How to introduce tp5 jquery

When using the TP5 framework for front-end and back-end separation development, it is often necessary to use jQuery, a JavaScript library, to achieve interactive effects on the page. So, how to correctly understand and introduce jQuery in TP5? This article will introduce in detail how TP5 introduces jQuery.

1. Correct understanding of jQuery

Before introducing jQuery, we need to have a correct understanding of the jQuery JavaScript library. jQuery is a JavaScript library that greatly simplifies HTML file traversal, event handling, animation and other operations. It is a very practical front-end development tool. jQuery provides a large number of APIs. These APIs allow developers to directly call jQuery methods to complete some common operations without repeatedly writing a large amount of JavaScript code, thus greatly improving development efficiency.

2. Download jQuery

Download jQuery You can go to the official website (http://jquery.com/) to download. We select the "Download" tab, and then select "Download the compressed, production jQuery 3.6.0". The jQuery version number here can be selected according to actual needs. After the download is complete, we unzip the compressed package to our project folder.

3. Introducing jQuery

After unzipping jQuery into our project folder, we need to introduce jQuery into the page so that we can use the methods provided by jQuery in the page .

In TP5, we can use the following two methods to introduce jQuery:

1. Introduce jQuery in the layout file

If we want every page to have jQuery method, you can introduce jQuery in the layout file of the template. Perform the following operations in our PHP file (layout.php):

<!-- 引入 jQuery -->
<script src="__PUBLIC__/jquery/jquery-3.6.0.min.js"></script>

Among them, __PUBLIC__ is a constant in the TP5 framework used to point to the static file directory, usually the default value is "/ public/”.

In this way, in each view file that uses a template, we can directly use the methods provided by jQuery.

2. Introduced in the view file that needs to use jQuery

In some cases where jQuery only needs to be used on partial pages, we can only use jQuery in the view file In order to avoid the problem of introducing multiple jQuery libraries into one page.

Do the following in our PHP file (index.php):

<!-- 引入 jQuery -->
<script src="__PUBLIC__/jquery/jquery-3.6.0.min.js"></script>

In this way, we can use the methods provided by jQuery in the index.php file. Such as:

<script>
    $(document).ready(function(){
        // 等待 DOM 完成加载后执行
        $("button").click(function(){
            // 点击 button 执行方法
            $("body").css("background-color", "red");
        });
    });
</script>

4. Conclusion

Through the above two methods, we can easily introduce jQuery into TP5 and use the methods provided by jQuery. It is recommended that when developing a project, the layout introduction method should be used as much as possible to avoid introducing the jQuery library multiple times in one page, thereby improving page loading efficiency. I hope this article is helpful to all readers.
