我正在尝试使用 google chart 创建一个表，但它返回了表方法构造的错误。我看到了几个引用资料，但我认为错误是在 jsapi 库中给出的，所以谷歌没有定义。

这是我的 html 代码，如您所见，它非常简单，我只是想绘制表格，但总是返回这些错误
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.1/jquery.min.js"></script>
<script src="https://www.gstatic.com/charts/loader.js"></script>
<meta name="layout" content="bootstrap">
</head>
<body>
<div class="cabecalho"></div>
<div id="table_div"></div>
<script type="text/javascript">
google.charts.load('current', {
packages: ['bar', 'corechart', 'table'],
callback: drawCharts
});
function drawCharts() {
drawChartUsersActive();
}
function drawChartUsersActive() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Name');
data.addColumn('number', 'Salary');
data.addColumn('boolean', 'Full Time Employee');
data.addRows([
['Mike', {v: 10000, f: '$10,000'}, true],
['Jim', {v:8000, f: '$8,000'}, false],
['Alice', {v: 12500, f: '$12,500'}, true],
['Bob', {v: 7000, f: '$7,000'}, true]
]);
var table = new google.visualization.Table(document.getElementById('table_div'));
table.draw(data, {showRowNumber: true, width: '100%', height: '100%'});
}
</script>
</body>
</html>
最佳答案
您是否尝试替换:
google.charts.load('current', {
packages: ['bar', 'corechart', 'table'],
callback: drawCharts
});
function drawCharts() {
drawChartUsersActive();
}
通过:
google.charts.load('current', {'packages':['table']});
google.charts.setOnLoadCallback(drawChartUsersActive());
这正是文档中所写的内容，所以也许它有效；)
关于javascript - 类型错误 google.visualization.DataTable 不是构造函数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57496387/
