百度地图poi搜索框

1：初始化地图

var map = new BMap.Map("container");//初始化地图
point = new BMap.Point(126.65771686, 45.77322463);
////初始化地图中心点
map.centerAndZoom(point, 10);
//启用滚轮放大缩小   默认禁用
map.enableScrollWheelZoom();   
//启用地图惯性拖拽   默认禁用
map.enableContinuousZoom(); 

//添加搜索框 步骤2

2：添加搜索框

 // 创建控件
    var myZoomCtrl = new ZoomControl();
    // 添加到地图当中
    map.addControl(myZoomCtrl);


    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;
        $("#searchResultPanel").innerHTML = str;
    });

    var myValue;
    ac.addEventListener("onconfirm", function(e) {    //鼠标点击下拉列表后的事件
        debugger;    
    var _value = e.item.value;
        myValue = _value.province +  _value.city +  _value.district +  _value.street +  _value.business;
        $("#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, 14);
            marker=new BMap.Marker(pp)
            map.addOverlay(marker);    //添加标注
        }
        var local = new BMap.LocalSearch(map, { //智能搜索
          onSearchComplete: myFun
        });
        local.search(myValue);
    }
