JavaScript encodeURIComponent() Escapes "+" Symbol

Published in Comments (1)

I just blogged about how I was going to have to manually escape the "+" symbol when passing values from my AJAX web page to my ColdFusion back end, but I just happened upon a Javascript method that I have never seen before:


According to, this method was introduced in Javascript 1.5. Here is a small description from the site:

Lastly, the encodeURIComponent() method should be used in most cases when encoding a single component of a URI. This method will encode certain chars that would normally be recognized as special chars for URIs so that many components may be included. Note that this method does not encode the ' character, as it is a valid character within URIs.

This seems to do the trick. Sweet-ass find!

Just used this to pass JSON through the URL. Dumped URL scope on the receiving page and get something looking like this:

{"street_number":32,"viewport":"","administrative_area_level_1":"Auckland","country_short":"NZ","route":"Vialou Ln"}

Wondering how to work with this data, i.e. if there's an easy way to parse the separate variables out into useable format without a lot of list functions and suchlike.

I believe in love. I believe in compassion. I believe in human rights. I believe that we can afford to give more of these gifts to the world around us because it costs us nothing to be decent and kind and understanding. And, I want you to know that when you land on this site, you are accepted for who you are, no matter how you identify, what truths you live, or whatever kind of goofy shit makes you feel alive! Rock on with your bad self!
