我使用的是Google饼图,我想在饼图上禁用点击事件。这是我的代码:
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['State Group', 'Names'],
['Andhra Pradesh', 9],
['Madhya Pradesh', 4.5],
['Tamilnadu / Pondicherry', 7],
['Karnataka', 2.5],
['Others', 1]
]);
var options = {
// title: 'My Daily Activities',
pieSliceText: 'none',
pieHole: 0.80,
slices: { 0: {color: '#46B1C9'},
1: {color: '#84C0C6'},
2: {color: '#F37992'},
3: {color: '#6A6478'},
4: {color: '#C9CCCA'},
},
};
var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
chart.draw(data, options);
}
我已经使用此代码禁用了点击事件,但是不知何故!
google.visualization.events.addListener(chart, 'ready', function(){
$("#donutchart").unbind("click");
});
google.visualization.events.addListener(chart, 'ready', function(){
$("#donutchart").unbind("click").click(onClick);
尝试一下...
我几年前就知道这一点,但我一直在努力弄清楚这一点,并提出了一种解决方案。
我的问题是我正在使用HTML功能自定义工具提示,但是当我单击图形的一部分时,工具提示的css将被清除干净。
我能够使用Google图表为您提供的方法来隔离选择事件(getSelection(),请参阅文档here,这实际上令人困惑,因为他们将其直接放置在全局窗口中。
[一旦我发现我实际上将事件传递给了自定义处理程序,并做了一些陪审团的决定,以不禁用单击/选择事件(因为这似乎不太可能),而是保留我的自定义CSS(在我的用例之外,可以以多种方式使用此逻辑)
[您可以在下面看到我的代码,其中我使用返回的事件行,并将其与一些硬编码数据(名称,颜色)进行匹配,以更改这些工具提示CSS。然后,一旦我能够捕获并记录选择信息,就将其传递给处理程序以执行相同的操作。我还必须使用对象作为状态形式,因为由于某些原因,当您两次单击图表切片时,Google图表会返回一个空数组,而不是带有事件对象的数组。
希望这对以后的所有人有帮助!
