I am trying to mark a checkbox via a javascript button, i.e. update it as true. The checkbox is a field (Precisa_Cota_o_Frete__c) in the opportunity, but I want the button to work from the quote detail page. Here is the code I've got so far, but I am getting an error message from Salesforce:



 var opportunity = sforce.connection.query("Select Opportunityid From Quote where id = '{!Quote.Id}'");
 var myJob1 = new sforce.SObject("Opportunity"); 
 myJob1.Id = opportunity; 
 myJob1.Precisa_Cota_o_Frete__c = "true"; 
 var result = sforce.connection.update([myJob1]); 

Error Message: A problem with the OnClick JavaScript for this button or link was encountered:

{faultcode:'soapenv:Client', faultstring:'Unexpected element {urn:partner.soap.sforce.com}done during simple type deserialization', line:'1015', column:'29', sourceURL:'https://na23.salesforce.com/soap/ajax/20.0/connection.js', }

It already does work without the var opportunity part on the opportunity page, there just defining the Id by putting myJob1.Id = "{!Opportunity.Id }";

Any ideas? Is that cross-referencing at all possible?

  • Why you try to use JS in this example? Jun 18, 2015 at 12:12
  • I couldn't find a way to mark a checkbox via URL, if that is the question. Jun 18, 2015 at 12:17
  • As I understand you mean mark/update in database Jun 18, 2015 at 12:19
  • Yes, that is correct. - I want to update the checkbox field Precisa_Cota_o_Frete__c to the value true. The field is in the Opportunity. The button should work from the quote page. Jun 18, 2015 at 12:21
  • If you don't want to write too much javascript, you could write an apex method with the webservice annotation, and then just use javascript to call the function.

This should be possible. Try removing the quotation marks around true in your code. The field will be expecting a boolean value, and you're attempting to assign a string.

So the line in question becomes:

myJob1.Precisa_Cota_o_Frete__c = true; 
  • The way I programmed the button actually works already on the opportunity, it seems to have accepted it with quotation marks there, although your comment makes sense! My difficulty is how to cross-reference quote/opportunity correctly. Jun 18, 2015 at 12:55

Java script button is also quite nice solution, but I think you should try page + controller. Create vf page with controller that will contain method to update parent opportunity - define this action in page. Call page from button and add button to quote layout.

I think it is safer to use standard solutions than JS.

  • I've always been torn between which is the best way of doing this. Using a visualforce page feels like the more proper "salesforce" way to do it, but on my org, I feel that it is noticeably slower than javascript.

Change your 6 line to:

myJob1.Id = opportunity.records[0].Opportunityid;

The sforce.connection.query method doesn't return the specified field, but rather a List<SObject>.
