Pass Value from Suitelet to Suitelet

1. Create and Deploy a client script with the following code (Customization > Scripting > Scripts > New > Client):

ID: customscript_lab_client

function openSuitelet(){ var url = nlapiResolveURL('SUITELET', 'customscript_lab_suitelet2', 'customdeploy1'); url += '&custpage_param1=' + nlapiGetFieldValue('custpage_param1'); window.open(url);}

2. For Suitelet #1, create a form with a button and set the client script and its function to the button (Customization > Scripting > Scripts > New > Suitelet):

ID: customscript_lab_suitelet1
function suitelet1(request, response){ var form = nlapiCreateForm('Suitelet 1'); form.addField('custpage_param1', 'text', 'Param 1'); form.setScript('customscript_lab_client'); form.addButton('custpage_openform', 'Pass Parameters', "openSuitelet"); response.writePage(form);}

3. Retrieve the field value in Suitelet #2 (Customization > Scripting > Scripts > New > Suitelet):

ID: customscript_lab_suitelet2

function suitelet2(request, response){ response.write(request.getParameter('custpage_param1'));}

When the button in Suitelet #1 is clicked, the client script attached to it will retrieve the value of the custom field and append it to the URL of Suitelet #2.  When the new window containing Suitelet #2 opens, the parameter can then be retrieved through the query string.
