var xmlHttp;
function getValue(){
alert("getvaluel");
var question =document.insertForm.question.value;
// alert(question);
var answer = document.insertForm.answer.value;
// alert(answer);
submit(question,answer);
};
function submit(question,answer){
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{
alert ("Your browser does not support AJAX!");
return;
}
xmlHttp.onreadystatechange =function(){
if(xmlHttp.readyState ==4){
alert(xmlHttp.responseText);
}
};
var url = "insert1.php";
xmlHttp.open("post",url,true);
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded; charset=utf-8");
xmlHttp.send("question="+question+"&answer="+answer);
}
function GetXmlHttpObject()
{
var xmlHttp=null;
try
{
// Firefox, Opera 8.0+, Safari
xmlHttp=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}

复制代码 代码如下:

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
//echo $_POST["question"];
//echo $_POST["answer"];
$q =$_POST['question'];
$a = $_POST['answer'];
//$q='qq';
//$a="a";
$con = mysql_connect("localhost","joe","123");
if (!$con)
{
//die('Could not connect: ' . mysql_error());
echo 'Could not connect: ' . mysql_error();
}
mysql_select_db("joe",$con);
mysql_query("INSERT INTO message VALUES ('$q', '$a', '无')");
mysql_close($con);
echo "输入成功";
?>
