How do I select inputs having a name like "abc[]" with Prototypejs ?

Question

I want to select an input with Prototypejs and its $$ function.

I am able to do this :

$$('input')

But I want to be more accurate in my search, with a name of an input. The name of the input I want to select is "array[]" :

$$('input[name="array[]"]')

I think the [ and ] in the name are creating troubles because the result I get are the same as if I did this :

$$('input')

How do i select the inputs having a name such as "something[]" ?

Answer 1

You can be a little more verbose and use :

$$('input').findAll(function (o) { return o.name=="array[]"; })

Answer 2

Are you probably looking for

$$('input[name="array[]"]')[0]

because $$() returns an array of input elements? Works for me.

Answer 3

It seems like it was a bug with prototype 1.6.0.3 and probably lower versions.

Works with prototype >= 1.6.1
