When you're working on web forms, it's common to have multiple submit buttons, but it can be tricky to figure out which one was clicked when the form is submitted. In this article, we'll walk through how to determine which submit button was pressed using the form onSubmit event without resorting to jQuery duplication techniques.
One straightforward and effective way to achieve this is by utilizing the event object that gets passed to the onSubmit function by the browser. By leveraging this event object, we can pinpoint the exact submit button that triggered the form submission action.
To get started, let's review a step-by-step guide on how to implement this solution:
1. First, ensure that your form has all the necessary elements and multiple submit buttons that you want to distinguish between.
2. In your JavaScript code, where you handle the form onSubmit event, access the event object that's automatically passed as a parameter to the event handler function.
3. By examining the event object, you can then identify the target property within the event object, which corresponds to the element that triggered the event. In this case, it will be the submit button that was pressed.
4. Once you've obtained the target element, you can inspect its attributes or properties to differentiate between the various submit buttons in your form. Common attributes like name, id, or value can be useful for this purpose.
5. Based on the unique attributes of the clicked submit button, you can then execute the specific functionality or validation logic corresponding to that button within your onSubmit event handler.
For instance, you could check the name attribute of the submit button to determine the action to take:
function handleFormSubmission(event) {
const clickedButton = event.target;
if (clickedButton.name === 'saveChanges') {
// Logic for handling "Save Changes" button
} else if (clickedButton.name === 'submitForm') {
// Logic for handling "Submit Form" button
}
}By following these steps and identifying the clicked submit button based on its unique attributes, you can efficiently handle multiple submit buttons within a form without the need for duplicating jQuery code or resorting to complicated workarounds.
Remember, understanding how events work in JavaScript and leveraging the event object empowers you to create more dynamic and interactive web forms. This approach not only enhances the user experience but also streamlines your code by eliminating unnecessary duplication.
With this practical guide, you can now confidently tackle the challenge of determining which submit button was pressed in your web form onSubmit event without the need for jQuery duplication. Happy coding!
