Re: Prob with IE8 and getElementsByName()

Show all headers | View raw

Hi Denis (and others):

    Did some JS reading last nite (David Flanagan's 5th), and am going to 
make some changes to the way I implement the 5th table this morning:

    Because this table has a variable number of rows -- from 1 thru (I 
think) ten or so maximum,  and because I don't know the size of the table 
until my Ajax routine returns the response string of values for the rows and 
columns, I will now try to build the table in 'real time' as I parse the 
Ajax response.

    What I will do is prebuild only the <thead> section, then I'll add the 
<tr> rows and cells as I parse thru the responsetext..

    I haven't done this before but Flanagan explains the syntax of 
insertRow(), and insertCell(), and I'm going to give it a try.

    If it doesn't work out, I still have your guidance above to rescue me 
:))

Thanks !

-Mel
