使用Ajax在DIV中重新加载MySQL数据

@mgraph已关闭，但如果要在按钮上执行此操作，请单击

在 post.php中 ：

//$UserOption will be Yes/No for button clicks or empty string for first load of the page$UserOption = $_REQUEST['UserClicked'];//Id will be set if a vote has been clicked or empty string if it's the first load$Id = $_REQUEST['Id'];//(Do something with $UserOption)$sql = mysql_query("SELECt * FROM posts WHERe active ='0' LIMIT 1") or die (mysql_error());$row = mysql_fetch_array($sql);echo $row['sitepost'];

JS ：

<script type="text/javascript">$(document).ready(function(){   update(null,null);})function update(Id, Vote) {    $(".post-body").eq(0).load("post.php?UserClicked=" + Vote + "&Id=" + Id);}</script>

HTML ：

<div ></div><button type="button" onclick="update(1, 'Yes');">Yes</button><button type="button" onclick="update(1, 'No');">No</button><button type="button" onclick="update(2, 'Yes');">Yes</button><button type="button" onclick="update(2, 'No');">No</button>

备用HTML / JS

<script type="text/javascript">$(document).ready(function(){    $("#yes").click(function(){        update('Yes');    })    $("#no").click(function(){        update('No');    })    update();})function update(Vote) {    $(".post-body").eq(0).load("post.php?UserClicked=" + Vote);}</script><div ></div><button id="yes" type="button">Yes</button><button id="no" type="button">No</button>
