How to return part of javascript string that matches regex?

Question

I have a regex string that matches the specific part of the string that I need as seen here .

/[^\/,\s\?#]+?\.[^\/,\s]+?(?=\/|\s|$|\?|#)/g

I want to use this regex in javascript to strip the parts of a string that do not match the regex and then store the result in a variable. I just cant seem to find any way of doing this!

The only regular expression functions I have found in JS are compile(), exec(), test() and toString(). None of these seem to fit my needs. How can I do this?

Thanks

Answer 1

Use string.match function to return all the matched characters as array elements.

string.match(/[^\/,\s\?#]+?\.[^\/,\s]+?(?=\/|\s|$|\?|#)/g)

If you want to remove the matched portion then use string.replace

var s = string.replace(/[^\/,\s\?#]+?\.[^\/,\s]+?(?=\/|\s|$|\?|#)/g, "")

The way to do this would be to use the string.match() function, as seen here on the Mozilla Developer Page .

So, your function call would look like

string.match(/[^\\/,\\s\\?#]+?\\.[^\\/,\\s]+?(?=\\/|\\s|$|\\?|#)/g)

If you plan on stripping away anything that doesn't match, then you could use

string.replace(/[^\\/,\\s\\?#]+?\\.[^\\/,\\s]+?(?=\\/|\\s|$|\\?|#)/g, '') , as seen here and then store it into another variable.
