第一步屏蔽默认评论js

将header.php中的<?php $this->header(); ?>改为<?php $this->header('commentReply='); ?>

第二步放置重构的js代码

将下面的一堆js代码放到comments.php下面（代码压缩过我自己也看不明白了哈哈哈）

<script type="text/javascript">
function showhidediv(id){var sbtitle=document.getElementById(id);if(sbtitle){if(sbtitle.style.display=='flex'){sbtitle.style.display='none';}else{sbtitle.style.display='flex';}}}
(function(){window.TypechoComment={dom:function(id){return document.getElementById(id)},pom:function(id){return document.getElementsByClassName(id)[0]},iom:function(id,dis){var alist=document.getElementsByClassName(id);if(alist){for(var idx=0;idx<alist.length;idx++){var mya=alist[idx];mya.style.display=dis}}},create:function(tag,attr){var el=document.createElement(tag);for(var key in attr){el.setAttribute(key,attr[key])}return el},reply:function(cid,coid){var comment=this.dom(cid),parent=comment.parentNode,response=this.dom("<?php echo $this->respondId(); ?>"),input=this.dom("comment-parent"),form="form"==response.tagName?response:response.getElementsByTagName("form")[0],textarea=response.getElementsByTagName("textarea")[0];if(null==input){input=this.create("input",{"type":"hidden","name":"parent","id":"comment-parent"});form.appendChild(input)}input.setAttribute("value",coid);if(null==this.dom("comment-form-place-holder")){var holder=this.create("div",{"id":"comment-form-place-holder"});response.parentNode.insertBefore(holder,response)}comment.appendChild(response);this.iom("comment-reply","");this.pom("cp-"+cid).style.display="none";this.iom("cancel-comment-reply","none");this.pom("cl-"+cid).style.display="";if(null!=textarea&&"text"==textarea.name){textarea.focus()}return false},cancelReply:function(){var response=this.dom("<?php echo $this->respondId(); ?>"),holder=this.dom("comment-form-place-holder"),input=this.dom("comment-parent");if(null!=input){input.parentNode.removeChild(input)}if(null==holder){return true}this.iom("comment-reply","");this.iom("cancel-comment-reply","none");holder.parentNode.insertBefore(response,holder);return false}}})();
</script>

第三步

删除comments.php中的取消回复的按钮

<div class="cancel-comment-reply">
<?php $comments->cancelReply(); ?>
</div>

第四步 将回复按钮替换为回复与取消按钮

如果你的模板重构过评论列表，那么将回复按钮处的代码换成为下面代码即可

<span class="comment-reply cp-<?php $comments->theId(); ?> text-muted comment-reply-link"><?php $comments->reply('回复'); ?></span><span id="cancel-comment-reply" class="cancel-comment-reply cl-<?php $comments->theId(); ?> text-muted comment-reply-link" style="display:none" ><?php $comments->cancelReply('取消'); ?></span>

如果你的模板没有重构过评论列表，比如默认模板，建议学习下typecho的自定义评论列表的文档

第五步 重构样式

将下面的css加入到模板css中即可

#cancel-comment-reply-link {
    display: inline !important;
}
