Is it possible to access an embedded data field in Javascript when dynamically constructing its field name?
For example, let's say the field I want is `result.elements.0.embeddedData.V1`, but I only know the last character should be `1` at runtime (the number is drawn from a loop & merge index).
I want to do something like:
var n = "${lm://CurrentLoopNumber}"; // ex. n = 1
var ed = eval("${e://Field/result.elements.0.embeddedData.V"+n.toString()+"}");
But this doesn't work, `ed` just comes up `null`.
(Sanity check: `console.log("${e://Field/result.elements.0.embeddedData.V1}");` does produce the value I'm expecting.)
I imagine this is because of the order of operations somehow (either that or `eval()` can't execute `$` syntax?) It seems like by the time my string concatenation occurs, there isn't a good way to access the embedded data with the concatenated name.
Any ideas?
Note: I found
this answer which sets embedded data fields with the target index as a second L/M field.
E.g.
LM Field 1 = 2
LM Field 2 = ${e://Field/myfield_2}
That's close to what I want, but because my starting index is variable and is set by a query string, I need to do something more like
with start_ix = 1:
LM Field 1 = $e{e://Field/start_ix + 1}
LM Field 2 = $e{e://Field/myfield + $e{e://Field/start_ix + 1}}
But that doesn't work - nor do I expect it to, as I don't think embedded data "math" supports string concatenation in the same way the `+` operator can concat strings in Javascript.
