首先是评论表单

文件：template\default\space_blog_view.htm

代码：

涂鸦板

然后点击评论按钮调用 'comment_add')"

文件：source\script_ajax.js

代码：

function ajaxpost(formid, func, timeout) {

showloading();

if(ajaxpostHandle != 0) {

return false;

}

var ajaxframeid = 'ajaxframe';

var ajaxframe = $(ajaxframeid);

if(ajaxframe == null) {

if (is_ie && !is_opera) {

ajaxframe = document.createElement("");

} else {

ajaxframe = document.createElement("iframe");

ajaxframe.name = ajaxframeid;

ajaxframe.id = ajaxframeid;

}

ajaxframe.style.display = 'none';

$('append_parent').appendChild(ajaxframe);

}

$(formid).target = ajaxframeid;

$(formid).action = $(formid).action + '&inajax=1';

ajaxpostHandle = [formid, func, timeout];

if(ajaxframe.attachEvent) {

ajaxframe.detachEvent (' ajaxpost_load);

ajaxframe.attachEvent(' ajaxpost_load);

} else {

document.removeEventListener('load', ajaxpost_load, true);

ajaxframe.addEventListener('load', ajaxpost_load, false);

}

$(formid).submit();

return false;

}

然后通过ajaxpostHandle = [formid, func, timeout];调用

文件：source\script_manage.js

代码：

function comment_add(id, result) {

if(result) {

var obj = $('comment_ul');

var newli = document.createElement("div");

var x = new Ajax();

x.get('do.php?ac=ajax&op=comment', function(s){

newli.innerHTML = s;

});

if($('comment_prepend')){

obj = obj.firstChild;

while (obj && obj.nodeType != 1){

obj = obj.nextSibling;

}

obj.parentNode.insertBefore(newli, obj);

} else {

obj.appendChild(newli);

}

if($('comment_message')) {

$('comment_message').value= '';

}

if($('comment_replynum')) {

var a = parseInt($('comment_replynum').innerHTML);

var b = a + 1;

$('comment_replynum').innerHTML = b + '';

}

//提示获得积分

showreward();

}

}

然后通过ajax方法

x.get('do.php?ac=ajax&op=comment', function(s){

newli.innerHTML = s;

});

提交到'do.php?ac=ajax&op=comment'此路径下

文件：source\do_ajax.php

代码：

if($op == 'comment') {

$cid = empty($_GET['cid'])?0:intval($_GET['cid']);

if($cid) {

$cidsql = "cid='$cid' AND";

$ajax_edit = 1;

} else {

$cidsql = '';

$ajax_edit = 0;

}

//评论

$list = array();

$query = $_SGLOBAL['db']->query("SELECT * FROM ".tname($ttb)." WHERE $cidsql authorid='$_SGLOBAL[supe_uid]' ORDER BY dateline DESC LIMIT 0,1");

while ($value = $_SGLOBAL['db']->fetch_array($query)) {

realname_set($value['authorid'], $value['author']);

$list[] = $value;

}

realname_get();

}

返回提交的评论
