Need Regex for allowing numbers along with

Chaitanya

15y2.9k.NET

Hi all i would like to have a regex that should allow numeric values along with .

also i will have a maximum length for text box as 10 if i enter only numeric it should count if i enter dot it should not count as an input.

Also i wrote a javascript to convert the entered number to US format so my text box will always have its initial value as $.

Example :

If user enters 1234567890 as per my script it will convert as $1234,567,890.00 which works fine but user can enter some thing like 1.23 so that it will convert to $1.23 so i need a regex such that first character should be $ and dot is allowed in between the numbers and only numeric values should count as length

try following javascript code

     function SplChar(evt)
     {
            evt = (evt) ? evt : window.event;
                var charCode = (evt.charCode) ? evt.charCode : ((evt.which) ? evt.which : evt.keyCode);
                if ((charCode >= 48 && charCode <= 57) || charCode == 36 || charCode == 46 || charCode == 44)
                return true;
                else
   return false;

     }
     function btnClick() {
         var objTextBox = document.getElementById("textBox1");
         alert((new RegExp(/^[\$]{1}[\.]?[\,]?\d{1,10}/gi)).test(objTextBox.value));
         if (objTextBox.value.replace(/[\$\.\,]/gi, "").length > 10)
             alert("length exceeded");
     }
