// 获取元素并触发点击
document.getElementById('myButton').click();

// 或者使用querySelector
document.querySelector('.my-class').click();

// 创建并触发自定义事件
var event = new MouseEvent('click', {
  view: window,
  bubbles: true,
  cancelable: true
});
var element = document.getElementById('myButton');
element.dispatchEvent(event);

// 简单点击
$('#myButton').click();

// 触发点击事件
$('#myButton').trigger('click');

// 带参数的触发
$('#myButton').trigger({
  type: 'click',
  extraData: 'some value'
});

// 确保DOM加载完成
document.addEventListener('DOMContentLoaded', function() {
  document.getElementById('myButton').click();
});

// 或者使用jQuery的ready
$(document).ready(function() {
  $('#myButton').click();
});

// 阻止事件冒泡
$('#myButton').click(function(e) {
  e.stopPropagation();
  // 你的代码
});

// 使用事件委托
$(document).on('click', '.dynamic-element', function() {
  // 处理点击
});

// 或者使用MutationObserver监听DOM变化
var observer = new MutationObserver(function(mutations) {
  if (document.getElementById('dynamicButton')) {
    document.getElementById('dynamicButton').click();
    observer.disconnect();
  }
});
observer.observe(document.body, {childList: true, subtree: true});

setTimeout(function() {
  $('#myButton').click();
}, 3000); // 3秒后点击

if (someCondition) {
  document.querySelector('.target').click();
}

function simulateClick(element) {

  var clientY = rect.top + rect.height/2;
