1、实现效果，操作成功后失败成功自动跳转
2、创建操作成功失败跳转方法CrlBase.php
/**成功后跳转*跳转地址$url* 跳转显示信息$msg* 等待时间$wait* 是否自动跳转$jump*/protected function ok($url=NULL,$msg='操作成功',$wait=3,$jump=1){$code=1;include KJ_CORE.'/tpl/dispatch_jump.tpl';}/**失败后跳转*跳转地址$url* 跳转显示信息$msg* 等待时间$wait* 是否自动跳转$jump*/protected function err($url=NULL,$msg='操作失败',$wait=3,$jump=0){$code=0;include KJ_CORE.'/tpl/dispatch_jump.tpl';}
3、创建跳转模板dispatch_jump.tpl
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<body>
<div class="system-message"><?php switch ($code) {case 1:?><h1>:)</h1><p class="success"><?php echo(strip_tags($msg));?></p><?php break;case 0:?><h1>:(</h1><p class="error"><?php echo(strip_tags($msg));?></p><?php break;
} ?><p class="detail"></p><?php if($jump==1){?><p class="jump">页面自动 <a id="href" href="<?php echo($url);?>">跳转</a> 等待时间： <b id="wait"><?php echo($wait);?></b></p><?php }?>
</div>
<script type="text/javascript"><?php if($jump==1){?>(function(){var wait = document.getElementById('wait'),href = document.getElementById('href').href;var interval = setInterval(function(){var time = --wait.innerHTML;if(time <= 0) {location.href = href;clearInterval(interval);};}, 1000);})();<?php }?>
</script>
</body>
</html>
4、实现跳转操作indexCrl.php
<?php
class indexCrl extends CrlBase {public function index(){$this->ok("index.php?c=index&a=index2",'操作成功,跳转index2');}public function index2(){echo "index2";}
}
