Need JavaScript bug help
In the following code, I am trying to get the value of the Select box. It works in Mozilla, but not IE. Any help would be apprecated. -t- \n{form name="mainform" method="post" action="somewhere.htm" target="_blank">\n\t{input type="submit" name="removebut" value="Press Me" \n\t\tstyle="width:200" onClick="buttonsClick('removebut')">\n\t{p>\n\t{select name="filterset">\n\t\t{option>foo\n\t\t{option>bar\n\t\t{option>foo bar\n\t{/select>\n\t{p>\n\t{input type="text" name="mybox">\n{/form>\n\n\n{script language="JavaScript">\n\t//-----------------------\t\n\tfunction buttonsClick(butName) { // button handler\n\t\tif (butName=='removebut') {\n\t\t\t/////alert(document.mainform.mybox.value);\n\n\t\t\tselectedPosition = \n\ndocument.mainform.filterset.selectedIndex;\n\n\t\t\tpicked = \n\ndocument.mainform.filterset.options[selectedPosition].value;\n\t\t\t\n\t\t\talert('test 3: pos=' + selectedPosition + ' value=' + \n\npicked);\n\t\t}\n\t}\n{/script>\n\n\n(Less-thans substituted with curlie braces) ________________

Try closing the "option" tags

Tried that, no go
The original (with problem) had closings anyhow; I just rushed it for the sample when I substituted it with foo-bar stuff. I won't do it again.

Need a value attribute for the options
you've set the text for the options but assigned no value. \n <select name="filterset">\n <option value='foo'>foo\n <option value='bar'>bar\n <option value='foo bar'>foo bar\n </select>\n

Thanks, it worked!
However, it does bring up a couple of questions:
1. Why did it work in Mozilla without the Value tag?
2. How does one reference the description text in JS?

Mozilla probably defaults
Means that <option> is probably not treated the same as <option value=''>. Anyhow, it's not a behavior that should be relied upon. The text can be retrieved by using .text instead of .value. document.mainform.filterset.options[selectedPosition].text;

Can anybody recommend a good on-line JavaScript reference?
My dot-com-fire-sale books are getting outdated. Thanks for the tips.

Wikipedia?
[link|http://en.wikipedia.org/wiki/JavaScript|JavaScript] and [link|http://en.wikipedia.org/wiki/Ecmascript|ECMAScript]. They seem to be decent references with pointers to other sources.
HTH.
Cheers,
Scott.

Various References
I generally fallback on the O'Reilly [link|http://www.oreilly.com/catalog/dhtmlref2/|DHTML] and [link|http://www.oreilly.com/catalog/jscript4/|JavaScript] books. [link|http://www.dannyg.com/pubs/jsb/|Javascript Bible] is also good but after reading it, I rarely fall back to it for reference purposes. Anyhow, if you're in the market, those are probably the three best.
There's lots of web resources as well, but I usually just google and end up at random places. Two that I've bookmarked but don't use regularly are [link|http://javascript-reference.info/|Javascript crib] and [link|http://webref.info/default.asp?|WebRef].
