Question

我一直致力于这个非常简单的Google商家信息搜索，除了ZERO_RESULTS之外我什么都得不到。此时我没有意义，因为我的地图正在工作，并在单独的AJAX函数中显示我的数据库中的标记。我已经记录了我的对象和变量，似乎一切都很好。

为什么成功回调适用于我的使用ZERO_RESULTS的其他声明？

$( "#submit3" ).click(function(e) {
    e.preventDefault();
    findPlaces();
    $('#results').text("Triggah3!");
});

function findPlaces() {

    var lat = document.getElementById("latitude").value;
    var lng = document.getElementById("longitude").value;
    var cur_location = new google.maps.LatLng(lat, lng);

    // prepare request to Places
    var request = {
        location: cur_location,
        radius: 50000,
        types: 'bank'
    };

    // send request
    service = new google.maps.places.PlacesService(map);
    service.search(request, createMarkers);
}

// create markers (from 'findPlaces' function)
function createMarkers(results, status) {
    if (status == google.maps.places.PlacesServiceStatus.OK) { //ZERO_RESULTS

        // if we have found something - clear map (overlays)
        clearOverlays();

        // and create new markers by search result
        for (var i = 0; i < results.length; i++) {
            createMarker(results[i]);
        }
    } else if (status == google.maps.places.PlacesServiceStatus.ZERO_RESULTS) {
        alert('Sorry, nothing is found');
    }
}

// create single marker function
function createMarker(obj) {

    // prepare new Marker object
    var mark = new google.maps.Marker({
        position: obj.geometry.location,
        map: map,
        title: obj.name
    });
    markers.push(mark);

    // prepare info window
    var infowindow = new google.maps.InfoWindow({
        content: '<img src="' + obj.icon + '" /><font style="color:#000;">' + obj.name + 
        '<br />Rating: ' + obj.rating + '<br />Vicinity: ' + obj.vicinity + '</font>'
    });

    // add event handler to current marker
    google.maps.event.addListener(mark, 'click', function() {
        clearInfos();
        infowindow.open(map,mark);
    });
    infos.push(infowindow);
}

Answer 1

types应该是一个数组。

使用：

types: ['bank']

Google商家信息和ZERO_RESULTS
