高德地图进阶开发实战案例(5):矩形可视范围的东北西南角经纬度的获取

    var map = new AMap.Map('container', {
        center: [ 116.387175, 39.876405 ],
        zoom: 13
    });

    var southWest = new AMap.LngLat(116.356449, 39.859008)
    var northEast = new AMap.LngLat(116.417901, 39.893797)

    var bounds = new AMap.Bounds(southWest, northEast)

    var rectangle = new AMap.Rectangle({
        bounds: bounds,
        strokeColor:'red',
        strokeWeight: 6,
        strokeOpacity:0.5,
        strokeDasharray: [30,10],
        strokeStyle: 'dashed',
        fillColor:'blue',
        fillOpacity:0.5,
        cursor:'pointer',
        zIndex:50,
    })

    console.log(rectangle.getBounds());

    rectangle.setMap(map)
    // 缩放地图到合适的视野级别
    map.setFitView([ rectangle ])

    var rectangleEditor = new AMap.RectangleEditor(map, rectangle)

    rectangleEditor.on('adjust', function(event) {
        log.info('触发事件：adjust')
    })

    rectangleEditor.on('end', function(event) {
        log.info('触发事件： end')
        // event.target 即为编辑后的矩形对象
    })

<div class="input-card" style="width: 120px">
    <button class="btn" onclick="rectangleEditor.open()" style="margin-bottom: 5px">开始编辑</button>
    <button class="btn" onclick="rectangleEditor.close()">结束编辑</button>
</div>
