[HtmlUnit] javascript external file not accessible after body tag

From: Mabel C. <mc...@ya...> - 2003-03-13 17:56:36

I read in an archived message that someone else had a problem with
htmlunit not recognizing external javascript files and that message was
dated 9/2002.  I am using version 1.2 (3/10/2003), but I am having the
same problem.

When I reference an external javascript file within the <head> tag and
call a function using onLoad attribute, <body onLoad="someFunc();">, it
CAN recognize someFunc(). However, if I use

<body>
   <script language="Javascript" type="text/javascript">
      someFunc();
   </script>
</body>

I get ScriptException: "someFunc()" is not defined. 
Any ideas why and solutions?  

thanks,
mabel

Looks like you've found a bug in the way I'm loading the javascript. 
This code went through some significant changes for 1.2 in order to 
support document.write().

The external script file isn't getting loaded until the entire html file 
has been parsed but the script tag within the body is executed *during* 
the parsing of the html.  When the inner script is executed, the 
external file hasn't been loaded.

By the time the onload handler is invoked, all the external scripts have 
been loaded so that works properly.

I'll have to write up some tests to prove that it is broken the way I 
suspect.

Does it matter where we insert the external javascript file in the html
code?  If I put it within the body tag, it still doesn't load. For
example:

<body>
    <script language="Javascript" type="text/javascript"
src="myFile.js"></script>
    <script language="Javascript" type="text/javascript">
        someFunc();
    </script>
</body>

Should I open a bug for this?

If I'm right about the problem then no, it won't make a difference where 
the external file is specified.

> Should I open a bug for this?

Yes please.  I'll see if I can get to it this weekend.
