Question

我有一个不同切片的AmPiechart。我想对每个切片的单击进行不同的操作。

PieChart.addListener("clickSlice", handleClickPie);

function handleClickPie(e) {

        }

我想做类似的事情：

如果ClickSliceNo == 1：Action1

如果ClickSliceNo == 2：Action2

如果ClickSliceNo == 3：Action3

我如何在handleClickPie（）函数中处理它？</ p>

是的，正如您在评论中指出的那样，您可以访问切片项的属性，然后根据需要处理这些属性。

以下是一个例子：

var chart = AmCharts.makeChart("chartdiv", {

function myCustomClick(e) {
    // to see the full api, log out "e"
    // console.log(e);
    var country = e.dataItem.dataContext.country;
    if (country === "Lithunia") {
        alert("Lithuania: the home of amCharts.");
    } else if (country === "Germany") {
        alert("Munich is a city in Germany.");
    } else if (country === "Austria") {
        alert("Skiing in Austria is awesome.");
    } else {
        alert("You have clicked " + country + ".");
    }
