Jquery Impromptu Callback issue - $.prompt fails

问题


I have an issue with jQuery Impromptu, specifically $.prompt with a callback function for an inline form.

Now, the actual specific problem is the following. If the email_address field is blank when submitted I cannot get the $.prompt('Please supply an email address for the customer') to work, however if I change it to alert('Please supply an email address for the customer') it will work.

I am guessing this is a scope issue as the other $.prompt calls work as expected which I assume are because they are inside a $.post callback function.

I have struggled to find a huge amount of documentation of the callback form functionality and although I feel like I understand the e, v and f variables, the m (Message) is not something I've used before. When I log m to the console log it looks like the jQuery Impromptu object, however I am unsure how to access a property of it. I have tried m.prompt() and $.m.prompt() but these are just guesses on how I would access the prompt function.

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 }});

With the new event system the callback is bound onto the prompt. So callback must be called before the prompt is destroyed. Impromptu is not intended for multiple prompts at one time.

If you should want to work around this an easy solution would be to setTimeout(10, function(){ $.prompt(...); }); Inside of the callback. This will give opportunity for the previous prompt to close.

Fixed 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');  
                    $('#email_address').val($('#old_email_address').val());  
                }  
            }, 'json');  
        }  
    }  
    else  
    {  
        $('#email_address').val($('#old_email_address').val());  
    }  
}  

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