i have a search engine in .js that writes a report. the report
has a button to a scripted function if searched value needs adding
have stripped engine code to only part that writes report.
if i comment out the included script display works but not
when it is in the .js file .... this stuff works ok in msie
and opera but not in mozilla based stuff. the .js file is
// verified with jslint 2003:05:17
var docObj = document; var queryvalue = "freddy"; //global defaults
// search function would have more -- stripped to rudiments
function asearch() {
var winvar = docObj.open("","fred"); // capture window handle
if (winvar !== undefined) {docObj = winvar;} // but not when Opera ;-{
docObj.writeln('<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">');
docObj.writeln('<html><head><title>TEST 3<\/title>');
docObj.writeln('<link href="zestyle.css" rel="stylesheet" type="text/css">');
docObj.writeln('<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">');
// comment out next four lines to make it work in mozilla
docObj.writeln('<script type="text/javascript">\nfunction mailit() {');
docObj.write('top.location.href="mailto:ve3ll@rac.ca');
docObj.writeln('?Subject=EducationSite! needs ['+queryvalue+'] in db!";');
docObj.writeln('} <\/script>');
docObj.writeln('<\/head><body>');
docObj.writeln('<h1>Hello buddy<\/h1>');
docObj.writeln('<\/body><\/html>');
docObj.close();
}
AND A SIMPLE DRIVER FUNCTION IS :
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html><head><title>Driver</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript" src="asearch.js"></script>
</head><body><h1>test</h1>
<form name="f" action="?" method="post">
<input name="x" type="button" value="go!" onClick="asearch();">
</form></body></html>
Reproducible: Always
Steps to Reproduce:
1.Add the two scripts to local drive as asearch.js and test.htm
2.run test in opera or msie to see expeced results
3.run test and press button --- notice no head written
4.comment appropriate lines in .js and rerun to observe
that expected results now happen
Actual Results:
no head displayed in report
also cant view anything with frame -- view source
Expected Results:
displayed the head and allowed view source.

If we strip down the example to a minimum, and place all the JS
in-line, we have
<html><head>
<script>
var docObj = document;
var queryvalue = "freddy";
function asearch()
{
var winvar = docObj.open(); // capture window handle
alert(queryvalue);
docObj.close();
}
</script></head>
<body><br>
<input type="button" value="Test" onclick="asearch();">
</body></html>
When we run this testcase in IE6, we get the alert ---> "freddy".
In Mozilla, we get the same error in the JavaScript Console as
in the example you gave above:
Error: queryvalue is not defined
The reason is, you are doing a document.open() after the global
variable |queryvalue| is defined. In Mozilla (but not IE) that
destroys the JS context and replaces it with a brand-new one.
In the new JS context, the variable |queryvalue| has not been
defined, hence the error in the JavaScript Console.
This is not a JS Engine issue, so I'm reassigning this to the
DOM experts. This bug is either invalid or a duplicate of
bug 114461, "document.open() clobbers JS context"

Summary: when reading .js files that write scripts to new file -- display hangs → display hangs
