ajax同步刷新

jsajax.js

//图片形式状态切换
function toggle(url,action,obj,str,id){//状态转换/obj-当前对象/str-传入类型字符串/id-传入ID
    $.ajax({
        type: "post",
        url: url,
        cache: false,
        data: "id="+id+"&action="+action+"&str="+str+"&t="+tmp.toString(38),    
        success: function(data){
            if(data=="0"){
                obj.src = "/images/yes.png";
            }else if(data=="1"){
                obj.src = "/images/no.png";
            }else{
                alert("参数出错");
            }
        }
    });
}

前台调用代码

index.php

<?
$nns1 = $row[mstatus]== 0?"/images/yes.png":"/images/no.png";
?>
<img src="<?=$nns1?>" style="cursor:pointer;" onclick="toggle('operate_do.php','ajStatus',this,1,'<?=$row[id]?>')" />

 数据库操作代码

operate_do.php

<?require('includes/global.php');?>
<?
    $action = $_REQUEST["action"];
    
    switch($action){
        case "ajStatus":
            header("Cache-Control: no-cache, must-revalidate");
            header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

            $id=$_REQUEST["id"];
            $str=$_REQUEST["str"];

            switch ($str){
                case 1:
                    $table ="map";
                    break;
                case 2:
                    $table ="map2";
                    break;
            }
            
            $cs=mysql_query("select mstatus from ".$table." where id=".$id."",$dbh);
            if(mysql_num_rows($cs)>0){
                $row=mysql_fetch_array($cs);
                $mstatus=$row[mstatus];
                if($mstatus == 1){
                    mysql_query("update ".$table." set mstatus=0 where id=".$id."",$dbh);
                    echo "0";
                }else if($mstatus == 0){
                    mysql_query("update ".$table." set mstatus=1 where id=".$id."",$dbh);
                    echo "1";
                }
            }
            break;
    }
?>
