javascript - 如何在单击按钮时转换动画？

标签 javascript jquery html css

我对文本有一个动画效果:“Bluebox”。它不断地过渡到不同的颜色。我希望在单击提交按钮后将此文本转换为蓝色。 (注意；提交按钮会将您带到下一页)但是，一旦我在下面添加此 JS 和 css，蓝框颜色动画就会完全中断。

$('.submitbutton').click(function(e) {
  $submit = $(this);
  e.preventDefault();
  $('form').animate({
    opacity: "0"
  }, {
    duration: "slow",
    $("text color-text-flow").addclass('BBblue'),
    complete: function() {
      $submit.parents('form').submit();
    }
  });
});
@keyframes Blueboxblue {
  from {
    color: '';
  }
  to {
    color: blue
  }
}

.BBblue {
  animation: Blueboxblue ease 2s;
}

以下是“我的”代码，如果您需要，可以在没有上述 js/css 的情况下工作!:)

$('.text').html(function(i, html) {
  var chars = $.trim(html).split("");
  return '<span>' + chars.join('</span><span>') + '</span>';
});

最佳答案

按钮不必是类型提交，任何按钮都可以触发表单提交。 此外，addclass 应该是 addClass

$('.submitbutton').click(function(e) {
    e.preventDefault();
    $(".textdisplay").addClass('BBblue');
    setTimeout(function(){ $('#form1').submit(); }, 2000);
});
@keyframes Blueboxblue {
  from {
    color: '';
  }
  to {
    color: blue
  }
}

.BBblue {
  animation: Blueboxblue ease 2s infinite;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<span class="textdisplay">this is a test</span>

<form id="form1">
<button class="submitbutton">Submit</button>
</form>
