Question

I’m collecting text through a web form and noticing that when it is collected by my Perl CGI all instances of “+” are transformed into ” “. I run the text through a JavaScript escape before submission, but escape seems to leave + unaltered.

There must be something really obvious that I’m missing… how do I send the string “2 + 2 = 4” through and not have it arrive as “2 2 = 4”?

The escape and unescape functions do not work properly for non-ASCII characters and have been deprecated. In JavaScript 1.5 and later, use encodeURI, decodeURI, encodeURIComponent, and decodeURIComponent.

Replace escape with encodeURIComponent
