如何在Typescript中实现JS函数指针

我在Javascript中有以下内容:

var chartOptions = {
    chartType: settings.chartType,
}

chartOptions.func = function(chart) {
    chartOptions.fullChart = chart;
}

一切正常.

但是我想把它改成TypeScript并且是新的,我不确定如何做到这一点.请有人帮忙吗？例如,'func'没有符号,'fullChart'没有符号,那么这怎么会在Javascript中起作用？

您可以修改代码,将属性添加到chartOptions:

var chartOptions = {
    chartType: settings.chartType,
    func: null,
    fullChart: null
}

chartOptions.func = function(chart) {
    chartOptions.fullChart = chart;
}

如何将代码转换为类？它更像TypeScript-y :)

class ChartOptions {
    public chartType;
    public fullChart;

    public func(chart: any) {
        this.fullChart = chart 
    }
}    

let chart = {};
let chartOptions = new ChartOptions();
chartOptions.func(chart);
