" "没有定义 [英] " " is not defined
问题描述
任何人都可以告诉我这个错误吗？我偶尔会得到每一个
，这真的很痛苦。目前我和我一起工作的代码是这样的
< script>
<！ -
var newwindow;
function moviepopup（url）
{
newwindow = window.open （url，''moviewindow''，''height = 28 0，width = 340，toolbar = no，menubar = no，locatio = no，statu s = yes，left = 435，top = 25''）;
if（window.focus）{newwindow.focus（）}
}
function checkwindow（）
{
if（！moviewindow.closed&& moviewindow.location）{
moviepopup（url）;
}
else
{
返回false;
}
}
- >
< / script>
进入< HEAD>
然后从这个身体多次调用它
< div align =" center">< font face =" Verdana，Arial，Helvetica，
sans-serif" size =" 1">< font color ="＃993333">< strong> Sundance
/ Cabin< / strong>< br>
< a onClick =" checkwindow（）"
target =" moviewindow"
href =" javascript ：moviepopup（ ''movies / 05-01.mov''）;">< img
src =" images / movies / 05-01.gif" ALT =""名称= QUOT;"宽度= QUOT; 100" height =" 100"
border =" 0">< / a>< / font> < / font>< br>
< font color ="＃993333" size =" 1"

< ; 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>
现在，如果你不知道我想要的效果是什么，就像这样。
当你点击一张图片时，会出现一个大小的窗户，里面有一部电影
。它加载和播放。如果/当在
原始页面上点击另一部电影时，我希望第二部电影在moviewindow中重新加载。我建议你通过
电子邮件给javascrpt大师写一个checkwindow（），但很难和他保持对话。任何人都可以用这个来帮助我。谢谢

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>
<!--
var newwindow;
function moviepopup(url)
{
newwindow=window.open(url,''moviewindow'',''height=28 0,width=340,toolbar=no,menubar=no,locatio=no,statu s=yes,left=435,top=25'');
if (window.focus) {newwindow.focus()}
}
function checkwindow()
{
if (!moviewindow.closed && moviewindow.location) {
moviepopup(url);
}
else
{
return false;
}
}
-->
</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>Sundance
/ Cabin</strong><br>
<a onClick="checkwindow()"
target="moviewindow"
href="javascript:moviepopup(''movies/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 "moviewindow" 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

don''自2000年以来再使用它
var newwindow;
function moviepopup（url）
newwindow = window.open（url，''moviewindow ''，''height = 28 0，width = 340，toolbar = n
o，menubar = no，locatio = no，status = yes，left = 435，top = 25''）;
if（window.focus）{newwindow.focus（）}
有时新窗口在应用焦点时还没准备好。
为什么窗口没有重点，你刚刚点击它？
我想代码应该是[并测试]：
if（ newwindow）{newwindow.focus（）}
}
函数checkwindow（）
如果（！moviewindow.closed& ;& moviewindow.location）{
moviepopup（url）;
这里补充：
返回true
}
其他
其他不一定非必要
{
返回false;
}
}

如上所述
< / script>
进入< HEAD>
然后它从身体多次被称为

请不要向我们展示不必要的代码，它会分散注意力。
< a onClick =" checkwindow（）"
target =" ; moviewindow"
此目标声明永远不会被您的javascript使用，跳过它。
href =" javascript ：moviepopup（''电影/ 05-01.mov ''）;">
onclick需要退货：
onClick =" return checkwindow（）"
但我宁愿不使用href =" javascript ：..试试：
< a onClick =" if（checkwindow（））moviepopup（''movies / 05-01.mov''）;"
href =''＃''>
或者更好，将moviepopup（）移动到checkwindow（）函数中
< img src =" images / movies / 05-01.gif" ALT =""名称= QUOT;"宽度= QUOT; 100" height =" 100"
border =" 0">< / a>< / font> < / font>< br>
< font color ="＃993333" size =" 1"
face =" Verdana，Arial，Helvetica，sans-serif">点击播放< / 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>
跳过大部分内容向我们展示。
从这里开始

<script>
missing type=''text/javascript''
<!--
don''t use this anymore since 2000
var newwindow;
function moviepopup(url)
{
newwindow=window.open(url,''moviewindow'',''height=28 0,width=340,toolbar=n
o,menubar=no,locatio=no,status=yes,left=435,top=25 '');
if (window.focus) {newwindow.focus()}
perhaps sometimes the newwindow is not ready when applying the focus.
why should window not have the focus, as you just clicked in it?
I suppose the code should be [and be testing for that]:
if (newwindow) {newwindow.focus()}
}
function checkwindow()
{
if (!moviewindow.closed && moviewindow.location) {
moviepopup(url);
Here add:
return true
}
else
else not realy necessary
{
return false;
}
}
-->
as above
</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>Sundance
/ Cabin</strong><br>
Please do not show us unnecessary code, it distracts.
<a onClick="checkwindow()"
target="moviewindow"
This target declaration is never used by your javascript, skip it.
href="javascript:moviepopup(''movies/05-01.mov'');">
The onclick needs a return:
onClick="return checkwindow()"
but I would prefer not to use the href="javascript:.. at all, try:
<a onClick="if (checkwindow())moviepopup(''movies/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>
<font color="#993333" size="1"

<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>
skip most of this showing it to us.

谢谢，会尝试。
thanks, will try.
好的，当我改变
ok, when I changed
< a onClick =" checkwindow（）" target =" moviewindow"
href =" javascript ：moviepopup（''movies / 05-01.mov''）;">
to
< a onClick =" if（checkwindow（））moviepopup（''movies / 05-01.mov''）;" ; > HREF ="的JavaScript的 的：moviepopup（电影/ 05-01.mov）;">
它有效，但仍然返回moviewindow未定义在线
然后我尝试了用
href ="＃"
<a onClick="checkwindow()" target="moviewindow"
href="javascript:moviepopup(''movies/05-01.mov'');">
to
<a onClick="if (checkwindow())moviepopup(''movies/05-01.mov'');" >href="javascript:moviepopup(''movies/05-01.mov'');">
It worked, but it still returned "moviewindow is not defined" on line
31
then I tried it with
href="#"
并且它不会加载，仍然返回电影未定义在第31行
所以不知何故，javascript的jref仍然需要在脚本中扮演一个部分
。任何人都有任何建议。谢谢Evertjan，你的
最后的帖子非常有帮助。
-Evan
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.
