Copy of ticket #3051, cant believe this was closed!

This wasted a good few hous of my time, surely a string check could be done here to avoid this causing problems for other people in the future.

I would rather see an error thrown rather than a jq object containing multiple results, this is really dangerous behaviour especially if your chaining and inadvertinly set many attributes instead of the one desired.

From 1.2.6 source:

443 eq: function( i ) {

444 return this.slice( i, i + 1 );

445 }

This works fine when passed an integer. Selects a range when passed a string. For example:

.eq("1")

passes ("1", "11") to slice instead of (1, 2).
