Opera: trouble with adding 'list' attribute

Question

Today I've decided to add html5 datalist to certain input via user script. Here's the code. The problem is that list attribute isn't added. If I change it to anything different from list, like lst - it's there.

Is that supposed to be so? Is such behaviour set by specification or by browser?

Answer 1

OK, I did some research on this.

Spec says that input.list returns related datalist object, not the attribute value. So you should use setAttribute('list','edit-subject-themes') on input, which works fine. Seems like it was jQuery issue.

With problem solved, I'll sure use that technique in user JavaScript a lot :)
