Regex to detect JavaScript

Question

Does someone know how to check if a code begins by <script> and end by </script>. It's just a means to check if code is ok to be inserted in HTML to avoid breaking the site.

So far I've tried to look if <script> is there but I need to check both opening and closing.

Any help would be cool :)

It's the easiest regex to write but it won't check your string is valid. Parse the HTML for that or do additional check. — Denys Séguret

Whoever attempts to answer this question, please take into account that <script>....</script>.....</script> is invalid. — georg

<script[^>]*>([\s\S]*?)<\/script>

Almost correct... except that this doesn't handle double closing tags.

@JMau: You didn’t surround it with /. Also, what is this for?
