Hi All
I've used jQuery a lot over the years, mostly in the joomla CMS
context. I think I've found a bug in this function:
// Evalulates a script in a global context
globalEval: function( data ) {
The problem is that if there is a newline inside of a string literal
(single quoted) in `data`, then the script fails with an "unterminated
string literal" error. The first thing done to `data` in this
function is this (jQuery 1.2.6):
data = jQuery.trim( data );
But, this trim function only removes leading and trailing whitespace
using a regex, and not with the s modifier to include newlines
matching the \s character class.
jQuery 1.3.2 omits this call to jQuery.trim, and still exhibits the
"unterminated string literal" error when `data` contains a newline
inside of single quotes.
I don't know what the solution should be for sure, but for my own
purposes I've added this line to globalEval before anything is done
with `data`:
data = data.replace(/[\r\n\f]+/g, ' ');
It works on data that contains carriage returns, newlines, or form
feed characters, since these (well, at least the newline) don't work
inside single quotes, when evaluated as a javascript.
Love to hear if anyone else has had this problem.
