Tizen Studio false positive "problems"

I have two javascript files as part of my project in Tizen Studio 2.3, lets say A.js and B.js.  I've defined some functions in B.js that are used by functions in A.js...of couse, my index.html references both A.js and B.js as script sources.  Yet, Tizen Studio says I've got an undefined function in A.js (even though it IS defined in B.js) How do I tell Tizen Studio to look broader across the whole project rather than just the current script for defined functions?

Hi,

Could you please attach the log.

Alan Buch

By "log" I think you mean the contents of the "Problems" tab.  Here it is below... In this post, I added line numbers for reference.  I have several .js files; weather.js, BHD08.js, utility.js, etc.  I've bolded a great example of the "false positive" which can be seen at lines 4 and 5 below... I've defined a function called "getTemperature" in the weather.js file.  I use the getTemperature function in my BHD08.js.  This code works fine.  Yet, Tizen Studio 2.3 thinks that there's an issue... On line 4 it says that I've defined the getTemperature function in weather.js but that it is "never used".  But not true.  I do use it in BHD08.js.  Not surprisingly, it also thinks that my use in BHD08.js of that same function (that it said I didn't use!) "is not defined".

Hi,

Check out how you added B.js in A.js(referencing B.js within A.js).
Add only A.js and call a function that extends
to B.js. Make a simple test function, nothing
complicated. Then see what error/log emerge.
Then add two js and observe log.

it sounds like" jslint" warning problem.

put the follwoing line on top of the B.js (lets assume that "Bfunc" and "BObject" are what you want to share with A.js)

/* exported Bfunc, BObject */

Then put the following line on top of the A.js

/* global Bfunc, BObject */

After that it will not generate the warning anymore.

but be careful not to make runtime "undefined" error.
