code: function enableJsonValidationCheck(value, isJsonCheckBox) {
    try {
      JSON.parse(value);
      // if this is valid json and is array or object assume we want validation active
      if (value.match(/^\s*[{\[]/)) {

docs: check if given string value is valid json and, if so enable validation
  for given field if this is an json object or array. Do not automatically
  enable validation on numbers or quted strings. May be coincidence that this is json...
  
  @param {string} value string to check if valid json
  @param {string} isJsonCheckBox id string of checkbox element to activate validation
