PHP之即点即改

html:

<td data-hide="1200" class="px12" id ="<?php echo $v['g_id'];?>" ><span class="click"><?php echo $v['g_price'];?></span></td>

<script language="javascript" type="text/javascript">
$(function () {
    $(".click").click(function ()
     {
        var _this = $(this);
        var old_val  = _this.html();
        _this.parent().html("<input type='text' name=" + old_val + " class='focus' value=" + old_val + " />");
        $(".focus").focus();
        $('.focus').blur(function(){
            var _this = $(this);
            var new_val = _this.val();
            var id = _this.parents().attr("id");
            $.post("http://www.she.com/admin.php?rand=46&moduleid=32&file=gift&action=gift_jidianjigai",{g_price: new_val, g_id:id}, function(msg) {
                 if(msg=='2'){
                     _this.parent().html('<span class="click">' + new_val + '</span>');
                 }else{
                     _this.parent().html('<span class="click">' + old_val + '</span>');
                 }
            })
        })
    })
})
</script>

php 后台处理

        if(!empty($g_id)&&!empty($g_price))
        {
            $res= $db->query("UPDATE `{$DT_PRE}gift` SET `g_price`='$g_price' WHERE `g_id`=$g_id");
            if($res){
                echo 2;
            }else{
                echo 1;
            }
        }else{
            echo 1;
        }
