GIS工具maptalks开发手册(四)01——渲染地图信息框之添加绘制工具、获取点的坐标数据信息框进行展示

1、官网示例

官网示例-地图信息框——https://maptalks.org/examples/cn/ui-control/ui-map-infownd/#ui-control_ui-map-infownd

效果

在这里插入图片描述

        zoom: 14,

      });

      var options = {
        'title'     : 'Map\' InfoWindow',
        'content'   : 'Click on map to reopen'

        // 'autoPan': true,
        // 'width': 300,
        // 'minHeight': 120,
        // 'custom': false,

      };
      var infoWindow = new maptalks.ui.InfoWindow(options);
      infoWindow.addTo(map).show();

    </script>
  </body>
</html>

2、官网示例改造版

效果

在这里插入图片描述

index.html

<!DOCTYPE html>

<meta name="viewport" content="width=device-width, initial-scale=1">

<style type="text/css">
  html,
  body {
    margin: 0px;
    height: 100%;
    width: 100%;
  }

  .container {
    width: 900px;
    height: 500px;
    margin: 50px;
  }
</style>
<link rel="stylesheet" href="https://unpkg.com/maptalks/dist/maptalks.css">
<script type="text/javascript" src="https://unpkg.com/maptalks/dist/maptalks.min.js"></script>

<body>

  <div id="map" class="container"></div>
  <script>
    var map = new maptalks.Map('map', {
      center: [-0.113049, 51.49856],
      zoom: 14,
      baseLayer: new maptalks.TileLayer('base', {
        urlTemplate: 'https://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png',
        subdomains: ['a', 'b', 'c', 'd'],
        attribution: '&copy; <a href="http://osm.org">OpenStreetMap</a> contributors, &copy; <a href="https://carto.com/">CARTO</a>'
      })
    });

    var options = {
      // 题目
      'title': 'Map\' InfoWindow-地图信息窗',
      // 内容
      'content': 'Click on map to reopen-点击重新打开地图',
      // 自动平移
      'autoPan': true,
      'width': 340,
      'minHeight': 120,
      // 自定义属性
      // 'custom': false,
      // 自动打开方式
      // 'autoOpenOn' : 'click',  //set to null if not to open window when clicking on map （如果单击地图时不打开窗口，则设置为空）
      // 自动关闭方式
      // 'autoCloseOn' : 'click'
    };
    var infoWindow = new maptalks.ui.InfoWindow(options);
    infoWindow.addTo(map).show();

  </script>
</body>

</html>

3、获取图层的坐标-信息框展示图层的坐标

效果1-打印点的坐标

在这里插入图片描述

效果2-信息框中展示点的坐标
