先看效果，我做的是这样的，可以按地图位置来返回当前你点的位置(图一，二)，也可以根据输入框的自动搜索(图三，四)
HTML的代码：
<div> <input type="text" id="keyword" name="keyword" value="" onkeydown='keydown(event)'/> <div id="result1" name="result1"></div> <div>X：<input type="text" id="lngX" name="lngX" value=""/> <br> Y：<input type="text" id="latY" name="latY" value=""/> </div> </div> <div> <a id='open'>地图定位</a> </div>
JS代码：
<script type="text/javascript" src="http://webapi.amap.com/maps?v=1.3&key=您的Key值"></script>

基本就是这样了。直接拷贝就能用。能实现我一开始说的效果。
