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?
This question is related to
javascript
jquery
Change
var trainindIdArray = traingIds.split(',');
to
var trainindIdArray = traingIds.replace("[","").replace("]","").split(',');
That will basically remove [
and ]
and then split the string
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
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
}?
