Html按钮效果很好，但css按钮没有

Question

我不是编码的专家，我在用户点击第二个弹出窗口上的css按钮后创建了一个弹出脚本，用于cpa重定向。 但是当用户点击css按钮时，没有任何反应。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，但为什么不将.button类添加到按钮中，如下所示：

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