從javascript映像更改img src文件夾

Question

我使用mapster製作了9個區域的映像。現在單擊某個區域會在圖像上方顯示一些文字。我想顯示來自多個文件夾的圖像，取決於所選的區域。當在圖像地圖上選擇區域'kamer1'時，我希望文件夾'/ kamer1'中的所有圖像顯示在圖像地圖上方。

這是我第一次使用JavaScript，所以期待這是一個簡單的問題。

HTML：

<div style="clear: both; width: 900px; height: 450px;" id="details"></div> 
<img id="layout" src="http://i61.tinypic.com/2yl4spc.png" usemap="#usa" style="width:900px;height:800px;"> 
<map id="usa_image_map" name="usa"> 
    <area href="#" room="kamer1" full="B&B" shape="rect" coords="50,764,143,635"> 
    <area href="#" room="kamer2" full="B&B" shape="rect" coords="146,764,238,669"> 
    <area href="#" room="kamer3" full="B&B" shape="rect" coords="241,764,326,669">

</map> 

JS：

var xref = { 
    kamer1: "<b>FOTO's van kamer 1</b>", 
    kamer2: "<b>FOTO's van kamer 2</b>", 
    kamer3: "<b>FOTO's van kamer 3</b>", 
    hal: "<b>FOTO's van hal</b>", 
    badkamer: "<b>FOTO's van badkamer</b>", 
    keuken: "<b>FOTO's van keuken</b>", 
    boven: "<b>FOTO's van boven kamer</b>", 
    kamer4: "<b>FOTO's van kamer 4</b>", 
    kamer5: "<b>FOTO's van kamer 5</b>" 
}; 

var image = $('#layout'); 

image.mapster({ 
    fillOpacity: 0.5, 
    fillColor: "c20000", 
    stroke: true, 
    strokeColor: "c20000", 
    strokeOpacity: 0.8, 
    strokeWidth: 3, 
    singleSelect: true, 
    mapKey: 'room', 
    listKey: 'room', 
    clickNavigate: true,

    showToolTip: true, 
    toolTipContainer: '<div style="clear: both; align: center;"></div>', 
    areas: [{ 
     key: "kamer1", 
     toolTip: "Groepsaccommodatie <br> kamer 1" 
    }, { 
     key: "kamer2", 
     toolTip: "Groepsaccommodatie <br> kamer 2" 
    }, { 
     key: "kamer3", 
     toolTip: "Groepsaccommodatie <br> kamer 3" 
    }, { 
     key: "hal", 
     toolTip: "Groepsaccommodatie <br> hal" 
    }, { 
     key: "badkamer", 
     toolTip: "Groepsaccommodatie <br> badkamer" 
    }, { 
     key: "keuken", 
     toolTip: "Keuken en eetkamer" 
    }, { 
     key: "boven", 
     toolTip: "Recreatieruimte" 
    }, { 
     key: "kamer4", 
     toolTip: "Bed & Breakfast <br> kamer 1" 
    }, { 
     key: "kamer5", 
     toolTip: "Bed & Breakfast <br> kamer 2" 
    }], 

    onClick: function (e) { 
     $('#details').html(xref[e.key]); 
    } 
}); 

Answer 1

var xref = { 
    kamer1: { 
     "desc":"FOTO's van kamer 1", 
     "images":["stoel.jpg","tafel.jpg"] 
    }, 
    kamer2: { 
     "desc":"FOTO's van kamer 2", 
     "images":["image1.jpg","image2.jpg"] 
    } 
}; 
// note the lack of comma on the last room 

onClick: function (e) { 
    e.preventDefault(); 
    var room = xref[e.key]; 
    var html = '<b>'+room.desc+'</b><br/>'; 
    for (var i=0;i<room.images.length;i++) 
    html += '<img src="'+images[i]+'" alt="image #'+(i+1)+'" />'; 
    $('#details').html(html); 
} 

如果你不知道的圖像數量或名稱可以試試這個：

var xref = { 
    kamer1: "FOTO's van kamer 1", 
    kamer2: "FOTO's van kamer 2", 
    kamer3: "FOTO's van kamer 3" 
} 
onClick: function (e) { 
    e.preventDefault(); 
    var html = '<b>'+xref[e.key]+'</b><br/>'; 
    var imagePath = e.key+"/"+e.key+"_"; 
    for (var i=1;i<=5;i++) { 
    html += '<img src="'+imagePath+i+'" alt="image #'+(i+1)+'"'+ 
    ' onerror="this.parentNode.removeChild(this)" />'; 
    } 
    $('#details').html(html); 
}
