我需要取消设置$ _POST ['u'],但只在javascript函数中,现在$ _POST ARRAY在页面准备好后自动取消设置...
function resetChat(cod_c){
if(confirm('are you sure?')){
if (sendReq.readyState == 4 || sendReq.readyState == 0) {
sendReq.open("POST", 'getChat.php?chat='+cod_c+'&last=' + lastMessage, true);
sendReq.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
sendReq.onreadystatechange = handleResetChat;
var param = 'action=reset';
param += '&user=' + document.getElementById('cod_user').value;
sendReq.send(param);
document.getElementById('txt_message').value = '';
}
<?php unset($_POST['u']); ?> // this only 1 time after confirm???
}
}
function handleResetChat() {
}

PHP是服务器端语言,JavaScript在客户端:)您需要了解有关webdev的更多信息;)
