我正在尝试在 Android 应用程序中加载 Google 图表。但是，它抛出 google 未定义的错误。下面是我的 HTML 文件和 JavaScript 文件。
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Patient Vitals</title>
<link href="../../common/scripts/lib/css/jquery.mobile.theme-1.1.0.css" rel="stylesheet" type="text/css" />
<link href="../../common/scripts/lib/css/jquery.mobile-1.0.1.min.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="../../common/scripts/lib/css/jquery.mobile.datebox.css" />
<link href="../scripts/css.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
<script src="../../common/scripts/jsapi.js" type="text/javascript">
google.load('visualization', '1.0', {'packages':['corechart']});
</script>
<script src="../scripts/patient_vitals.js"></script>
</head>
<body>
<div class="PT_Care_vitals_swa_ofcurv_left" onclick="getPatientVitalInfo();"</div>
</body>
</html>
patient_vitals.js:
getPatientVitalInfo =function()
{
logInformation("Get Patient Vital Information ");
alert("Get Patient Vital info");
//code to retieve data from database
drawChart(temp);
}
drawChart = function(temp)
{
alert("Inside drawChart function");
//Convert array int DataTable
var data = google.visualization.arrayToDataTable(temp);
rowCount = data.getNumberOfRows();
// Instantiate and draw our chart, passing in some options.
chart = new google.visualization.LineChart(document.getElementById('chart_div'));
var options = {'tooltip': {'trigger':'none'}, 'year': "numeric", 'month': "numeric",'day': "numeric", 'pointSize':5};
//Function to perform select operation
//Drawing the chart in HTML page
chart.draw(data, options);
}
这里，google.visualization.arrayToDataTable(temp) 抛出这个错误。对此有什么想法吗？如何解决？我还尝试将 google.Visulization 保留在 .js 文件中。但它也不起作用。如果我从浏览器运行相同的代码，它工作正常。是安卓的问题吗？
最佳答案
好像有点奇怪。尝试改变
<script src="../../common/scripts/jsapi.js" type="text/javascript">
google.load('visualization', '1.0', {'packages':['corechart']});
</script>
到
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">google.load('visualization', '1.0', {'packages':['corechart']});</script>
然后应该正确加载 google 对象。此外，您还粘贴了来自谷歌图表示例的图表初始化，
chart = new google.visualization.LineChart(document.getElementById('chart_div'));
但你唯一的 HTML 是
<div class="PT_Care_vitals_swa_ofcurv_left" onclick="getPatientVitalInfo();"</div>
你错过了 chart_div id
