我正在尝试使用coffeescript来模拟这个asynchronously-loaded map。
这是我的咖啡因:
initialize = ->
mapOptions =
zoom: 8
center: new google.maps.LatLng(-34.397, 150.644)
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions)
return
loadScript = ->
script = document.createElement("script")
script.type = "text/javascript"
script.src = "https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&" + "callback=initialize"
document.body.appendChild script
return
$(window).load ->
loadScript()
编译为:
(function() {
var initialize, loadScript;
initialize = function() {
var map, mapOptions;
mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
};
loadScript = function() {
var script;
script = document.createElement("script");
script.type = "text/javascript";
script.src = "https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&" + "callback=initialize";
document.body.appendChild(script);
};
$(window).load(function() {
return loadScript();
});
}).call(this);
然后我收到错误:
Uncaught TypeError: Object [object global] has no method 'initialize'
据我所知,我可能需要使initialize()
方法可以访问文档的范围,但由于coffeescript将所有模块包装在匿名函数中,因此使这项工作的最佳方法是什么?
答案 0 :(得分:6)
window.initialize = ->
# ...
P.S。考虑给它一个更独特的名字。
