集成Google地图搜索框和搜索地点

Question

我正在尝试添加Google地图搜索框。但似乎我无法在我的代码中使其工作。

我一直在使用此thread作为参考，但我无法在代码中使用它。这是我要添加搜索框的代码。我也一直在互联网上寻求更多参考，但我无法使其发挥作用。我希望有人可以帮我解决我的问题。

$(document).ready(function() {

var mapCenter = new google.maps.LatLng(9.122192499999999, 125.53760299999999); //Google map Coordinates
var map;


map_initialize(); // initialize google map

//############### Google Map Initialize ##############
function map_initialize()
{
        var googleMapOptions = 
        { 
            center: mapCenter, // map center
            zoom: 17, //zoom level, 0 = earth view to higher value
            maxZoom: 18,
            minZoom: 14,
            zoomControlOptions: {
            style: google.maps.ZoomControlStyle.SMALL //zoom control size
        },
            scaleControl: true, // enable scale control
            mapTypeId: google.maps.MapTypeId.ROADMAP // google map type
        };

        map = new google.maps.Map(document.getElementById("google_map"), googleMapOptions);         

        //Load Markers from the XML File, Check (map_process.php)
        $.get("map_process.php", function (data) {

我想在输入地址时添加搜索框和搜索位置。
