Web Activity 8 - Guidance ========================= createBoard() function ---------------------- Use nested "for" loops to iterate through the "board" table in row-by-row order. Each row has the same number of columns (cells). Each of these cells is a td, which represents a checkerboard square. As you iterate through these squares, let "square" be a local variable that refers to the current cell: var square = board.rows[iRow].cells[iCol]; For each square: Change the square's background color to either black or red. Here is an "if" condition that identifies a black square: if ((iRow + iCol) % 2 != 0) Make sure you understand why/how this works. Here is how you can change a black square's background color: square.style.backgroundColor = "black"; For each black square, register an onclick handler as follows: square.onclick = onClickBlackSquare; onClickBlackSquare() event handler function ------------------------------------------- If the user clicks on the checker image, since there is no event handler registered on the image, the event bubbles to its parent td (the black square that contains the image). In this case, the source of the event is the image. Check to see if the source of the event was the checker image. if (source.tagName == "IMG") If it is from the checker image, remove the image from the square as follows: source.parentElement.innerHTML = ""; Then return from the handler. If the source was not the image, then add a checker image to the square: source.innerHTML = "";
