set value to closest input field

[ljubo2015]

Hello, just to let you know this is not issue instead a question :)
I have 1 dropdown and on change event that is triggered if for example value Filter is selected i need to change value of text field to it to some extension name. I am using jquery .on and i am able to do this for one row, but when i extend (add more rows) i am not able to determine input field of that selected row.
Could you please help me with this, thanks in advance.

if your text field keep the same name or id or whatever, your script won't be able to choose the right, seems you need to find method/trick which make correspond the right select with the right field text
