Question

I can use JavaScript’s split to put a comma-separated list of items in an array:

var mystring = "a,b,c,d,e";
var myarray = mystring.split(",");

What I have in mind is a little more complicated. I have this dictionary-esque string:

myvalue=0;othervalue=1;anothervalue=0;

How do I split this so that the keys end up in one array and the values end up in another array?

Answer 1

Something like this:

var str = "myvalue=0;othervalue=1;anothervalue=0;"
var keys = [], values = [];

str.replace(/([^=;]+)=([^;]*)/g, function (str, key, value) {
  keys.push(key);
  values.push(value);
});

// keys contains ["myvalue", "othervalue", "anothervalue"]
// values contains ["0", "1", "0"]
