Validation method

[gchokeen]

Form validation is taking important role in all the applications. So I think cloneya should give the control to user for validating form.

Case:

• Email field is empty or invalid, still we can add new field
• Users what to get confirm user before deleting the form field, like "Are you sure, you want to delete!"

I don't see anyway to achieve this on before_clone or before_delete event callback.

Can return false do the trick ?

I did some work around to achieve above request, please check and tell me this can be implemented.

$(function () {

    var clone = $("#clone");
    clone.click(function () {

        alert("clicked");

        var e = $.Event("before_clone.cloneya");
        $(this).triggerHandler(e);

        if (e.isDefaultPrevented()) {
            return; 
        }

        alert("cloned");
    });

    clone.on("before_clone.cloneya", function (e) {

        if(!confirm('Are you sure, you want to clone this?')){
            e.preventDefault();
        }
    });

});

I created the js fiddle demo here

This is fine, but you'd also need to write the unit tests for validation. Let me know if you need help with that.

I'm keeping it for a future 1.1.0 release. I need to write more tests for nested cloning and deleting. This would've saved me #41

@gchokeen I wanted to discuss the flow. For example, when cloning the following events can be prevented

1. before_clone.cloneya
2. after_clone.cloneya
3. before_append.cloneya
4. after_append.cloneya

So, if 1 is prevented, 2, 3 & 4 would also need to be prevented. Same way, if 2 is prevented, 3 and 4 would also need prevention. I want to avoid too many nested if statements.

@actual-saurabh, I created validation branch to implement this feature. I will implement and update soon.

I think once before_clone.cloneya event prevented all other follow up event's should not trigger. Since we return if event prevented.
