Html 按钮效果很好，但 css 按钮不行

Question

我不是编码专家，我创建了一个弹出脚本以在用户单击第二个弹出窗口上的 css 按钮后与 cpa 重定向一起使用。 但是当用户单击 css 按钮时，什么也没有发生。我添加了一个 html 按钮，它就像一个魅力。我试图找出根本原因，但没有运气。

$(function() {
  openUp('#overlay')
  $("#popup").on('click', function() {
    openUp('#overlay2')
    closeDown('#overlay')
  });

  function openUp(el) {
    $(el).fadeIn(500, function() {
      $(this).next().show();
    });
  }

  function closeDown(el) {
    $(el).fadeOut(500, function() {
      $(this).next().hide();
    });
  }
  $('a').each(function(index, element) {
    $(this).click(function(e) {
      e.preventDefault();
    });
  });
});

Answer 1

不确定“css-button”是什么，但为什么不像这样将 .button 类添加到按钮：

<button class="button" type="button" id="myBtn" onclick="og_load();">Apply</button>
