Getting the current component's name

Category: Server Side JavaScript
Platform: All
Release: 8.5.2
Role: Developer

Replies: 2

Now, you might remember the good old @ThisValue and @ThisName in the Notes client. @ThisName was useful, because you could use it to generate another field name for calculation purposes, or whatever. The point is, @ThisName was an easy way to get a handle on the current field's name.

I'm sure there must be a similar ability within XPages. Where in SSJS you can refer to the current component, but for the life of me, I can't see it. I've checked the documentation read the XPages manual, etc etc, but haven't been able to come up with anything.

Anyone able to help me out with this?

Cheers

Re: Getting the current component's name

Hi,

Have you tried the "this" object?

A check to what "this" refers to (e.g. in a SSJS event) you could print the type to the server console:

print( "this is " + typeof this);

If "this" refers to the current event, you can use this.getParent() to retrieve the event's parent (e.g. a button control).

To get code completion when refering to this, you have to assign it to a local variable and specify its clas:

var t:<object-class-here> = this;

then you enter t. and get a list of all properties/ methods

Re: Getting the current component's name

Hi Mark - thanks for your help. And on a Sunday, too :)

Following your advice, I found that when using a computed text field, the type is com.ibm.xsp.component.xp.XspOutputText

Checking the type hierarchy, this is a subclass of javax.faces.component.UIComponent

so a general solution to this problem is :

var v:javax.faces.component.UIComponent = this;

v.getId();

Which does the trick nicely.

Mind you, I do miss the old @ThisValue (just kidding :)

Cheers
