I just have a quick question, im wondering if someone could help me.

I have the following script that someone has written which returns an error if there are no characters in the text field.

I want to modify the script so that it returns an error if there are less than 4 characters, but im not quite sure how.

Current script is as follows:

    if(!isString($.trim(iUsername.val()))){ //If username is not correct
        iUsername.siblings('.error').text('You must enter a username.');
        error = true;
    }

Reset to default

if ($(textId).val().length < 4) { err; }

    tekknolagi's answer did not have isString nor trim. Try the answer as given (but put the parens after val of course).

    You need a () after val. After fixing it, it will be a +1.
