我已经在网站上添加了地图，但似乎无法添加带有地图的搜索框来搜索位置。我已经给出了下面的代码，我用来添加地图。有人能帮忙在代码中添加搜索框吗？
<div id="googleMap" style="width:100%;height:400px;"></div>
function myMap() {
var mapProp= {
center:new google.maps.LatLng(12.9716, 77.5946),
zoom:10,
};
var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
google.maps.event.addListener(map, 'click', function(e) {
placeMarker(e.latLng, map);
document.getElementById("latitude").value = e.latLng.lat();
document.getElementById("longitude").value = e.latLng.lng();
});
function placeMarker(position, map) {
var marker = new google.maps.Marker({
position: position,
map: map
});
map.panTo(position);
}
}
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=MYAPIKEY&callback=myMap"></script>
您可以在代码中使用自动完成。它将提供一个建议列表来完成用户的输入。一旦你从列表中选择了这个地方，你就可以获得这个地方的属性，将其显示在地图上，并在上面打上标记
这是一个简化的代码，我将您的代码合并到谷歌地图平台自动完成代码示例中。

您也可以在此处查看此简化代码。
您可以使用这样的东西：
// Create the search box and link it to the UI element.
var input = /** @type {HTMLInputElement} */(
document.getElementById('pac-input'));
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
var searchBox = new google.maps.places.SearchBox(
/** @type {HTMLInputElement} */(input));
