上代码
<!DOCTYPE html> <html>
<head>
<script src="jquery-2.1.3.min.js">
</script>
<script>
$(document).ready(function(){
$("input").blur(function(){
$.ajax({
type:'post',
url:"v.php",
data:$("input").val(),
success:function(data,status){
alert("状态：" + status+"/n"+data);
}
});
});
});
</script>
</head>
<body>
<input type="text" name="data">
</body>
</html>
v.php很简单
<?php $p = $_POST['data']; echo "Hello!".$p; ?>
然后出现服务器端出现"undefined index:data"，本人菜鸟，看不出，求指点
