ArrayUtil - Global
The ArrayUtil script include provides methods for working with JavaScript arrays.
These methods are available to any server-side script.
ArrayUtil - concat(Array parent, Array child)
Merge two arrays.
| Name | Type | Description |
|---|---|---|
| parent | Array | An array to merge |
| child | Array | An array to merge |
| Type | Description |
|---|---|
| Array | An array of elements from both input arrays. Duplicates are not removed. |
var arrayUtil = new ArrayUtil();
var a1 = new Array("a", "b", "c");
var a2 = new Array("c", "d", "e");
gs.print("concat a1, a2: " + arrayUtil.concat(a1, a2));
Output: concat a1, a2: a,b,c,c,d,e
ArrayUtil - contains(Array array, Object element)
Searches the array for the specified element. Returns true if the element exists in the array, otherwise returns false.
| Name | Type | Description |
|---|---|---|
| array | Array | Array to search. |
| element | Object | Element to search for. |
| Type | Description |
|---|---|
| Boolean | Flag indicating whether the element was found in the array. Possible
values:
|
var arrayUtil = new ArrayUtil();
var a1 = new Array("a", "b", "c");
gs.print("Contains b: " + arrayUtil.contains(a1, "b"));
gs.print("Contains x: " + arrayUtil.contains(a1, "x"));
Contains b: true
Contains x: falseArrayUtil - convertArray(Object a)
Converts a Java object to an array.
| Name | Type | Description |
|---|---|---|
| a | Object | Object to convert. |
| Type | Description |
|---|---|
| Array | Array created from the object. |
This example converts a Java object to an array.
var arrayUtil = new ArrayUtil();
// Returns a JavaObject with the logged in user's groups
var groupObj = gs.getUser().getMyGroups();
gs.print('groupObj: ' + Object.prototype.toString.call(groupObj));
var groupArr = arrayUtil.convertArray(groupObj);
gs.print('groupArr: ' + Object.prototype.toString.call(groupArr));
Output:
groupObj: [object JavaObject]
groupArr: [object Array]
ArrayUtil - diff(Array a, Array b)
Finds the differences between two or more arrays.
Any number of arrays can be provided as parameters.
| Name | Type | Description |
|---|---|---|
| a | Array | An array |
| b | Array | An array |
| Type | Description |
|---|---|
| Array | Returns an array of items from array a that were not found in either array b or c, or other input arrays. Duplicates are removed from the result. |
var arrayUtil = new ArrayUtil();
var a1 = new Array("a", "b", "c");
var a2 = new Array("c", "d", "e");
gs.print(arrayUtil.diff(a1, a2));
Output: a,b
ArrayUtil - ensureArray(Object object)
Returns an array from the specified object.
| Name | Type | Description |
|---|---|---|
| object | Object | Object from which to create an array. |
| Type | Description |
|---|---|
| Array | Array created from the object. |
The following example shows how to create an array from an object and display created array.
var arrayUtil = new ArrayUtil();
var o1 = {a:"1",b:"2",c:"3"};
gs.print('o1 is array: ' + Array.isArray(o1));
gs.print('o1 stringified: ' + JSON.stringify(o1));
var a1 = arrayUtil.ensureArray(o1);
gs.print('a1 is array: ' + Array.isArray(a1));
gs.print('a1 stringified: ' + JSON.stringify(a1));
o1 is array: false
o1 stringified: {"a":"1","b":"2","c":"3"}
a1 is array: true
a1 stringified: [{"a":"1","b":"2","c":"3"}]The following example shows how to create an array from an object and display the contents of the array.
var stock = { 'name': 'Servicenow', 'sym': 'NOW' };
var arr = new ArrayUtil();
var stArray = arr.ensureArray(stock);
gs.info("Name is " + stArray[0]['name']);
gs.info("Symbol is " + stArray[0]['sym']);
Name is Servicenow
Symbol is NOWArrayUtil - indexOf(Array array, Object element)
Searches the array for the element. Returns the element index or -1 if not found.
| Name | Type | Description |
|---|---|---|
| array | Array | Array to search. |
| element | Object | Element to search for. |
| Type | Description |
|---|---|
| Number | Position of the element in the array, or -1 if the element is not found. |
var arrayUtil = new ArrayUtil();
var arr = new Array("a", "b", "c", "x", "y", "z");
gs.print("Array: " + arr);
gs.print("Index of a: " + arrayUtil.indexOf(arr, "a"));
gs.print("Index of a starting at 2: " + arrayUtil.indexOf(arr, "a", 2));
gs.print("Index of c: " + arrayUtil.indexOf(arr, "c"));
gs.print("Index of c starting at 1: " + arrayUtil.indexOf(arr, "c", 1));
gs.print("Index of z: " + arrayUtil.indexOf(arr, "z"));
gs.print("Index of z starting at 4: " + arrayUtil.indexOf(arr, "z", 4));
// If negative value is sent as startIndex then (startIndex + length of array ) is considered as start index.
// startIndex = -1+(6); startIndex is considered as 5 in this case
gs.print("Index of c starting at -1 (Re-Calculated to 5): " + arrayUtil.indexOf(arr, "c", -1));
// startIndex = -10+(6) which is -4,if negative value again then startIndex is considered as 0
gs.print("Index of c starting at -10 (Re-Calculated to 0): " + arrayUtil.indexOf(arr, "c", -10));
