      var dealType = document.dealForm.dealType;
    if(dealType){
      dealType.value ="repost";
    }
    document.dealForm.singleOperOfferId.value=offerId;
    document.dealForm.submit();
}
...............................

<form name="dealForm" id="dealForm" method="post" action="" style="display:inline">
        <div class="wns_list_ops">
        <input type="hidden" name="action" value="deal_my_offer"/>
