便利贴--5{OpenLayers,vue项目}

项目

添加
“ol”: “^6.5.0”,
“olcs”: “^2.12.0”
在package.json中添加

OpenLayers–需要 Cesium

链接: 贴出Cesium下载.
链接: jqurey，drawTree支持下载.
main.vue

由于绘画的Draw.js没有找到想要输出数据的地方，只能自己改，但是每次拉包会重置node_modules所有的文件，所以把Draw.js直接从ol/interaction中拿出来，改好就引用这个js

改的话因为比较长还是放在文件中自己下载
0积分

tip.vue


<template>
  <div
    class="mapTip"
    :style="{ top: position.h + 'px', left: position.w + 'px' }"
  >
    {{ title }}
  </div>
</template>

<script>
export default {
  props: ["title", "position"],
};
</script>

<style lang="scss" scoped>
.mapTip {
  background-color: rgb(168, 168, 168);
  padding: 5px;
  border: 1px solid #000;
  position: absolute;
  z-index: 10 !important;
  border-radius: 5px;
}
</style>

最后用Store传送数据

   rotesData: false,
   
   setRotesData(state, data) {
      state.rotesData = data;
    }
