Use Javascript variable in object name?

Question

I am using CKEditor, and referring to the CKEditor instance, I need to use a variable. But, since calling an instance is an object, I'm really not sure how to do this.

I use:

CKEDITOR.instances.textarea123.insertHtml('<p>Whatever</p>'); 

The problem is that I need the variable 123, because I need to change the instance based on the loaded editor page.

So how can I use a variable in the name of an object?

For obvious reasons, the following does not work, but I need to get it to "pretend":

 var id = 354; CKEDITOR.instances.textarea+id+.insertHtml('<p>Whatever</p>'); 

Answer 1

Try the following:

 var id = 354; CKEDITOR.instances['textarea'+id].insertHtml('<p>Whatever</p>'); 

Answer 2

You can use array notation:

 CKEDITOR.instances['textarea' + id].insertHtml('<p>Whatever</p>'); 

Answer 3

 var id = 354; CKEDITOR.instances["textarea" + id].insertHtml('<p>Whatever</p>'); 

Since instances are an object, and objects are essentially hash tables, you can access them using an array notation.
