How do I remove numbers from a string using Javascript?
I am not very good with regex at all but I think I can use with replace to achieve the above?
It would actually be great if there was something JQuery offered already to do this?
//Something Like this??
var string = 'All23';
string.replace('REGEX', '');
I appreciate any help on this.
\d matches any number, so you want to replace them with an empty string:
string.replace(/\d+/g, '')
I've used the + modifier here so that it will match all adjacent numbers in one go, and hence require less replacing. The g at the end is a flag which means "global" and it means that it will replace ALL matches it finds, not just the first one.
"str 12.3 or 12,3".replace(/\d+([,.]\d+)?/g)
"-1000".match(/\d+/g); will return "1000" not "-1000".
"str 12.3 or 12,3".replace(/\d+([,.]\d+)?/g, '')Just paste this into your address bar to try it out:
javascript:alert('abc123def456ghi'.replace(/\d+/g,''))
\d indicates a character in the range 0-9, and the + indicates one or more; so \d+ matches one or more digits. The g is necessary to indicate global matching, as opposed to quitting after the first match (the default behavior).
g flag otherwise it fails on "abc123def456"
