私はGoogle Maps APIを使用しています。ページを読み込む際に問題なく動作していますが、ボタンがonclickの場合、Googleマップを表示したいと考えています。私の作業コード：Google Maps APIがonclickイベントで機能しない
function initMap() {
var directionsDisplay = new google.maps.DirectionsRenderer;
var directionsService = new google.maps.DirectionsService;
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 14,
center: {
lat: 12.9577129,
lng: 77.6764937
} // Starting Point Marathahalli
});
directionsDisplay.setMap(map);
calculateAndDisplayRoute(directionsService, directionsDisplay);
}
function calculateAndDisplayRoute(directionsService, directionsDisplay) {
var selectedMode = document.getElementById('mode').value;
/* configure waypoints */
var waypts = [];
waypts.push({
location: {
lat: 12.9583665,
lng: 77.6635659
}, // HAL
stopover: true
}, {
location: {
lat: 12.9630167,
lng: 77.6268656
},
stopover: true
});
directionsService.route({
origin: {
lat: 12.9577129,
lng: 77.6764937
}, // Haight.
destination: {
lat: 12.9868068,
lng: 77.6070679
}, // Ending Point Shivaji Nagar.
travelMode: google.maps.TravelMode[selectedMode],
waypoints: waypts
}, function(response, status) {
if (status == 'OK') {
directionsDisplay.setDirections(response);
console.log(response);
} else {
window.alert('Directions request failed due to ' + status);
}
});
}/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html,
body {
height: 100%;
margin: 0;
padding: 0;
}
#floating-panel {
position: absolute;
top: 10px;
left: 25%;
z-index: 5;
background-color: #fff;
padding: 5px;
border: 1px solid #999;
text-align: center;

$('#btn-submit').click(function(e){

$.ajax({

data : $('#testForm').serialize(),
success: function(data) {
var res = jQuery.parseJSON(data);
console.log(res);
},
error:function(exception){
alert('Exeption:'+exception);
}
});
});
：
{

"count": 2,
"data": [

]
}
私の期待する答え：
私は"status": "success",を取得しているときにAJAXの応答応答で、その時だけ私はマップを表示したい、これを行うには？
