You need to add the  global  flag to your regex   s replace new RegExp   0-9     g     X     or  perhaps prettier  using the built-in literal regexp syntax    replace   0-9  g   X

The  g modifier is used to perform a global match  find all matches rather than stopping after the first   You can use  d for digit  as it is shorter than  0-9    JavaScript   var s    04 07 2012    echo s replace   d g   X       Output   XX XX XXXX

You forgot to add the global operator  Use this    x000D   x000D  var s    04 07 2012   x000D  alert s replace new RegExp   0-9    g     X      x000D   x000D   x000D

Use  s replace   d g   X     which will replace all occurrences  The g means global match and thus will not stop matching after the first occurrence   Or to stay with your RegExp constructor   s replace new RegExp    d    g     X
