问题 Using VS2010 VB.NET, I have a datagridview (dgv) where I set the background color of cells according to a certain value.

My current attempts are a complete failure and MSDN is only particular to "setting" and not "getting" the background color of a cell.

问题 I am trying to get the td values using jQuery for a table I have no control over. There is an excellent example posted on this site, but it references one column not multiple ones within each tr. I also don't have an id for the table or rows... only a class=columndata for the td. $('#mytable tr').each(function() { var customerId = $(this).find("td").eq(2).html(); } will get the single td of a fixed tr?
