 */
function keySearch(){
    AMap.plugin('AMap.Autocomplete', function(){
        var mapSearch = new AMap.Autocomplete({
            input: "mapSearch",
        });
        AMap.event.addListener(mapSearch, "select", keySearchSelect);//注册监听，当选
    });
}
/**

 */
function keySearchSelect(result){
    {
        "type": "select",
        "poi": {
