Form submition with jQuery is not working correctly with IE8

Answer 1

I replaced my jquery code with this and it is working on all browsers:

jQuery(document).ready(function(){

    jQuery('.ajaxform').submit( function() {

        $.ajax({
            url     : $(this).attr('action'),
            type    : $(this).attr('method'),
            dataType: 'json',
            data    : $(this).serialize(),
            success : function( data ) {
                        for(var id in data) {
                            jQuery('#' + id).html( data[id] );
                        }
                      }
        });

        return false;
    });

});

I don't know what is this but it is working now. Thanks to all to participate and help me to solve this issues.
