How to convert comma separated string into numeric array in javascript

Question

I have a one-dimensional array of integer in JavaScript that I\'d like to add data from comma separated string, Is there a simple way to do this?

e.g : var strVale

Answer 1

This is an easy and quick solution when the string value is proper with the comma(,).

But if the string is with the last character with the comma, Which makes a blank array element, and this is also removed extra spaces around it.

"123,234,345,"

So I suggest using push()

var arr = [], str="123,234,345,"
str.split(",").map(function(item){
    if(item.trim()!=''){arr.push(item.trim())}
})
