这个是在评论Ajax-1中的willin-kan版基础上改良的，也带再编辑模式。不过采用的是admin-ajax.php来处理ajax请求，将评论处理写入了functions.php文件
首先是js
这段代码没有用on()方法来动态绑定 submit事件，所以在页面ajax重载时不会出现重复提交的现象，而且修改容器名已经被我集中到开头几个变量统一完成。看注释
$(document).ready(function() {
ajaxComt();
});
function ajaxComt(){
var commentform = '#comment_form', // ××× form表单id
comment = 'c_tarea', // ××× textarea 的id 不带#
commentlist = 'comment-list', // ××× 评论列表ul或ol的class，不带点
respond = '#respond', // ××× 评论插入位置，插入在这个id之前
homeUrl = document.location.href.match(/http:\/\/([^\/]+)\//i)[0], // 主页地址，用于下面的提交函数
txt1 = '<div id="loading" class="text-info"> 正在提交, 请稍候...</div>',
txt2 = '<div id="error">#</div>',

加入functions.php的处理代码
可以单独写成一个php文件，然后在functions.php引用
<?php

}
最后注意
提示函数变成了ajax_comment_err($a)，所以某些包含wp_die()的评论提示函数也要改一下，比如禁止英文、日文评论等函数的提示
这个版本不需要在意文件的相对路径。
