I am trying to understand what selectObjId is. I have seen a few examples online but what it actually does, I am not very clear on. Could anyone please explain what it does, which language it belongs to AJAX? If possible could i please have an example that prints out the value referenced by selectObjId. Any form of help will be appreciated.

selectObjId is anything you want it to be if you define to that naming a function, object, value...

e.g in Javascript (ECMAScript):

var selectObjId = document.getElementById('funnydiv');

P.S ObjID = JAVA

JDK Doc(JAVA)
- class java.rmi.server..ObjID public final class ObjID extends Object implements Serializable Tree:java.lang.Object - java.rmi.server.ObjID An ObjID is used to identify remote objects uniquely in a VM over time. Each identifier contains an object number and an address space identifier that is unique with respect to a specific host. An object identifier is assigned to a remote object when it is exported. If the property java.rmi.server.randomIDs is true, then the object number component (64 bits) of an ObjID created with the no argument constructor will contain a cryptographically strong random number. - Constructor for class java.rmi.server.ObjID public ObjID () Generates a unique object identifier. If the property java.rmi.server.randomIDs is true, then the object number component (64 bits) of an ObjID created with the no argument constructor will contain a cryptographically strong random number.Since: JDK1.1 - Constructor for class java.rmi.server.ObjID public ObjID (int num) Generates a "well-known" object ID. An object ID generated via this constructor will not clash with any object IDs generated via the default constructor.Parameters: num - a unique well-known object numberSince: JDK1.1

I don't think selectObjId is anything special in any library out there. It is probably just a mistake that it was never declared in the code you are using.

Javascript is very forgiving. It is quite possible that selectObjId has not been declared, but that your code still works. Depending on how you use it, it could also be the name of a function.

You can test by using console.log(selectObjId) to see what it prints out. You may need to have Firebug installed. Have a look at the Firebug help get more info on errors and warnings.
