我面临这个错误,不知道为什么会出现这个错误.我正在使用codeigniter,这是
jquery错误.
这是我的浏览页面
<script>
$(function() {
$("#accordion").accordion({
collapsible: true,heightStyle: "content"
});
});
var data = google.visualization.arrayToDataTable([
['Attendance Type','Count'],['Present',<?PHP echo $student_attendance_count['present']; ?>],['Absent',<?PHP echo $student_attendance_count['absent']; ?>],['On Leave',<?PHP echo $student_attendance_count['leave']; ?>],['Attendance Not Maked',<?PHP echo $attendance_not_marked; ?>]
]);
var options = {
title: 'My Daily Activities'
};
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data,options);
</script>
这是我的HTML页面检查这个以供参考.如果您需要更多详细信息,我将在此处添加.我不知道这个错误是怎么来的.

请帮我.
解决方法
确保正确加载Google Visualization API.
文件在这里：
https://google-developers.appspot.com/chart/interactive/docs/basic_load_libs
你可能需要这样的东西：
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
// Load the Visualization API library and the piechart library.
google.load('visualization','1.0',{'packages':['corechart']});
google.setOnLoadCallback(drawChart);
// ... draw the chart...
</script>
