Can jquery be used with layui?

jQuery and layui are two different front-end frameworks. Their design ideas and implementation methods are different, so some conflicts and compatibility issues may occur during use. However, jQuery and layui do work together, and they are widely used in many projects.

Before discussing how to use jQuery and layui at the same time, we need to first understand the basic characteristics of these two frameworks.

jQuery is a JavaScript library. Its main function is to encapsulate common JavaScript operations and provide many simple, flexible, and efficient APIs. The focus of jQuery is on DOM operations and event processing, allowing developers to more conveniently operate HTML document elements, quickly respond to user operations, and achieve interactive effects.

layui is a modular front-end framework based on jQuery. It provides a set of beautiful, easy-to-use, efficient, responsive UI components and some commonly used functional modules, such as forms, paging, uploads, etc. . The characteristics of layui are that it is lightweight, easy to use, flexible and scalable.

Although their functions and designs are different, they are all used by introducing the corresponding JavaScript files. When using jQuery and layui on the same page, there may be conflicts in some global namespaces, variables, event listeners, etc. Therefore, we need to pay attention to some usage issues.

1. Introduction sequence

When using jQuery and layui, make sure to introduce the jQuery library first, and then the layui library. Because layui depends on jQuery, if jQuery is not introduced first, the layui module will not be usable.

2. Avoid global name conflicts

In order to avoid global namespace conflicts, we can try to use the safe $ symbol provided by jQuery when using jQuery. LayUI symbols are used in layui to distinguish and isolate the namespaces between modules.

For example:

// Using jQuery and layui

// Isolate jQuery's $ symbol through an anonymous function to avoid conflict with layui's symbol
<script></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>(function ($) { // 使用 jQuery 的 $ 符号，不受 layui 的影响 $(function () { // your jQuery code }); })(jQuery);</pre><div class="contentsignin">Copy after login</div></div><p>&lt ;/script></p> <p>// Code for using layui<br><script><br>layui.use(['laypage','layer'], function(){<br> // your code<br>});<br></script>

3. Avoid event conflicts

If the same type of event is bound multiple times in the same page , event conflicts may occur, resulting in the failure of functions on some pages. At this time, we need to avoid event conflicts and solve them by using event namespaces. Event namespace refers to setting a specific name for the same type of event to distinguish it from other events.

For example:

// Limit the event namespace to the 'myNamespace' namespace
$(document).on('click.myNamespace', function() {
// do something
});

4. Avoid style conflicts

Using jQuery and layui at the same time will also face a problem: style conflicts. Because layui provides its own CSS style library, its styles may conflict with the existing style library in the page, causing the page display to fail. In order to avoid this from happening, we need to design our own CSS styles reasonably and use the style override tool class provided by layui to make changes.

In short, when using jQuery and layui, you need to pay attention to issues such as global namespace, variables, event monitoring, etc. Adopting reasonable programming standards and following the above recommended methods can avoid many conflicts and compatibility issues, allowing us to make full use of the advantages of jQuery and layui to better develop and optimize web pages.
