How to use jQuery to onsubmit and check if the value is 2 - 5 characters?

Question

Let\'s say I have a text field:

Username: 

Answer 1

You can check the value of the input field with user.val() and the length of the string with user.val().length.

That way you can do something like this:

if(user.val().length < 2 || user.val().length > 5) {
    console.log('test')
}
