我在 Wheel of Luck Game 中需要其他帮助。我需要在 6 个 div 中选择 3 个 DIV。但是如果我选择如下图所示的 div 会发生什么，它将分别选择 6 No DIV 而不是 5 或 1。我在下面的代码片段中使用了代码。

enter image description here 

// replacement for localStorage to get snippet working
localStorageX = {
  dic: {},
  setItem: function(key, val) {
    localStorageX.dic[key] = val;
  },
  getItem: function(key) {
    return localStorageX.dic[key];
  },
}

//set default degree (360*5)
var degree = 1800;
//number of clicks = 0
var clicks = 0,
        is_spinning = 0;

$(document).ready(function () {

    /*WHEEL SPIN FUNCTION*/
    $('#spin').click(function () {
        //add 1 every click
        if (is_spinning) {

            return false;
        }
        ;
        is_spinning = 1;
        clicks++;

        /*multiply the degree by number of clicks
         generate random number between 1 - 360,
         then add to the new degree*/
        var newDegree = degree * clicks;
        var extraDegree = Math.floor(Math.random() * (360 - 1 + 1)) + 1;
        totalDegree = newDegree + extraDegree;

        var win_num = 6 - Math.floor((totalDegree % 360 + 30) / 60);

        /*let's make the spin btn to tilt every
         time the edge of the section hits
         the indicator*/
        $('#wheel .sec').each(function () {
            var t = $(this);
            var noY = 0;

            var interval = parseInt(t.data('interval'));
            if (interval > 0) {
                clearInterval(interval);
                t.data('interval', '');
            }

            t.data('interval', setInterval(function () {

                var aoY = t.offset().top;
                $("#txt").html(t.html());
                console.log(aoY);

                /*23.7 is the minumum offset number that
                 each section can get, in a 30 angle degree.
                 So, if the offset reaches 23.7, then we know
                 that it has a 30 degree angle and therefore,
                 exactly aligned with the spin btn*/
                if (aoY < 23.89) {
                    console.log('<<<<<<<<');
                    $('#spin').addClass('spin');

最佳答案

而不是使用 div 或任何其他本质上是正方形的元素，您应该使用具有 6 个区域的图像映射，这样就不会出现任何重叠:

http://www.w3schools.com/tags/tag_map.asp

这里有一个有用的工具，您可以使用它来创建:

https://developer.cdn.mozilla.net/media/uploads/demos/s/u/summerstyle/365ccfd644f2b008c33f0046d2ba1a8f/summer-html-image-ma_1355318513_demo_package/index.html

示例(悬停在 1 或 6 上):

area {
  background-color: rgba(0, 255, 24, 0.4);
}
<img src="http://i.stack.imgur.com/ksl2d.png" alt="" usemap="#map" />
<map name="map">
  <area shape="poly" coords="194, 27, 217, 43, 232, 59, 243, 76, 252, 97, 258, 126, 167, 129, 162, 114, 155, 108, 149, 103" />
  <area shape="poly" coords="71, 27, 91, 17, 120, 10, 148, 9, 180, 16, 188, 20, 145, 102, 132, 98, 123, 101, 113, 107" />
</map>

对于您的，您可以将图像替换为透明的 png，然后映射区域点​​击以影响相关元素。
