title: Regex unexpected token
body: <p>When I add this regex into validation engine I get a javascript error: "unexpected token", it seems that the regex is wrong because it is underline with red, why? </p>
  
  <pre><code>"time1":{    
     "regex": ^([0-9]|0[0-9]|1[0-3]|2[0-3]):[0-5][0-9]$,
     "alertText": "* Invalid Time"
  }
  </code></pre>
