 密码:

 ajax提交

 


 

ajax.php

<?php 
echo '用户名:',$_POST['name'],',密码：',$_POST['pwd']."
";
//这里可以进行一些操作，比如数据库交互


echo "操作完毕";
?>

For example, modify the code in JQueryAjax to the following form:

 用户名:

 密码:

 ajax提交

 

ajax.php

<?php 
$name = $_POST['name'];
$pwd = $_POST['pwd'];
$array = array("$name","$pwd");
//这里进行一个些操作，比如数据库交互

echo json_encode($array);//json_encode方式是必须的
?>

The operation effect is as follows:
