Hi folks.
I'm using WebBrowser automation to fill informations in a website.
Sometimes I need to delete some informations and, when I click on a link, a messagebox is displayed requesting to confirm the operation.
I've tried to change the script in the onclick attribute using setAttribute without success.
Here is the code in onclick attribute:

<A id=declaracaoForm:j_id110:0:j_id112 title="Excluir Valor." onclick="javascript: if (!confirm('Confirma a exclusao?')){ return false;} else {showDIV('aguarde');};A4J.AJAX.Submit('_viewRoot','declaracaoForm',event,{'parameters':{'declaracaoForm:j_id110:0:j_id112':'declaracaoForm:j_id110:0:j_id112'} ,'actionUrl':'/dsnSPWEB/xhtml/declaracao/inserirDeclaracao.jsf','oncomplete':function(request,event,data){hideDIV('aguarde');showErrMsg();},'similarityGroupingId':'declaracaoForm:j_id110:0:j_id112'} );return false;" href="https://cert01.fazenda.sp.gov.br/dsnSPWEB/xhtml/menu/menu.jsf#" name=declaracaoForm:j_id110:0:j_id112>AC - R$0,01</A>

Please, someone could help me to solve this?
