UG!!! I am trying to learn this but, I just cannot get it right!!!

I am trying to dynamically generate “x” number of html tables filled with up to 100 lines of data each.

I can get the table count needed, I can loop, I can add but, one thing is for sure: I CANNOT WRITE CODE.

Here is the result wanted:

1- I have 1027 lines of data from an array.

2- I want my script to make 11 html tables with up to 100 lines each. ((Layers actually) which by default will be not visible via css. That way I can do some show hide on the tables like a “next prev” navigation. I don’t need help with the cross browser css.)

3- IF there is a better way, a method that I can comprehend anyhow, other than using visible= method, please elaborate!

I gave up trying to have Perl make pages of 100 with “next prev” links to the data so I resorted to using css javascript onclick=yadayada to “display the data”.

I thought it would be easier to shift off 100 lines of the array in a loop and put the lines in their own html tables. Not.

I have failed miserably and need assistance.

Answer 1

my $cnt = 0;

while (@array) {
    my @rows = splice @array, 0, 100;
    print qq(<table id="t$cnt">\n);
    for my $row (@rows) {
        print "<tr><td>$row</td></tr>\n";
    }
    print "</table>\n";
    ++$cnt;
}

You may want to use HTML::Table for generating HTML.
