百度地图API使用

1.引用js脚本

<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=1510247b4244370cbac3851e4f029d31"></script>

2.html控件

 <input type="text" id="suggestId" size="" data-bind="value:place" placeholder="请输入相关地址" class="wenb04" value="百度" />

 <div class="biaodan_r" id="l-map"></div>
                    <div id="searchResultPanel" style="border:1px solid #C0C0C0; height:auto; display:none;"></div>

3.document加载后，添加脚本

<script type="text/javascript">
    // 百度地图API功能
    function G(id) {
        return document.getElementById(id);
    }

    var map = new BMap.Map("l-map");
    map.centerAndZoom("深圳",);                   // 初始化地图,设置城市和地图级别。

    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 > -) {
            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 > -) {
            _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().point;    //获取第一个智能搜索的结果
            map.centerAndZoom(pp, );
            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);
    }
</script>
