序言
为了让用户有更加良好的体验,在操作成功或者失败后,来个提示并跳转页面,我就在Yii2上实现了这一个效果。在写这个跳转提示页的时候,找资料我发现网上关于这方面的中文资料真的很少,大家也都共享下吧!
需求分析
1、用户在操作成功或者失败后,来个提示并跳转页面。2、使用这种方式$this->success(),$this->error()调用(仿造Yii2自带 $this->render()加载页面的方式)。
效果图
样式有点丑,但是功能是好的,要是不喜欢这样式大家可以自行美化一下!
代码分析
1、在控制器的基类Controller.php里边增加两个方法,这么写:
/** * 通用成功跳转 * @param unknown $url 成功后跳转的URL * @param number $sec 自动跳转秒数 * @return Ambigous <string, string> */ public function success($url= [] ,$sec = 3){ $url= empty($url)? ['/admin/main']: $url; $url= /yii/helpers/Url::toRoute($url); return $this->renderPartial('../base/msg',['gotoUrl'=>$url,'sec'=>$sec]); } /** * 通用错误跳转 * @param string $msg 错误提示信息 * @param number $sec * @return Ambigous <string, string> */ public function error($msg= '',$sec = 3){ return $this->renderPartial('../base/msg',['errorMessage'=>$msg,'sec'=>$sec]); }
2、在loginviewsbase的下面建立一个命名为msg.php的页面,代码如下:
<?php/* @var $this yii/web/View *//* @var $name string *//* @var $message string *//* @var $exception Exception */use yii/helpers/Html;?><div class="site-error"> <div class="alert alert-danger page-none-alert"> <p> <?php if(isset($errorMessage)):?> <span class="glyphicon glyphicon-remove-sign text-danger"></span> <span class="btn-lg text-danger"><?php echo '操作出错啦!' ?></span> <?php echo '<p>'.$errorMessage.'</p>';?> <?php else:?> <span class="glyphicon glyphicon-ok-sign text-success"></span> <span class="btn-lg text-success">恭喜!操作成功!</span> <?php endif;?> </p> <p class="text-muted">该页将在3秒后自动跳转!</p> <p> <?php if(isset($gotoUrl)):?> <a href="<?php echo $gotoUrl?>">立即跳转</a> <?php else:?> <a href="javascript:void(0)" onclick="history.go(-1)">返回上一页</a> <?php endif;?> </p> </div> <style> .page-none-alert{margin: 100px 0 !important; text-align: center !important; font-size: 30px !important;} </style> </div><script> <?php if(!isset($gotoUrl)):?> setInterval("history.go(-1);",<?php echo $sec;?>000); <?php else:?> setInterval("window.location.href='<?php echo $gotoUrl;?>'",<?php echo $sec;?>000);<?php endif;?></script>
3、完成以上步骤之后就可以在login模块下的控制器里边直接调用了,调用方式如下:
成功的调用方式: return $this->success([‘/site/login’]);
失败的调用方式: return $this->error(‘数据修改失败!’);
常见问题
1、跳转提示的JS写在如下我注释的地方了,写在那的话就不起作用了,得写在外面才行。
<?php $this->beginBlock('JUMP_JS')?> (function(){ //跳转提示的JS写在这了。不能写在这,写在这里就不起作用了。 });<?php $this->endBlock(); $this->registerJs($this->blocks['JUMP_JS'],/yii/web/view::POS_END);?>

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
