Limit number of characters

Restricts the number of characters allowed in text fields whose keys contain a specific keyword.

(function () {
    // Define a form key and type
    let formKey = "Key";
    let formType = "textForm";
    // Define characters number limit
    let symbolsLimit = 10;
    let doc = Api.GetDocument();
    let forms = doc.GetAllForms();

    for (let form of forms) {
        if (form.GetFormType() === formType && form.GetFormKey() === formKey) {
            let input = form.GetText();
            // Set a tip text to warn a user
            form.SetTipText("Number of symbols should be less than " + symbolsLimit);
            form.SetCharactersLimit(symbolsLimit);
        }
    }
})();
