问如何在Google Maps V3 API中构建类似的内容？

EN

var address = $("#id_address_input").val();
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
    $("#badlocation_holder").hide();
    $("#map_canvas").show();
    $("#map_canvas_holder").show().css("background-color", "#E6E6FA").animate({"background-color":"#f5f5f5"}, 800);
    var myOptions = {
        zoom: 15,
        center: results[0].geometry.location,
        streetViewControl:false,
        mapTypeControl:false,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        scrollwheel:false,
    };

    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);  
    var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location,
            draggable:true
    });
