Javascript 谷歌地图自动完成时，点击按钮获取面积

为了得到与谷歌地图搜索栏相同的结果，我做了很多尝试。 我正在谷歌地图的搜索栏中使用以下代码

google.maps.event.addListener(autocomplete, 'place_changed', function() {
var place = autocomplete.getPlace();
    //alert(place.address_components.length);
     for (var i=0; i<place.address_components.length; i++) {
         for (var b=0;b<place.address_components[i].types.length;b++) {
            if (place.address_components[i].types[b] == "route") {
                    var route1= place.address_components[i];
                     route1 = route1.long_name;
                     undefined = true;
             }else if (place.address_components[i].types[b] == "sublocality") {
                  var   city1= place.address_components[i];
                     city1 = city1.long_name;
                     undefined = true;
             }else if (place.address_components[i].types[b] == "locality") {
                    var maincity= place.address_components[i];
                     maincity = maincity.long_name;
                     undefined = true;
             }else if (place.address_components[i].types[b] == "administrative_area_level_1") {
                    var state1= place.address_components[i];
                     state1 = state1.long_name;
                     undefined = true;
             }
         }
     }
});

google.maps.event.addListener（自动完成，'place\u changed'，function（）{
var place=autocomplete.getPlace（）；
//警报（位置、地址、组件、长度）；
对于（var i=0；i当您希望从autocomplete获取结果时，获取它们（并且不请求地理编码器），实际上我知道地址，如“德黑兰，伊朗”，然后我想点击按钮，然后我得到这个地址，并将地址地理编码为代码中的地址，但不会给出路线、位置、行政区域1级等相同的结果。。
 <div id="type-selector" class="controls"  onClick="search_click('sclick');" style="z-index: 2;position: absolute;top: -3px;">
    <label for="changetype-all">Search</label>    
 </div>

var get_add = document.getElementById("autocomplete").value;
var address = get_add;
geocoder = new google.maps.Geocoder();
            geocoder.geocode({
            'address': address
            }, function(results, status) {      
                var lat=results[0].geometry.location.lat();    
                var lng=results[0].geometry.location.lng(); 
var stockholm = new google.maps.LatLng(lat, lng);
 geocoder.geocode({'latLng': stockholm}, function(results, status) {
     if (status == google.maps.GeocoderStatus.OK) {
         //console.log(results);
         //alert(results[1]);
         //alert(results[0]);
         if (results[1]) {
             for (var i=0; i<results[1].address_components.length; i++) {
