使用 React 缺少 MapBox CSS

Missing MapBox CSS using React

我正在尝试使用 React 来处理 MapBox。我已经使用 create-react-app 创建了项目,添加了 mapbox-gl ("mapbox-gl": "^0.46.0-beta.1"),但是 css 文件有问题。它向我显示了这个警告:

This page appears to be missing CSS declarations for Mapbox GL JS, which may cause the map to display incorrectly. Please ensure your page includes mapbox-gl.css, as described inhttps://www.mapbox.com/mapbox-gl-js/api/

我已完成所有步骤:

1 - 安装 npm 包:npm install --save mapbox-gl

2 - 在您的 HTML 文件中包含 CSS 文件:<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.45.0/mapbox-gl.css' rel='stylesheet' />

但是我如何使用与 ES6 的反应,我在 index.js css 文件 import 'mapbox-gl/dist/mapbox-gl.css';

中添加了

如果我导入 css 文件,它不会显示任何内容,如果我评论导入它会显示没有设计的地图,它会显示警告。

我该如何解决???感谢您的帮助

这是我的代码:

import React, { Component } from 'react';

import mapboxgl from 'mapbox-gl';

mapboxgl.accessToken = 'my_token';

class MapComponent extends Component {

  constructor(props) {
      super(props);
      this.state = {
        lng: 1.2217,
        lat: 39.8499,
        zoom: 6.48
      };

    }

  componentDidMount() {
      const { lng, lat, zoom } = this.state;

      var map = new mapboxgl.Map({
        container: 'map',
        center: [lng, lat],
        style: 'mapbox://styles/mapbox/streets-v10',
        zoom: zoom
      });

      map.on('move', () => {
        const { lng, lat } = map.getCenter();

        this.setState({
          lng: lng.toFixed(4),
          lat: lat.toFixed(4),
          zoom: map.getZoom().toFixed(2)
        });
      });
  }

  render() {
      const { lng, lat, zoom } = this.state;
      return (
        <div className="App">
            <div className="inline-block absolute top left mt12 ml12 bg-darken75 color-white z1 py6 px12 round-full txt-s txt-bold">
              <div>{`Longitude: ${lng} Latitude: ${lat} Zoom: ${zoom}`}</div>
            </div>
          <div id="map" />
        </div>
      );
  }
}

export default MapComponent;

解决方案:

正如我所说,我添加了 mapbox-gl.css,import 'mapbox-gl/dist/mapbox-gl.css'; 但没有显示地图。

在 css 文件上显示下一个 css 属性:

<canvas class="mapboxgl-canvas" tabindex="0" aria-label="Map" width="951" height="844" style="position: absolute; width: 951px; height: 844px;"></canvas>

我已经修改了 canvas 个属性:

.mapboxgl-canvas {
    position: fixed !important;
    height: 100% !important;
}

已解决:

1 - import 'mapbox-gl/dist/mapbox-gl.css'; 2 - 覆盖 css class 称为 .mapboxgl-canvas

.mapboxgl-canvas {
    position: absolute;
    top: 0;
    bottom: 0;
    width: 100%;
    height: 100%;
}

1 - 导入 'mapbox-gl/dist/mapbox-gl.css';

2 - 覆盖 css class 调用的 .mapboxgl-canvas

.mapboxgl-canvas {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

1 - 创建一个 randomName.css 文件

2 - 将此代码添加到您的 randomName.css 文件

#yourMapDivName {
position:absolute; 
top:0; 
bottom:0; 
width:100%;
}

body { 
margin:0; 
padding:0;
}

3 - 将“./randomName.css”导入您的 index.js 文件

使用旧版本的 Mapbox 样式表时也会显示警告as described here:

Adding the stylesheet like this doesn't fix the warning:

<!-- index.html -->
<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.42.0/mapbox-gl.css' rel='stylesheet' />

And importing in the app.js like this doesn't work either:

// app.js
import 'mapbox-gl/dist/mapbox-gl.css';

The way I found that fix this problem with the current version of the module is add the updated stylesheet:

<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.53.0/mapbox-gl.css' rel='stylesheet' />

我遇到了同样的问题,这解决了它。
