前端调用百度地图api实现地图功能

有时候网站需要地图功能，div+css5的小编给大家介绍一下如何实现网站地图功能：

<!DOCTYPE html>
<html>

<head>
<meta charset="UTF-8">
<title></title>
<script src="http://api.map.baidu.com/api?v=2.0&ak=W1a6ywZFkybedSCHadpRbkz4w5HYfG4R" type="text/javascript" charset="utf-8"></script>
<style type="text/css">
* {
margin: 0;
padding: 0;
}

html,
body {
width: 100%;
height: 100%;
position: relative;
}

h3 {
display: block;
width: 100%;
height: 60px;
line-height: 60px;
text-align: center;
background: aquamarine;
color: #fff;
font-size: 40px;
}

#allmap {
width: 100%;
height: 700px;
}
#r-result{
position: absolute;
left: 0;
top: 100px;
background: #000;
color: #fff;
}
</style>
</head>

<body>
<h3>我的地图</h3>
<div id="allmap"></div>
<div id="r-result">请输入:<input type="text" id="suggestId" size="20" value="百度" style="width:150px;" /></div>
<div id="searchResultPanel" style="border:1px solid #C0C0C0;width:150px;height:auto; display:none;"></div>
<script type="text/javascript">
var map = new BMap.Map("allmap");
map.centerAndZoom("郑州", 15); // 初始化地图,设置中心点坐标和地图级别
map.addControl(new BMap.MapTypeControl()); //添加地图类型控件
map.setCurrentCity("北京"); // 设置地图显示的城市此项是必须设置的
map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放
function G(id) {
return document.getElementById(id);
}
var ac = new BMap.Autocomplete( //建立一个自动完成的对象
{
"input": "suggestId",
"location": map
});

ac.addEventListener("onhighlight", function(e) { //鼠标放在下拉列表上的事件
var str = "";
var _value = e.fromitem.value;
var value = "";
if(e.fromitem.index > -1) {
value = _value.province + _value.city + _value.district + _value.street + _value.business;
}
str = "FromItem<br />index = " + e.fromitem.index + "<br />value = " + value;

value = "";
if(e.toitem.index > -1) {
_value = e.toitem.value;
value = _value.province + _value.city + _value.district + _value.street + _value.business;
}
str += "<br />ToItem<br />index = " + e.toitem.index + "<br />value = " + value;
G("searchResultPanel").innerHTML = str;
});

var myValue;
ac.addEventListener("onconfirm", function(e) { //鼠标点击下拉列表后的事件
var _value = e.item.value;
myValue = _value.province + _value.city + _value.district + _value.street + _value.business;
G("searchResultPanel").innerHTML = "onconfirm<br />index = " + e.item.index + "<br />myValue = " + myValue;

setPlace();
});

function setPlace() {
map.clearOverlays(); //清除地图上所有覆盖物
function myFun() {
var pp = local.getResults().getPoi(0).point; //获取第一个智能搜索的结果
map.centerAndZoom(pp, 18);
map.addOverlay(new BMap.Marker(pp)); //添加标注
}
var local = new BMap.LocalSearch(map, { //智能搜索
onSearchComplete: myFun
});
local.search(myValue);
}
