Javascript/Jquery Convert string to array

Question

i have a string

var traingIds = \"${triningIdArray}\";  // ${triningIdArray} this value getting from server 
alert(traingIds)  // alerts [1,2]
var type = typeof         


        

Answer 1

Change

var trainindIdArray = traingIds.split(',');

to

var trainindIdArray = traingIds.replace("[","").replace("]","").split(',');

That will basically remove [ and ] and then split the string
