It seems that you are encountering an issue where the symbol "$" is not defined when using the $.ajax function. This typically occurs when the jQuery library is not properly loaded or included in your project.
To resolve this issue, you need to make sure that you have included the jQuery library before using any jQuery functions. You can do this by adding the following code to your HTML file:
```html
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
```
Make sure to place this script tag before any other JavaScript code that relies on jQuery.
If you have already included the jQuery library and are still experiencing this issue, please check if there are any conflicts with other JavaScript libraries or frameworks that you are using. In some cases, conflicts can cause the $ symbol to be overwritten or undefined.
You can also consider using the `jQuery.ajax` function instead of `$.ajax` as a workaround, as it is an equivalent way to make AJAX requests using jQuery.
I hope this helps! Let me know if you have any further questions.
