Syntax and Behavior Differences

Examples of Syntax and Behavior Differences

JScript.NET code example	JavaScript code example	Comments
DeviceType.toString() == "Desktop" DeviceType == "Desktop"	DeviceType.toString() == "1" DeviceType == "Desktop"	toString() for enums returns it's integer value, not name.
f('q1').values().toString() == "1, 2" ^f('q1').values()^ returns "1,2"	f('q1').values().toString() == "System.Object[]" ^f('q1').values()^ returns "System.Object[]"	SurveyArrayList no longer exists, so standard .NET array is used. String representation of standard .NET types cannot be changed.
f('q1')['1'] f('q1')('1') f('q1').get_Item('1') Request.Form['q1'] Request.QueryString["test"] UserParameters[paramName]	f('q1').item(1) f('q1').item(1) f('q1').item(1)Request.Form.item('q1') Request.QueryString.item('test') UserParameters.item(paramName)	item() instead of .NET indexer [].
var h = new Hashtable() DateTime.Now HttpContext.Current.Response	N/A	.NET CLR types not supported.
var o : Date = new Date() function ImagenesURL():String { return '' }	var o = new Date() function ImagenesURL() { return '' }	No strict types declaration.
var s = new Set() var s = new SurveyArrayList() var h = new Hashtable()	var s = set() var s = [] var h = {}
GetCatiRespondentUrl(String questionId, params String[] @params)	GetCatiRespondentUrl(String questionId GetCatiRespondentUrl(String questionId, string[] @params)
GetRespondentUrl(String questionId, params String[] params)	GetRespondentUrl(String id) GetRespondentUrl(String id, Boolean isCallBlock, String userParameter, String[] params)
UserParameters[paramName]	UserParameters.item(paramName)
SetPanelistCredit(Int32 credit, String comment, String sectionId)	SetPanelistCreditBySectionId(Int32 credit, String comment, String sectionId)
SetPanelistCredit(Int32 credit, String comment, Int32 panelistId)	SetPanelistCreditByPanelistId(Int32 credit, String comment, Int32 panelistId)
SetPanelistCreditWithCustomVariables(Int32 credit, String comment, String sectionId, String[] fieldNames, String[] fieldValues)	SetPanelistCreditWithCustomVariablesBySectionId(Int32 credit, String comment, String sectionId, String[] fieldNames, String[] fieldValues)
SetPanelistCreditWithCustomVariables(Int32 credit, String comment, Int32 panelistId, String[] fieldNames, String[] fieldValues)	SetPanelistCreditWithCustomVariablesByPanelistId(Int32 credit, String comment, Int32 panelistId, String[] fieldNames, String[] fieldValues)
N/A	Cookies
N/A	CreateCookieObject(String name, String value)
IsNet(object quadIP, object quadNet, object quadMask)	N/A

	Jscript.NET	JavaScript	Comments
Catching exceptions	{ f('invalid-question-id') } catch { }	f('invalid-question-id')	JavaScript engine invocation exception cannot be caught.

Additional Syntax and Behavior Differences

In Forsta scripting, arrays cannot be automatically converted to strings using the caret (^) operator.

This limitation affects functions such as domainValues(), domainLabels(), categories(), and categoryLabels(), which return arrays.

To use these functions within surveys, you must first convert the arrays to strings using the .toString() method.

For Example:

var valuesArray = domainValues();
var valuesString = valuesArray.toString();

Differences between Jscript.Net code and JavaScript code for Offline Mobile Apps (CAPI, AskMe):

	Jscript.NET code	JavaScript code	Comments
Referencing a COMPOUND question code:	f(‘Q1’)[‘2’] == ‘1’ f(‘Q1’)[‘2’].set(‘1’)	f(‘Q1’).item(‘2’) == ‘1’ f(‘Q1’).item(‘2’).set(‘1’)	Differences: item() instead of .NET indexer []
Numeric lists and use of .values()	SUM(f(‘Q1’)) SUM(f(‘Q1’).values())	SUM(f(‘Q1’).values())	Differences: .values() now required
Creating a set object	var s = new Set()	var s = set()
Creating an array	var a = new Array(1,2,3,9,10);	var a = ['1','2','3','9','10'];
