Question

I’m trying to create objects from a key/value list. My Problem is, that Object Properties have to be valid JavaScript identifiers. At least with Adobe ExtendScript I can perfectly create an Object with a wrong Property (See Example: wrong-key -> “-“-Literal is invalid).

var kvp = ["key;value", "wrong-key;value"];
var obj = {};

for (var i = 0 ; i < kvp.length; i++) {
    pair = kvp[i].split(";");
    obj[pair[0]] = pair[1]; 
}
alert (obj.key);
alert (obj.wrong-key); // -> Throws an Error

Of course I could run a replace(/-/,"_"), but is there any encoding/escaping function out there to accomplish this goal more generally?

thanks,
gregor

Answer 1

you can access those properties with special chars using the array notation

console.log(obj["wrong-key"]);
