javascript - ionic : click event taking time for selecting places from Google Places api

Question

我是 IONIC 的新手。我正在尝试在我的 ionic 应用程序中使用 google places api。我可以通过 Google Places api 获取这些地方。但问题是我必须长按应用中的自动完成选项，否则选择不会反射(reflect)在应用中。

这是我的 Html 代码。

<script src="http://maps.googleapis.com/maps/api/js?sensor=false&amp;libraries=places"></script>    
<input id="pac-input" class="controls" type="text" placeholder="Search Box" data-tap-disabled="true">
<div id="map" data-tap-disabled="true"></div>

这是我的 MapController.js

     .controller('MapCtrl', function($scope, $rootScope, $state, $cordovaGeolocation, $ionicLoading, Markers, $ionicPopup, $location, SearchAll, shareData, constants) {        
initAutocomplete();

        function initAutocomplete() {
          console.log("in Map Autocomplete");
            var map = new google.maps.Map(document.getElementById('map'), {
                center: { lat: 19.075984, lng: 72.877656 },
                zoom: 13,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            });

            // Create the search box and link it to the UI element.
            var input = document.getElementById('pac-input');
            var searchBox = new google.maps.places.SearchBox(input);
            // map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);

            // Bias the SearchBox results towards current map's viewport.
            map.addListener('bounds_changed', function() {
                searchBox.setBounds(map.getBounds());
            });

            var markers = [];
            // [START region_getplaces]
            // Listen for the event fired when the user selects a prediction and retrieve
            // more details for that place.
            searchBox.addListener('places_changed', function() {
                var places = searchBox.getPlaces();

                console.log("in searchBox Listner");

                if (places.length == 0) {
                    return;
                }

                console.log("Places : ", places);
                console.log("LAT : ", places[0].geometry.location.lat());
                console.log("LAONG : ", places[0].geometry.location.lng());
                // Clear out the old markers.
                markers.forEach(function(marker) {
                    marker.setMap(null);
                });
                markers = [];

                // For each place, get the icon, name and location.
                var bounds = new google.maps.LatLngBounds();
                places.forEach(function(place) {
                    var icon = {
                        url: place.icon,
                        size: new google.maps.Size(71, 71),
                        origin: new google.maps.Point(0, 0),
                        anchor: new google.maps.Point(17, 34),
                        scaledSize: new google.maps.Size(25, 25)
                    };

                    // Create a marker for each place.
                    markers.push(new google.maps.Marker({
                        map: map,
                        icon: icon,
                        title: place.name,
                        position: place.geometry.location
                    }));

                    if (place.geometry.viewport) {
                        // Only geocodes have viewport.
                        bounds.union(place.geometry.viewport);
                    } else {
                        bounds.extend(place.geometry.location);
                    }
                });
                map.fitBounds(bounds);
            });
            // [END region_getplaces]
        }
});

此问题的解决方案在 https://github.com/driftyco/ionic/issues/1798 中讨论。 .问题是 google 会动态添加需要 data-tap-disabled 属性的元素，因此您必须在 google 将这些元素添加到 dom 后手动添加该属性。

$scope.disableTap = function () {
    var container = document.getElementsByClassName('pac-container');
    angular.element(container).attr('data-tap-disabled', 'true');
    var backdrop = document.getElementsByClassName('backdrop');
    angular.element(backdrop).attr('data-tap-disabled', 'true');
    // leave input field if google-address-entry is selected
    angular.element(container).on("click", function () {
        document.getElementById('pac-input').blur();
    });
};

现在将 ng-change='disableTap()' 添加到您的输入:

<input ng-change='disableTap()' id="pac-input" class="controls" type="text" placeholder="Search Box" data-tap-disabled="true">

github 链接使用 ng-focus 但 ng-change 对我来说效果更好，因为有时在触发焦点时生成的元素还不存在。
