我正在尝试设置一个 cookie,然后读取它并将其放入我的谷歌地理编码脚本中,但它似乎不起作用。应该是唯一的自动建议结果来自美国,但您可以在示例中看到它们是来自每个国家/地区的建议。
这是我正在使用的代码:

这是原始代码:
<script type="text/javascript" src="//maps.google.com/maps/api/js?sensor=true&libraries=places"></script>
<script type="text/javascript" src="https://raw.github.com/carhartl/jquery-cookie/master/jquery.cookie.js"></script>
<script type="text/javascript">
// SET COOKIE FOR TESTING
$.cookie("country", "us");
// GEOCODE RESULT
function geocode(){
var GeoCoded = { done: false };
var input = document.getElementById('loc');
var options = { types: []};
var country_code = $.cookie('country');
if (country_code) { options.componentRestrictions= { 'country': country_code }; }
var autocomplete = new google.maps.places.Autocomplete(input, options);
$('#searchform').on('submit',function(e){
if(GeoCoded.done)
return true;
e.preventDefault();
var geocoder = new google.maps.Geocoder();
var address = document.getElementById('loc').value;
$('#searchform input[type="submit"]').attr('disabled',true);
geocoder.geocode({
'address': address
},
function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
$('#lat').val(results[0].geometry.location.lat());
$('#lng').val(results[0].geometry.location.lng());
GeoCoded.done = true;
$('#searchform').submit();
} else {
$('#searchform input[type="submit"]').attr('disabled',false);
alert("Damn! We couldn't find this location")
}
});
});
};
</script>
<body onload="geocode()">
<form name="searchform">
<input class="kw" id="keyword" placeholder="Keyword"></input>
<input id="loc" placeholder="Location" type="text"></input>
<input type="submit" value="Search" id="search">
<input class="hidden" id="lat" disabled="true" placeholder="lat"></input>
<input class="hidden" id="lng" disabled="true" placeholder="lng"></input>
</form>
