dwz关闭当前dialog

　　首先，前台代码如下：

<form method="post" class="pageForm required-validate" onsubmit="return validateCallback(this, dialogAjaxDone)">

　　其次后台Java代码中设置回调参数

Struts2Utils.getResponse().getWriter().write("{\"statusCode\":\"200\",\"message\":\"成功\",\"navTabId\":\"\",\"rel\":\"\",\"callbackType\":\"closeCurrent\",\"forwardUrl\":\"\",\"confirmMsg\":\"\"}");
