• javascript

• 2 You can use split(w3schools./jsref/jsref_split.asp) for this – Apb Commented Mar 28, 2016 at 6:42
• 2 OP, no-one's said explicitly but str.split() produces an array. You can access the elements using the indexes as shown in the answers. – Andy Commented Mar 28, 2016 at 6:46

Try this:

    var id = "100-200";
    var arr = id.split("-");
    alert(arr[0]);
    alert(arr[1]);

With simple JavaScript:

ID = "100-200";
var values = ID.split('-');

var id_part1 = values[0];
var id_part2 = values[1];

var id = "100-200";
var array = id.split("-");
var id_part1 = array[0];
var id_part2 = array[1];

Use Split: Try this

var str = "100-200";
var res = str.split("-");

Result is in array list.

You can use :

var ID= "100-200" ;
ID=ID.split('-')[1];
var id_part1 = ID[0];
var id_part2 = ID[1];

Now it can be done in one line with the destructuring assignment:

var ID = "100-200";
var [id_part1, id_part2] = ID.split('-');

console.log('id_part1: ', id_part1);
console.log('id_part2: ', id_part2);
