Hi all,
Opusscript can use prototype to add functions to the array object, because Opusscript is based on ECMAscript which supports prototyping.

I've enclosed an Opus Pro 2.81 pub that contains array functions available in other authoring apps that use vbscript or javascript as their scripting languages.
The functions are Push, Pop, Splice, Shift, Unshift, Max value, Average, Negative value and Shuffle.

As an example the script below adds a max function to the array object.
All arrays on the page will inherit the function.
//-----------------------------------------------------------
function array_max() {
var i, max = this[0];
for (i = 1; i < this.length; i++) {
if (max < this[i])
max = this[i];
}
return max;
}
// set the prototype
Array.prototype.max = array_max;

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

Example of usage::

var ar = new Array(1, 2, 3, 7, 4, 5, 6);

maxval = ar.max() // will return the largest number in the array.

You can add extra functions to the string Object in a similar manner.

Hey Paul - very usefull, Thanx.

Paul,Swan
Downloaded the .imp file.... on preview, I am getting blank page and an output from "Opus Professional Script Console" of the result.

Where is the code?

Using 4.3 Opus....

Paul has used the Debug.trace() function to display the output of each script function in the Script Console.

For example, if you preview the 'Shuffle' page, the script output window will show you the original array and the result of the shuffled array.

If you wish to see the 'code', simply take a look inside the script object on each page of the publication.

Kind regards,

is this file still available?

That's strange -- a lot of the files I've posted over the years seem to have disappeared.
I think this is the file; I haven't checked it as I don't have Opus installed...

cheers
Paul

Thanx, but I still can't see it, I'm logged in, but no link

Edit: Now I've posted that - I can see the link ?!

These functions seem very useful, could you perhaps upload them again? Thanks!

I think this is the file, see attached...

cheers
Paul

It works! Thanks a lot, this can be extremely useful!

Best,
Arnoud
