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="http://www.mamicode.com/‘+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);                    ZMap.events.add(‘searByAddr_marker‘, marker, ‘click‘, function(e) {                        createMarkder(point, title, addr);                    });                })(poi.point, poi.title, poi.address, i);                */            }                        $(addrs.join(‘‘)).appendTo($(‘#cartable table‘));                        $(‘#cartable table tbody‘).find(‘tr‘).click(function() {                $(this).parent().find(‘tr‘).each(function() {                    var oricls = $(this).attr(‘oricls‘);                    $(this).attr(‘class‘, oricls);                }) ;                                var oris = $(this).attr(‘oricls‘);                $(this).attr(‘class‘, oris + ‘ selected‘);                                //title                var title = $(this).find(‘td:eq(1)‘).find(‘span:eq(0)‘).html();                //addr                var addr = $(this).find(‘td:eq(1)‘).find(‘span:eq(1)‘).html();                //point                var point = ZMap.getPoint($(this).find(‘td:eq(0)‘).find(‘input‘).val());                                createMarkder(point, title, addr);            });        },        markercall : function(pois) {            var cloneArr = pois.slice(0);                        //ZMap.clear();                        for (var i=0;i<cloneArr.length;i++) {                var marker = pois[i].marker;// ZMap.labelMarker((i+1), cloneArr[i].point);//                console.log(cloneArr[i].title+‘-‘+cloneArr[i].address+‘-‘+cloneArr[i].point.lng+‘-‘+cloneArr[i].point.lat)                var title = cloneArr[i].title;                var address = cloneArr[i].address;                var point = cloneArr[i].point;                                (function(point, title, addr, n) {                    var marker = ZMap.labelMarker((n+1), point);                    ZMap.events.add(‘searByAddr_marker‘+i, marker, ‘click‘, function(e) {                        createMarkder(point, title, addr);                    });                })(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="http://www.mamicode.com/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);}

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="http://www.mamicode.com/‘+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;
