[thelist] JavaScript: style.display

[Ken Schaefer]

Or you could have the server-side ASP for the parent page either:
a) write out some javascript to change the display state of that <tr> after
the page has loaded
	-or-
b) as it dynamically generates the table, set the <tr> display state
appropriately

Well, that's part of your problem. A fully client-side solution probably
isn't best. However, you could do this fully client-side by saving the
state in cookies. Maybe a series of bits (or the hexidecimal
representation if you're worried about the cookie filesize limitation).

e.g.:

tableState=0000000000010010000001010000000000000100000000100100010100000001

Then you would reconstruct the state onload setting all tr's to
display='none' where its respective bit is 0 and display='' where its
respective bit is 1.

Something like (pardon me if I intermingle JavaScript and Java syntax --
but this is the general idea):

// where mycookie is a string with the value of tableState cookie above
var trs = document.getElementById('mytable').getElementsByTagName('tr');
for (var i=0; i<trs.length; i++) {
    if (mycookie.charAt(i)=='0') {
        trs[i].style.display = 'none';
    }
    else {
        trs[i].style.display = '';
    }
}
