webView.getSettings().setJavaScriptEnabled(true);
webView 加载此 html 代码:
<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([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]);
var options = {title: 'Company Performance'};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id='chart_div' style='width: 900px; height: 500px;'></div>
</body>
</html>
这是来自 Google 的示例可视化的代码:折线图
webView 显示文本cannot set property 'overflow' of null
