谷歌地理编码器问题

我正在尝试对用户在文本字段中给出的地址进行地理编码，但是我的 JavaScript 函数不会从“geocoder.geocode ({'address':address......” ) 行开始执行。

我被困在这里不知道为什么它不起作用。它会抛出第一个警告框，显示地址字段已移至客户端脚本，但之后就不起作用了，请让我知道我需要在哪里进行更正。是客户端代码。

var map;
var geocoder;
function initialize()
{
    geocoder = new google.maps.Geocoder();  
}
function getgeocode() {  
    var address = document.advpollsrch.txtaddress.value;
    alert(address);
    geocoder.geocode( {'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            alert("Geocode was successful");
            var latlng = results[0].geometry.location;
            document.advpollsrch.hidlatitude.value = latlng.lat();
            document.advpollsrch.hidlongitude.value = latlng.lng();
            alert("Geocode split was successful");
            return true;
        } else {
            alert("Geocode was not successful for the following reason: " + status);
            return false;
        }
    });
}  
<body onload="initialize()">
    <form  name="advpollsrch"> <!-- onsubmit="return getgeocode()" -->
        <input type="hidden" name="hidlatitude" id="hidlatitude"></input>
        <input type="hidden" name="hidlongitude" id="hidlongitude"></input>

原文

I am trying to geocode an address given by the user in the text field, however my JavaScript function does not execute from the line "geocoder.geocode ({'address':address......" onwards.

I am stuck here not sure why it doesn't work. It throws thee first alert box showing the address field pulled over to the client script but does not work after that. It just stays without any action. Please let me know where i need to correct. Here is the client side code.

var map;
var geocoder;
function initialize()
{
    geocoder = new google.maps.Geocoder();  
}
function getgeocode() {  
    var address = document.advpollsrch.txtaddress.value;
    alert(address);
    geocoder.geocode( {'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            alert("Geocode was successful");
            var latlng = results[0].geometry.location;
            document.advpollsrch.hidlatitude.value = latlng.lat();
            document.advpollsrch.hidlongitude.value = latlng.lng();
            alert("Geocode split was successful");
            return true;
        } else {
            alert("Geocode was not successful for the following reason: " + status);
            return false;
        }
    });
}  
<body onload="initialize()">
    <form  name="advpollsrch"> <!-- onsubmit="return getgeocode()" -->
        <input type="hidden" name="hidlatitude" id="hidlatitude"></input>
        <input type="hidden" name="hidlongitude" id="hidlongitude"></input>
