Is it Possible to use JQuery in Thingworx Services?
In my services, if I try to do:
Assumption for this post:
#id is valid.
$("#id").show(); <-- I get the error ReferenceError: "$" is not defined.
Alternatively, if I do:
document.getElementById("id").style.display = "block"; <-- I get the error ReferenceError: "document" is not defined.
