williswin :
I have an HTML table that has some static data and some from MySQL. It is currently filtering properly, what I need help is adding the "yes" and "no" selections to the selection list. These are just test values, they are being read from MySQL. I am unable to figure out what values to insert here to add values from MySQL to the selection list. Any assistance will be appreciated! Thank you

Not showing yes and no options.
Nawed Khan :
Your filtering logic and odd/even row coloring logic is called BEFORE the data returns from your ajax even though it appears AFTER on the page/code. This is how async methods work.
You need to call the header and coloring logic inside the drawTable() function after, of course, you are done drawing the table... like this:
function drawTable(data) {
for (var i = 0; i < data.length; i++) {
drawRow(data[i]);
}
$('#myTable').initRowClasses('odd', 'even');
$('.dropdown-header').tableFilterHeaders(filterText);
}
Make sure to remove the foloowing 2 lines of code:
$('#myTable').initRowClasses('odd', 'even');
$('.dropdown-header').tableFilterHeaders(filterText);
from your code, wherever elsewhere they appear. Leaving them will not break anything, it will just run multiple times unnecessary.
