​Hi,

What javascript version is included in isam 9.0.6.0
It says in the lmi that it uses ES 6.
I wish to use this.

['a', 'b', 'c'].includes('b')

But gets:
Caused by: org.mozilla.javascript.EcmaError: TypeError: Cannot find function includes in object a,b,c. (InfoMap#4)


------------------------------
Regards Mikael

Hi Mikael,

java.util.ArrayList Java class is available to use in writing  JavaScript rules in ISAM, the above logics could be written in following with java.util.ArrayList class

var array = new java.util.ArrayList();
array.add("a");
array.add("b");
array.add("c");
var isIncluded = array.contains("b");

Best Regards

Hi Mikael,

The 9.0.6 appliance has Rhino 1.7.9 onboard, which claims to have all features of JavaScript 1.7. And JavaScript 1.7 claims to be conform with EcmaScript edition 6. Yes, it's complicated :-).
It seems like Rhino does not have all the 'fancy' features, see this link for an overview of the compatibility: 
http://mozilla.github.io/rhino/compat/engines.html
And then look for ".includes" -> it seems Rhino can only use .includes() on string objects. While the EcmaScript standard says it should work on just any object...
For reference only: here's the link to EcmaScript ed 6: http://www.ecma-international.org/ecma-262/6.0/index.html

Kind regards, Peter.

Hi Peter

Would you know what Rhino version is bunlded with ISAM 9.0.7.0 and 9.0.7.1 ?

We're looking to use the Map() object but it get's rejected at runtime as not supported.

Hi Sylvain,

I was wondering too, so I did some digging around, but it's not completely clear: it seems v9.0.7.1 ships with both Rhino v1.7.9 and v8.0.0:
[isam@3b9bc0a04f73 usr]$ pwd; find . -name *rhino*.jar
/opt/ibm/wlp/usr
find: './servers/default/certs': Permission denied
./servers/runtime/workarea/org.eclipse.osgi/190/0/.cp/rhino-1.7.9.jar
./extension/lib/isam/rhino/com.ibm.security.access.thirdparty.rhino_8.0.0.jar
[isam@3b9bc0a04f73 usr]$

Judging on the paths, I assume v1.7.9 is the "standard" one, but there may be some way to activate v8.0.0 through an extension?
Not sure if v8 would help you though, as the rhino project states:

"Rhino 1.6 and greater implement ECMA-357 ECMAScript for XML (E4X). See the specification for more information on the standard, and Rhino version 1.6R1 release notes for details on the implementation in Rhino."

Rhino does allow to use java objects, so if you really need the map, you could try to leverage the java map object (but you'll need to take care of the subtile differences between js strings and java strings): https://developer.mozilla.org/en-US/docs/Mozilla/Projects/Rhino/Embedding_tutorial#Expose_Java_APIs

Hi,

I had a quick look on the ISAM 9.0.7.1 VM I have running on my laptop. The Rhino version is 1.7.9.
I'm almost sure that the rhino_8.0.0.jar file that @Kristof Goossens mentioned has no meaning when it comes to the Rhino version that is used by ISAM. Also the latest Rhino is 1.7.12 as seen on this link
To verify the Rhino version that's used by an ISAM appliance, I downloaded an ISAM support file​, unzipped that file, and looked at the ls.txt file in the iswga directory. I saw lots of packages with an 8.0.0 postfix, so I'm assuming it's more like an ISAM-internal way of packaging things. 

Cheers, Peter

Hi Mikael,

Whenever you wish to use functions that are not supported, I recommend looking for them at MDN.
Usually, there is a "polyfill" for it there. A Polyfill is a function definition that extends the prototype. All you need to do is paste it in your script and you'll be able to use it as if you where working in a JS engine that supports it.

For the includes example, you can find the polyfill code here: https://developer.mozilla.org/nl/docs/Web/JavaScript/Reference/Global_Objects/Array/includes#Polyfill

On this topic , one way I generally use to verify which functions are available in javascript objects in ISAM mapping rule is to 

get the Object.getOwnPropertyNames for that object and trace it :

IDMappingExtUtils.traceString("print functions for Array.prototype : " + Object.getOwnPropertyNames(Array.prototype));


 in this case in 9060 It says :


... functions for Array.prototype : constructor,toString,toLocaleString,toSource,join,reverse,sort,push,pop,shift,unshift,splice,concat,slice,indexOf,lastIndexOf,every,filter,forEach,map,some,find,findIndex,reduce,reduceRight,,length
