ajaxphp

仿的是花瓣登录效果，他默认HTML是这样的

<a onclick="app.showSheet('login', {modal: true});return false;" href="#" class="login btn wbtn"><span class="text"> 登录</span></a>

点击登录，会在#page里面加上登录框，

<div class="sheet-overlay" style="opacity: 1;"></div>
<div id="sheet" class="destroy" style="display: block; top: 72px;">
    <div id="sheet_login" class="sheet">
        <div class="head">
            <h2 id="登录花瓣">登录花瓣</h2>
        </div>
        <div class="body">
            <div class="login-connect">
                <h5 id="使用合作网站帐号登录">使用合作网站帐号登录</h5>
                <div class="connections clearfix"><a href="/oauth/weibo/instant_login/" onClick="return false;" class="weibo login-button">新浪微博</a><a href="/oauth/douban/instant_login/" onClick="return false;" class="douban login-button">豆瓣</a><a href="/oauth/renren/instant_login/" onClick="return false;" class="renren login-button">人人网</a><a href="/oauth/qzone/instant_login/" onClick="return false;" class="qzone login-button">QQ</a></div>
                <p class="less">未注册过花瓣也可以直接登录哦</p>
            </div>
            <div class="login-form">
                <h5 id="使用注册邮箱登录">使用注册邮箱登录</h5>
                <form id="auth_form" action="https://huaban.com/auth/" method="post" class="Form FancyForm AuthForm">
                    <ul>
                        <li>
                            <div class="input email">
                                <input id="login_email" name="email" type="text" value="">
                                <label>花瓣注册邮箱</label>
                                <span class="fff"></span></div>
                        </li>
                        <li>
                            <div class="input password">
                                <input id="login_password" name="password" type="password">
                                <label>密码</label>
                                <span class="fff"></span></div>
                        </li>
                    </ul>
                    <div class="non_inputs"><a id="login_btn" href="#" onClick="return false;" class="btn btn18 rbtn"><strong> 登录</strong><span></span></a><a id="reset_password" href="#" onClick="return false;" class="less fr">忘记了密码？</a><a id="back_to_login" href="#" style="display: none;" onClick="return false;" class="less fr">哦，又想起来了!</a></div>
                </form>
                <div id="reset_msg" style="display: none;" class="success"></div>
            </div>
            <div class="clear"></div>
        </div>
        <a href="#" title="关闭" onClick="app.hideSheet();return false;" class="close"></a></div>
</div>

点击关闭后，会删除这个登录框。而且出来的时候是向下拉，关闭的时候是向上收，我把上面代码放在/include/pop-login.php里面

 onclick="app.showSheet('login', {modal: true});return false;"

他这样的方式怎么写

<code>$('.login').on('click',function(){
    $.ajax({
        async: false,
        url: "/include/pop-login.php",
        cache: false,
        success: function(html){
            $("#page").append(html);
        }
    });
});
$('#sheet_login .close').live('click',function(){
    $('.sheet-overlay').remove();
    $('#sheet').remove();
});
</code>

<code>$('.login').on('click',function(){
    $.ajax({
        async: false,
        url: "/include/pop-login.php",
        cache: false,
        success: function(html){
            $("#page").append(html);
        }
    });
});
$('#sheet_login .close').live('click',function(){
    $('.sheet-overlay').remove();
    $('#sheet').remove();
});
</code>

大概这种感觉？

<code>function on_click_login(){
    $.ajax({
        async: false,
        url: "/include/pop-login.php",
        cache: false,
        success: function(html){
            $("#page").append(html);
        },
        error: function(){
            $('.login').one('click',on_click_login);
        }
    });
}

$('.login').one('click',on_click_login);
$('#page').on('click','#sheet_login .close',function(){
    $('.sheet-overlay').remove();
    $('#sheet').remove();
    $('.login').one('click',on_click_login);
});
</code>

PS，因为不喜欢live所以随手改掉了……

也碰到过楼主的这样的问题，那个时候也没有什么好方法解决。当时用了一个很丑陋的方法解决掉的。
当时在页面上写了一个隐藏变量，每次ajax触发之前，都清零，ajax执行成功之后，延迟100ms，才给他赋值，然后每次按键的时候，都预先判断这个隐藏变量是否有值。

var popLogin = {
    isLock: false,
    init: function() {
        if (popLogin.isLock) {
            //TODO...
            return false;
        }
        $.ajax({
            url: "/include/pop-login.php",
            cache: false,
            success: function(html){
                $("#page").append(html);
            },
            complete: function() {
                popLogin.isLock = false;
            }
        });
    }
};

$('.login').on('click', popLogin.init());

难道不是在click时disable掉按钮，然后在ajax结束的时候enable吗……

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AM

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AM

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
