I have a script over here: JsFiddle
If you scroll down in the javascript at some point you will see function urlencode (str) { So from this on till the bottom is a piece of code I don’t understand. I have never seen such coding and I also dont know why this is in the script. It seems that deleting this is not an option since the script will not work without. So I actually have two questions:
1.Why is this in the script?
2.How do I get rid of it to shorten my code?
1. The script is there to encode special characters as Hex so they can be safely transmitted as plain text without being corrupted en-route
2. Don’t get rid of it. If you want to shorten it, take all the comments out 🙂 You could also whizz it through a minifier…
You could look online for shorter JavaScript URLEncode routines, or see if you are already using an existing library which provides such functionality. However I would stick with the one you’ve got as it may do something specific to your application.
