Convert a JavaScript String to an array

Question

I have a Spring Controller which passes a Set of Strings to the view but as a single String:

"[AB, NK, LK]"

However, I need to convert the above String into an equivalent JavaScript array like the following:

["AB", "NK", "LK"]

I have tried the following jQuery to iterate through the String "[AB, NK, LK]" in order to add these values to a <select> tag:

$.each(arrayCodes, function(index, value) {
        $("#select").append("<option value='" + value + "'>" + arrayCodeValues[index]
                + "</option>");
});

Why not have the controller give you valid JSON? So you could JSON.parse? — gen_Eric

@RocketHazmat Yep, thought of that. However, I am passing a number of values (different values) to the view. In my case, it would actually be a lot more work. Of course, I would have shown my Java controller code, but it is out of the question's scope. — blackpanther

I agree with @RocketHazmat this sounds somewhat like an XY problem. — Colin DeClue

You can do

var arr = "[AB, NK, LK]".slice(1,-1).split(", ")

With a regular expression

var vals = "[AB, NK, LK]".match(/[A-Z]{2}/g);

Check the use of split function here if you want http://www.w3schools.com/jsref/jsref_split.asp this could solve your problem.

var sText = "[AB, NK, LK]";
var arrayCodes= str.split(",");

$.each(arrayCodes, function(index, value) {
        $("#select").append("<option value='" + value + "'>" + arrayCodeValues[index]
                + "</option>");
});
