使用高德地图JS获取当前位置和经纬度

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：

                var res = document.getElementById("result1");
                if(res && res['curSelect'] !== -1){
                    selectResult(document.getElementById("result1").curSelect);
                }
            }else{
                autoSearch();
            }
        }
    </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。
