If a user doesn't choose any value 1-5 and still hits submit, is there a code to prevent them from doing so?

I tried to write javascript code where it would be impossible for a user to hit submit button if they don't choose any value 1 - 5 to give rating.

In that case, they wouldn't be able to proceed even if they pressed submit, because there would be an alert displayed, warning them to first choose a value between 1 and 5.

I know there should be an if statement and compare rating to the one we get from buttons as input, but I couldn't complete the code. The furthest I got was to be able to display this alert, but it was then displayed each time I pressed submit, instead of only when I didn't choose any value.

You should probably make use of a boolean variable.

First declare lets say buttonPressed = false.

Change it to true in your click event listener for the buttons.

Create an if else statement in the click event for the submit button.

In the if-statement write if(buttonPressed === true) or if(buttonPressed) which is the same and in the if block write out your code.

In the else statement you can either apply an alert (this is not very pretty though) or attach lets say a red error message on the container that lets the user know they need to press one of the buttons.

Good Luck!

@RalfiSlask This was such an elegant solution! I implemented it right away, and it worked like a charm. I agree displaying a simple alert message looks inelegant (and rather aggressive indeed), but for my demo purposes it served.

I can't believe I completely forgot about the power of boolean values.

Thank you so much for this, it was short, simple and efficient!
