Solving the Can't Type in Form Input Issue in React JS
If you've recently started developing with React JS, you might encounter some frustrating issues, especially when working with forms. One common problem many beginners face is not being able to type in specific input fields of a form. This article explores a specific case scenario and provides a simple solution to it.
The Problem
You might find yourself in a situation where you can type in certain input fields, such as the email and phone fields, but are unable to do so in the first name, last name, or message fields. This discrepancy can leave you scratching your head, wondering what might be wrong with your code.
Understanding the Root Cause
In the example provided, the issue arises from the use of incorrect id attributes in the input fields for first name and last name. Specifically, both fields were assigned the same id value (name), which confuses the event handler and leads to the inability to update the correct data in the state for those fields.
Key Takeaway:
Each input field's id must be unique to ensure that React can correctly identify and update the corresponding state values.
Solution Steps
Here’s how to resolve this issue with a clear step-by-step guide:
1. Change the IDs
