Function SpecialCharsMapOrStruct

encoding/ghtml/ghtml.go:75–138

SpecialCharsMapOrStruct automatically encodes string values/attributes for map/struct. Note that, if operation on struct, the given parameter `mapOrStruct` should be type of pointer to struct. For example: var m = map{} var s = struct{}{} OK: SpecialCharsMapOrStruct(m) OK: SpecialCharsMapOrStruct(

(mapOrStruct any)

// OK: SpecialCharsMapOrStruct(&s)
// Error: SpecialCharsMapOrStruct(s)
