When you encounter the problem of "jquery.js is not fully introduced" in the browser, it may cause the web page functions to not work properly or the display to be incomplete. Before we can solve this problem, we need to understand why this happens and how to deal with it effectively.

Cause analysis

The incomplete situation when introducing jQuery may be caused by the following reasons:

1. Network loading problem: The file may not be fully loaded due to unstable network or delayed server response.
2. File path error: It may be that the path of the imported jQuery file is incorrect, causing it to fail to load completely.
3. Version mismatch: It may be that the introduced jQuery version is incompatible or has a bug, causing some files to not be loaded.

Processing method

In response to the above possible reasons, we can take the following measures to solve the problem of "incomplete introduction of jquery.js":

1. Handling network loading problems:

   When you encounter network loading problems, you can try to refresh the web page or wait for a period of time to load again to ensure network stability.

2. Check the file path:

   Confirm whether the imported jQuery file path is correct. You can check whether it is by checking the console panel of the browser developer tools. If there is a 404 error, find the cause of the file path error and correct it.

   <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

   Copy after login

3. Update jQuery version:

   If the jQuery version is incompatible or has a bug that causes incomplete loading, you can try to update to the latest version. jQuery comes to the rescue.

   <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

   Copy after login

Sample code

A complete sample code is provided below, demonstrating how to correctly introduce jQuery and handle possible problems:

jQuery示例


<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

<script>
// 使用jQuery编写js代码
$(document).ready(function(){
    // 代码逻辑
    $("h1").css("color", "red");
});
</script>

In In this example, we load the jQuery library by introducing the jQuery CDN link, and use jQuery syntax to modify the style of the title on the page. Ensure that the imported jQuery path is correct and the version is compatible to avoid the problem of "incomplete introduction of jquery.js".

Through the above measures and sample codes, we hope to help readers solve the problem of "incomplete jquery.js import" in the browser and allow the web page functions to run normally.
