" " is not defined - Javascript

Evan Sussman

Could any one give me an explenation of this error? I get it every
once in a while, and it really is a pain. currently the code that I'm
working with goes like this

<script>

</script>

that goes in the <HEAD>
and then it is called multiple times from the body like this

<div align="center"> <font face="Verdana, Arial, Helvetica,
sans-serif" size="1"><font color="#993333" ><strong>Sundan ce
/ Cabin</strong><br>
<a onClick="checkw indow()"
target="moviewi ndow"
href="javascrip t:moviepopup('m ovies/05-01.mov');"><img
src="images/movies/05-01.gif" alt="" name="" width="100" height="100"
border="0"></a></font> </font><br>
<font color="#993333" size="1"
face="Verdana, Arial, Helvetica, sans-serif">Click to Play</font><br>
<font face="Verdana, Arial, Helvetica,
sans-serif" size="1"><font face="Verdana, Arial, Helvetica, sans-serif"
size="1"><font color="#993333" > </font></font></font></div>

Now, if you can't tell what the effect I'm going for, its like this.
When you click on a picture, a sized windows appears with a movie
inside it. it loads and plays. If/When another movie is clicked on the
original page, I want the second movie to reload in the "moviewindo w" I
was advised to write checkwindow() by a javascrpt guru through the
email, but it is hard to keep a conversation with him. can anyone help
me with this. thanks

Please do not show us unnecessary code, it distracts.
<a onClick="checkw indow()"
target="moviewi ndow"
This target declaration is never used by your javascript, skip it.
href="javascrip t:moviepopup('m ovies/05-01.mov');">

The onclick needs a return:

onClick="return checkwindow()"

but I would prefer not to use the href="javascrip t:.. at all, try:

<a onClick="if (checkwindow()) moviepopup('mov ies/05-01.mov');"
href='#'>

Or still better, move the moviepopup() into the checkwindow() function

<img src="images/movies/05-01.gif" alt="" name="" width="100" height="100"
border="0"></a></font> </font><br>

skip most of this showing it to us.

thanks, will try.

ok, when I changed

<a onClick="checkw indow()" target="moviewi ndow"
href="javascrip t:moviepopup('m ovies/05-01.mov');">
to
<a onClick="if (checkwindow()) moviepopup('mov ies/05-01.mov');" >href="javascri pt:moviepopup(' movies/05-01.mov');">
It worked, but it still returned "moviewindo w is not defined" on line
31

then I tried it with
href="#"

and it wouldn't load, still returned "movie is not defined" on line 31

so somehow, the href to the javascript is still needing to play a part
in the script. anyone have any suggestions. thanks Evertjan, as your
last post was very helpful.

when I remove the href altogether, it still gives the same error as the
href="#" I guess that was a stupid attempt.

It worked, but it still returned "moviewindo w is not defined" on line
31

And it isn't!

You assign window.open's result to newwindow and have newwindow as a
global variable. You should therefore use:
if (!newwindow.clo sed && newwindow.locat ion) {
moviepopup(url) ;
}

There is probably another way to get to the moviewindow object (as you
assigned it that name), but not the way you're doing it.

Cheers,
Andy

now, after trying what you said Andy, it reloads the original window,
and gives the error "newwindow has no propertys" at line 31

Is the page available online anywhere?

Anyway, try changing it to:

if (newwindow && !newwindow.clos ed && newwindow.locat ion) {
moviepopup(url) ;
}

This should check to see if newwindow is set.

Cheers,
Andy

after changing that, all it does is reload this time no errors. I guess
we're making progress, well now we can't target an error. Now we gotta
get the window to open, and the original window not to reload.

Is "scope" different from "visibility" ?

by: TTroy | last post by:

I have a few questions about "scope" and "visibility," which seem like two different things. To me "visibility" of the name of a function or object is the actual code that can use it in an actual program. To me "scope" of the name of a function or object are the general rules for the areas of a program that can through a declaration, have "visibility."

typeof operator returns "unknown" instead of "undefined"

IE7 returns "unknown" instead of "undefined" when querying the type of an unknown property of an object, for example document.write(typeof window.missingproperty); Has "unknown" been defined as a valid return value for the typeof operator in a later version of ECMAScript or is this a JScript "feature"? -- Klaus Johannes Rusch
