我的代码如下:
drawGraph() {
let theChart;
let handler = () => {
let sel = theChart.getChart().getSelection();
alert('selection occurred');
console.log('selection event', sel, Object.keys(sel));
};
this.google = this.getGoogle();
this.dataTable = this.getDataTable();
this.orgData.fillDataTable(this.dataTable, 'PALA,SRINIVASRAO');
console.log('data', this.dataTable);
this.dataTable.setRowProperty(1, 'style', 'border: 0');
this.chart = this.createWrapped('OrgChart', 'chartDiv', this.dataTable);
theChart = this.chart;
this.chart.draw();
this.google.visualization.events.addListener(this.chart, 'select', handler);
}
图表绘制正常,我的外翻处理程序被点击但getSelection()只返回[“0”]。顺便说一下,createWrapped正在使用google.visualization.ChartWrapper。
那么我做错了什么?除了试图让我在TypeScript下工作,我的意思是。 :)
答案 0 :(得分:0)
getSelection()
是图表方法,而不是 ChartWrapper 方法
而不是......
this.chart.getChart().getSelection()
