Question About .NET Controls and Javascript

[Jonathan Wood]

I have a TextBox on a Web form that I'll be accessing from code. However,
I'd also like execute some Javascript when the control loses focus.

I'm a little confused since the IDE does not seem to present javascript
events when a control has the runat="server" specified. I know I can type it
in but that wouldn't that be specifying my server-side handler rather than
client script?

I'm pretty sure I need this to be a server-side control but would like to
connect some client-side script. Is this even possible?

Thanks.

You 'll have to add a Attributes.Add( "onclick", "javascript:fun ction")
on the server side to associate a client event handler to a server
control. {Just check on the syntax coz I've not worked on Web apps 4
sometime.}

Hope it helps.

Yes. This should get you going - "Using JavaScript Along with ASP.NET 2.0"

Re: Question About .NET Controls and Javascript

Any attribute that is not recognized on server side will just be emitted to
the client as it is. So

<asp:Text ... abc="xyz" /will produce

<input type="text" abx="xyz" />

RE: Question About .NET Controls and Javascript

For lost focus you would do:

myTextBox.Attri butes.Add("onbl ur", "javascript:myf unction")

Re: Question About .NET Controls and Javascript

That article looks like just the thing I needed.

However, there's one area that I didn't see it address: How to reference
controls by name. Because if I have a TextBox with ID="txtLbs" it actually
ends up with a name something like
"ctl00_ctl00_Co ntentPlaceHolde r1_MainContent_ Wizard1_txtLbs" . I need to
reference two controls from the javascript. I had to hard code these names
because they could potentially change. Anyone have any ideas?

Thanks.

Re: Question About .NET Controls and Javascript

My concern was that it might match one of the ASP.NET control's server-side
events/attributes. But perhaps most of those have different names.

Re: Question About .NET Controls and Javascript

Heh, I looked at a table of javascript events had didn't relate to onblur
being when a control lost focus. That name only makes sense in an odd sort
of way. Cool.

I also found a good article based on another suggestion. But do you have any
ideas how I would reference other controls from javascript, given that the
IDs of ASP.NET controls can change substantially by the time the HTML is
rendered?

Thanks!

Re: Question About .NET Controls and Javascript

Looks like I got this working. I used the ClientID property to obtain the
final control ID.

Thanks!
