What is your main target about button if you want to create multiple buttons try this

If Not then re send your Question

Answer 2

Oh, just give all buttons same class or name and then bind click on that class. Like this $(".buttons").on("click", function (){
//Your logic here
})
If that is a table, where buttons are? If yes, you can use $(this).closest("td") or ...closest("tr") and get indexes from them
And if you are using jQuery then don't ever go so complicated, because jQuery is made for simplicity

Qudusayo I have created 42(6×7) buttons with different ids. I wnat to check which specific button was clicked to change its colour (actually it's column's lowest cell colour).
