Examples

Script Syntax

Run Example

rainbow = { 
	"Red" : "Whero",
	"Orange" : "Karaka",
	"Yellow" : "Kowhai",
	"Green" : "Kakariki"
};
ui = structReduce( rainbow, ( Any previousValue, Any key, Any value ) => {
	return previousValue & "<dt>#key#</dt><dd>#value#</dd>";
}, "<dl>" ) & "</dl>";
writeDump( rainbow );
writeOutput( ui );

Using Member Function

Run Example

rainbow = { 
	"Red" : "Whero",
	"Orange" : "Karaka",
	"Yellow" : "Kowhai",
	"Green" : "Kakariki"
};
ui = rainbow.reduce( ( Any previousValue, Any key, Any value ) => {
	return previousValue & "<dt>#key#</dt><dd>#value#</dd>";
}, "<dl>" ) & "</dl>";
writeDump( rainbow );
writeOutput( ui );

Additional Examples

Run Example

animals = { 
	COW : {
		NOISE : "moo",
		SIZE : "large"
	},
	PIG : {
		NOISE : "oink",
		SIZE : "medium"
	},
	CAT : {
		NOISE : "meow",
		SIZE : "small"
	}
};
dump( label="All animals", var=animals );
animalInfo = StructReduce( animals, ( Any result, Any key, Any value ) => {
	return arguments.RESULT & "<li>" & arguments.KEY & "<ul><li>Noise: " & arguments.VALUE.NOISE & "</li><li>Size: " & arguments.VALUE.SIZE & "</li></ul></li>";
}, "<ul>" ) & "</ul>";
// Show result
echo( animalInfo );
