XF 2.2 Conditional statement to run java script on multiple selected nodes

[faker.king]

Hello,

I would like to run a java script header on certain nodes only. I currently use below code.

<xf:if is="$containerKey == 'node-55' or $containerKey == 'node-60' or $containerKey == 'node-40' or $containerKey == 'node-47' or $containerKey == 'node-13' ">
    <script       </script>

This code works fine. But wondering how can I reduce the code length by adding the node numbers in an array instead of writing $containerKey variable multiple times

I have tried various ways but none got worked. I think my syntax is wrong.So currently using above code
Any help will be appreciated
