I have several objects on a page... I know the name of one of the objects and it's stored in a variable called editorId. How can I access that object's methods? editorId.someFunction() doesn't work because the value of the variable is the object's name.

If it's a global variable you could just do var editor = window[editorID];.
If it's local you could do var editor = (new Function('return ' + editorID))();.
Then you could do editor.blah();

This is the best solution, using
window[editorID].someFunction(); should work just fine.If you are referring to an HTML element on the page, you can use:
document.getElementById(editorId);
If you are referring to the name of a JavaScript object, you can try eval(), which is not very efficient:
var obj = eval(editorId);
// obj.someFunction()

use document.getElementsByName(editorId). Alternatively if your name is actually an ID, use getElementById()
