:::info 在对应的图层上，根据id进行删除 :::

一、MapGIS Desktop中查询id

删除点，首先要找到点要素的id（featureIds）

二、IG Server中查询图层

三、演示代码

  1. <body>
  2.     <!-- 2、创建地图容器 -->
  3.     <button onclick="deletePoint()">删除</button>
  4.     <div id="map_container">
  5.     </div>
  6.     <!-- 3、实例化对象 -->
  8.     <script>
  9.         const docLayer = new Zondy.Map.Doc('', 'city', {
  10.             ip: 'localhost',
  11.             port: 6163
  12.         })
  13.         const map = new ol.Map({
  14.             target: 'map_container',
  15.             layers: [gaode, docLayer],
  16.             view: new ol.View({
  17.                 projection: 'EPSG:4326',
  18.                 center: [114, 30],
  19.                 zoom: 4
  20.             })
  21.         })
  22.         function deletePoint(){
  23.             var featureIds = '13'
  24.             var deleteService = new Zondy.Service.EditDocFeature(
  25.                 'city',//IG Server中地图文档
  26.                 2,  //图层
  27.                 {
  28.                     ip:'localhost',
  29.                     port:'6163'
  30.                 }
  31.             )
  32.             deleteService.deletes(featureIds,onSuccess)
  33.         }
  34.         function onSuccess(data) {
  35.             if (data.succeed) {
  36.                 alert('添加成功')
  37.                 docLayer.refresh(); //重新加载地图文档
  38.             } else {
  39.                 alert('添加点要素失败')
  40.             }
  41.         }
  42.     </script>
  43. </body>
  45. </html>
