地址自动填充功能无法在网站

Question

这是我的javascript代码。我在google API中添加了这个。如果我进入水中......它应该显示＆＃34;海德拉巴，特伦甘纳，印度＆＃34;。但它没有显示出来。如何在现场获得这些自动填充？

        var card = document.getElementById('pac-card');
        var input = document.getElementById('pac-input');
        var types = document.getElementById('type-selector');
        var strictBounds = document.getElementById('strict-bounds-selector');

        map.controls[google.maps.ControlPosition.TOP_RIGHT].push(card);

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


        autocomplete.addListener('place_changed', function() {
          infowindow.close();
          marker.setVisible(false);
          var place = autocomplete.getPlace();

            // User entered the name of a Place that was not suggested and
            // pressed the Enter key, or the Place Details request failed.
            window.alert("No details available for input: '" + place.name + "'");
            return;
