How to control <span> for <tr>?

Note that span is for inline elements, so for Jester's first example, you should use div instead to wrap around a table, which is block-level.

ok...thanks for the clarification snoyes_jw
 

Thanks for the info.  What's the best way to control set of <tr>.  Basically, I want to hide or display 3 <tr> at once.  I tried <div>, it seems work just like <span>.  No effect on <tr>.  Certainly I can set individual <tr> display style but it will be cumbusom to do so.  Is there anyway I can control a set of table row in one call?

Thanks,

Thanks for all the answers.  One more question.  I tried most of the solutions, all my tries works for IE but not Mozilla.  Is there any solution that can work for both browsers.

Thanks,

It should work on Mozilla too. However, you can do a document.all and document.layers test to see what browser it is running on. I believe that script shoudl work on Mozilla too. Are you using an old version of Mozilla?

I tried on Mozilla Firefox 0.9, pretty latest.  Not working.  The requirement is for both IE and Netscape 7.0.1.  I'll test on it too.  I tried something a few days ago.  No go there either.

Really? That's odd, I put up the exact same code I posted in a test page (http://www.freewebs.com/dakyd/ee/test.html) and it works fine in Mozilla 1.7.  And Firefox should be able to handle a simple getElementById, which is pretty much what all of our solutions use.  

Is there something I'm missing?  Do you expect behavior other than just simply hiding the rows?

OK, the part not working on Mozilla is to dynamically set the style.  For example, in javascript, I have something like  document.getElementById("fieldName").style.display="none".  It's working in IE, but not in any of the Netscape or Mozilla browser.

Thanks,

I'm still not following - if you can access the object with document.getElementById, then hiding it with a style.display = "none" should be fine.  That's what all the suggestions (except for justinbillig's) use, and if you can hide the rows on the test page I posted, then it's working fine.

Am I correct in assuming it's not the sample scripts we have posted that you're having problems with?  If so, why don't you post either the source or a link to it so we can take a look?  Otherwise, do you get javascript errors?

dakyd, my bad.  I didn't copy the code from here.  But I follow the concept you guys suggest but no work for Mozilla.  Now I found the reason.

Basically I use the code mentioned in "JavaScript Bible", such as document.all["innerSpan"].style.display="none".  It works perfectly fine in IE but not in Netscape and Mozilla.  Now if I change it to "document.getElementById("innerSpan").style.display="none", it starts to work for both.  So document.all["id"] only works for IE.  This is the lesson to learn.  I should use the wrapper API to access the html object instead of using the array directly.  Thanks for everybody's patience.

Thanks for everyone's input.  It's a great discussion.  -Dennis

Yup, that'll do it.  document.all was/is an IE-only addition, and document.getElementById is the standards-compliant way of accessing elements in the DOM.  Anyhow, glad to hear you got what you wanted, and thanks for the points.

there is one snafu with mine i found out on friday at like 5 but couldnt fix real quick, if you press hide more than once it will overwrite the origional code with the &nbsp;

so a little bit of button enable disable should fix that
