ajaxjquerymysqlphp

先放我做好的效果图。如下图1为编辑前的效果，图2为点击“修改库存”后的效果。html和CSS已经弄出来了，但不懂javascript。修改后的数据直接通过后台php修改到mysql，若成功则直接返回数据到库存的td单元格。

然后是我的html代码。

<tr id="3308">
    <td><img  src="/static/imghwm/default1.png"  data-src="/1369118039-3308.jpg!w120"  class="lazy" / alt="mysql - 怎么用jQuery、Ajax、php实现这样的无刷新编辑功能？" ></td>
    <td><strong>3308</strong></td>
    <td><span>3.97</span> M³</td>
    <td><span>2950.00</span> 元</td>
    <td>2013-05-21 14:36:20</td>
    <td><input type="text" placeholder="输入库存数"></input></td>
    <td><a class="button small success">保存修改</a></td>
</tr>

求兄弟们能给个详细点的答案，实在是不懂javascript啊，整个页面就差这一个功能实现了。另外，这样的表格有长长一列，我可以用php循环生成动态html标签id的。

感谢感谢！

上面回答的，我没有采纳答案，实在是我水平有限，没有修改好。在php100也同提了这个问题，很快得到解决。下面贴上php100的答案，并附上链接，方便他人。

    'num' => 0

if(isset($_POST['id']) && isset($_POST['num'])){
    if(is_numeric($_POST['id']) && is_numeric($_POST['num'])){
        $id = (int)$_POST['id'];
        $num = (int)$_POST['num'];
        $r['msg'] = '修改成功！';
        $r['num'] = $num;
        $r['status'] = TRUE;
    }else{
        $r['msg'] = '错误！[2]';
    }
}else{
    $r['msg'] = '错误！[1]';
}

echo json_encode($r);
?>

<code>$(document).ready(function() {
//为每一个具有相同id=cartUpdate 的 添加click事件
$("#cartUpdate").live("click",function(){
    var text=$(this).text();
    if(text=="修改数量"){
        var count = $(this).parent().prev().text();
        $(this).parent().prev().html("<input style="width:35px" min="1" type="number" value="+count +">");
