    <style>

        #mapBox{height:400px;width:600px}
        #pointBox{height:20px;width:600px;}
    </style>
<body>
<div>
    <input id="addressBox" type="text" value="请输入结构化地址，例如无锡市" />
    <input id="" type="button" onclick="geocoder();" value="搜索" />
</div>
<div id='pointBox'> </div>
<div id='mapBox'></div>
<div>
使用方法：<br />
1.输入地址，点击搜索<br />
2.如果不够准确，可以拖动地图改变经纬度
</div>
<script type="text/javascript">
var $addressBox = document.getElementById('addressBox');
var $pointBox = document.getElementById("pointBox");

//创建地图 center是地图默认打开时候 定位显示的位置 这里是无锡市
var map = new AMap.Map("mapBox", {
    resizeEnable: true,
    center: [116.397428, 39.90923],
    zoom:14
});

//添加标注
function addMarker(point) {
    var marker = new AMap.Marker({
        map: map,
        position: [ point.getLng(),  point.getLat()]
    });
}

//地图中心点添加标注
//如果要给父窗口传值 则这里写
function addCenterPoint(){
    map.clearMap();
    var centerPoint = map.getCenter();
    addMarker(centerPoint);
    $pointBox.innerHTML = "当前经纬度为：" + centerPoint.getLng() + ',' + centerPoint.getLat();
  //给父窗口空间传值 txt10是父窗口Input的ID的值
  var k = window.opener;
  k.document.getElementById("txt10").value ="";
}
addCenterPoint();

function geocoder() {
    map.clearMap();
    var myGeo = new AMap.Geocoder();
    //地理编码,返回地理编码结果
    myGeo.getLocation($addressBox.value, function(status, result) {
        if (status === 'complete' && result.info === 'OK') {
            //地址解析成功
            geocoder_CallBack(result);
        }
        else{
            //地址解析失败
            $pointBox.innerHTML = "查无此地址";
        }
    });
}

//地理编码返回结果展示
function geocoder_CallBack(data) {
    var resultStr = "";
    var geocode = data.geocodes;
    addMarker(geocode[0].location);
    resultStr += "当前坐标</b>：" + geocode[0].location.getLng() + ", " + geocode[0].location.getLat();
    map.setFitView();
    $pointBox.innerHTML = resultStr;
}

map.on('moveend', function() {
    addCenterPoint();
});
