check this out :)

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

//remove square brackets
traingIds = traingIds.replace('[','');
traingIds = traingIds.replace(']','');
alert(traingIds);  // alerts 1,2        
var trainindIdArray = traingIds.split(',');

​for(i = 0; i< trainindIdArray.length; i++){
    alert(trainindIdArray[i]); //outputs individual numbers in array
    }​
