Store row ID of repeating sections in hidden attribute

I would like to store the row ID in a hidden attribute such that I am able to  getSectionIDs("repeating_weaponsranged", function(idarray) { for(var i=0; i < idarray.length; i++) { //Do something with the IDs console.log(idarray[i]); setAttrs({ "repeating_weaponsranged_"+idarray[i]+"_weaponsranged_id":idarray[i] }); } }); Is it possible to store the ID in a hidden attribute like this?

Sure, the id is just a string, but what are you trying to accomplish with that?

I want to generate a rollbutton command "!do @{weaponsranged_id} --add-ammunition 1" which tells my API script which rows attribute to modify. Doesn't javascript treat variables for keys in a dict as strings? The above code doesn't set the attribute for this html code: <fieldset class="repeating_weaponsranged"> <input type="text" name="attr_weaponsranged_id" value=""></input> For example: If I understood it correctly in Javascript the following does store the id in an attribute called attr_name and not in the attr_repeating_weaponsranged_X01200129fd87_weaponsranged_id var name = "repeating_weaponsranged_"+idarray[i]+"_weaponsranged_id"; setAttrs({ name:idarray[i] });

If you want to construct the attribute name to set, you need to do it separately from the setAttrs call: var attrs = {}; attrs['repeating_weaponsranged_' + idarray[i] + '_weaponsranged_id'] = idarray[i]; setAttrs(attrs);

Ah thank you!
