仿的是花瓣登录效果,他默认HTML是这样的

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

点击登录,会在#page里面加上登录框,

<code class="lang-html"><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>登录花瓣</h2>
        </div>
        <div class="body">
            <div class="login-connect">
                <h5>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>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>
</code>

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

<code class="lang-javascript"> onclick="app.showSheet('login', {modal: true});return false;"
</code>

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(){

        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。

<code class="lang-javascript">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());
</code>

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