Loading fro

I'm kindof a newbie to Jquery. I'm trying to load the codes using JQuery UI Autocomplete. I'm able to load it if I hard code the values in the script. I'm trying to do the same from the txt file. I have it in my C folder in my local system. I'm kind of stuckup with how to handle the file path

I have it in this way currently "file:///C:\Users/vthummalapallyDocuments\proc_codes.txt".

Any help on this is appreciated.
