悬停地图区域精灵与jquery

Question

我正在我的第一个实际的WordPress的网站，我有一些jQuery的麻烦。我真的希望有人能帮助我。

所以我想要做的是根据当前悬停的地图区域来定位我的div背景。

我发现这里的例子：http://ubytujnaslovensku.sk/sk/

我得到了什么： HTML：

<div id="front-cubus-wrapper"> 
     <div id="front-cubus"></div> 
     <div id="front-cubus-hover" style="background-position: 0px 0px;" ></div> 
     <img alt="cubus" src="/wp-content/uploads/2013/10/cubus_index_blanko.png" usemap="#map"/> 
      <map id="map" name="map"> 
       <area title="Communication" alt="Communication" shape="poly" coords="119,101,286,34,347,55,180,124" href="#"> 
       <area title="Governance" alt="Governance" shape="poly" coords="59,79,228,17,281,34,115,99" href="#"> 
       <area title="Leadership" alt="Leadership" shape="poly" coords="55,78,223,16,173,2,3,58" href="#"> 
       <area title="Strategy" alt="Strategy" shape="poly" coords="179,127,2,61,6,133,179,207" href="#"> 
       <area title="Implementation" alt="Implementation" shape="poly" coords="179,212,6,138,9,206,180,286" href="#"> 
       <area title="Operation" alt="Operation" shape="poly" coords="180,290,9,210,12,278,179,362" href="#"> 
       <area title="Corporate" alt="Corporate" shape="poly" coords="182,126,225,110,223,341,183,359" href="#"> 
       <area title="Business units" alt="Business units" shape="poly" coords="230,108,271,91,265,319,228,340" href="#"> 
       <area title="Business functions" alt="Business functions" shape="poly" coords="275,89,313,73,305,294,268,317" href="#"> 
       <area title="Potential partner" alt="Potential partner" shape="poly" coords="315,71,351,55,342,272,308,292" href="#"> 
      </map> 
    </div> 

CSS

#front-cubus-wrapper{ 
width:355px; 
height:365px; 
position:relative; 
} 

#front-cubus{ 
width:355px; 
height:365px; 
position: absolute; 
background-image:url(images/insighttoimprove_website_cubus_index.png); 
z-index:1; 
} 

#front-cubus-hover{ 
width:355px; 
height:365px; 
position: absolute; 
background-image:url(images/insighttoimprove_website_cubus_index_hover.png); 
background-repeat:no-repeat; 
z-index:2; 
} 

#front-cubus-wrapper img{ 
position:absolute; 
width:355px; 
height:365px; 
z-index:3; 
} 

的Jquery：

jQuery(document).ready(function($){ 

var default_value = $("#front-cubus-hover").css("background-position"); 
if (default_value === "0px 0px") { 
$('#map area').each(function() { 

    $(this).hover(
     function() { 
      var yposition = -1*365*($(this).index()+1); 
      $("#front-cubus-hover").css("background-position","0 "+yposition+"px"); 
}, 
     function() { 
      $("#front-cubus-hover").css("background-position",default_value); 
     } 
    ); 
}); 
} 
});

我我也在研究类似的项目。这是我的解释代码。

HTML

<img src="images/car.jpg" alt="car" usemap="#carmap" width="1100px" height="700px" /> 
<map name="carmap"> 
    <area shape="rect" coords="0,0,200,150" alt="door" href="#" class="door1"> 
    <area shape="rect" coords="453,404,533,704" alt="door" href="#" class="door2"> 
</map> 

<div class="door1"></div> 

<div class="door2"></div> 

CSS

img{ 
    position: relative; 
} 

div.door1{ 
    width: 200px; 
    height: 150px; 
    position: absolute; 
    top: 0; 
    left: 0; 
    display: none; 
    background: blue; 
    pointer-events:none; 
} 

div.door2{ 
    width: 180px; 
    height: 300px; 
    position: absolute; 
    left: 453px; 
    top: 404px;     
    background: url("images/tire-modified.jpg") no-repeat left top; 
    pointer-events:none; 
    border-radius: 50%; 
} 

jQuery的

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script> 
<script> 
    $(document).ready(function(){ 

     $("div.door1").hide(); 
     $("area.door1").mouseenter(function(){ 
      $("div.door1").show(); 
     }); 

     $("area.door1").mouseleave(function(){ 
      $("div.door1").hide(); 
     }); 

     $("area.door2").mouseenter(function(){ 
      $("div.door2").show(); 
     }); 

     $("area.door2").mouseleave(function(){ 
      $("div.door2").hide(); 
     }); 

    }); 
</script> 

所以，首先我用相对位置和对图像两个区域映射设置图像。现在，在该地图悬停部分，我绑定了mouseenter和mouseleave事件，以便可以设置其他div（根据区域），我可以将它们设置为绝对位置。不要忘记添加指针事件：无;对你的绝对元素，以便没有事件适用于这些元素。否则，闪烁的问题将在那里。我希望这会对你有所帮助。
