javascript - 带调用功能的jQuery触发器

我有onclick按钮：

 <button   class="tablinks" onclick="openDiv(event, 'default')">{'TEXT_DEFAULT_SETTINGS'|tr}</button>

openDiv函数：

function openDiv(evt, cityName) {
  // Declare all variables
  var i, tabcontent, tablinks;
  // Get all elements with class="tabcontent" and hide them
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  // Get all elements with class="tablinks" and remove the class "active"
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }

  // Show the current tab, and add an "active" class to the button that opened the tab
  document.getElementById(cityName).style.display = "block";
  evt.currentTarget.className += " active";
}

如何触发此onclick？

最佳答案

尝试：

document.getElementsByClassName("tablinks")[0].click()
