添加到日历按钮/链接

Question

我正在尝试创建“添加到日历”链接/按钮。当我单击按钮/链接时，它将为我提供Google日历/ outlook日历/ yahoo日历等选项。这是我要在文件中添加的一个片段。

我从https://www.addevent.com/那里得到了

有人对此有想法吗？谢谢！

function myFunction() {
    document.getElementById("myDropdown").classList.toggle("show");
}

// Close the dropdown if the user clicks outside of it
window.onclick = function(event) {
  if (!event.target.matches('.dropbtn')) {

    var dropdowns = document.getElementsByClassName("dropdown-content");
    var i;
    for (i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      if (openDropdown.classList.contains('show')) {
        openDropdown.classList.remove('show');
      }
    }
  }
}

.dropbtn {
    background-color: white;
    border: 1px solid #777;
    color: #4c4c4c;
    padding: 16px;
    font-size: 16px;
    cursor: pointer;
}

.dropdown {
    position: relative;
    display: inline-block;
}
.dropdown-content {
    display: none;
    position: absolute;
    background-color: #fff;
    border: 1px solid lightgray;
    min-width: 200px;
    overflow: auto;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 1;
}

.dropdown-content a {

    padding: 12px 16px;
    text-decoration: none;
    display: block;
