TN8 Item Styleguide ::: Text Entry

Text Entry - with Filtering

Enforcing specific characters in a <textEntryInteraction> is easy. All that needs to be done is to set the patternMask attribute to a valid RegEx expression and we'll enforce that expression. In your RegEx expression, you leave off the start line ^ and end line $ delimiters.

Here is a complete textEntryInteraction with a limit of 10 characters, placeholderText, and a patternMask that restricts input to only alphabetic characters (no numeric characters permitted).

<textEntryInteraction expectedLength="10" patternMask="[A-Za-z]+" placeholderText="foo~~Only 10 alphabetic characters permitted" responseIdentifier="RESPONSE"/>

    <p>Identify the missing word in this famous quote from Shakespeare's Richard III.</p>		
    <blockquote>
      <p>
        Now is the winter of our discontent<br/>
        Made glorious <textEntryInteraction expectedLength="10" 
        placeholderText="foo~~Only 10 alphabetic characters permitted" patternMask="[A-Za-z]+" 
        responseIdentifier="RESPONSE"/> by this sun of York;<br/>
        And all the clouds that lour'd upon our house<br/>
        In the deep bosom of the ocean buried.
      </p>
