一.首先引入所申请的ak密钥
<script type="text/javascript" src="http://wx.58haha.cn/baidu/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="http://api.map.baidu.com/api?ak=PlhFWpA02aoURjAOpnWcRGqw7AI8EEyO&v=2.0&services=false"></script>
二.简单样式处理一下
body, html {width: 100%;height: 100%; margin:0; padding:0; font-family:"微软雅黑";}
#l-map{height: 220px;width:100%;}
#r-result,#r-result table{width:100%;}
.nav { width: 100%; height: 2em; line-height: 2em; background: #EDEDED; border: 1px solid #ADADAD;}
.nav .nav-inner{ width: 30%; margin-left: 35%;}
.nav .nav-sub { float: left; width: 33%;}
.nav .nav-sub a { text-decoration: none; }
.nav .nav-sub a i { display: inline-block; background: url("http://webmap1.map.bdstatic.com/wolfman/static/common/images/ui3/mo_banner_ba37b5d.png")}
.nav .nav-sub a.bus i { background-position: -1px -192px; position: relative; top: 2px; width: 13px; height: 16px;}
.nav .nav-sub a.driver i { background-position: -29px -194px; width: 15px; height: 14px;}
.nav .nav-sub a.walk i { background-position: -102px -189px; width: 16px; height: 18px;}
.nav .nav-sub a.bus.cur i { background-position: -15px -192px; }
.nav .nav-sub a.driver.cur i { background-position: -45px -194px; }
.nav .nav-sub a.walk.cur i { background-position: -120px -189px;}
.hide { display: none;}
input { font-family: "micrsoft yahei"; width: 100%; height: 2em; font-size: 1em; line-height: 2em; border: 0px; outline: 0px; padding: .2em 1em; }
.btn-group { width: 100%; border-top: 1px solid #DDD; border-bottom: 2px solid #DDD;}
button {width: 32%; text-align: center; border: 0; border-radius: 0; background-color: inherit; height: 44px; line-height: 44px; font-size: 15px;}
三.html代码布局
<div id="search">
<input type="text" id="start" placeholder="正在定位您的位置..." style="border-bottom: 1px solid #DDD; " />
<input type="text" id="end" value="金海商富中心" readonly="true" />
<input type="hidden" id="start_point" value=""/>
<input type="hidden" id="end_point" value="116.501573,39.900877"/>
<input type="hidden" id="start_location" value=""/>
<div class="btn-group">
<button id="bus-search">公交</button>
<button id="driver-search">驾车</button>
<button id="walk-search">步行</button>
</div>
</div>
<div id="showMap" class="hide">
<div class="nav">
<div class="nav-inner">
<div class="nav-sub"><a href="#" class="bus"><i></i></a></div>
<div class="nav-sub"><a href="#" class="driver cur"><i></i></a></div>
<div class="nav-sub"><a href="#" class="walk"><i></i></a></div>
</div>
<!-- <a href="javascript:;" id="reLocation">重新导航</a> -->
</div>
<div id="l-map"></div>
<div id="r-result"></div>
</div>
四.js代码如下
$(function(){
//获取目的地的经纬度--转为一维数组
var ep = $("#end_point").val().split(",");
//实例化地图
var map = new BMap.Map("l-map");
//设置中心点坐标
var point = new BMap.Point(ep[0], ep[1]);
//初始化地图
map.centerAndZoom(point, 16);
// 定位对象
var geoc = new BMap.Geocoder();
var geolocation = new BMap.Geolocation();
geolocation.getCurrentPosition(function(r){
if(this.getStatus() == BMAP_STATUS_SUCCESS){
var mk = new BMap.Marker(r.point);
map.addOverlay(mk);
map.panTo(r.point);
$("#start_point").val(r.point.lng+','+r.point.lat);
setLocation(r.point);
showMap();
}else {
$("#start").attr("placeholder","请输入您的当前位置")
alert('无法定位到您的当前位置，导航失败，请手动输入您的当前位置！'+this.getStatus());
}
},{enableHighAccuracy: true});
//交通方式切换
$(".nav .nav-sub a").click(function(){
$(".nav .nav-sub a").removeClass('cur');
$(this).addClass('cur');
searchRoute();
})
//重新定位
$("#reLocation").click(function(){
reLocation();
});
//点击不同的交通方式时,当前的高亮显示
$("#bus-search,#driver-search,#walk-search").click(function(){
var id = $(this).attr("id");
$(".nav .nav-sub a").removeClass('cur');
if(id == "bus-search"){
$(".nav .nav-sub a.bus").addClass('cur');
}else if(id == "driver-search"){
$(".nav .nav-sub a.driver").addClass('cur');
}else if(id == "walk-search"){
$(".nav .nav-sub a.walk").addClass('cur');
}
showMap();
})
//重新定位--重新载入地图
function reLocation(){
$("#search").show();
$("#showMap").hide();
map = new BMap.Map("l-map");
}
//显示地图
function showMap(){
$("#srarch").hide();
$("#showMap").show();
searchRoute();
}
//设置位置
function setLocation(point){
geoc.getLocation(point, function(rs){
console.log(rs);
var addComp = rs.addressComponents;
var result = addComp.province + addComp.city + addComp.district + addComp.street + addComp.streetNumber;
$("#start").val(result);
$("#start_location").val(result);
searchRoute();
});
}
//交通方式检索---交通的结果
function searchRoute(s_, e_){
map = new BMap.Map("l-map");
var cur = $(".nav .nav-sub a.cur");
var type = "";
if(cur.hasClass('bus')){
type = "bus";
}else if(cur.hasClass('driver')){
type = "driver";
}else if(cur.hasClass('walk')){
type = "walk";
}else{
type = "driver";
}
var s_;
var e_;
var sl = $("#start_location").val();
var s = $("#start").val();
var sp = $("#start_point").val();
var e = $("#end").val();
var ep = $("#end_point").val();
if(s != sl){// 如果用户修改了地址（与定位的位置不一致）则使用地址搜索
s_ = s;
e_ = e;
}else if(sp){// 否则使用坐标搜索
var ps = sp.split(",");
var pe = ep.split(",");
s_ = new BMap.Point(ps[0], ps[1]);
e_ = new BMap.Point(pe[0], pe[1]);
}
if(type == "bus"){
var transit = new BMap.TransitRoute(map, {renderOptions: {map: map, panel: "r-result", autoViewport: true}});
transit.search(s_, e_);
}else if(type == "driver"){
var driving = new BMap.DrivingRoute(map, {renderOptions: {map: map, panel: "r-result", autoViewport: true}});
driving.search(s_, e_);
}else if(type == "walk"){
var walking = new BMap.WalkingRoute(map, {renderOptions: {map: map, panel: "r-result", autoViewport: true}});
walking.search(s_, e_);
}
}
});
