Date validation in ExtJS

I have a datefield in a form like this:

{
                xtype:'datefield',
                name:'order[date]',
                id:'dato',
                format:'d-m-Y',
                allowBlank: false,
                cls:'inpu开发者_JS百科t_single',
                emptyText:'dd-mm-yyyy',
                minValue:new Date().add('d',-1),
                onFocus: function(){
                    if (this.el.getValue() == 'dd-mm-yyyy') {
                        Ext.getCmp('dato').setValue('');    
                    }

                },
                msgTarget:'side',
                minText:'Must be future date',
                validationEvent:false


            }

Now my problem is that i want to force user to use dd-mm-yyyy format, but with the above code the user can type 01102010 for 1st of october 2010.

I thought that format:'d-m-y' would force this, but it dont.

Validation should be clientside.

So either the field should reformat the date to 01-10-2010 onblur or it should just not allow other formats than dd-mm-yyyy. Last version is prefered :)

Thanks in advance!

Just did a bit more researching in the api documentaion and found

altFormats:'d-m-Y',

That solved the problem. Now it will only accept the above format.

You can create and use your own VType and including it you can check whether a user has entred a valid date or not. Besides it offers you more reusability furhter. For refernce:http:docs/#!/api/Ext.form.field.VTypes
