Safe arrays

Back to JavaScript samples

Some adsi methods return a safe array. Use it by method:

var vbArray = new VBArray(adsiObj.GetEx("cn"))

var values = vbArray.toArray()

So, some adsi methods need a safe array. There is a function of a conversation from javascript array to safe array.

function SafeArray()

{

var dic = new ActiveXObject("Scripting.Dictionary");

var a = arguments;

if (1 == a.length && 'object' == typeof a[0] && Array == a[0].constructor)

a = a[0];

for (var i = 0; i < a.length; i++)

dic.Add(i, a);

return dic.Items()

}

Example of an using:

var userObj = GetObject("LDAP://" + someDN);

userObj.GetInfoEx(SafeArray("department", "title"), 0);

var title = userObj.Get("title");

Advanced

This is a library code extends VBArray object.

// ----------------------------------------------------------------------------

// VBArray

// ----------------------------------------------------------------------------

(function()

{

var dic = new ActiveXObject("Scripting.Dictionary");

//

// Returns safe array from JavaScript array

//

// Example of an using,

// var safeArray1 = VBArray.parse(["A", "B", "C"]) // returns an array has 3 items

// var safeArray2 = VBArray.parse("A", "B", "C") // returns an array has 3 items

VBArray.parse = function()

{

var a = arguments;

if (1 == a.length && "object" == typeof a[0] && Array == a[0].constructor)

a = a[0];

for (var i = 0; i < a.length; i++)

dic.Add(i, a);

var values = dic.Items();

dic.RemoveAll();

return values

}

//

// Returns JavaScript array from safe array.

//

// Example of an using,

// var array1 = VBArray.toArray(safeArray)

VBArray.toArray = function()

{

if (0 == arguments.length || null == arguments[0])

return null

var temp = new VBArray(arguments[0])

return temp.toArray()

}

//

// Returns a length of a VBArray instance

//

// Example of an using,

// var count = VBArray.parse(["A", "B", "C"]).count() // it equals: ["A", "B", "C"].length

VBArray.prototype.count = function()

{

return (1 + this.ubound() - this.lbound())

}

}

Using example:

WScript.Echo("Conversation using");

var safeArray = VBArray.parse("A", "B", "C")

var vbArray = new VBArray(safeArray)

WScript.Echo(" VBArray");

for (var i = 0; i < vbArray.count(); i++)

WScript.Echo(" " + i + ": " + vbArray.getItem(i));

// direct get js array

WScript.Echo(" JS Array");

var jsArray = VBArray.toArray(safeArray);

for (var i = 0; i < jsArray.length; i++)

WScript.Echo(" " + i + ": " + jsArray);

WScript.Echo("Samples of conversation");

var vb = (new ActiveXObject("Scripting.Dictionary")).Items();

WScript.Echo("[0] " + vb.count());

WScript.Echo("[1] " + VBArray.parse(["A"]).count());

WScript.Echo("[2] " + VBArray.parse("A").count());

WScript.Echo("[3] " + VBArray.parse(["A", "B", "C"]).count());

WScript.Echo("[4] " + VBArray.parse("A", "B", "C").count());

WScript.Echo("[5] " + VBArray.parse([new ActiveXObject("Scripting.Dictionary")]).count());

WScript.Echo(" " + VBArray.parse(new ActiveXObject("Scripting.Dictionary")).count());
