Leaflet教程(1)--小功能效果

1 移动和缩放

// disable drag and zoom handlers

//禁止移动和放大缩小

map.dragging.disable();

map.touchZoom.disable();

map.doubleClickZoom.disable();

map.scrollWheelZoom.disable();

// disable tap handler, if present.

//禁止单击

if (map.tap) map.tap.disable();

2 单击事件

var popup = new L.popup();
       function onMapClick(e) {

                   popup

                            .setLatLng(e.latlng)

                            .setContent("You clicked the map at " + e.latlng.toString())

                            .openOn(map);

         }

         map.on('click', onMapClick);

3 添加缩放控制zoom，在右下角

var zoomControl = L.control.zoom({

                   position: 'bottomright'

         });

         map.addControl(zoomControl);

 

4 添加比例尺

L.control.scale().addTo(map);

 

5 瓦片图层加载

L.tileLayer('http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer/tile/{z}/{y}/{x}',{

                   maxZoom: 18,

                   reuseTiles: true                         

         }).addTo(map);

 

6 添加底图(esri-leaflet插件)

 需要引入esri-leaflet.js

github：https://github.com/esri/esri-leaflet

百度盘下载：http://pan.baidu.com/s/1nt0S2JR

L.esri.basemapLayer("Streets").addTo(map);//此行可行

         //ArcGIS Server Dynamic Map Service, Historic Hurricane Tracks

                   dynLayer = L.esri.dynamicMapLayer(kaifaqu, {

                   opacity: 1,

                   layers: [0, 1]

         });

         map.setView([30.60, 119.65], 9); //浙江

定位

function onLocationFound(e) {

                   var radius = e.accuracy / 2;

 
                   L.marker(e.latlng).addTo(map)

                            .bindPopup("You are within " + radius + " meters from this point").openPopup();

 
                   L.circle(e.latlng, radius).addTo(map);

         }

 
         map.on('locationfound', onLocationFound);

7 添加shapefile

来自（http://www.cnblogs.com/wangcan/）

需要引入shapefile.js

github:https://github.com/calvinmetcalf/shapefile-js

百度盘（shp.min.js下载后引入即可）：http://pan.baidu.com/s/1hq5MuDe

//添加shapefile
function addShapeFile() {

    map.setView([34.74161249883172, 18.6328125], 2);
    var geo = L.geoJson({
        features: []
    }, {
        onEachFeature: function popUp(f, l) {
            //console.info(f);
            var out = [];
            if (f.properties) {
                for (var key in f.properties) {
                    out.push(key + ": " + f.properties[key]);
                    
                }
                l.bindPopup(out.join("<br />"));
            }
        }
    })//.addTo(map);
    
    //保存到 图层数组
    map_layers.push(geo);
    //此处指向shapefile的zip文件即可
    var base = 'files/bou1_4m.zip';
    shp(base).then(function(data) {
        console.info(data);
        geo.addData(data);
    });
}
