Hi ,

I have a TextBox. I want to add only decimal and integer values only in that.
for that i wrote code like this

C#

function ValidateText(i) {
           if (i.value.length > 0) {
               i.value = i.value.replace(/[^\d]+/g, '');
           }
       }

But when i enter the Decimal value it's not taken the "." value. can any one help me to resolve this issue.
