javascript - Google Places Autocomplete - 点击模糊的第一个结果

Question

我正在使用 Google Places Autocomplete，我只是希望它在表单字段中触发模糊事件并且存在建议时触发结果列表中顶部项目的点击事件。

var pac_input = document.getElementById('pick-auto');

                (function pacSelectFirst(input) {
                  // store the original event binding function
                  var _addEventListener = (input.addEventListener) ? input.addEventListener : input.attachEvent;

                  function addEventListenerWrapper(type, listener) {
                    // Simulate a 'down arrow' keypress on hitting 'return' when no pac suggestion is selected,
                    // and then trigger the original listener.
                    if (type == "keydown" || type == "blur") {
                      var orig_listener = listener;
                      listener = function(event) {
                        var suggestion_selected = $(".pac-item-selected").length > 0;
                        var keyCode = event.keyCode || event.which;
                        if ((keyCode === 13 || keyCode === 9) && !suggestion_selected) {
                          var simulated_downarrow = $.Event("keydown", {
                            keyCode: 40,
                            which: 40
                          });
                          orig_listener.apply(input, [simulated_downarrow]);
                        } else if(event.type === 'blur') {
                            pac_input.value =
                             $(".pac-container .pac-item:first-child").text();
                            // $(".pac-container").delegate(".pac-item:first-child","click",function(){
                            //  console.log("success");
                            // });

                            $(".pac-container .pac-item:first-child").bind('click',function(){
                                console.log("click");
                            });

                        }
                        orig_listener.apply(input, [event]);
                      };
                    }

                    // add the modified listener
                    _addEventListener.apply(input, [type, listener]);
                  }

                  if (input.addEventListener)
                    input.addEventListener = addEventListenerWrapper;
                  else if (input.attachEvent)
                    input.attachEvent = addEventListenerWrapper;

                })(pac_input);


                $(function() {
                  var autocomplete = new google.maps.places.Autocomplete(pac_input);
                });

试试这个:

演示:http://jsfiddle.net/q7L8bawe/

添加此事件:

$("#pick-auto").blur(function (e) {
        if (e.which == 13) {
            var firstResult = $(".pac-container .pac-item:first").text();

            var geocoder = new google.maps.Geocoder();
            geocoder.geocode({"address":firstResult }, function(results, status) {
                if (status == google.maps.GeocoderStatus.OK) {
                    var lat = results[0].geometry.location.lat(),
                        lng = results[0].geometry.location.lng(),
                        placeName = results[0].address_components[0].long_name,
                        latlng = new google.maps.LatLng(lat, lng);

                        $(".pac-container .pac-item:first").addClass("pac-selected");
                        $(".pac-container").css("display","none");
                        $("#pick-auto").val(firstResult);
                        $(".pac-container").css("visibility","hidden");

                }
            });
        } else {
            $(".pac-container").css("visibility","visible");
        }

    });
