Checking If/Else Condition in Alert Message using React

by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we're going to see how to check if/else condition in alert message using React with simple steps. Here we're using if/else condition to handle the user input whether given their inputs or not. In this case, the system checks whether the user given their input if the user given his/her name in the text box it doesn't shows any alert message to the user. Otherwise, the user forget to give their name in the text box it shows an alert message ("Name should not be empty"). It helps us to fill the forms or applications without leaving any blank text fields. To implement this task, use the ready-made code snippet below by just copying the code and paste it in your IDE with React library. Explore more top trending libraries and code snippets on kandi.
