• php ajax


    1.下面是一个简单的php ajax 程序,你可以复制下来进行操作学习。
    php代码:
    <?php
    $host ='127.0.0.1:3306';
    $root ='root';
    $password ='123456';
    $dbname= 'Test';
    $connect = mysql_connect($host,$root,$password,$dbname);

    mysql_select_db("Test", $connect);//erp_database是库名

    if (!$connect)
    {

    die('Could not connect: ' . mysql_error());

    }
    $name = $_POST['name'];
    $password = $_POST['password'];
    $login = mysql_query("select * from login where name ='".$name."' and password = '".$password."' ");
    //$login = mysql_query("select * from login ");

    $arr_login = mysql_fetch_array($login);

    echo json_encode($arr_login);
    ?>

    $(function() {
    $("#subbtn").click(function() {
    var params = $("input").serialize(); //得到输入框中的参数
    var url = "login.php"; //需要跳转的路径。
    $.ajax({
    type: "post", //
    url: url,
    dataType: "json",
    data: params, //以键/值对的形式 或着现在这个样子
    success: function(msg){ //返回成功的的函数

    var backdata = "您提交的姓名为:" + msg.name +
    "<br /> 您提交的密码为:" + msg.password;
    $("#backdata").html(backdata);
    $("#backdata").css({color: "green"});
