jQuery getScript和Google Maps API错误消息 [英] jQuery getScript and Google Maps API Error message

问题描述

我用自己的对象初始化了地图，google maps api通过加载jquery.getscript。但我总是会在回调函数中收到错误消息：

  var MyGMap = {
 GMapScriptURL：http：/ /maps.google.com/maps?file=api&v=2&async=2&a​​mp;key=，
 Map：null，
 Geocoder：null，
 InitiazlizeMaps：function（） {
 if（GBrowserIsCompatible（））{
 this.Map = new GMap2（document.getElementById（map_canvas））; 
 this.Map.setCenter（new GLatLng（37.4419，-122.1419），13）; 
 this.Geocoder = new GClientGeocoder（）; 
 
 
 
 $ b $（function（）{
 var CurrentKey =MY_KEY; 
 
 $。 getScript（MyGMap.GMapScriptURL + CurrentKey，function（）{
 MyGMap.InitiazlizeMaps（）; 
 // throws GMap2 is undefined 
 
}）; 
}）; 
  

最新错误？为什么没有运行？

解决方案

您有 async = 2 在脚本URL行中，这意味着异步加载映射核心 - 您需要等待它完成之后才能调用InitializeMaps。您可以尝试从URL中删除 async = 2 ，或者使用Google Map的异步和回调代替getScript回调函数，例如

  $。getScript（MyGMap.GMapScriptURL + CurrentKey +& callback = MyGMap.InitializeMaps）; 
  

I got a problem with loading the google maps api.

I got my own object with a function that initializes the map, and the google maps api gets loaded via jquery.getscript. but i always get an error message in the callback function:

var MyGMap = {
    GMapScriptURL: "http://maps.google.com/maps?file=api&v=2&async=2&key=",
    Map: null,
    Geocoder: null,
    InitiazlizeMaps: function () {
        if (GBrowserIsCompatible()) {
            this.Map = new GMap2(document.getElementById("map_canvas"));
            this.Map.setCenter(new GLatLng(37.4419, -122.1419), 13);
            this.Geocoder = new GClientGeocoder();
        }
    }
}

$(function(){
    var CurrentKey = "MY_KEY";

    $.getScript(MyGMap.GMapScriptURL + CurrentKey, function () {
        MyGMap.InitiazlizeMaps();
        // throws GMap2 is undefined

    });
});

whats wrong? why is this not running?

解决方案

You've got async=2 in the script URL line which means load the mapping core asynchronously too - you need to wait for it to complete that before you can call InitializeMaps. You can either try dropping the async=2 from the URL, or using Google Map's async and callback instead of the getScript callback function, e.g.

$.getScript(MyGMap.GMapScriptURL + CurrentKey + "&callback=MyGMap.InitializeMaps");
