ArrayFind

Array finders and contains functions with and without case sensitivity.

Please note that "contain" methods return a boolean, while "find" methods return an index. If you use a function as the value, it will be used as a search closure or lambda. The signature of the function should be:

    ( value, index ) => {
 	  	return true; // if the value is found, else false
   }
 

Example:

   array = [ 1, 2, 3, 4, 5 ];
  index = array.find( ( value, index ) -> {
 		return value == 3;
 } );
 

We recommend you use BoxLang lambdas ({@code ->}) for this purpose, so they only act upon the value and index without any side effects. They will be faster and more efficient.

Method Signature

ArrayFind(array=[array], value=[any], substringMatch=[boolean])

Arguments

Argument	Type	Required	Description	Default
array	array	true	The array to be searched.
value	any	true	The value to find or a closure to be used as a search function.
substringMatch	boolean	false	If true, the search will be a substring match. Default is false. This only works on simple values, not complex ones. For that just use a function filter.	false

Examples

Find an "Apple" in an array of fruit

Returns the index of the element "Apple" in the array

Run Example

writeOutput( arrayFindNoCase( [ 
	"orange",
	"pineapple",
	"apple"
], "Apple" ) );

Result: 3

arrayFind is not Case Sensitive

Not case sensitive so "Apple" will be found in the array, returns 1. Use arrayFind for case sensitive matching.

Run Example

writeOutput( arrayFindNoCase( [ 
	"orange",
	"pineapple",
	"apple"
], "Apple" ) );

Result: 1

Member Functions: Find an "Apple" in an array of fruit

Calls the findNoCase member function of the array object.

Run Example

fruit = [ 
	"orange",
	"pineapple",
	"apple"
];
writeOutput( fruit.findNoCase( "Apple" ) );

Result: 3

Additional Examples

Run Example

arrVariable = [ 
	"Water",
	"Sky",
	2,
	"Air"
];
WriteDump( ArrayFindNoCase( arrVariable, 5 ) ); // Outputs 0
WriteDump( ArrayFindNoCase( arrVariable, "air" ) ); // Outputs 4
WriteDump( ArrayFindNoCase( arrVariable, 2 ) );
 // Outputs 3
