javascript - 如何使用Javascript在iframe中加载Google Map？

我在iframe中加载Google Map时遇到麻烦。我想做something like this，但是在iframe中。我以不同的方式尝试过:

尝试在加载脚本之前调用showNewMap()函数。但是我收到以下错误:未捕获的TypeError:对象[object global]没有方法'showNewMap':http://jsfiddle.net/9RE4h/1/

var iframe = document.createElement("iframe");
document.body.appendChild(iframe);
var doc = iframe.contentWindow || iframe.contentDocument;
if (doc.document) { doc = doc.document;}

function showNewMap() {

    var mapContainer =  doc.createElement('div');
    mapContainer.setAttribute('style',"width: 500px; height: 300px");
    doc.body.appendChild(mapContainer);

    var mapOptions = {
        center: new google.maps.LatLng(-35.000009, -58.197645),
        zoom: 5,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    }

    var map = new google.maps.Map(mapContainer,mapOptions);
}

var script = doc.createElement('script');
script.type = 'text/javascript';
script.src = 'https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=true&' + 'callback=showNewMap';
doc.getElementsByTagName('head')[0].appendChild(script);

有解决问题的主意吗？

最佳答案

兼容Firefox-Google Chrome:

var iframe = document.createElement("iframe");
iframe.onload = function() {
   var doc = iframe.contentDocument;

   iframe.contentWindow.showNewMap = function() {
    var mapContainer =  doc.createElement('div');
    mapContainer.setAttribute('style',"width: 500px; height: 300px");
    doc.body.appendChild(mapContainer);

    var mapOptions = {
        center: new this.google.maps.LatLng(-35.000009, -58.197645),
        zoom: 5,
        mapTypeId: this.google.maps.MapTypeId.ROADMAP
    }

    var map = new this.google.maps.Map(mapContainer,mapOptions);
}

var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=true&' + 'callback=showNewMap';
iframe.contentDocument.getElementsByTagName('head')[0].appendChild(script);
};
document.body.appendChild(iframe);
