这花了一些时间，但我认为这样的东西会对你起作用。如果你在这方面遇到任何问题，请告诉我。

// Initialize an object
let obj = {};

// Trigger when DOM loads
window.addEventListener('DOMContentLoaded', () => {
  // Get current Date in UNIX
  let currentDate = Date.now();
  // An hour in UNIX
  const hour = 3600000;
  // The date to reclick
  let reclickDate = currentDate + hour;

  // If already clicked
  if (localStorage.getItem('clickData')){
    // Parse the JSON object from localStorage
    let data = JSON.parse(localStorage.getItem('clickData'));
    // The Date to Reclick
    reclickDate = Date(parseInt(data.clickTime)+hour);
  }
  // Otherwise click now and set object JSON
  else {
    document.getElementById("myBtn").click();
    obj.clickTime = Date.now();
    localStorage.setItem('clickData', JSON.stringify(obj));
  }

  // Recursive Function
  checkForClick(currentDate, reclickDate);
});

const checkForClick = (currentDate, reclickDate) => {
  setTimeout(() => {

    // If 1 hour passed
    if (currentDate > reclickDate){
      // Reclick
      document.getElementById("myBtn").click();
      // Set localStorage new data
      obj.clickTime = Date.now();
      localStorage.setItem('clickData', JSON.stringify(obj));
      // Break function
      return;
    }

    // Otherwise recall the function
    checkForClick(currentDate+1000, reclickDate);
  }, 1000);
}

在jQuery中使用文档就绪函数尝试以下代码：

$(document).ready(function(){
    $("#myBtn").trigger('click'); 
});
