jQuery的即兴回拨问题 - $ .prompt失败(Jquery Impromptu Call

我有一个问题jQuery的即兴，特别是.prompt $用了一种直列形式的回调函数。

现在，实际的具体问题如下。如果email_address交房时我不能让该字段为空$.prompt('Please supply an email address for the customer')的工作，但是如果我改变它alert('Please supply an email address for the customer')它将工作。

我猜这是一个范围问题，因为其他$.prompt调用如预期的工作，我认为是因为他们是内部$.post回调函数。

我一直在努力发现一个巨大的回调形态功能的文档量，虽然我觉得我了解e ， v和f变量中， m （消息）是不是我以前用过的。当我登录m到控制台登录，它看起来像jQuery的即兴对象，但我不能确定如何访问它的属性。我曾尝试m.prompt()和$.m.prompt()但这些都只是猜测对我将如何访问prompt功能。

使用Javascript

var txt = '<input type="text" name="email_address" value="" />';

function mycallbackform(e,v,m,f)
{  
    if(v != undefined)  
    {  
        if (v == true)  
        {  
            console.log(f);  
            if (f.email_address.length == 0)  
            {  
                console.log(m);  
                $.prompt('Please supply an email address for the customer');  
            }  
            else  
            {  
                $.post('". $this->view->url(array(), 'admin-create-user-from-checkout') ."', f, function(data) {  
                if(data.status)  
                {  
                    $.prompt('Customer Record Created Successfully');  
                }  
                else  
                {  
                    $.prompt('Customer Record could not be created');  
                    $('#email_address').val($('#old_email_address').val());  
                }  
            }, 'json');  
        }  
    }  
    else  
    {  
        $('#email_address').val($('#old_email_address').val());  
    }  
}  

$.prompt(txt,{callback: mycallbackform, buttons: { Ok: true, Cancel: false }});

随着新的事件系统回调势必到提示。因此，被破坏的提示回调之前，必须调用。即兴不能用于多个提示一次。

如果您想解决这个一个简单的解决办法是的setTimeout（10，函数（）{$ .prompt（...）;}）; 里面的回调。这将给予一个提示关闭的机会。

固定的Javascript

var txt = '<input type="text" name="email_address" value="" />';

function mycallbackform(e,v,m,f)
{  
    if(v != undefined)  
    {  
        if (v == true)  
        {  
            if (f.email_address.length == 0)  
            {  
                setTimeout(function(){ $.prompt('Please supply an email address for the customer');  }, 10);
            }  
            else  
            {
                $.post('". $this->view->url(array(), 'admin-create-user-from-checkout') ."', f, function(data) {  
                if(data.status)  
                {  
                    $.prompt('Customer Record Created Successfully');  
                }  
                else  
                {  
                    $.prompt('Customer Record could not be created');
