86092 - Escaped characters in <a href="javascript:"> blocks the javascript interpreter

Status: RESOLVED DUPLICATE of bug 51355

(Core :: DOM: Core & HTML, defect)

Description

[Emmanuel Bourg]

Mozilla is unable to execute a script called inside an anchor if there is a non
ascii-character escaped in th href property. This might be related to bug 40469.
I'm appending a testcase.

<a href="javascript:confirm('mOziLLa ?');">question 1</a><br>
No non-ascii character in href, the script works as intented and popup a message
dialog.

<a href="javascript:confirm('mÖzïLLà ?');">question 2</a><br>
Non-ascii characters in href, the whole property is escaped into
"<code>javascript:confirm(%27m%D6z%EFLL%E0%20?%27);</code>", the javascript
interpreter reports a syntax error.


Fix suggestion : do not escape href when starting by "javascript:"
