"data-remote" attribute query parameter support

[vuraldincer]

Some frameworks (ex: stripes FW) for receiving data-remote address parameters are a problem. It's supposed to parse the given parameters.

   if (!errors.length && $el.val() && $el.data('remote')) {
      this.defer($el, function () {
      var remoteUri = (function(uri) {
            if( -1 === uri.indexOf('?') ) return uri;
            return uri.substr( 0,uri.indexOf('?') );
      })( $el.data('remote') );         
      var qs = (function(uri) {
            var b = {};
            if( -1 === uri.indexOf('?') ) uri+='?';
            var a = uri.substr( uri.indexOf('?')+1 ).split('&');  
            if( "" === a || "" === a[0] ) return b;
            for (var i = 0; i < a.length; ++i)
            {
                var p=a[i].split('=', 2);
                if ( p.length === 1 && ""!==p[0] )
                    b[ p[0] ] = "";
                else
                    if( ""!==p[0] ) b[ p[0] ] = decodeURIComponent( p[1].replace(/\+/g, " "));
            }
            return b;                       
        })( $el.data('remote') );        
        var data = {};
        data[ $el.attr('name') ] = $el.val();
        $.extend( data, qs );                
        $.get( remoteUri, data)
          .fail(function (jqXHR, textStatus, error) { errors.push( getErrorMessage('remote') || error ) })
          .always(function () { deferred.resolve(errors)})
      })
    } else deferred.resolve(errors)
