由于您的问题缺少信息，以下是 Google 自动完整文本输入。您输入位置，它将返回显示在li标签中的城市、州、国家、邮政编码、纬度、经度（它找到的）。您可以使用该方法存储在其他变量中，而不是li. 这是它的jsfiddle。

    $(document).ready(function(){
        var geocoder;
        geocoder = new google.maps.Geocoder();
        var defaultBounds = new google.maps.LatLngBounds(
          new google.maps.LatLng(-33.8902, 151.1759),
          new google.maps.LatLng(-33.8474, 151.2631));

        var input = document.getElementById('location');
        var options = {
          bounds: defaultBounds,
          types: ['(regions)']
        };

        autocomplete = new google.maps.places.Autocomplete(input, options);

        google.maps.event.addListener(autocomplete, 'place_changed', function() {
            var place = autocomplete.getPlace(); 
            var city;
            var state;
