If you're a frontend developer looking to enhance user experience on your website by triggering Parsley validation without having to submit a form, you're in the right place. Parsley.js is a fantastic validation library that allows you to easily validate form fields using data attributes. However, by default, Parsley validation occurs upon form submission. In this article, we'll walk you through how you can trigger Parsley validation at your command without needing to submit the form.
One way to achieve this is by leveraging the power of Parsley's API. By tapping into the API, you can programmatically trigger validation whenever you desire. Let's dive into some practical steps to make this happen.
Firstly, ensure you have included the Parsley library in your project. You can either download and include the library from the official Parsley website or use a package manager like npm to install it. Once you have Parsley set up in your project, make sure you have marked the form fields you want to validate with the appropriate Parsley attributes.
Next, let's add a bit of JavaScript magic to trigger the validation. Suppose you have a button on your page that you want to use to start the validation process. You can attach an event listener to this button and, upon clicking it, manually trigger the validation for the specified fields.
Here's an example of how you can achieve this using jQuery:
$('#validateButton').on('click', function() {
$('#yourForm').parsley().validate();
});In this code snippet, we're listening for a click event on an element with the ID of `validateButton`. When the button is clicked, we're telling Parsley to validate the form associated with the selector `#yourForm`.
Now, when a user interacts with your page and clicks the designated button, Parsley will spring into action, validating the form fields in real-time without requiring a traditional form submission.
Another handy feature that you can leverage is the option to specify which fields you want to validate. By passing a CSS selector to the `validate` method, you can target specific form fields to validate, giving you even more control over the validation process.
In conclusion, by using Parsley's API and a sprinkle of JavaScript, you can trigger form validation at your discretion, providing a seamless user experience on your website. This approach allows you to customize when and how validation occurs, empowering you to create a more interactive and user-friendly interface. So go ahead, experiment with triggering Parsley validation without the need to submit a form, and elevate the validation experience on your web projects. Happy coding!
