  width: 100px;
  height: 100px;
  margin-top: 90px;
  margin-left: 90px;
  display: inline-block;
}

.circle6{
  background-color: red;
  width: 60px;
  height: 60px;
  margin-top: 20px;
  margin-left: 20px;
  display: inline-block;
}
＆＃13; 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="dartboard">
  <div class="circle0">
    <div class="circle1">
      <div class="circle2">
        <div class="circle3">
          <div class="circle4">
            <div class="circle5">
              <div class="circle6">
              </div>
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>

＆＃13;

当然，您可以在我的简单示例中制作更多部分。每个部分为每个＆＃34;数字＆＃34;。 This应该帮助你。
