Yii2 form event Ajax submission implementation method
这篇文章主要介绍了Yii2表单事件之Ajax提交实现方法,结合实例形式分析了Yii2框架中ajax提交的具体实现技巧,需要的朋友可以参考下
本文实例讲述了Yii2表单事件之Ajax提交实现方法。分享给大家供大家参考,具体如下:
前言
Yii2 现在使用 JS 都必须要注册代码了。
要实现 Ajax 提交,有两种方法。一是直接在 ActiveForm 调用 beforeSubmit 参数,但是个人认为这样没有很好的把 JS 和 HTML 分开,所以我们这篇文章主要介绍第二种方法 - 外部写 JS 方法。
表单部分
<?php $form = ActiveForm::begin([ 'id' => $model->formName(), 'action' => ['/apitools/default/index'] ]); ?>
Ajax
<?php $js = <<<JS // get the form id and set the event $('form#{$model->formName()}').on('beforeSubmit', function(e) { var \$form = $(this); // do whatever here, see the parameter \$form? is a jQuery Element to your form }).on('submit', function(e){ e.preventDefault(); }); JS; $this->registerJs($js);
如果你使用了 JsBlock,你还可以这样写:
<?php JsBlock::begin() ?> <script> $(function () { jQuery('form#apitool').on('beforeSubmit', function (e) { var $form = $(this); $.ajax({ url: $form.attr('action'), type: 'post', data: $form.serialize(), success: function (data) { // do something } }); }).on('submit', function (e) { e.preventDefault(); }); </script> <?php JsBlock::end() ?>

Title: Methods and code examples to resolve 403 errors in jQuery AJAX requests. The 403 error refers to a request that the server prohibits access to a resource. This error usually occurs because the request lacks permissions or is rejected by the server. When making jQueryAJAX requests, you sometimes encounter this situation. This article will introduce how to solve this problem and provide code examples. Solution: Check permissions: First ensure that the requested URL address is correct and verify that you have sufficient permissions to access the resource.

jQuery is a popular JavaScript library used to simplify client-side development. AJAX is a technology that sends asynchronous requests and interacts with the server without reloading the entire web page. However, when using jQuery to make AJAX requests, you sometimes encounter 403 errors. 403 errors are usually server-denied access errors, possibly due to security policy or permission issues. In this article, we will discuss how to resolve jQueryAJAX request encountering 403 error

MySQL transaction processing: the difference between automatic submission and manual submission. In the MySQL database, a transaction is a set of SQL statements. Either all executions are successful or all executions fail, ensuring the consistency and integrity of the data. In MySQL, transactions can be divided into automatic submission and manual submission. The difference lies in the timing of transaction submission and the scope of control over the transaction. The following will introduce the difference between automatic submission and manual submission in detail, and give specific code examples to illustrate. 1. Automatically submit in MySQL, if it is not displayed

Using Ajax to obtain variables from PHP methods is a common scenario in web development. Through Ajax, the page can be dynamically obtained without refreshing the data. In this article, we will introduce how to use Ajax to get variables from PHP methods, and provide specific code examples. First, we need to write a PHP file to handle the Ajax request and return the required variables. Here is sample code for a simple PHP file getData.php:

Build an autocomplete suggestion engine using PHP and Ajax: Server-side script: handles Ajax requests and returns suggestions (autocomplete.php). Client script: Send Ajax request and display suggestions (autocomplete.js). Practical case: Include script in HTML page and specify search-input element identifier.

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

In order to improve Ajax security, there are several methods: CSRF protection: generate a token and send it to the client, add it to the server side in the request for verification. XSS protection: Use htmlspecialchars() to filter input to prevent malicious script injection. Content-Security-Policy header: Restrict the loading of malicious resources and specify the sources from which scripts and style sheets are allowed to be loaded. Validate server-side input: Validate input received from Ajax requests to prevent attackers from exploiting input vulnerabilities. Use secure Ajax libraries: Take advantage of automatic CSRF protection modules provided by libraries such as jQuery.
