我想在我的 Java EE 应用程序中包含 Google Visualization API 的图表。但是,无论我做什么,应用程序都无法识别 API。我以前用过这样的,所以我不明白我做错了什么。有人可以看看我的代码并告诉我我做错了什么吗?谢谢!

// Load the Visualization API and the piechart package.

// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,

function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
错误如下:
- ReferenceError:谷歌未定义
- 方法“setOnLoadCallback”带有下划线并表示:未解析的函数或方法“setOnLadCallback”
