Refer - How to convert a currency string to a double with jQuery or Javascript?[^].

Quote:
Remove all non dot / digits:

JavaScript
var currency = "$1,100.00";
var number = Number(currency.replace(/[^0-9\.]+/g,""));

Yeah, so what is the problem. Just replace the string with element's innerHTML or something, like...

var currency = document.getElementById("someFieldId").innerHTML;

Hi,

Use regular expression.

You may find appropriate example on blogs.

you may use match method.

example:

<HTML>
<BODY>
<script language="javascript" type="text/javascript">
alert("$3000.00onlyd".match(/\d+(\.\d+)/)[0]);
</script>
Done
</BODY>
</HTML>

Thanks
Chetan

Ok I found the solution. Thanks everyone :)

Solution:

string getPrice = "Online Price $15.31";
getPrice = getPrice.Substring(15);

output = 15.31
