A very good W3school tutorial can be found here.

Javascript – restrictions on the number of letters allowed in a word game input field

The alert line activates it and the input field locks, preventing the player from entering text.

I have added the restriction of a maximum of five letters, but when I add a minimum using ||, this restriction blocks me and I cannot enter the text.I need it to prevent the player from entering words less than 5 letters.

I need help, I’m a beginner.

    That’s expected, because you are utilising input event. If I understand correctly, you are trying to use (input.value.length<5||input.value.length>5) for this. In this case, the input event will be fired with every keypress and the if statement will be executed everytime till the length becomes 5. That’s because input.value.length<5 will be true, till the length is not equal to 5.

    What you can do is, use change event instead of input. The change event will be fired when the input is changed and loses the focus or the user presses the enter key. Then the if clause can check for the conditions to determine whether the input is alright or not.

    There you go:

    var x = document.getElementById("myText").maxLength;
