Question

In javascript val is of amount type like $1,056.89. Now i want val to be performed with arithmetic operations but alert gives me as NaN instead of arithmetic value. if i take off Number then y value is as 1,056.8910 .how can i make val to numeric type and perform arithmetic operations?

var val= document.getElementById('<%= DataItemValue4.ClientID%>').firstChild.nodeValue;
            val= val.replace(/^[\s$]+|[\s]+$/g, '');
            y = Number(val)+ 10;
            alert(y);

can any one help me out with this !

thanking you, michaeld

Remove all non numeric characters and coerce the string to a number:

val = + val.replace(/[^\d.-]/g, "");
