Adding JavaScript Validation on ASP.NET Textbox

[JJ_377]

I want a JavaScript validation function to fire on an ASP.NET textbox's
change event.

Here's what I've been trying and it is not working. The following added
in the webform's page load event:

txtBirthdate.At tributes.Add("t xtBirthdate_Tex tChanged",
"MyJSFunction() ")

txtBirthdate.At tributes.Add("T extChanged", "MyJSFunction() ")

txtBirthdate.At tributes.Add("o nchange", "MyJSFunction() ")

txtBirthdate.At tributes.Add("o nChange", "MyJSFunction() ")

I've been usual a simliar construct sucessfully with .net hyperlinks:

hlSSN.Attribute s.Add("onclick" ,
"openMessageWin dow('../Information.htm ')")

Thank you very much.

I suggest you customize one of the validation controls.
This article shows you how:

Also...

I am wondering if you can recommend a resource or an approach to
validating international telephone and address info.

I note that while .NET features validators for distinct entities --
such as a French phone number OR a German phone number -- there is no
control for validating a phone number which in theory could be entered
by a user from any country. I note that the .net validators are
designed for European countries, and of them, only very few are
represented...

I had thought about creating a custom validator that would run through
the countries I could define, but is this really the best way to do
things when in theory, each country could feature a very distinct phone
number format. The same question concerns me regarding postal codes.

?

Thank you again for any and all.

It definitely sounds like some custom code would be needed to fit your
somewhat unique requirements.

Yes. I am surprised that it is unique. I suspect/hope things will look
quite different 10 year from now.
