我有几个函数可以使用 Google Charts API 实例化各种图表。
当我在没有 jQuery 的情况下调用它们时$(document).ready方法，一切正常。但用这种方法，我看到的是空白屏幕。
Why?
<script type="text/javascript" src = "http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js" charset="utf-8"></script>
<script type="text/javascript" src = "http://www.google.com/jsapi" charset="utf-8"></script>
function drawColumnChart1(){..some code..}
function drawColumnChart2(){..some code..}
function drawGeoChart(){.some code..}
//This works fine.
google.load("visualization", "1", {packages:["piechart", "corechart", "geomap"]});
google.setOnLoadCallback(window.drawColumnChart1);
google.setOnLoadCallback(window.drawColumnChart2);
google.setOnLoadCallback(window.drawGeoChart);
//This doesn't work
$(document).ready(function(){
google.load("visualization", "1", {packages:["piechart", "corechart", "geomap"]});
google.setOnLoadCallback(window.drawColumnChart1);
google.setOnLoadCallback(window.drawColumnChart2);
google.setOnLoadCallback(window.drawGeoChart);
});
UPDATE这是我在 Firebug 中遇到的错误：
uncaught exception: [Exception... "Could not convert JavaScript argument" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame :: http://www.google.com/jsapi :: Q :: line 20" data: no]

Line 22
google.setOnLoadCallback 与 jQuery $(document).ready() 可以混合使用吗？ https://stackoverflow.com/questions/556406/google-setonloadcallback-with-jquery-document-ready-is-it-ok-to-mix
可能是最接近的答案，Ryan Wheale 对以下问题的回答也可能有帮助。
多次使用 google.setOnLoadCallback 可以吗？ https://stackoverflow.com/questions/1380043/is-it-ok-to-use-google-setonloadcallback-multiple-times
