Subject [jira] [Commented] (FREEMARKER-16) js_string buit-in function escapes '/' for first character
Date Mon, 14 Mar 2016 13:42:33 GMT

    [ https://issues.apache.org/jira/browse/FREEMARKER-16?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15193298#comment-15193298
] 

Martin Těthal commented on FREEMARKER-16:
-----------------------------------------

We have been used this built-in (?js_string) for escaping both " and ' for JSTL tag attributes.
Specifically where single-quotas are required (simplified <f:MyTag value='${val?js_string}'
/>). Escapation of "/" character is not expected here. I understand that ?js_string is
used for JavaScript escaping so the documentation of jsStringEnc method in your reply is much
more complex to do this job. We expected the behaviour of http://freemarker.org/docs/ref_builtins_string.html
documentation. We'll rewrite it to ${val?j_string?replace("'", "\'")}, but if you'll plan
to add some other built-in to do this simple job (ie. escape single & double quotas and
characters under 0x20) it will be welcomed.

> ${"bar/foo"?js_string} returns "bar/foo"
> but
> ${"/foo"?js_string} returns "\/foo" (the first slash character is escaped by backslash).
> I think the problem is from version 2.3.1 as documentation says:
> Starting from FreeMarker 2.3.1, it also escapes > as \> (to avoid </script>).
