JavaScript split() function not working

Question

I have a piece of string

"res1"

I want the output to be:

What I have tried till now:

HTML:

<!DOCTYPE html>
<html>
    <body>
        <p id="demo"></p>
        <button type="button" onclick="myFunction()">Try</button>
    </body>
</html>

JavaScript:

function myFunction() {
    var str = "res1";
    var result = str.split("res");
    document.write(result);//returns ,1
    var mystring = result.split(',').join("");

    document.getElementById("demo").innerHTML = mystring;
}

The error which I receive is:

Uncaught TypeError: result.split is not a function

What am I missing?

Could you tell me (which part of the code have i to change???) — Sangamesh Davey

If all you're trying to do is get a number out of a string, you'd be better off with a regex. — ndugger

You can simply do this:

 function myFunction() {
       var str = "res1";
       var result = str.split("res"); // output => ["","1"]
       //document.write(result);//returns ,1
       //var mystring = result.split(',').join("");

       document.getElementById("demo").innerHTML = result[1];
     }

<p id="demo"></p>
<button type="button" onclick="myFunction()">Try</button>

If you generally want to get the last character of the string you could use something like:

var str = "res1";
str.substr(str.length - 1)

The reason yours isn't working is because when you call .split() it returns an array, so when you call result.split(',') you're calling that on an array, which array's do not have this method, which is why you are getting your error. The other answers show an alternative, but I wanted to highlight why you are getting that error.
