i have a string

var traingIds = ${triningIdArray};  // ${triningIdArray} this value getting from server 

alert(traingIds)  // alerts [1,2]

var type = typeof(traingIds ) 

alert(type)   // // alerts String

now i want to convert this to array so that i can iterate

i tried

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

$.each(trainindIdArray, function(index, value) { 

    alert(index + ': ' + value);   // alerts 0:[1 ,  and  1:2]

});

how to resolve this?

Assuming, as seems to be the case, ${triningIdArray} is a server-side placeholder that is replaced with JS array-literal syntax, just lose the quotes. So:

var traingIds = ${triningIdArray};

not

var traingIds = ${triningIdArray};
