assets 存放静态资源

components 组件configure 全局配置、路由、redux

layout 页面

redux 合并reducerstyles 样式文件utils 公共方法views 页面入口

代码开发

创建项目路由

src/configure/router/index.js

import React from react;
import {HashRouter, Route, Switch} from react-router-dom;
import Header from "Src/layout/Header";
import Footer from "Src/layout/Footer";
import MapModule from Views/Map/;
import NoFound from Views/NoFound/NpFound;
import {PrivateRoute} from "Shared/AuthorizeFilter";

export default class RouteMap extends React.Component {
render() {
return (
<HashRouter basename="/">
<div className="container_outer" id={container_outer}>
<Header/>
<div className={container_inner} id={container_inner}>
<div className={container_inner_right} id={container_inner_right}>
<div className={container_inner_main} id={container_inner_main}>
{/* 页面 */}
<Switch>
<PrivateRoute exact path="/" component={MapModule} />
<PrivateRoute component={NoFound}/>
</Switch>
</div>
<div className={container_inner_footer} id={container_inner_footer}>
{/* 版权 */}
<Footer />
</div>
</div>
</div>
{/*<Footer/>*/}
</div>
</HashRouter>
);
}
}

初始化地图页面

src/view/Map/index.js

import React from react;
import PureRenderMixin from react-addons-pure-render-mixin;
import {connect} from react-redux;
/**地图样式**/
import Views/Map/map.less;
//地图相关组件
import DciMap from Components/Map/dciMap;

/***地图制图模块核心组件***/
class MapModule extends React.Component {
constructor(props, context) {
super(props, context);
this.shouldComponentUpdate = PureRenderMixin.shouldComponentUpdate.bind(this);
}

render() {
const options = {
dojoConfig: {
has: {
"esri-promise-compatibility": 1
}
},
};
const mapId = dciMainMap;
return (
<div className="page_maps g_clear_fix" id={page_maps}>
<div className="map_canvas" id="map_canvas" stylex={{}}>
<div className="container_map">
<DciMap key={0} mapId={mapId} options={options}/>
</div>
</div>
</div>
)
}
}

初始化地图组件、载入天地图

src/components/Map/DMap.js

const { mapId, initMap } = this.props;
const tileInfo = new TileInfo({
"dpi": 96,
"format": "image/png",
"compressionQuality": 0,
"spatialReference": new SpatialReference({
"wkid": 4490
}),
"rows": 256,
"cols": 256,
"origin": {
"x": -180,
"y": 90
}
