Listen for the Delete Key Using MooTools

By  on  

I saw an interesting ticket hit the MooTools Lighthouse system recently. A user reported that they could not use the following code snippet to listen for the delete key:

var isdel = Event.Keys.delete;

While that generally works, it does not work for the delete key because "delete" is a reserved word. Instead, you must listen for the delete key with this code snippet:

var isdel = Event.Keys['delete'];

Very interesting. As flexible as Moo's language is, you can't get around the reserved words!
