幸运弗兰克的答案很好,但它只是打印一个警报框.这是一个更完整的答案.我把链接放在DataTable中,然后我创建了一个DataView,因此它们不会传递给图表.
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'link', 'Hours per Day'],
['Work', 'http://www.thefreedictionary.com/work', 11],
['Eat', 'http://www.thefreedictionary.com/eat', 2],
['Commute', 'http://www.thefreedictionary.com/commute', 2],
['Watch TV', 'http://www.thefreedictionary.com/television',2],
['Sleep', 'http://www.thefreedictionary.com/sleep', 7]
]);
var view = new google.visualization.DataView(data);
view.setColumns([0, 2]);
var options = {
title: 'My Daily Activities'
};
var chart = new google.visualization.PieChart(
document.getElementById('chart_div'));
chart.draw(view, options);
var selectHandler = function(e) {
window.location = data.getValue(chart.getSelection()[0]['row'], 1 );
}
// Add our selection handler.
google.visualization.events.addListener(chart, 'select', selectHandler);
}
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 900px;"></div>
</body>
</html>
顺便说一下,Google Charts API真的很棒!谢谢谁写了这个.
