Posted 2021-05-03

const el = document.getElementById('element');

triggerEvent(el, 'click');

function triggerEvent(element, event) {
  if (document.createEvent) {
    // IE以外
    const e = document.createEvent('HTMLEvents');
    e.initEvent(event, true, true);
    return element.dispatchEvent(e);
  } else {
    // IE
    const e = document.createEventObject();
    return element.fireEvent('on' + event, e)
  }
}
