我的 PHP 代码 (budgetingMain.php) 中有一个名为“totals”的数组。我想将它用于我的数据以创建 Google 饼图。但是,我很难对其进行编码。
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
var jsontotals = <?php echo json_encode($totals) ?>;
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Category');
data.addColumn('number', 'Amount Spent on it');
data.addRows([
'jsontotals'
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chartcontainer'));
chart.draw(data, options);
}
</script>
在当前的设置中,我收到以下错误:“Uncaught SyntaxError: Unexpected token <” for this line。
var jsontotals = <?php echo json_encode($totals) ?>;
我意识到这是嵌入的问题,但我找不到让它工作的方法。欢迎任何帮助!
编辑:这是总数的结构
$totals = array(
array("ClothingAndAccessories",0),
array("FlowersAndDecorations",0),
array("Ceremony",0),
array("Reception",0),
array("Photography",0),
array("Gifts/favours",0),
array("Stationary",0),
array("Entertainment",0),
array("Other",0)
);
