You can use .insertBefore()
, like this:
$("#2").insertBefore("#1");
Or, .prependTo()
, like this:
$("#2").prependTo("#parent");
…or the reverse using #1
and .insertAfter()
and .appendTo()
…or several other ways actually, it just depends what you’re actually after, the above 2 methods should be about the shortest possible though, given 2 IDs.
I’m assuming this is just an example, remember to use IDs that don’t start with a number in an actual HTML4 page, they’re invalid and cause several issues.
