onclick Client-side Code problem

[pagates]

Hello All--

I'm having a problem getting an onclick event to work. Here is my setup: I
have an external JavaScript file, a master page that registers the javascript
as an external file, and a content page that has controls that I am trying to
get onclick to work for.

// =====================
// MyScriptFile.js
// =====================
function ReportOnClick(msg)
{
alert('ReportOnClick: ' + msg);
}

// =====================
// MasterPage.master.cs
// =====================
protected void Page_Load(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptInclude("MyJavaSc riptFile",
"MyScriptFile.js");
}

// =====================
// ContentPage.aspx.cs
// =====================
protected void Page_Load(object sender, EventArgs e)
{
if (! IsPostback)
{
// Does not work
Label1.Attributes.Add("onclick", "ReportOnClick('Label1 was
clicked.');");

// Does not work
// Label1.Attributes.Add("onclick",
"javascript:ReportOnClick('Label1 was clicked.');");

// Does work
// Label1.Attributes.Add("onclick", "alert('Label1 was clicked.');");
}
}

So, the adding of the attribute works fine, as I get an alert if I hardcode
one in. However, whenever I try to access a function in my external script,
I get a "Microsoft JScript runtime error: Object expected".

Any ideas?

Thanks,

There was a similar problem discussed in another thread recently...

How are you including the JavaScript file in the MasterPage...?

Hmm - yes, I think I see the problem...

Can you please do a View Source on the page and show the markup which the
above code has generated i.e. the "<include..." line in the header...

You're using the wrong format for the include. This format doesn't include a
file, but includes the code instead. The version you want takes three
parameters, not two. Check out the sample at:

The following is in the body (not the header):
<script src="MyScriptFile.js" type="text/javascript"></script>

Note: there are other functions in that file that are called correctly, but
they are during the window.onload and window.onresize events, which are coded
into the javascript file. It seems to be a problem specifically with onclick.

[pagates]

Hi Mark,

Using either call for the function results in the same code in the body:

<script src="MyScript.js" type="text/javascript"></script>

The following is in the body (not the header):
<script src="MyScriptFile.js" type="text/javascript"></script>

Indulge me...

1) Temporarily comment out the server-side code which adds the include file

2) Hard-code the above markup into the MasterPage, but with one tiny
modification:

<script src="MyScriptFile.js" type="text/javascript "></script>

Note the extra space at the end of "text/javascript "

Does it work now...?

No, but....

Hard-coding the markup (without the space) seems to allow it to work
correctly.

Or should that be spelled "correctly?!" So, it looks like there is a
problem somewhere in the mechanism with the RegisterClientSideInclude
function when specifying a javascript event with the same name as a
server-side event.

I'm not sure why I didn't think of trying that myself earlier, but I
didn't... Thank you!

Thanks again,

Damn! Scroll down to the thread entitled "menu controls on 2.0",
specifically the last few posts - I was hoping this might be the same
thing...

Hmm - there's "definitely" something not quite right with include files in
MasterPages...

I'm not sure why I didn't think of trying that myself earlier, but I

Welcome!

[pagates]

Wow. Damn is right! : )

I've done the Submit a Bug thing through the VS feedback. We'll see what
happens.

Thanks again for the help.

Wait a minute. I stand (un)corrected. I am still having the same problem
with the hard-coded page (although, by God, it did work once, for some
"random" reason).

There's clearly something wrong here - e,g, MasterPages won't even process a
self-closing <script /tag - has to be <script></script>

[pagates]

Well, at least it's "nice" to have confirmation from somebody else that it's
not just me...
