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(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?

Since array literal notation is still valid JSON, you can use JSON.parse() to convert that string into an array, and from there, use it's values.

var test = "[1,2]"; parsedTest = JSON.parse(test); //an array [1,2]  //access like and array console.log(parsedTest[0]); //1 console.log(parsedTest[1]); //2
