Question

I have written a c# code to read string values within brackets “()”

 string s = "Hello (World) This is (Working)";
            int i = 0;
            while ((i = s.IndexOf('(', i)) != -1)
            {
                int stop = s.Substring(i+1).IndexOf(')');
                string output = s.Substring(i + 1, stop);
                Console.WriteLine(output);

                i++;
            }

            Console.ReadLine();

with this code I get

World Working

I want to implement this in JavaScript So I tried this

function myFunction()
{
var s = "Hello (World) This is (Working)";
            var i = 0;
            while ((i = s.indexOf('(', i)) != -1)
            {
                var stop = s.substring(i+1).indexOf(')');
                var output = s.substring(i+1, stop);
                document.write(output);
                i++;
            }
}

but It has different output

ss (

I am not good at javaScript, Please help me find a solution in this method I dont want to use regex

Despite similar names, these aren’t actually using equivalent methods (note the 2nd arguments):

• C# — Substring(int index, int length)
• JS — substring(int indexA, int indexB)

Try substr instead for the JavaScript — substr(int index, int length):

function myFunction()
{
    var s = "Hello (World) This is (Working)";
    var i = 0;
    while ((i = s.indexOf('(', i)) != -1)
    {
        var stop = s.substr(i+1).indexOf(')');
        var output = s.substr(i+1, stop);
        document.write(output);
        i++;
    }
}
