Case insensitive regular expression validation of text field

[ptrobot]

Unfortunately the Javascript flavor of regex does not support inline modifiers. In other flavors of regex you can use (?i) to ignore case.

A workaround is to edit the json string and add a custom validation:

{
  "label": "Test",
  "tableView": true,
  "validate": {
    "custom": "valid = (/^.*\\.pdf$/i.exec(input) === null) ? 'Wrong format!' : true;"
  },
  "key": "test",
  "type": "textfield",
  "input": true
}
