jQuery插件imagemapster没有做任何事情

Question

我对 javascript 和 jQuery 还比较陌生，所以请记住，这可能是我看不到的明显解决方案。

我引用了 jQuery，它适用于其他事情。也许 imagemapster 参考有问题？我下载了它here 并像这样引用它。我也放了“imagemapster.min.js”，但是两个都放的时候不行，自己用的时候也不行。

<script type="text/javascript" src="../SiteAssets/css/jquery.imagemapster.js"></script>
<script type="text/javascript" src="../SiteAssets/css/jquery.imagemapster.min.js"></script>

我阅读了文档并几乎完全遵循了它（见下文），但它实际上对突出显示没有任何作用。相反，它会稍微弄乱他们的定位，从而破坏页面，这是没有意义的，因为 mapster 应该与定位无关。可点击区域也已向上移动并移出位置。它甚至没有给出任何错误；代码只是通过，除了我说的什么都没有发生。是的，我要强调的图像地图功能齐全，#downstairs、#upstairs 和 #offices 确实是图像标签的 ID，就像它们应该是的那样。

$(document).ready(function()
{
    $('#downstairs').mapster({
        fillOpacity: 0.5,
        mapKey: 'alt',
        isSelectable: false,
        render_highlight:
        {
            fillColor: '2aff00'
        }
    });

    $('#upstairs').mapster({
        fillOpacity: 0.5,
        mapKey: 'alt',
        isSelectable: false,
        render_highlight:
        {
            fillColor: '2aff00'
        }
    });

    $('#offices').mapster({
        fillOpacity: 0.5,
        mapKey: 'alt',
        isSelectable: false,
        render_highlight:
        {
        fillColor: '2aff00'
        }
    });
});

这是图像和地图的 html。他们三个都使用这种格式。

<div style="position:static;left:0px;top:0px">
<img id="downstairs" alt="downstairs" class="map" usemap="#downmap" style="visibility:visible;z-index:3; left: 10px; top: 54px;"
    src="sourceHere" width="1000" />
<map name="downmap" id="downmap">
    <!-- There is a large list of areas here that follow this format-->
    <area title="Portable 1" onclick="somefunction" coords="198,81,223,117" />
</map>
</div>

Answer 1

检查您的地图区域是否定义了 href。例如：href="#"

Answer 2

在将脚本移到地图下方之前，我遇到了类似的问题。我在文档中找不到它，但我记得读过要使插件工作，必须先加载图像。您仍然需要在头部调用插件，但您需要将 javascript 放在图像映射之后。

Answer 3

当我第一次尝试 ImageMapster 时，我没有正确设置路径。您的区域路径必须从上到下环绕对象，然后从左到右，然后从下到上，直到它在开始时再次相遇。一旦我这样做了，ImageMapster 就“做了一些事情”。在我找到正确的路径之前，它看起来就像什么都没有发生。

您还必须告诉image 使用map。

<div id="mapblock">
    <img id="map_image" src="/images/map.png" usemap="#map_map"/>
    <map name="map_map">
        <area data-key="AZ" full="item" href="#" coords="... " shape="poly" />
    </map>
</div>

另外，您在代码中使用的 ID# 应该是 image 的 ID，而不是地图的 ID。

另外，请确保您的地图区域在图像内（您可能必须设置图像的width，您知道）否则悬停效果将不会显示。当我第一次尝试时，在确定我的区域位于正确的位置之前，我什么也没看到。

我写了一个 mini-tutorial here 用于使用 Photoshop 和 Illustrator 生成 image-map。这对我来说效果很好，image-map 就在完美的位置。

[在 OP 发布 imagemap html 之后]

<area title="Portable 1" onclick="somefunction" coords="198,81,223,117" />

啊，我想你的坐标很匹配。把坐标想象成一条线。您已经描述了行的开头加上另一点 - 您必须告诉它进行完整循环。试试这个，看看会发生什么：

'coords="198,81, 223,117, 198,81"

Answer 4

对于 imagemapster 使用 jquery 2.1.3

<!-- not this
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> -->

<!-- use this one -->
<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js'></script>

用于图像映射器

<script src="http://www.outsharked.com/scripts/jquery.imagemapster.js"></script>

同样的情况发生在我的图像地图悬停在更改版本后最终无法显示或工作正常。

参考下面的代码：

<!-- <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> -->
