sforce.apex.execute invalid or unexpected token

Question

{!REQUIRESCRIPT("/resource/1468830130000/ConnectionJsNoAgent")} 
{!REQUIRESCRIPT("/soap/ajax/29.0/apex.js")} 
var result = sforce.apex.execute("SendSms","callSendWSrvId", "{id'{!CKSW_BASE__Service__c.Id}'}"); 
alert('result '); 
window.location.reload();

I keep getting errors and no matter what i do i cant seem to get it to work. I tried it with a @future @remoteAction and standard methods.

@future (callout = true)
    public static void sendWSrvId(String Id) {
//logic
}

Update: Forgot to mention I' using this in a custom button.

Update 2: Error after switching to webservice

Answer 1

The params object (third parameter to sforce.apex.execute) should be a normal object, not a string. Also, that means your code is malformed.

Here's a corrected version of your JavaScript:

var result = sforce.apex.execute("SendSms","callSendWSrvId", {id: '{!CKSW_BASE__Service__c.Id}'});     
alert(result); 

Answer 2

If you are invoking a method from a Custom button it should be a webService method.

Try this:

Apex Class:

global class SendSms {
        webService static void sendWSrvId(Id recId) {
            //logic
        }
    }

Button code:

{!REQUIRESCRIPT("/resource/1468830130000/ConnectionJsNoAgent")} 
{!REQUIRESCRIPT("/soap/ajax/29.0/apex.js")} 
var result = sforce.apex.execute("SendSms","sendWSrvId", "{recId: '{!CKSW_BASE__Service__c.Id}'}"); 
alert('result '); 
window.location.reload();
