rails 6 TypeError: $(...).tooltip is not a function
Sure! Here is a response without any personal words or sentences at the beginning and end:
Explanation of TypeError: $(...).tooltip is not a function in Rails 6
The error message "TypeError: $(...).tooltip is not a function" indicates that there is a problem with the code related to the
tooltip
function in jQuery. This error typically occurs when thetooltip
function is being called on an element that does not have this function available.In Rails 6, jQuery is not included by default and is instead replaced by StimulusJS as the default JavaScript framework. This means that you need to manually include jQuery if you want to use it in your Rails 6 application.
To resolve this error, you can follow these steps:
a. Make sure that you have included the jQuery library in your Rails 6 application. You can do this by adding the following line to your application.js file:
ruby
//= require jquery
b. If you are using the Webpacker gem in Rails 6, you will need to install the jQuery package using Yarn or npm. Run the following command in your terminal:
ruby
yarn add jquery
c. After installing the jQuery package, you need to import it in your application.js file. Add the following line to the top of the file:
ruby
import $ from 'jquery';
d. Save the changes to your application.js file and restart your Rails server for the changes to take effect.
Once you have included and imported jQuery correctly, the
$(...).tooltip
function should be available and the "TypeError: $(...).tooltip is not a function" error should be resolved.If you are still encountering the error after following these steps, make sure that you have correctly referenced the element on which you are calling the
tooltip
function. Ensure that the element is present in your HTML and has the necessary attributes and classes required for thetooltip
function to work.
I hope this explanation helps you understand the cause of the error and how to resolve it in Rails 6. Let me know if you have any further questions.
