  • 使用echarts简单制作中国地图,echarts中国地图

    网站需要一张中国地图,并且鼠标经过某个省份,该省份的省份名字显示,而且该省份的地区会变色显示。

    第一种方法:

    将每个省份的图片定位(先隐藏),拼合成一张中国地图,然后再定位省份名称,鼠标经过省份名字,添加hover事件,将对应图片显示。

    第二种方法:

    使用图形插件echarts,轻松制作。

    http://echarts.baidu.com/doc/example.html在echarts网站上下载文件包

    echarts使用方法查看页面

    http://echarts.baidu.com/doc/doc.html#%E5%BC%95%E5%85%A5ECharts3

    可以在网站上调整好需要的样式再放到本地看效果

    自己试验的demo如下:

    <!doctype html>
    <html>

    <head>
        <meta charset="utf-8">
        <title>echarts图形插件使用</title>

    </head>

    <body>
        <div id="main" style="height:800px;"></div>
        <script type="text/javascript" src="js/echarts-all.js"></script>
        <script type="text/javascript">
            var myChart = echarts.init(document.getElementById('main'));
