jquery.validate plugin - how to trim values before form validation

Question

I\'m using the excellent jquery.validation plugin by Jörn Zaefferer and I was wondering whether there\'s a easy way to automatically trim form elements before they are valid

Answer 1

In jquery validation you will find the below code:

required: function( value, element, param ) {

        // Check if dependency is met
        if ( !this.depend( param, element ) ) {
            return "dependency-mismatch";
        }
        if ( element.nodeName.toLowerCase() === "select" ) {

            // Could be an array for select-multiple or a string, both are fine this way
            var val = $( element ).val();
            return val && val.length > 0;
        }
        if ( this.checkable( element ) ) {
            return this.getLength( value, element ) > 0;
        }
        return value.length > 0;
    }

Change the value.length to $.trim(value).length
