Issue with JavaScript button: value is undefined

Hi community,

 

I have a JavaScript button that calls successfully an Apex class.

However, now I want to give the Opportunity record as a parameter to my Apex method but it does not work.

(it is a detail page button)

When clicking on the button from the Opportunity, the message I get is:

 

"

A problem with the OnClick JavaScript for this button or link was encountered:
value is undefined

"

 

This is my JS button:

{!REQUIRESCRIPT("/soap/ajax/27.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/10.0/apex.js")}

var opp = sforce.SObject("Opportunity");
var myString = sforce.apex.execute("ClosedDuplicate","myMethod2",{contextOpp:opp});


window.alert(myString);

 

Basically, what I am unable to do is transmit the opportunity record from where the button has been clicked to my Apex method. I hope its is possible. If not can someone give me the script for trasnmitting the record ID?

 

Thanks!

After further diggin, I found a solution thanks to this blog:

Instead of

 

var opp = sforce.SObject("Opportunity");

 

I put:

 

var opp = new sforce.SObject("Opportunity");
opp.id = "{!Opportunity.Id}";

 

That worked....

Hi , 

 

For passing the parameter in such cases to controller, you must use apex:param visualforce component.

 

See the example below,

Thank you, but I am asking for a solution via JavaScript, not Visualforce
