JavaScript regex replace - but only part of matched string?

Question
I have the following replace function
myString.replace(/\s\w(?=\s)/,"$1\xA0");
The aim is to take single-letter words (e.g. prepositions) and add a non-breaking space after them, instead of standard space.
However the above $1 variable doesn't work for me. It inserts text "$1 " instead of a part of original matched string + nbsp.
What is the reason for the observed behaviour? Is there any other way to achieve it?
Solution
$1 doesn't work because you don't have any capturing subgroups.
The regular expression should be something like /\b(\w+)\s+/
.
OTHER TIPS
Seems you want to do something like this:
myString.replace(/\s(\w)\s/,"$1\xA0");
but that way you will loose the whitespace before your single-letter word. So you probably want to also include the first \s
in the capturing group.
