Invoke ColdFusion function using AJAX

If you have multiple functions in your cfm(even if you don’t), put them in a cfc.
Then you can use the following url pattern to invoke a specific method.

cfc named myEntityWS.cfc

<cfcomponent>
  <cffunction name="updateDescription" access="remote" returntype="string">
    <cfargument name="value" type="string" required="yes">
    <cftry>
      your code here
    <cfcatch>
      <cfoutput>
        #cfcatch.Detail#<br />
        #cfcatch.Message#<br />
        #cfcatch.tagcontext[1].line#:#cfcatch.tagcontext[1].template#
      </cfoutput>
    </cfcatch>
    </cftry>
  </cffunction>
</cfcomponent>

Javascript

$.get('myEntityWS.cfc?method=updateDescription&value=someValue');
