问题
Sometimes when I copy javascript from jsfiddle into Dreamweaver I end up banging my head in the wall. Two documents with (what looks to be) the EXACT same javascript doesn't work in the same way.
In document A I have the following code:
<script>
alert('test')
</script>
In document B I have the following code (does not work):
<script>
alert('test')
</script>
Note: Please copy code B in to a html document and try if it alert before giving me comments. I am not joking, there is something weird going on.
I have located the problem to be something with the end script tag, but I can't see any thing wrong with the code.
Whats the difference in the code from document A and B?
回答1:
You've got an Zero-width space (U+8203) behind the closing bracket.
The bug is known to jsfiddle, it seems to be an issue with the codemirror syntax highlighter.

When copy and pasting the javascript code from jsfiddle (using Chrome browser) into Dreamweaver I get a invisable Unicode charactar at the end of the script.
This little one: "" (yes there is a character between those...)
This mess up the javascript and it is hard to locate the problem.
If you have a similar problem as mine you can search for the character by copying it from the "" above.

Try:
<script type="text/javascript">
alert("Test");
</script>

Where do you put this code in the page ?
Try using <script type="text/javascript"> instead of just <script>.
In order to work, you script need to be anywhere between <head></head> or <body></body>.
Have you try another browser ? Are you sure Javascript is enabled ?
