Hi,

how to validate an input text before submitting or placing the cursor in another field?

I've tried this below but it doesn't work.

$(document).ready(function () {

    $

("input").keyup(function() {

        $

("#jander").validate({

                rules

: {
                    
'coche4[marca]': "required"
                
},

                messages

: {  
                    
'coche4[marca]': 'This field is required'
                
}
        
});

    

});


});

Regards

Javier
