[百度地图] 用于类似 DWZ UI 框架的 百度地图 功能封装类 [MultiZMap.js] 实例源码

MultiZMap 功能说明

MultiZMap.js 本类方法功能大多使用 prototype 原型 实现，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；

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；

*/

console && console.log('In MultiZMap!');

function MultiZMap(opts) {
this.mapId = opts.mapId || 'mapId';
this.container = opts.container || 'container';
this.level = opts.level || 12;
this.lng = opts.lng;
this.lat = opts.lat;
this.addr = opts.addr;
this.callback = opts.callback;
this.mapObj = null;

var me = this;
this.enables = {
scrollWheel: function() {
me.mapObj.enableScrollWheelZoom();
}
};

this.disables = {
doubleClkZoom : function() {
me.mapObj.disableDoubleClickZoom();
}
};

this.controls = {
addNavi : function(opts) {
me.mapObj.addControl(new BMap.NavigationControl(opts));
},
addScale : function(opts) {
me.mapObj.addControl(new BMap.ScaleControl(opts));
},
addOverview : function(opts) {
me.mapObj.addControl(new BMap.OverviewMapControl(opts));
},
addMapType : function(opts) {
me.mapObj.addControl(new BMap.MapTypeControl(opts));
},
addGeolocation : function(opts) { //mobi
try {
me.mapObj.addControl(new BMap.GeolocationControl(opts));
}catch(e) {}
}
};
};

MultiZMap.defaults = {
city : '泉州',
level: 12
};

2. 创建加载地图:

MultiZMap.prototype.create = function() {
var me = this;
me.mapObj = new BMap.Map(me.mapId);

if (me.lng && me.lat) {
var point = new BMap.Point(me.lng, me.lat);
me.mapObj.centerAndZoom(point, me.level);
} else if(me.addr){
me.mapObj.centerAndZoom(me.addr, me.level);
} else {
me.mapObj.centerAndZoom(MultiZMap.defaults.city, me.level);
}

me.callback && me.callback();

setTimeout(function() { //删除版权
$('#'+me.mapId).find('.anchorBL').remove();
}, 1000);

};

3. 使用方法:

var multiMap = new MultiZMap({
mapId: 'mapId',
container : 'container',
lng: 116.404,
lat: 39.915,
level: 15,
callback: function() {
//
}
});
multiMap.create();

4. html 代码样例:

1> 引用脚本:

<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> 地图容器块:

<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="mapId" style="width:100%; height:640px;"></div>
</div>

上面地图创建实例说明:

mapId: 为地图容器;

container: 为地图辅助容器，内嵌一个 panel div，用于全屏，或打印时显示关闭及打印按钮；

callback: 为地图加载后的回调方法；

MultiZMap 部分辅助功能

1. dom 原生操作块:

MultiZMap.dom = {
getE: function(eleId) {
return document.getElementById(eleId);
},
newE : function(eleId) {
var _ele = MultiZMap.dom.getE(eleId);
if (_ele) {
return _ele;
}

var ele = document.createElement('div');
MultiZMap.dom.set(ele, 'id', eleId);
return ele;
},
after : function(newE, targetE) {
targetE.parentNode.lastChild == targetE ? targetE.parentNode.appendChild(newE) : targetE.parentNode.insertBefore(newE, targetE.nextSibling);
},
set : function(target,attr,val) {
target.setAttribute(attr, val);
},
remove: function(target) {
target.parentNode.removeChild(target);
},
getEbyCls : function(clsName, tagName) {
var ClassElements = [];
selElements = document.getElementsByTagName(tagName);

for (var i = 0; i < selElements.length; i++) {
if (selElements[i].className == clsName) {
ClassElements[ClassElements.length] = selElements[i];
}
}
return ClassElements;
}
};

2. 事件处理方法块:

MultiZMap.prototype.addListener = function(type,callback) {
MultiZMap.events.add('Main', this.mapObj, type, callback);
};

/**
* 1. add => key: method_objName[x]
* eg: GuiJiPlay_polyline
* 2. ZMap.mapObj => key: Main
* 3. caches => key : method_objName[x]_type || Main_type
*/
MultiZMap.events = {
caches : {},
add : function(key,obj,type,callback) {
obj.addEventListener(type, callback);
this.caches[key+'_'+type] = {'obj':obj, 'type':type, 'callback':callback};
},
remove : function(key, type) {
this.removeByKey(key+'_'+type);
},
removeByKey : function(keytype) {
if (this.caches[key]) {
var json = this.caches[keytype];
json['obj'] && json['obj'].removeEventListener(json['type'], json['callback']);

delete this.caches[key];
}
},
clear : function () {
for (keytype in this.caches) {
this.removeByKey(keytype);
}

this.caches = {};
}
};

MultiZMap 部分功能实例

1. 轨迹回放功能:

/**
* 轨迹回放
* @param opts
* @returns {ZMap.GuiJiPlay}
*/

MultiZMap.prototype.GuiJiPlay = function(multiMap, opts) {

opts = opts || {};
this.points = [];
this.centerPoint = null;
this.index = 0;
this.timer = null;
this.polyline = null;
this.runlines = [];
this.speed = 1000;
this.isplay = false;
this.multiMap = multiMap;

this.potlen = 0;
this.marker = {
marker : null,
label: '',
icon: {
width: 50,
height: 50
}
};

if (opts.label && opts.label != '') {
this.marker.label = opts.label;
}

if (opts.icon) {
this.marker.icon = opts.icon;
}
};

MultiZMap.prototype.GuiJiPlay.prototype.set = function(pointArr) {
var me = this;

me.points = [];
for (itm in pointArr) {
var one = pointArr[itm];

if (typeof one != "string")
continue;

var point = me.multiMap.getPoint(one);

if (point && point instanceof BMap.Point) {
me.points.push(point);
}
}

me.potlen = me.points.length;

me.init();
};

MultiZMap.prototype.GuiJiPlay.prototype.init = function() {
var me = this;
me.clear();

me.centerPoint = new BMap.Point((me.points[0].lng + me.points[me.potlen - 1].lng) / 2, (me.points[0].lat + me.points[me.potlen - 1].lat) / 2);
me.multiMap.mapObj.panTo(me.centerPoint);

me.polyline = new BMap.Polyline(me.points, {strokeColor: "blue", strokeWeight: 5, strokeOpacity: 1});
me.multiMap.mapObj.addOverlay(me.polyline);

if (!me.marker.icon) {
me.marker.marker = me.multiMap.iconMarker(me.marker.icon, me.points[0]);
} else if (me.marker.label != '') {
me.marker.marker = me.multiMap.labelMarker(me.marker.label, me.points[0]);
} else {
me.marker.marker = me.multiMap.marker(me.points[0]);
}

};

MultiZMap.prototype.GuiJiPlay.prototype.reset = function() {
var me = this;
me.index = 0;
if (me.marker.marker && me.points.length > 0) {
me.marker.marker.setPosition(me.points[0]);
}

me.pause();
};

MultiZMap.prototype.GuiJiPlay.prototype.clear = function() {

var me = this;
if (me.polyline) {
me.multiMap.mapObj.removeOverlay(me.polyline);
}

me.clearStepline();
me.polyline = null;
me.runlines = [];
me.reset();
};

MultiZMap.prototype.GuiJiPlay.prototype.clearStepline = function() {
var me = this;
for (itm in me.runlines) {
var line = me.runlines[itm];
if (line instanceof BMap.Polyline) {
me.multiMap.mapObj.removeOverlay(line);
}

}
};

MultiZMap.prototype.GuiJiPlay.prototype.play = function(speed) {
var me = this;
if (speed)
me.speed = speed;

if (!me.isplay) {
me.clearStepline();
me.isplay = true;
}

var point = me.points[me.index];

if(me.index > 0) {
var cline = new BMap.Polyline([me.points[me.index - 1], point], {strokeColor: "red", strokeWeight: 1, strokeOpacity: 1});
me.multiMap.mapObj.addOverlay(cline);
me.runlines.push(cline);
}

me.marker.marker.setPosition(point);
me.index++;
if(true) {
me.multiMap.mapObj.panTo(point);
}
if(me.index < me.points.length) {
me.timer = window.setTimeout(function() {
me.play();
}, me.speed);
} else {
me.multiMap.mapObj.panTo(point);
}
};

MultiZMap.prototype.GuiJiPlay.prototype.pause = function() {
var me = this;
if(me.timer) {
window.clearTimeout(me.timer);
}
me.timer = null;
me.isplay = false;
};

使用方法:

var guiji ;
function guiJiMap() {
guiji = new multiMap.GuiJiPlay(multiMap, {
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);
}

MultiZMap 版本, 需要传入当前 MultiZMap 的对象，用于在功能中获取 mapObj地图对象等，以及其他的一些方法；

执行回放: guiji.play(); 暂停: guiji.pause(); 重置: guiji.reset();

2.1. 地图全屏 <1> [可使用于 非嵌入iframes 或 复杂结构]:

/**
* 地图全屏
* @param opts
* @returns {ZMap.fullMap}
*/
MultiZMap.prototype.fullMap = function(multiMap, opts) {
this.width = opts.width || 700;
this.height = opts.height || 640;
//    this.container = opts.container;
//    this.mapId = opts.mapId;
this.fullfunc = opts.fullfunc;
this.origifunc = opts.origifunc;
this.multiMap = multiMap;
};

MultiZMap.prototype.fullMap.prototype.toFull = function() {
var me = this;

var _width = $(window).width();
var _height = $(window).height();
var posi = $('#'+me.multiMap.container).css('position');

if (posi != 'absolute') {
$('#'+me.multiMap.container).css({
position:'absolute',
width: _width + 'px',
height: _height + 'px',
top : '0px',
left : '0px'
});

$('#'+me.multiMap.mapId).css('height', '100%');

me.multiMap.mapObj.width = _width;
me.multiMap.mapObj.height = _height;

me.multiMap.mapObj.reset();

me.fullfunc && me.fullfunc();
}
};

MultiZMap.prototype.fullMap.prototype.toOrigi = function() {
var me = this;
var posi = $('#'+me.multiMap.container).css('position');

if (posi == 'absolute') {
$('#'+me.multiMap.container).css({
position:'relative',
width: me.width + 'px',
height: me.height + 'px'
});

$('#'+me.multiMap.mapId).css('height', me.height + 'px');

me.multiMap.mapObj.width = me.width;
me.multiMap.mapObj.height = me.height;

me.multiMap.mapObj.reset();

me.origifunc && me.origifunc();
}
};

this.container 用来设置 容器 , 即上面的 div#container; this.mapId即是地图容器id div#mapId;

使用方法:

var fullmap;
function fullMap() {
fullmap = new multiMap.fullMap(multiMap, {
container : 'container',
mapId : 'mapId',
fullfunc : function() {
$('#panel').css('display','block');
},
origifunc : function() {
$('#panel').css('display','none');
}
});

fullmap.toFull();
}

panel 的 X span 设置click 事件 :

$('#panel span').click(function() {
fullmap.toOrigi();
});

2.2, 地图全屏 <2> [可用于任何 html 结构]

/**
* 地图全屏 append 方式 [For Like Dwz MultiTabs UI]
* @multiMap
* @returns {ZMap.XfullMap}
*/
MultiZMap.prototype.XfullMap = function(multiMap, opts) {
this.width = opts.width || 700;
this.height = opts.height || 640;
this.fullfunc = opts.fullfunc;
this.origifunc = opts.origifunc;
this.multiMap = multiMap;
this.fullId = 'Full_'+multiMap.container;
};

MultiZMap.prototype.XfullMap.prototype.toFull = function(point) {
var me = this;
var _width = $(window).width();
var _height = $(window).height();

var fullMapObj = $('#'+me.fullId);

if (fullMapObj.length == 0) {
$("<div id='"+me.fullId+"'>")
.css({
position:'absolute',
width: _width + 'px',
height: _height + 'px',
top : '0px',
left : '0px'
})
.appendTo('body');

fullMapObj = $('#'+me.fullId);
}

fullMapObj.show();

fullMapObj.append($('#'+me.multiMap.container).children());

$('#'+me.multiMap.mapId).css('height', '100%');

me.multiMap.mapObj.width = _width;
me.multiMap.mapObj.height = _height;

me.multiMap.mapObj.reset();

me.multiMap.panTo(point);

me.fullfunc && me.fullfunc();
};

MultiZMap.prototype.XfullMap.prototype.toOrigi = function(point) {
var me = this;
var fullMapObj = $('#'+me.fullId);

if (fullMapObj.length > 0) {
$('#'+me.multiMap.container).append(fullMapObj.children());
fullMapObj.hide();
}

$('#'+me.multiMap.mapId).css('height', me.height + 'px');

me.multiMap.mapObj.width = me.width;
me.multiMap.mapObj.height = me.height;

me.multiMap.mapObj.reset();

me.origifunc && me.origifunc();

me.multiMap.panTo(point);
};

使用方法:

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

fullmap.toFull();
}

使用方法与第一种方式，一模一样；

3. 公交方案, 途经点:

/***
* 公交方案, 途经点
* @returns {ZMap.crossPointTraffic}
*/
MultiZMap.prototype.crossPointTraffic = function(multiMap, opts) {
this.driving = new BMap.DrivingRoute(multiMap.mapObj, {renderOptions:{enableDragging: true,autoViewport: true}}); //renderOptions 下 map 会出现 起点,终点图标
this.start = opts.start;
this.end = opts.end;
this.pass = opts.pass;
this.icon = opts.icon;
this.mkrType = opts.type || 'Label';
this.polylines = [];
this.multiMap = multiMap;

this.init();
};

MultiZMap.prototype.crossPointTraffic.prototype.init = function() {
var me = this;

//me.reset();

me.driving.setSearchCompleteCallback(function() {
var pts = me.driving.getResults().getPlan(0).getRoute(0).getPath();
var polyline = new BMap.Polyline(pts);

me.polylines.push(polyline);
me.multiMap.mapObj.addOverlay(polyline);

var potEnd = pts[pts.length - 1];
if (me.start && me.end) {
me.mkrType == 'Label' ? me.multiMap.labelMarker(me.icon.start, pts[0]) : me.multiMap.iconMarker(me.icon.start, pts[0]);
me.mkrType == 'Label' ? me.multiMap.labelMarker(me.icon.end, potEnd) : me.multiMap.iconMarker(me.icon.end, potEnd);
} else {
if (me.start) {
me.mkrType == 'Label' ? me.multiMap.labelMarker(me.icon.start, pts[0]) : me.multiMap.iconMarker(me.icon.start, pts[0]);
me.mkrType == 'Label' ? me.multiMap.labelMarker(me.icon.pass, potEnd) : me.multiMap.iconMarker(me.icon.pass, potEnd);
} else if (me.pass) {
me.mkrType == 'Label' ? me.multiMap.labelMarker(me.icon.pass, potEnd) : me.multiMap.iconMarker(me.icon.pass, potEnd);
} else {
me.mkrType == 'Label' ? me.multiMap.labelMarker(me.icon.end, potEnd) : me.multiMap.iconMarker(me.icon.end, potEnd);
}

}
});
};

MultiZMap.prototype.crossPointTraffic.prototype.reset = function() {
var me = this;
if (me.polylines.length > 0) {
for (itm in me.polylines){
var line = me.polylines[itm];
me.multiMap.mapObj.removeOverlay(line);
}

me.polylines = [];
};
me.start = false;
me.pass = false;
me.end = false;
};

MultiZMap.prototype.crossPointTraffic.prototype.search = function(start, end) {
var me = this;
me.driving.search(start, end);
};

使用方法:

function crossPointMap() {
var addrs = ["天安门", "三里屯", "百度大厦"];

multiMap.centerCity("北京市", 15);

var drlen = addrs.length;
for (var i=0;i<drlen;i++) {
if (i==0) {
continue;
}

var opts = {};
if (drlen == 2) {
opts.start = true;
opts.end = true;
} else {
if ((i-1) == 0) {
opts.start = true;
}
else if (i == (drlen-1)) {
opts.end = true;
}else {
opts.pass = true;
}
}

opts.icon = {};
opts.icon.start = '起点';
opts.icon.end = '终点';
opts.icon.pass = '途经点';

var drive = new multiMap.crossPointTraffic(multiMap, opts);
drive.search(addrs[i-1], addrs[i]);

multiMap.enables.scrollWheel();

}
}

三里屯,就是要经过的点;
