Good morning. Is there a way to pass a value from an OnClick Javascript Detail Page Button to a Controller other than the controller that the button is on?

This is my JavaScript:

{!REQUIRESCRIPT("/soap/ajax/26.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/26.0/apex.js")}

var engID=window.sfdcPage.entityId
var postType="statement of work";   

window.location="https://rsidemo1-dev-ed--c.na24.visual.force.com/apex/VfFilePost?scontrolCaching=1&id="+engID;

I want to assign postType to a variable in the controller of the VfFilePost Page. I am new to Salesforce and programming. Any help is appreciated.

You could pass it as an encoded URL parameter:

{!REQUIRESCRIPT("/soap/ajax/26.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/26.0/apex.js")}

var engID=window.sfdcPage.entityId
var postType="statement of work";   

window.location="https://rsidemo1-dev-ed--c.na24.visual.force.com/apex/VfFilePost?scontrolCaching=1&id="+engID+"&postType="+EncodingUtil.urlEncode(postType, 'UTF-8');

And then retrieve and decode it in your recipient controller:

String rawPostType = ApexPages.currentPage().getParameters().get('postType');
String postType = EncodingUtil.urlDecode(rawPostType, 'UTF-8');

  • I'm getting an error. EncodingUtil is not defined. Do I have the correct requirescript notation? Commented Sep 25, 2015 at 13:07
  • The second excerpt is for an Apex controller. Were you not talking about Apex controllers? What type of controller did you mean? Commented Sep 25, 2015 at 13:14
  • The Apex controller extension for the VfFilePost Page. Commented Sep 25, 2015 at 13:19
  • You should be able to run the second excerpt within the controller extension. EncodingUtil is a standard Apex library. Commented Sep 25, 2015 at 13:21
  • Were you able to get it working in the end? Commented Sep 25, 2015 at 13:55
