my original data {issues:[{...,"self":"/rest/api/2/issue/175074","key":"grifr14-36",...}, {...,"self":"/rest/api/2/issue/175075","key":"grifr14-37",...}, ...]}. , want reform have array key , value key , self.

so data in jiramapping should [{k1:v1}, {k2,v2}, ...]. when tired print length of jiramapping, length 0. tried put alert check key , value add array , values exist.

i don't know problem exactly. please help...

without knowing information you're passing in, it's hard what's going wrong. being said, first guess data/mydata isn't formatted way think. instance, if mydata.issues.length 0, nothing in loop executed.

there's chance you're never running success function. post more code?
