【解决方案1】：

这个怎么样

document.getElementById("targetElm").dispatchEvent(new Event('click'));

这是一个工作示例...

document.getElementById("targetElm").dispatchEvent(new Event('click'));

<svg version="1.1" class="highcharts-root" style="font-family:MontserratRegular;font-size:12px;" xmlns="http://www.w3.org/2000/svg" width="441" height="319.5" viewBox="0 0 441 319.5">
    <rect id="targetElm" onclick="alert('hi')"/>
</svg>

即创建一个点击事件并将其分派给元素。尽管您的问题中似乎没有任何单击事件的处理程序。

【讨论】：

事件处理程序存在，它工作正常，由 highcharts plotOptions: {bar: { dataLabels: { enabled: false } }, series: { events: { click: function (event) { //一些代码} } }, },
对不起，罗伯特先生，它正在工作，但在我的情况下不起作用这不是你的问题，我只是尝试在 highcharts 栏上模拟鼠标点击事件，实际上这是我的问题
这就是为什么当你问下一个问题时，你应该确保它包含minimal reproducible example
@MahmoudHassan 你可以查看文档api.highcharts.com/highcharts/plotOptions.bar.events.click
为我工作。作为 jquery 选择的元素，只需使用 $(selector)[0].dispatchEvent(new Event('click'))

【解决方案2】：

您可以为此使用名为 firePointEvent 的 Highcharts 内部函数：

var chart = Highcharts.chart('container', {

  series: [{
    type: 'column',
    data: [1],
    point: {
        events: {
        click: function() {
            console.log('Click event fired');
        }
      }
    }
  }]
});

chart.series[0].points[0].firePointEvent('click');
