Wonder if somebody can help me get some javascript running

I have a url like:

> [https://res.cloudinary.com/XYZ/image/upload/IMG\_5158.jpg](https://res.cloudinary.com/XYZ/image/upload/IMG_5158.jpg)

I need to put in some parameters like:

> [https://res.cloudinary.com/XYZ/image/upload/MYPARAMETERS/IMG\_5158.jpg](https://res.cloudinary.com/XYZ/image/upload/MYPARAMETERS/IMG_5158.jpg)

The filename can be grapped by the javascript as seen in the post below.

But I need to get the first part:

> [https://res.cloudinary.com/XYZ/image/upload/](https://res.cloudinary.com/XYZ/image/upload/)

How can that be done? Or is there a better solution to obtain what I trying to do 🙂

_NB: Seems that all the javascript columns that I create will give the same result even though I change the javascript code. Anyone else seeing the same behavior?_

Try this:

```auto
const bits = p1.split('/');
const last_bit = bits.pop();
return bits.join('/') + `/${p2}/${last_bit}`;

```

@Krivo if you want a way to do this without JavaScript, you could use two Extract Matching Text columns to pull the URL and Filename into two separate columns, and then create a new URL (inserting your parameters) with a template.

Something like this:

Regular Expression for the first column: `^(.*)\/`  
Regular Expression for the second column: `^.*\/(.*)$`
