ZMap.js 本地搜索方法 及 中间点附近查找方法 

1. 本地搜索方法:

/**
 * 本地搜索,生活服务查询
 * @param opts
 * @param flag
 * @returns {ZMap.liveSearch}
 */
ZMap.liveSearch = function(opts, flag) {
    if (flag) {
        ZMap.createMap(ZMap.mapId, ZMap.opts);
    }
    
    var autoview = (typeof opts.view == 'boolean') ? opts.view : true;
    
    this.local = new BMap.LocalSearch(ZMap.mapObj, {renderOptions: {map: ZMap.mapObj, autoViewport: autoview, panel: (opts.panelId || '')}});
    this.callback = opts.callback;
    this.markercall = opts.markercall;
    this.init();
};

ZMap.liveSearch.prototype.init = function(){
    var me = this;
    me.local.setSearchCompleteCallback(function(rs) {
        if (me.local.getStatus() == BMAP_STATUS_SUCCESS) {
            //var poi = rs.getPoi(0);
            //var point = poi.point;
            //var address = poi.address;
            //var city = poi.city;
            //var phone = poi.phoneNumber;
            //var zip = poi.postcode;
            //var province = poi.province;
            //var tags = poi.tags; //array
            //var title = poi.title;
            //var resCount = res.getCurrentNumPois();
            me.callback && me.callback(rs);
        }
    });
    
    me.local.setMarkersSetCallback(function(pois) {
        /*
         * for (var i=0;i<pois.length;i++) {
         *     var marker = pois[i].marker;
         * }
         */
        //var poi = pois[i]; 
        //poi 包含 属性上同 callback
        //这里的 poi.marker 是真正的 BMap.Marker
        //上面 callback 的 poi.marker 只是 BMap.Overlay
        me.markercall && me.markercall(pois);
    });
};

//矩形区域搜索
ZMap.liveSearch.prototype.searchBounds = function(items) {//items 数组 ['酒店','银行'...]
    var me = this;
    var bo = ZMap.mapObj.getBounds();
    me.local.searchInBounds(items ,bo);
};

//智能搜索
ZMap.liveSearch.prototype.search = function(addr) {
    var me = this;
    me.local.search(addr);
};

//附近搜索
ZMap.liveSearch.prototype.nearBy = function(addr, point, distance) {
    var me = this;
    me.local.searchNearby(addr, point, distance);
};

支持搜索结果 及 标注(Marker, 消息框) 自定义;

2. 中心点附近查找方法:

/**
 * 是否在圆圈范围内
 * @param flag
 * @returns {Array}
 */
ZMap.inCircleSearch = function(flag) {
    if (flag) {
        ZMap.createMap(ZMap.mapId, ZMap.opts);
    }
    
    this.point = null;
    this.distance = 500;
    this.show = true;
    this.circle = null;
    this.inCircles = [];
    this.markers = [];
    this.markered = false;
};

ZMap.inCircleSearch.prototype.set = function(opts) {
    var me = this;
    
    me.clear();
    
    me.clearCircle();

    me.distance = opts.distance || 500;
    me.point = opts.point || ZMap.mapObj.getCenter();
    me.show = opts.show || true;
    me.callback = opts.callback || function() {};
    me.markered = opts.markered || false;
    
    if (me.show) {
        me.circle = new BMap.Circle(me.point, me.distance ,{strokeColor:"blue", strokeWeight:2, strokeOpacity:0.5});
        ZMap.mapObj.addOverlay(me.circle);
    }
};

ZMap.inCircleSearch.prototype.clearCircle = function() {
    var me = this;
    if (me.circle) {
        ZMap.mapObj.removeOverlay(me.circle);
    }
};

ZMap.inCircleSearch.prototype.clear = function() {
    var me = this;
    if (me.markers && me.markers.length > 0) {
        for (itm in me.markers) {
            var marker = me.markers[itm];
            if (marker instanceof BMap.Marker) {
                ZMap.mapObj.removeOverlay(marker);
            }
        }
    }
    
    me.markers = [];
    me.inCircles = [];
};

ZMap.inCircleSearch.prototype.search = function(pointArr) {
    var me = this;
    
    me.clear();
    
    for (itm in pointArr) {
        var one = pointArr[itm];
        var _point = ZMap.getPoint(one);
        
        if (_point) {
            
            var distance = ZMap.mapObj.getDistance(me.point, _point);
            distance = parseFloat(distance);
            console.log(distance + '-' + me.distance);
            var sign = 'No';
            if (distance <= me.distance) {
                me.inCircles.push(_point);
                sign = 'Yes';
            }
            
            if (me.markered) {
                var marker = ZMap.labelMarker(sign, _point);
                me.markers.push(marker);
            }
            
            me.callback && me.callback(sign, _point);
        }
        
    }
    
    return me.inCircles;
};

支持定义是否显示圆圈,是否标注结果,查找后返回符合的结果 及 处理回调方法;

页面处理脚本 ddsscz.js 代码说明:

1. 全局成员,摸拟车及人,地图招始化显示在地图上;

//模拟
var cars = ['116.366263,40.049681','116.312221,40.019187','116.492169,40.062052','116.45135,39.959484','116.593355,39.96966','116.515741,40.094293','116.551386,39.896187'];
var peos = ['116.41858,40.064261','116.396159,39.922752','116.343266,39.974526','116.48872,40.004598','116.531839,40.071328','116.577257,40.008135'];
var cs;

cs 中心附近查找方法;

2. 界面地图初始化:

jQuery(document).ready(function() {
    defaultMap();
    
    initMap();
});


function defaultMap() {
    
    ZMap.createMap('istmap', {
        lng: 116.404,
        lat: 39.915,
        level: 15,
        callback: function() {
            var height = $('#baiduMap').height();
            console.log(height);
            $('#istmap').height((height + 40)+'px');
        }
    });
    
    ZMap.enables.scrollWheel();

    /*
    ZMap.addListener(ZMap.mapObj, 'click', function(e) {
        $('#resDiv').html(e.point.lng+','+e.point.lat);
    });
    */
    
    cs = new ZMap.inCircleSearch();
};

function initMap() {
    //car
    for (itm in cars) {
        var car = cars[itm];
        var point = ZMap.getPoint(car);
        point && ZMap.iconMarker({
            img: '/basic/themes/images/gis/car.png',
            width : 24,
            height : 24
        }, point);
    }
    
    //peo
    for (itm in peos) {
        var peo = peos[itm];
        var point = ZMap.getPoint(peo);
        point && ZMap.iconMarker({
            img: '/basic/themes/images/gis/peo.png',
            width : 24,
            height : 24
        }, point);
    }
}

地图初始化,支持地图鼠标滚轮放大缩小;

initMap: 用于把摸拟的车跟人显示在地图上;

3. 实现上图 左侧 的搜索,用于模糊 查询关键字 ,如: 银行、餐饮等,返回当前地图位置附近的相关信息;

function searByaddr() {
    $('#cartable table').html('');
    
    var livesearch = new ZMap.liveSearch({
        view : true,
        callback : function(rs) {
            
            //清空 Overlay
            //ZMap.clear();
            
            var num = rs.getCurrentNumPois();
            
            var addrs = [];
            for (var i=0;i<num;i++) {
                var poi = rs.getPoi(i);
                var trbg = ((i+1) == 1 || (i+1) % 2 != 0) ? "trbg" : "";
                addrs.push('<tr class="'+trbg+'" oricls="'+trbg+'">');
                addrs.push('    <td style="width:20px;">' + (i+1) + '<input type="hidden" value="'+poi.point.lng+","+poi.point.lat+'" /></td>');
                addrs.push('    <td style="text-align:left; padding: 6px 0 3px 0;">');
                addrs.push('    <span style="font-weight:bold;font-size:13px;">' + poi.title + '</span><br />');
                addrs.push('    地址: <span>' + poi.address + '</span><br />');
                addrs.push('    </td>');
                addrs.push('</tr>');
                
                /*
                (function(point, title, addr, n) {
                    var marker = ZMap.labelMarker((n+1), point);

                })(point, title, address, i);
            }
        }
    });
    
    var key = $.trim($('#addrSear').val());
    
    if (key == '') {
        alertMsg.confirm('请输入查询关健字!');
        return false;
    }
    
    livesearch.search(key);
}

ZMap.liveSearch(opts); 

opts 是 json 格式数据; 字段及方法有:

view: 查询结果是否在地图显示范围内;

panelId: 地图查询结果,默认的文本结果显示位置; panelId 是某容器 id, 如<div id="panelId"></div>;

callback: 查询结果回调方法;

markercall: 查询结果后,用于处理 标注 的自定义回调方法;

本方法用于 将查询结果,显示在左侧块,自定义 table tr 列表序号显示出来,并实现列表的 样式 及 点击效果;

并自定义 地图结果标注 (Marker) 的点击消息框样式 : openInfoWindow,如下:

function createMarkder(point, title, addr) {
    var opts = {
        title : '附近搜索'
    };
    var msg = '<p style="margin:5px 0;">名称: '+ title + '</p>';
    msg += '<p style="margin:5px 0;">地址: ' + addr + '</p>';
    
    msg += '<p style="margin:5px 0;"> 查找范围 <input type="text" id="disbox" value="500" style="width:45px;" /> 米;</p>';
    msg += '<p style="text-align:right;margin:5px 0;"> <button type="button" onclick="searCars(\''+point.lng+','+point.lat+'\');">车辆查找</button>&nbsp;<button type="button" onclick="searPeos(\''+point.lng+','+point.lat+'\');">人员查找</button> </p>';
    ZMap.msgAlert(opts, msg, ZMap.mapObj, point);

}

查看上图中,地图上的消息框样式;

4. 车辆查询及人员查找 方法;

function searCars(poi) {
    $('#tyspn').html('车辆查询');
    listAndEvts('CAR', poi);
}

function searPeos(poi) {
    $('#tyspn').html('人员查询');
    listAndEvts('PEO', poi);
}

function listAndEvts(ty, poi) {
    var distance = parseInt($('#disbox').val());
    var point = ZMap.getPoint(poi);
    
    cs.set({
        distance: distance,
        point: point
    });
    
    var res = cs.search((ty == 'CAR') ? cars : peos);
    var img = (ty == 'CAR') ? '/images/gis/car.png' : '/images/gis/peo.png';
    var info = (ty == 'CAR') ? '闽 C 4587' : '小王';
    
    var reList = '';
    for (itm in res) {
        if (res[itm] instanceof BMap.Point) {
            reList += '<p style="margin:3px 0; cursor: pointer; clear:both;" sign="'+ty+'" lnglat="'+poi+'"><img src="'+img+'" width="24" height="24" align="absmiddle" /> '+info+''+itm+' </p>';
        }
    }
    
    $('#resDiv').html(reList)
        .find('p')
            .click(function() {
                var sign = $(this).attr('sign');
                var lnglat = $(this).attr('lnglat');
                
                //createCmdWindow(sign, lnglat);
            });
}

cs 中心点附近查找方法 对象,已经在 脚本初始化时构建;

cs.set(opts): 用于配置,中心点,中心半径长度,是否标注符合结果等;

以上方法实现,车辆查找及人员查找在当前标注点附近一定距离内的查找,并使中间列标题根据查询类型切换,只是简单的模拟显示样例,像上面的 车或人员,有可能还得从 数据库 ajax 获取相关车牌号,人员姓名等信息;

cs.search(arrays); arrys就是上面全局 cars 及 peos 的模拟数据数组,并返回结果,是个 BMap.Point 的结果集合;
