I'm making another attempt to get Jorn's validation plug-in working.
I'm getting this error from Firebug after clicking in the first required field then out
(onfocusout):
validator.settings["on" + event.type].call is not a function
(function($) {$.extend($.fn,{validate:fun...cured when checking element "+element.id
Here's the code...where's my error?
(I'd love to show you an online example, but this is part of an Intranet app...)
Any help appreciated!
$(document).ready(function() {
$('#add-rental-property-form').validate({
    
errorPlacement: function(error, element) {
if(element.attr('id') == 'street_number') {
error.appendTo('#street-number-error');
}
else
        
if(element.attr('id') == 'street_name') {
error.appendTo('#street-name-error');
}
            
else
            
if(element.attr('id') == 'city') {
error.appendTo('#city-error');
}
            
},
onsubmit: false,
            
onfocusout: true,
            
rules: { street_number: "required",
street_name: "required",
city: "required"
},
messages:    { street_number: required: "Please enter the property street number.",
street_name: required: "Please enter the street name.",
city: required: "Please enter the Years."
             },
})
});
