Not to trivialize the opacity of these things, but I used to resist JSON, but actually you can learn it in 10 minutes
http://json.org/ It's actually much easier to grok in some ways than XML and now I prefer it to XML Sure there are deeper, more complex levels, but at a very simple level: This is json fruitColors { "apples":"red", "oranges": "orange", "bananas","yellow" } So LC will return this as an array put fruitColors["apples'] # you will get value "red" For this BMI calculator, that's all JSON you need to know. http://api.clinicalcalculator.org/bmi?height_in_m=1.778&weight_in_kg=68 returns a 2 dimensional array, 2 elements, each of which contains 2 elements {"result": {"value":18.75, "units":"kg/m^2" }, "request_fields": {"height_in_m":"2", "weight_in_kg":"75" } } Graham wrote: "Where did the names ‘result’ and ‘value’ come from?" They came from the first JSON name/value pair Hope that helps BR From: use-livecode <use-livecode-boun...@lists.runrev.com> on behalf of Graham Samuel <livf...@mac.com> Reply-To: How LiveCode <use-livecode@lists.runrev.com> Date: Monday, June 13, 2016 at 12:08 PM To: How LiveCode <use-livecode@lists.runrev.com> Subject: LC8 - Stumbling into JSON Sorry to be a pain, but again in the BMI example for LC 8 there is this function: function getBMI pHeight, pWeight put "http://api.clinicalcalculator.org/bmi?"; & "height_in_m=" & pHeight & "&weight_in_kg=" & pWeight into tURL put url tURL into tJSON put JsonImport(tJSON) into tArray return round(tArray["result"]["value"]) end getBMI Knowing nothing about JSON, I find this confusing to say the least. I see that the JsonImport uses a URL to get some value(s) based on parameters incorporated in the URL, but what am I to make of the ‘return’ statement? I mean what do the bits in square brackets mean? Where did the names ‘result’ and ‘value’ come from? How would one know the spec of the result returned by a particular ‘JsonImport’ invocation? Are there libraries of these things, or what? How much JavaScript will I have to know to use this kind of functionality? Feeling stupid.
