Remove all non alphanumeric and any white spaces in string using javascript

Question

I'm trying to remove any non alphanumeric characters ANY white spaces from a string.

Currently I have a two step solution and would like to make it in to one.

var name_parsed = name.replace(/[^0-9a-zA-Z ]/g, ''); // Bacon, Juice | 234
name_parsed = name_parsed.replace(/ /g,'')
console.log(name_parsed); //BaconJuice234

Could someone let me know how to achieve above in one execution and not two?

You include a whitespace in the original regular expression! — epascarello

@VisioN - true, there's the underscore, but as long as the string doesn't contain an underscore it's not an issue. Was just a suggestion really ! — adeneo

Remove the space from the first set and will do the job:

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

You may read this code as "remove all characters that are not digits ([0-9]) and alpha characters ([a-zA-Z])".

Alternatively, you can use the i flag to make your regular expression ignore case. Then the code can be simplified:

name.replace(/[^0-9a-z]/gi, '');

@VisioN this doesn't work for me in the following example: "sdf234 234dfsf".replace(/[^0-9a-zA-Z]/g, '') I just did this in Firebug console, not sure why it wouldn't work. Result = "sdf234234dfsf"

@Jacques What exactly doesn't work? To your result it works as expected: it removed all characters apart from digits and Latin letters.
