[xwiki-users] how to escape quote in velocity for javascript ?

Hello everybody, I've a simple problem. I've a text input where people can enter some text. After, I want to send that text as a param to a javascript function. However, when user types a quote (simple or double), there is a problem in my javascript syntax. I've tred to add backslash but no effect. Thanks for your help. Mathieu Canzerini.
