- Example for the JSONToVariant function
Example for the JSONToVariant function When using JSON with a fixed content, you can declare only once the WLanguage structures that are filled by a JSON deserialization with Deserialize. However, when using a JSON file whose content can change, it must be read in order to retrieve all its members and values. When the JSON file is read, it is converted to a variant. This code shows how to perform a "generic" iteration over the variant loaded from JSON content. sJSon is ANSI string = [
{
"Member1": "Value Member 1",
"Member2": "Value Member 2",
"Member3": "Value Member 3",
"Member 4": {
"Member 5": {
"Member 6": 6,
"Member 7": "Value Member 7"
},
"Member 8": {
"Member 9": 9,
"Member 10": "Value Member 10"
}
}
}
]
let vjs = JSONToVariant(sJSon)
FOR EACH _Member OF vjs..Member
IF _Member..Member..Count = 0 THEN
Trace("The member " + _Member..Name + " has the value " + _Member..Value)
ELSE
Trace("The member " + _Member..Name + " has " + _Member..Member..Count + ...
" other members")
BrowseVariantMembers(_Member)
END
END
INTERNAL PROCEDURE BrowseVariantMembers(x)
FOR EACH _Member OF x..Member
IF _Member..Member..Count = 0 THEN
Trace(Repeat("--", StringCount(dbgInfo(dbgStack), CR)) + ...
"The member " + _Member..Name + " has the value " + _Member..Value)
ELSE
Trace(Repeat("--", StringCount(dbgInfo(dbgStack), CR)) + ...
"The member " + _Member..Name + " has " + _Member..Member..Count + ...
" other members...")
BrowseVariantMembers(_Member)
