Object.extendsObject - multiple ?

[poyntzj]

I have a custom script include which extends an OOB one - all good

What I now need is to make my script include into an client compatible script, but obviously the Object.extendsObject needs to change to Ajax. Is there a way to extend to multiple objects, so Ajax and the OOB include ?

I had a look at gs.include and that did not work when I did a few initial tests.

For now I will work with an Ajax Include that simply calls the one I really want to call

Hi,

you can have a client callable script include which holds function which can be called from server side.

what is your exact requirement?

Yes that is what I am trying to do and is why I need to change my Script Include. 

It has a number of functions which until now have not needed to be called client side, but a new requirement has meant that I want to call this existing Script include instead of rewriting some code for no reason - and potentially having 2 sets of code to maintain.

My include currently extends an OOB include so I reference mine and call my functions and the OOB functions - it works and to ensure compatibility with existing code, needs to still do this.

For my new requirement I want to make my Script Include client callable, but STILL extend the OOB include

so right now my include has

my_include.prototype = Object.extendsObject(global.OOB_Include, {

When you change to be Client callable, the Object.objectExtends changes to 

my_include.prototype = Object.extendsObject(AbstractAjaxProcessor, {

I want a way that the script can incorporate  BOTH

you cannot just use Object.extendsObject(global.OOB_Include, AbstractAjaxProcessor, {

I did try gs.include and referencing the OOB include but it did not work when I tried it

I would prefer to keep it all in a single Script include which is client callable and still extends an OOB script.

Right now, I am going to write a client callable version that simply calls the Server Side version instead - it works,  but is not as neat and you have to remember any code added to the Server side include needs to be presented in the client callable version too.

Hi @poyntzj ,

I have created this example where you can inherit from multiple classes using Object.extendsObject() function.
