ecshop网站头部如何实现ajax登录登出

ecshop可以在网站头部或者是在首页实现无刷新的ajax登录登出效果，代码如下

只需找到themes/我的模板名称/library/member_info.lbi，，将里面的代码用下面的代码替换即可，样式您可以根据自己的网站风格进行调整

<!–{if $user_info}–>

<div class="lef_tit_bj">会员登陆</div><div class="left_conn_bj"> <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td height="50" align="center" valign="middle"><label><strong>Hello {$user_info.username}</strong></label></td> </tr> <tr> <td height="30" align="center" valign="middle"><strong>欢迎光临本店</strong></td> </tr> <tr> <td height="40" align="center" valign="bottom"><label> <a href="user.php?act=logout"> <img src="../images/tuichu.gif"></a> &nbsp; <a href="user.php"> <img src="../images/jinrultan.gif"></a> </label></td> </tr> </table></div></div>

<!–{else}–>

<div class="lef_tit_bj">会员登录</div><div class="left_conn_bj"> <form id="ECS_LOGINFORM" name="ECS_LOGINFORM" method="post" action="javascript:signIn()"> <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td height="50" align="right" valign="middle">用户名：</td> <td height="50" align="left" valign="middle"><label> <input type="text" name="username" class="yonhu_input" style="height:15px;"/> </label></td> </tr> <tr> <td height="30" align="right" valign="middle"> 密&nbsp; 码：</td> <td height="30" align="left" valign="middle"><input type="password" name="password" class="yonhu_input" style="height:15px;" /></td> </tr> <tr> <td height="40" colspan="2" align="center" valign="bottom"><label> <input type="image" name="imageField" src="images/denglu_bann.jpg" /> &nbsp; <a href="user.php?act=register"><img src="images/zhuce_bann.jpg" border="0" /></a> </label></td> </tr> </table> </form></div></div><!–{/if}–> {literal} <script type="text/javascript">function signIn(){ var frm = document.forms[‘ECS_LOGINFORM’];

if (frm) { var username = frm.elements[‘username’].value; var password = frm.elements[‘password’].value; var captcha = ”; if (frm.elements[‘captcha’]) { captcha = frm.elements[‘captcha’].value; }

if (username.length == 0 || password.length == 0) {{/literal} alert("{$lang.empty_username_password}");{literal} return; } else { Ajax.call(‘user.php?act=signin’, ‘username=’ + username + ‘&password=’ + encodeURIComponent(password) + ‘&captcha=’ + captcha, signinResponse, "POST", "TEXT"); } } else { alert(‘Template error!’); }}

属于自己的不要放弃，已经失去的留作回忆。
