Javascript RegEx Question

How to find below comment block(s) with ja开发者_开发问答vascript/jquery regex:

  /*

    some description here

  */

It may even look like:

  /* some description here
  */

Or

  /* some description here */

With php I think it would be :

$pattern='/\/\*.*?/*///';

or

$pattern='/\*[^*]*\*+([^/*][^*]*\*+)*/';

chk this out

Improving/Fixing a Regex for C style block comments

This is to match empty comment blocks :

^\s+/\*{1,}\n(^\s*\*{1,}\s*)+\*{1,}/

maybe this one could help you

/(\/\*[.\S\s]*?\*\/)/g

seem to be working

Here's an actual Javascript answer:

var commentRegex = /\/\*([^/]|\/[^*])*\*\//;

If you need a version that checks to see whether an entire string is a comment:

var completeCommentRegex = /^\/\*([^/]|\/[^*])*\*\/$/m;

Explanation: the regex matches a leading /*, followed by any number of either individual characters other than "/", or "/" followed by anything not an asterisk, and then finally the closing */. The "m" flag in the second version ensures that embedded newlines won't mess up the "^" and "$" anchors.

Finally, if you actually want the comment text, you'd add an appropriate parenthesized block in there (after the /* and before the */).

var match = myString.match(/\/\*([\w\W]*)\*\//)

If match !== null, match[0] will contain the comment, and match[1] will contain the comment without the comment delimiters.

edit: it's multiline now ;)
