TypeError: $(…).modal is not a function
The error "The $(…).modal is not a function" commonly arises due to incorrect script loading order, where scripts are not arranged in a sequential order that matches their dependencies. Browsers execute scripts in the order they encounter them, and accessing elements in a script before they are available can result in errors. To mitigate this issue, it is crucial to ensure that scripts are arranged in the correct order, with dependent scripts placed below those they rely on, thus preventing such errors from occurring.
Bootstrap : TypeError
For example, bootstrap depends on jQuery , so jQuery must be referenced first. So, you must called the jquery.min.js and then bootstrap.min.js like the following:
Many plugins and CSS components have dependencies on other plugins or libraries. It's crucial to consult the documentation for each plugin to identify any such dependencies. Additionally, please bear in mind that all plugins rely on jQuery, so it's essential to include jQuery in your project before including the plugin files. Ensuring the correct order of inclusion and addressing any dependencies is essential for the proper functioning of these components within your web application.
Multiple jQuery instances
This warning can also appear if jQuery is declared multiple times in your code. When there are multiple jQuery declarations, it can disrupt the functioning of bootstrap.js and other scripts. It's important to ensure that you have only one instance of jQuery in your code to avoid conflicts and ensure proper functionality. If you're working with multiple files and scripts, make sure to consolidate jQuery into a single instance to resolve this issue.
