[百度地图] ZMap 与 MultiZMap 封装类说明;

ZMap.js 与 MultiZMap 说明

1. ZMap 与 MultiZMap 都是封装一些地图常用的使用方法，类方法功能大多使用 prototype 原型 实现；

ZMap 在一个页面只能使用一次；多次使用会冲突;

MultiZMap 在一个页面上可以使用多次，它是 ZMap 的多加载版本，主要用于类似 DWZ 这个 多标签的 UI 的框架；

2. 包含的功能有：轨迹回放，圈画区域可编辑，判断几个坐标是否在一个圆圈内，生活服务查询，
从经纬度获取地址信息，地图工具包括测距，获取面积，以积打印地图，地图全屏，实时路况，坐标是否在polygon区域内，
打车方案，经过中间途经点，添加地图控件；

3. 功能界面:

介绍MultiZMap.js 使用，ZMap类似;

1. 相关脚本引入:

<link href="http://api.map.baidu.com/library/TrafficControl/1.4/src/TrafficControl_min.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="/devices/scripts/jquery-1.7.2.js"></script>
    <script type="text/javascript" src="http://api.map.baidu.com/api?v=1.2&services=true"></script>
    <script type="text/javascript" src="http://api.map.baidu.com/library/DistanceTool/1.2/src/DistanceTool_min.js"></script>
    <script type="text/javascript" src="http://api.map.baidu.com/library/TrafficControl/1.4/src/TrafficControl_min.js"></script>
    <script type="text/javascript" src="/devices/scripts/GeoUtils.js"></script>
    <script type="text/javascript" src="/devices/scripts/MultiZMap.js"></script>

2. HTML 结构:

<div id="container" style="margin:0px auto; width:700px; height:600px; padding-bottom: -40px; overflow: hidden;">
        <div id="panel" style="height:30px; width:100%; display:none; background: #6485ed;">
            <span>X</span>
        </div>
        <div id="istmap" style="width:100%; height:640px;"></div>
</div>

3. 地图初始化创建:

var multiMap;
function initMap() {
            multiMap = new MultiZMap({
                container: 'container',
                mapId: 'istmap'
            });
    multiMap.create();
}

4. 使地图可滚轮放大缩小:

multiMap.enables.scrollWheel();

5. 添加工具控件:

multiMap.controls.addNavi({});
multiMap.controls.addScale({offset:new BMap.Size(0, 40)});
multiMap.controls.addOverview({isOpen: true, offset:new BMap.Size(0, 40)});
multiMap.controls.addMapType({});

6. 轨迹回放：

var guiji ;
function guiJiMap() {
    guiji = new multiMap.GuiJiPlay({
                marker: {
                    marker: null,
                    label:'车'
                }
            });
            var pointsStr = '116.401072,39.913859-116.401242,39.913859-116.401431,39.913873-116.401844,39.913886-116.402257,39.9139-116.402608,39.9139-116.402994,39.913914-116.403416,39.913928-116.403784,39.913942-116.404135,39.913949-116.404557,39.913962-116.405015,39.913997-116.405455,39.914004-116.405815,39.914011-116.406228,39.914045-116.406587,39.914045-116.406955,39.914059-116.407719,39.914052-116.40886,39.914108-116.408788,39.914101-116.409192,39.914101-116.409462,39.914108-116.409848,39.914115-116.410297,39.914163-116.410953,39.914239';
    var arrs = pointsStr.split('-');
    guiji.set(arrs);
}

guiji.set有第二个参数，可设置Marker显示；

7. 画圈，可编辑:

var linearea;
function lineAreaMap() {
    linearea = new multiMap.lineArea({
                color:'red',
                callback : function(points, gon) {

                }
            });
}

linearea.edit(); 可编辑;

8. 查看物体集合是否在圆圈内:

function circleSearchMap() {
    var cars = ['116.40329,39.915851', '116.403757,39.915816', '116.403722,39.915284', '116.40303,39.91482', '116.402455,39.915138','116.402105,39.915464','116.403308,39.915706','116.405392,39.914654'];

    multiMap.setZoom(18);
    var point = multiMap.getPoint('116.40329,39.915851');
    multiMap.panTo(point);
    var inC = new multiMap.inCircleSearch();
    inC.set({
                point: point,
                distance: 200,
                markered : true,
                show : true,
                sign : {
                    Yes: '在圈内'
                }
            });
    inC.searchs(cars);
    multiMap.enables.scrollWheel();
}

9. 地图全屏

var fullmap;
function fullMap() {
    fullmap = new multiMap.XfullMap({
                //container : 'container',
                //mapId : 'istmap',
                fullfunc : function() {
                    $('#panel').css('display','block');
                },
                origifunc : function() {
                    $('#panel').css('display','none');
                }
            });
        var point = multiMap.mapObj.getCenter();
    fullmap.toFull(point);
}

关闭全屏:

var point = multiMap.mapObj.getCenter();
fullmap.toOrigi(point);

12. 事件管理:

1. 地图事件管理:

mutlMap.addListener('eventType', function(e) {
    //添加 地图 eventType 类型事件;
});

multiMap.events.add('唯一事件Key', MapItem, 'eventType', function(e) {
    //添加 地图控件MapItem, eventType 类型事件;
});
