Matching regex href=javascript

Question

I have regex that matches href='javascript:...' or href="javascript:..." , but I also want to match a href=javascript:... without quotes.

How can I do it?

My regex: /\\bhref\\s*=[^"']*(?:"([^"]*)"|'([^']*)')/gi

Strings that I want to match:

<a href='javascript:alert(1)' sometags>click me</a>
<a href="javascript:alert(1)" sometags>click me</a>
<a href=javascript:alert(1) sometags>click me</a>

Sample of code:

while((match = reg.exec(s)) !== null) {
    // In each cases I want to get javascript:alert(1) in match
}

Answer 1

Add another case to your alternative. If there's no quote, it matches until the next whitespace or > .

/\bhref\s*=\s*(?:"([^"]*)"|'([^']*)'|([^\s>]*))/gi
