Extract Number from String

Copy linkTweet thisAlerts:
Jan 15.2009

Hi All,

How would I go about extracting a number from a string value. I have a form in which users can enter monitary values. I have no idea what they will enter so I want to extract the number including decimal from whatever they enter. For example if the user enters $134,876.00 I want to extract 134876.00.

I am trying to use a regular expression to accomlish this but can’t seem to get it to return a single number. It returns an array if the number is broken up in the middle.

[code]var x = 123adv456.8;
var r = x.match(/[0-9.]+/g);[/code]

Thanks in advance for any help.

@paulnicJan 15.2009 — why dont you add some form validation instead which forces the user to enter just numbers?

</i>var x = '123adv456.8';
var r = x.replace(/[^0-9\.]/g, '').replace(/^(d*.d*)..*$/, "$1") * 1.0;
