                $(".csstdhighlight").removeClass("csstdhighlight"); // clear previous selection

Solution 1

I think you can do this by using many methods, one of them is to add a simple Attribute to selected cell like "isSelected='true'" by using jquery (like what you have do with CSS)

JavaScript

$(cell).attr("isSelected","true"); //(just example).

than filter by all TD that has isSelected=true if > 3, show your alert message
