You can escape quotes inside strings using backslashes:

alert('L\'appareil est en panne\'');

there's a Java class that seems to do the job: StringEscapeUtils.escapeJavaScript(). Boy, you Java guys have a class for everything!

Altough your question is not very clear. But you can use escape character \' to resolve such problems.
