Is there a quick way of counting the number of words in a JIRA customfield?

Is there a way to count the number of words in a text field on JIRA? I know we can count the length by either JS or workflow validation using script runner.

JS

<script type="text/javascript">
document.getElementById("customfield_xxxxxx").maxLength=50;
</script>

Script Runner

cfValues["Name of Field"]?.length() <= 50

With Scriptrunner you can use

wordcount = cfValues["Name of Field"]?.split(/\S+/).size()

if "words" are text blocks separated by one or more spaces, tabs or new lines. ([ \t\n\x0B\f\r]).

Works a treat. Thank you.

I've modified your code to get this working in Behaviors which is easier to maintain and more user friendly.

short_description = getFieldByName("Short Description")
short_descriptionValue = short_description.getValue()?.split(/\S+/).size()
if (short_descriptionValue >=6)
{ short_description.setError("BLA BLA BLA") }
else 
{short_description.clearError()  }
