EscapingHandlebarsexpressions

Handlebarscontentmaybeescaped-i.e.displayedasis,withoutevaluatingtheexpression-bypre-

fixingitwith\(abackslash).Forexample:\{{FieldName}}willshowupintheoutputas{{FieldName}},

insteadofbeingreplacedwiththevalueofthedatafieldFieldName.

Rawblocks-Handlebarsexpressionswithfourcurlybracesatthestartandend-arenotsupported.

Using functions in expressions: Helpers

Note: TheinformationinthisOnlineHelpfocusesontheimplementationofHandlebarsinOL

Connect.ForgeneralinformationaboutHandlebarsandhowtouseit,seethefollowingweb

sites:https://handlebarsjs.com/andhttps://devdocs.io/handlebars.

FunctionsthatcanbeusedinaHandlebarsexpressionarecalledHelpers.

Example: {{dateLongDueDate}}

Inthisexample,dateLongisthenameofoneoftheFormatHelpersinOLConnect,andDueDateisthe

nameofadatafield.Whenthetemplateismergedwithdata,thisexpressionreturnsthevalueofthe

DueDatefield,formattedasalongdate,e.g."February23,2022".

AnythingthatfollowsaHelperinanexpressionispassedtotheHelperasaparameter.

Theparameterdoesn'thavetobeadatafield.ItcanalsobeanotherHelperthatreturnsavalue.Thisis

calledasubexpression.

Example: {{dateLongtoday}}

Inthisexample,todayisthenameofaHelperthatreturnsthecurrentdate.Thecurrentdateisthen

passedtodateLong,sothatthisexpressionreturnsthecurrentdateformattedasalongdate,e.g.

"February23,2022".

NotethattodayisnotaHelperthatisprovidedbyOLConnect;itisacustomHelper.Tolearnhowto

createthisandothercustomHelpers,see"CreatingcustomHelpers"onpage771.

Subexpressionsaredelimitedbyparentheses.

{{#ifeqab}}.

{{#if(eqab)}}butnowthoseparenthesesareoptional.

Note: Expressionsareevaluatedfromrighttoleft.
