How to escape '$' and '#' in Facelets/EL?

Question

I\'m using Java Facelets and jQuery, however the expression

$(\'...\')

in jQuery conflicts with EL expression, how do I escape the jQuery\'

Answer 1

Should anyone need to, the Expression Language Specification Version 2.2 Maintenance Release describes how to escape EL expressions:

To generate literal values that include the character sequence "${" or "#{", the developer can choose to use a composite expression as shown here:

${'${'}exprA}
#{'#{'}exprB}

The resulting values would then be the strings ${exprA} and #{exprB}.

Alternatively, the escape characters \$ and \# can be used to escape what would otherwise be treated as an eval-expression. Given the literal-expressions:

\${exprA}
\#{exprB}

Answer 2

This should normally not conflict. EL uses ${} syntax. Anyway, you could either use jQuery() instead (the $() is just a shorthand) or simply put JS code in its own .js file.
