Re: Adding a filterer to FilteringTable widget

Wow, the filtering table is amazing!!  I was able to cobble together a
filter without much
problem.  I basically tied the "applyFilters" call to the onkeyup of a
textbox and specified a filter as you indicated.  (Autocomplete="off"
helps big time).  Here's my filter code, though know it is definitely
not optimized and doesn't deal with numeric values .... yet:

===============
function inspectRow(rowObj)
{
    if (!rowObj) return true;
    var filtText = document.myFilter.namefilter.value.toLowerCase();
    if (filtText)
    {
        var rObj = rowObj.toLowerCase();
        if (rObj.indexOf(filtText) >= 0)
        {
                return true;
        }
        else
        {
                return false;
        }
   }
   else
   {
        return true;
   }
}

After getting this working, I wanted to try to filter more than one
row at a time.  It was at this point that I realized I had to call a
seperate function to do this.  It would be really nice to be able to
send parameters to the filter function.  This way I don't have to
specify the filter input within the function itself.  Could there
possibly already be a way to pass parameters to the filter call?

Another minor detail is that you said that my filter would receive an
HTML Row as input when in fact it receives the data contained in the
column (i.e. Adam, David, etc ...).  This is actually much easier to
parse than a row so I vote you keep it as is.

Other than that, FilteringTable is definitely a marvelous piece of code.

Bravo,

Malaney
