Javascript Errors in Safari

[silasjmatson]

Attempting to use the filters causes an error in Safari, due to NodeList not having a defined `forEach function.

TypeError: this.querySelectorAll('input, select').forEach is not a function. (In 'this.querySelectorAll('input, select').forEach(function (field) {
      if (field.value === '') {
        field.disabled = true;
      }
    })', 'this.querySelectorAll('input, select').forEach' is undefined)
