In my case, I am having multiple comma in between the numbers as well.

const str = ",1,8487,8,,848780,888,,";
const parsedStr = str.match(/\d+/g)
document.write(parsedStr)

Even easier

var result = test.slice(1,-1);

Below code sample will do this

        var str = ",1,2,3,4,5,6,7,8,9,";
        str = str.substring(1,str.lastIndexOf(","));

test.substring(1, test.length - 1); should do it for you.

Regex should help

var edited = test.replace(/^,|,$/g,'');

^, matches the comma at the start of the string and ,$ matches the comma at the end ..
