Question

I have five rows in my table in html. Each row has only 1 td. I want to manipulate the table row background in a function. How do I refer to the table row in the function?

Answer 1

You can reference them by their ordinal index;

var tbl = document.getElementById("myTable");
var firstRow = tbl.rows[0];
...
tbl.rows[n].style.color = "red"; 
...
