Alternative to Using AJAX in SuiteScript

AJAX or Asynchronous Javascript and XML is a technique that allows developers to retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page. This uses XMLHttpRequest (XHR), a DOM API that can be used by JavaScript and other web browser scripting languages to transfer XML and other text data between a web server and a browser (as described in A good application is when there's a need to include third party CAPTCHA (see capabilities in a Suitelet designed to be the replacement for an online form.

It is not possible to use the XMLHTTP object in Netsuite due to cross-domain scripting security constraints imposed by all browsers. What can be used instead is the nlapiRequestURL which works in both client and server SuiteScript and one of it's parameters  includes an optional callback function called when the request is completed (Client SuiteScript only). This provides equal functionality as offered by the AJAX approach. 

Here is a sample code accessing the External URL of another Suitelet:

function sendRequestNetsuiteWay()
       var resp = nlapiRequestURL( "http://external_url", null, null, handleResponseNetsuiteWay );

function handleResponseNetsuiteWay(response)
       if (response.getCode() == 200)
              var xmlText = response.getBody();
              var xmlHTTPReq = nlapiStringToXML( xmlText );
              var msgNode = nlapiSelectNode( xmlHTTPReq, "//*[name()='mynode']" );
              var returnedVal  = nlapiSelectValue( msgNode, "//*[name()='mynodevalue']"  );
              alert( "Staus is..."+ response.getCode());


Note: nlapiRequestURL does not work work on online forms.
