pessoal alterei a função function adicionar(chave,qtd){ var tmp = document.getElementById('rem'); tmp.innerHTML = 'Carregando ...'; ajaxRequest.open("GET", "teste_adiciona.php?chave="+chave+"&qtd="+qtd, true); ajaxRequest.send(null); ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 1){ tmp.innerHTML = 'Carregando readstate...'; } if(ajaxRequest.readyState == 2){ tmp.innerHTML = 'Carregando 2 ...'; } if(ajaxRequest.readyState == 4){ tmp.innerHTML = ''; tmp.innerHTML = ajaxRequest.responseText; } }}No firefox funciona, mais no IE nao funciona , ele nem chega entrar nessa função "ajaxRequest.onreadystatechange = function(){"
