我有一个PHP页面,里面有一个表格。
该表填充了来自 MySQL 数据库的记录。表(外壳)的一个字段可以包含两个值:0
和 1
。
当学生housed
字段的值为 1 时,否则为 0。在表中,我想使用带有O/I的JQUERY UI按钮(如开关)。
单击按钮时,需要在MySQL表中更新该值,并且应该在JQUERY UI按钮的右侧显示一个图标("checked")
如果值为1,则图标应该消失。
我想我需要 ajax 来做到这一点?
谁能告诉我这是否可以做到?也许如何做到这一点?
是的,可以做到
这里有一个例子 http://openenergymonitor.org/emon/node/107
哪个说
- 在服务器上创建一个名为 api.php 的 php 脚本
- 复制并粘贴以下示例并保存:
<?php
//--------------------------------------------------------------------------
// Example php script for fetching data from mysql database
//--------------------------------------------------------------------------
$host = "localhost";
$user = "root";
$pass = "root";
$databaseName = "ajax01";
$tableName = "variables";
//--------------------------------------------------------------------------
// 1) Connect to mysql database
//--------------------------------------------------------------------------
include 'DB.php';
$con = mysql_connect($host,$user,$pass);
$dbs = mysql_select_db($databaseName, $con);
//--------------------------------------------------------------------------
// 2) Query database for data
//--------------------------------------------------------------------------
$result = mysql_query("SELECT * FROM $tableName"); //query
$array = mysql_fetch_row($result); //fetch result
//--------------------------------------------------------------------------
// 3) echo result as json
//--------------------------------------------------------------------------
echo json_encode($array);
?>
然后
在同一
- 目录中创建一个名为 client.php 的 html 脚本,其中包含以下内容:
<!---------------------------------------------------------------------------
Example client script for JQUERY:AJAX -> PHP:MYSQL example
---------------------------------------------------------------------------->
<html>
<head>
<script language="javascript" type="text/javascript" src="jquery.js"></script>
</head>
<body>
<!-------------------------------------------------------------------------
1) Create some html content that can be accessed by jquery
-------------------------------------------------------------------------->
<h2> Client example </h2>
<h3>Output: </h3>
<div id="output">this element will be accessed by jquery and this text replaced</div>
<script id="source" language="javascript" type="text/javascript">
$(function ()
{
//-----------------------------------------------------------------------
// 2) Send a http request with AJAX http://api.jquery.com/jQuery.ajax/
//-----------------------------------------------------------------------
$.ajax({
url: 'api.php', //the script to call to get data
data: "", //you can insert url argumnets here to pass to api.php
//for example "id=5&parent=6"
dataType: 'json', //data format
success: function(data) //on recieve of reply
{
var id = data[0]; //get id
var vname = data[1]; //get name
//--------------------------------------------------------------------
// 3) Update html content
//--------------------------------------------------------------------
$('#output').html("<b>id: </b>"+id+"<b> name: </b>"+vname); //Set output element html
//recommend reading up on jquery selectors they are awesome
// http://api.jquery.com/category/selectors/
}
});
});
</script>
</body>
</html>
