SRC =并且缺少.JS文件 [英] SRC= and missing .JS file
问题描述
无法在网上的常见问题解答中找不到答案...
关于许多javaScript的提示''他们说的网站会警告用户
关于丢失的.JS文件应该执行以下操作：
< html>
< ; head>
....
< script src =" ABC.js" ...>
alert（错误！包含的JS文件未找到...）;
< / script>
< / head>
....
但它在我的IE 6和我的Mozilla 1.6中都不起作用 -
当.JS文件不存在时没有警报。

说，
"当使用SRC属性时，嵌入的脚本将被忽略。
，当没有找到.JS时，它不会触及案例
（或者是吗？忽略了_always_？）
那么如何告诉用户没有找到要包含的.JS？

（或者是吗？忽略了_always_？）
那么如何告诉用户没有找到要包含的.JS？
我一直在试验以下内容，似乎有效。在
..js文件中，将以下语句放在顶部。
var script111loaded =" true";
现在在HTML中放入
< script type =" text / javascript">
if（！script111loaded）{alert（" script 111 not loaded"） };
< / script>

我在IE中测试过它。我应该跟随Netscape。
为什么不像if（document.getElementById）{xxx}这样的测试在某些浏览器中给出一个
未定义的错误，或者是吗？

Hi,
Could not find the answer neither in FAQs not on the Web...
On many javaScript ''tips'' sites they say that do warn the user
regarding missing .JS file one should do the following:
<html>
<head>
....
<script src="ABC.js" ...>
alert("Error! Included JS file not found ...");
</script>
</head>
....
But it does NOT work neither in my IE 6 nor in my Mozilla 1.6 -
no alert when the .JS file does not exist.
http://www.htmlhelp.com/reference/ht...al/script.html
says,
"When the SRC attribute is used, the embedded script is ignored."
which does not touch the case when .JS not found
(or does it? Ignored _always_?)
So how to tell the user that .JS to be included was not found?

I''ve been experimenting with the following and it seems to work. In the
..js file put the following statement at the top.
var script111loaded = "true";
Now in the HTML put
<script type="text/javascript">
if (!script111loaded) {alert("script 111 not loaded")};
</script>

Thanks, it works (though, I had to declare that variable
at the top of my _html_ text,too - otherwise _if_ did not
work - just has "undefined" error in JS Console, at least
in Mozilla 1.6).

I tested it in IE. I should have followed through with Netscape.
Why doesn''t a test like "if (document.getElementById) {xxx}" give an
undefined error in some browsers, or does it?
