Select then print multiple nodes

[iPFT]

Hi all - is there anyway to have a list of parent nodes selected one at a time and printed out/saved?

Basically I have a requirement to be able to select a set of parent ids that are all at say level 3, then output the hierarchy for each parent and can't find an easy way to do this in js. I can do some things in the console, but when it comes to looping, or repeating the console script automatically am struggling.

e.g. ids: 1,2,5,7

The user clicks a button and the first parent node is selected and then outputs a jpg (or png or pdf), then moves on to the next parent node and repeats through the array.

Thanks
