Passing JSON to custom ColdFusion tag

I am trying to passing in JSON into a custom tag

My tag looks like

<b:column span="{xs=12, md=8}">...

When I get around to processing it I want to use:

 Myspan = DeserializeJSON(attributes.span);

But it just crashes.

enter image description here

I can use

attributes.span     = attributes.span.replacelist('{,=', '{",":');
attributes.span     = attributes.span.replace(', ', ', "', "all");
Myspan              = DeserializeJSON(attributes.span);

But this looks like a hack

Solution

  • {xs=12, md=8} is not JSON, just as the error message indicates.

    You probably want that to be {"xs": 12, "md": 8}

    How are you getting that "JSON" string in the first place? Looks like you might be hand-cranking it - hence it being wrong? If you find yourself hand-crafting JSON strings, you're more than likely going about things wrong, I think. This might be grounds for another S/O question, or perhaps something on codereview..?
