Calling activity from HTML in section
Hi, I am trying to call an activity and pass parameter to it from java script in a Section. I am not been able to do this. I'm using below code:
<script>
var varNameOnCard = "Biswajit";
oSafeURL =null;
var oSafeURL = new SafeURL("Grp-Data-Fin-PaymentAccount-Card.PostAuthSemafoneTest",getReqURI());
oSafeURL.put("NameOnCard", varNameOnCard )
//var strReturn = httpRequestAsynch(oSafeURL.toURL(),null, 50, 100);
//pega.util.Connect.asyncRequest('GET', oSafeURL.toURL(),'');
var strResponse = httpRequestAsynch(oSafeUrl.toURL(),"post");
</script>
However if I use the below JSP, activity is invoked correctly but I can't pass the parameter on to it from java script code. So if any body can please help understand why the former is not working. Many thanks for help.
<%
String strNameOnCard = "Biswajit";
ParameterPage newParams = null;
HashStringMap keys= null;
newParams = tools.getParameterPage();
newParams.putString("NameOnCard",strNameOnCard);
keys = new HashStringMap();
keys.putString("pxObjClass", "Rule-Obj-Activity");
keys.putString("pyClassName", "Grp-Data-Fin-PaymentAccount-Card");
keys.putString("pyActivityName", "PostAuthSemafoneTest");
tools.doActivity(keys, tools.getPrimaryPage(), newParams);
%>

What version of Pega are you using?
The two statements below should be fixed:
oSafeURL =null;
var oSafeURL = new SafeURL("Grp-Data-Fin-PaymentAccount-Card.PostAuthSemafoneTest",getReqURI());
In the first statement you declare a globally-scoped "oSafeURL" variable but in the next statement immediately declare one that is locally scoped
It the second statement I believe you should begin your URL with "pyActivity=". I could be wrong.
In Pega 7 you can easily call an Activity from the UI but apparently you are looking to do something with the async response yourself within the browser's DOM, or do you simply want to popup a confirm or alert window?

Thanks PEDEL. I can now call the activity from Java Script. We are at Pega 7.1.5.
We are doing a POC to integrate with Semafone. This is just to pass on a success / Failure from Semafone and continue processing in Pega. Thank you.

I have a local errror variable declared in SaveData activity, but its not returning error message . Is there something missed here.
var workURL = new SafeURL("Test-CallActivity.SaveData");
var returnVal = pega.util.Connect.asyncRequest('GET',workURL.toURL(),null);

Modify SaveData activity to return local error variable to java script code.
You can do this using Show-Property activity method.
Then implement callback in the JS code to read the returned value as shown below -
var workURL = new SafeURL("Test-CallActivity.SaveData");
var callback = {
success: function(oResponse){
// Read local error variable
var returnVal = oResponse.responseText;
},
failure: function (oResponse) {
}
};
var request = pega.util.Connect.asyncRequest('POST', workURL.toURL(),callback, null);

Thanks for your suggestion.
Above recommendation works fine in IE , the issue we are having now is with Firefox and Chrome. Callback is not working other than IE browser or wiith local error msg variable having show-property

Hi Sudhakar,
Callbacks, asynchRequest works perfectly across all browsers. To verify, please put loggers in your activity and alerts inside callback's SUCCESS block.
Please check if other JS functions and variables you have used are cross browser compatible.
