I have a regular expression that currently matches any non-numeric characters:

var.replace(/[^0-9a-zA-Z ]/,'');

I now need to keep the spaces as well as numbers, but I am having difficulty modifying this.

Any help?

• Your regex does not match "any non-numeric characters"; it doesn't match alphabetic characters. – Pointy Commented Feb 13, 2013 at 16:04
• your regex matches none alpha-numeric characters .. not only numeric characters – Hussein Nazzal Commented Feb 13, 2013 at 16:06
• @Rohit Jain - I have been trying things, that is why the regex is almost plete, but I apologise for not being the JavaScript guru you expect me to be. – Jon Commented Feb 13, 2013 at 16:07

[^0-9\s]

explanation hey regex engine :

1- match every thing .

2- ^ --> that's not

3- 0-9 --> a number

4- \s --> and a space
