Question

I am using javascript regex to add a html markup for all the urls found like:

 var exp = /(((|www\.|(http|https|ftp|news|file)+\:\/\/)[&#95;.a-z0-9-]+\.[a-z0-9\/&#95;:@=.+?,##%&~-]*[^.|\'|\# |!|\(|?|,| |>|<|;|\)]))/ig;

popupText =  popupText.replace(exp , "<font color='red'>"+"<b>$&</b>"+"</font>" ); 

Now the problem is i want to make sure that it will word if the url found length is greater than 20 characters

See $& gets the match string i need to add a filter/check to gets its length.

Any help is appreciated

Answer 1

Use the functional form of replace:

  popupText =  popupText.replace(exp , function(match) {
       if (match.length > 20)
            return "<font color='red'>"+"<b>" + match etc
       else
            return match; // return the argument, that is, don't replace
  })
