title: How to pass CRM Dynamics 2015 Form data(filed values) to an HTML page which has JavaScript functions
body: <p>I recently acquired a JavaScript API for a  web-phone web client. From CRM I want to launch this client and pass my CRM Form data to it, I have created a custom ribbon button that has to call that HTML Page and pass relevant data to it.</p>
  
  <p>The ribbon button should launch the URL to the web-phone, but at the same time pass parameters to the JavaScript functions in the HTML page, do I use JavaScript action on ribbon or do I use URL action , if I use URL how do I pass data to the JScript function?</p>
  
  <p>To make this clearer I have a Contact entity in CRM which has a mobile number that I want to pass as a parameter to the HTML page that has the JavaScript functions I want to utilize for the web-phone client </p>
