I would like to replace all the characters other than 0-9 in a string, using Javascript.

Why would this regex not work ?

 a100.dfwe.replace(/([^0-9])+/i, )

You need the /g modifier to replace every occurrence:

a100.dfwe.replace(/[^0-9]+/g, );

I also removed the redundant i modifier and the unused capturing sub-expression braces for you. As others have pointed out, you can also use D to shorten it even further:

a100.dfwe.replace(/D+/g, );
