javascript - 有什么方法可以在 window.onload 中设置 google onload 回调吗？

Question

这是我的代码:

window.onload = function(){
  google.load("visualization", "1", {packages:["corechart"]});
  google.setOnLoadCallback(function(){
    alert("Message");
  });
}

有什么办法让这段代码工作吗？

Answer 1

Google 文档中的函数:

function loadMaps() {
  google.load("maps", "2", {"callback" : mapsLoaded});
}

它似乎有回调对象，你可以在这里分配任何你喜欢的函数。

谷歌说:

You can load the Google API loader dynamically by creating a script element and setting its source to the same "https://www.google.com/jsapi?INSERT-YOUR-KEY" URL with an additional query callback parameter. The callback will be executed when the loader is ready.
