我想向用户提供一个文本框，其中可以输入他们的地址。当他们输入地址时，会打开一个新窗口（Google地图）并自动填写Google地图中的搜索框。我想向用户提供他们尝试键入的地址的建议/预测。我还担心这个地址的相关性（例如，地址不是世界各地的地址）。
如何从其他网站的输入地址文本框中自动填充Google地图中的搜索框？
例如，在我的网站上，有一个文本框，我在该文本框中输入了一个地址，当我点击该文本框中的输入时，会出现一个新窗口并显示带有搜索栏的Google地图（在那个搜索栏中，地址已经存在）
这在javascript和jquery中是否可行？请帮我。我是PL的新手。谢谢

AFIK，Google地图搜索API中使用的搜索栏是一个简单的文本框（input type="text"），其id为pac-input
$('#pac-input').val($('your address element').val()); //copy the value
$('#pac-input').focus(); //focus might trigger automatically
答案 1 :(得分：0)
阅读geocoder = new google.maps.Geocoder();
试试这个：
var input_address = $('your address element').val();
geocoder.geocode({address: input_address}, reverseGeocodeResult);
function reverseGeocodeResult(results, status) {
currentReverseGeocodeResponse = results;
if (status == 'OK') {
if (results.length == 0) {
document.getElementById('cong_viec_dia_chi').innerHTML = 'None';
} else {
document.getElementById('cong_viec_dia_chi').innerHTML = results[0].formatted_address;
}
} else {
document.getElementById('cong_viec_dia_chi').innerHTML = 'can't get address';
}
}
