地圖未載入HTML頁面

Question

我有一個要加載到HTML頁面的地圖，該地圖的文件位於app文件夾中，但不加載。 這是插入地圖的地方的代碼

    <!-- Contact section edn -->

這是js文件，其中包含加載地圖所需的所有代碼。

    //Initialize google map for contact setion with your location.

function initializeMap() {

var lat = '44.8164056'; //Set your latitude.
var lon = '20.46090424'; //Set your longitude.

var centerLon = lon - 0.0105;

var myOptions = {
    scrollwheel: false,
    draggable: false,
    disableDefaultUI: true,
    center: new google.maps.LatLng(lat, centerLon),
    zoom: 15,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};

//Bind map to elemet with id map-canvas
var map = new google.maps.Map(document.getElementById('map-canvas'), myOptions);
var marker = new google.maps.Marker({
    map: map,
    position: new google.maps.LatLng(lat, lon),
});

var infowindow = new google.maps.InfoWindow();

google.maps.event.addListener(marker, 'click', function () {
    infowindow.open(map, marker);
});

infowindow.open(map, marker);
google.maps.event.addDomListener(window, 'load', initializeMap);

}

我看到其他人也遇到類似的問題，但他們通過在標記區域中鍵入optimized：false來解決了這個問題，但對我來說仍然無法正常工作。

Answer 1

您有兩個問題：

1. 您調用google.maps.event.addDomListener(window, 'load', initializeMap); 在 initializeMap()本身內部 -那么自然就不會初始化地圖。

2. 您需要在#map-canvas上設置一些尺寸； 即使不是問題＃1，也永遠不會顯示地圖。

糾正了這兩個問題后，它就可以工作-> http://jsfiddle.net/1fdzz7gv/

小提琴的代碼與OP中的代碼完全相同，只是google.maps.event.addDomListener(window, 'load', initializeMap); 放置在initializeMap()外部，並已為#map-canvas提供了一些尺寸

#map-canvas {
    width: 300px;
    height: 200px;
}
