How to make array with string list

Question

I have a generated list which is like this

196-1526, 85-651, 197-1519

I need the array like this. Each node has two part. I need only the first part of each node in one array.

196, 85, 197

I already have this code which generage 196

str.substr(0,str.indexOf('-'));

Answer 1

You could use the following:

'196-1526, 85-651, 197-1519'.replace(/-\d+(,|$)/g, '').split(/\s/)

Answer 2

If the input is a string you can use split() and push(), similar to this:

var x = "196-1526, 85-651, 197-1519"
var y = x.split(',');

var myArray = [];

for(i = 0; i < y.length; i++){
    myArray.push(y[i].split('-')[0].trim());
}
