Ильфат,
убрать onClick из атрибута кнопки и изменить JS код на

<script type="text/javascript">   
   $(document).ready(function()
   {
      $("#indexForm1").submit(function(event)
      {
         var isValid = $.validate.form(this);
         if (isValid){
			ShowObjectWithEffect('indexButton1', 0, 'explode', 500);
			return true;
		 }
		 else
		 {
			return false;
		 }
      });
      $("#zakaz-brelokCombobox1").validate(
      {
         required: true,
         type: 'select',
         disallowfirstchoice: true,
         color_text: '#000000',
         color_hint: '#00FF00',
         color_error: '#FF0000',
         color_border: '#808080',
         nohint: false,
         font_family: 'Arial',
         font_size: '13px',
         position: 'topleft',
         offsetx: 0,
         offsety: 0,
         effect: 'none',
         error_text: 'Выберите брелок'
      });
      var indexCarousel1Opts =
      {
         delay: 900000,
         duration: 500,
         easing: 'linear',
         mode: 'clip',
         direction: 'vertical',
         pagination: true,
         pagination_img_default: 'images1/page_default.png',
         pagination_img_active: 'images1/page_active.png',
         start: 0
      };
      $("#indexCarousel1").carouseleffects(indexCarousel1Opts);
   });
</script>
