Hi All

i found two javaScript seperatly

1. CreditCard Number
function Mod10(ccNumb)
Refference: https://www.azcode.com/mod10/mod10.js

2. Routing number
function ABAMod10(aba)

hi
there is one sugggestion make a one function and call both function in new function and onchange funtion call this new created function.
and in this new function place the condition that
if this credit card i mean first funtion return true then called second otherwise you can know this is not credit card by executing first function in this case you should not need to executing second function.

Hi,
There are many ways to solve your problem.

1. onchange event call single method and call second method inside onchange event function.
<form id="form1" runat="server">
    <asp:TextBox ID="TextBox1" runat="server" onchange="return DoValidate(this);">asp:TextBox>
    form>
Call DoValidate function here inside this function I called another fuction as you can see below code.
2. You can do it by putting the two functions in double quotes:
<input type="text" value={this.state.text} onChange="this.props.onChange(); this.handleChange();" />
Jquery:
function testFunction() {
    onChange();
    handleChange();
}
Thanks, I think this is very helpfull for you.
