Add a meta tag. Note the Intelli. Sense dropdown list of options. CSD 340 (Blum) 10

is also Intelli. Sense for the tag attributes, choose name. There CSD 340 (Blum) 11

Finish the meta tag. Notice the color coding brown for tag name, red for attribute name, blue for attribute value, green for comment. CSD 340 (Blum) 12

If one places the cursor in or between the body tags, then the document’s properties appear in the Properties Window. If the Properties Window is not present go to View/Properties Window on the menu. One can view the properties of other items by selecting them from the Properties Window’s drop-down list. CSD 340 (Blum) 13

Set the Cell properties. CSD 340 (Blum) 32

Result in Design CSD 340 (Blum) 33

Result in Source. CSD 340 (Blum) 34

Place the cursor inside the first cell and double click on the Image button on the Toolbox. If you don’t have the Toolbox, go to View/Toolbox. To keep the Toolbox in place, click on the icon that looks like a tack (look near the top of the Toolbox). CSD 340 (Blum) 35

One should be able to click on the ellipsis button that appears after placing the cursor in the Src Text. Box, but I had problems which I reported to IT. CSD 340 (Blum) 36

Go to Source and type the file name including the extension. The file should be in the same folder as Memory. htm. CSD 340 (Blum) 37

It’s too big, better add a width attribute. CSD 340 (Blum) 38

Added image attributes. <img src="Memory. gif" id="Card 11" width="100" alt="memory card image"/> width: To control the size of the image. (There is also a height attribute, but if only the width is assigned, the aspect ratio of the original image will be maintained. ) id: So we can distinguish one thing from another. alt: Some text in case an image cannot be found. May also be used by visually impaired users. CSD 340 (Blum) 39

Result in Design. Next copy image code into each cell. The ids must be changed. No two ids can be the same. CSD 340 (Blum) 40

Result of adding image tags to each cell. CSD 340 (Blum) 41

Result in Design. CSD 340 (Blum) 42

Adding a click event to the image tag. Now when user clicks the first image The function Flip. Card 11 is called. We must now define it! CSD 340 (Blum) 43

Start adding a script tag in the <head> region. CSD 340 (Blum) 44

Write an alert just to test the calling of the function. CSD 340 (Blum) 45

CSD 340 (Blum) 46

Security message about scripts CSD 340 (Blum) 47

Security Warning (Cont. ) CSD 340 (Blum) 48

Result of user clicking on first image. CSD 340 (Blum) 49

Replace test code with more realistic code CSD 340 (Blum) 50

New result of user clicking. CSD 340 (Blum) 51

Add a double click event for the first card. CSD 340 (Blum) 52

Add a function to “handle” the double click event. CSD 340 (Blum) 53

A possible, but tedious way to continue. • To finish the game, one could write 17 more click functions and 17 more double click functions. But there’s a better way using arguments. CSD 340 (Blum) 54

Add arguments to function calls. CSD 340 (Blum) 55

Add arguments to the function definitions CSD 340 (Blum) 56

The benefit of arguments • The benefit of the arguments is now the function definition is generic – it does not specifically refer to the image id, and it does not specifically refer to the image file name. • This way we can use the same function definition and just get the desired changes in behavior by calling the function with different arguments. CSD 340 (Blum) 57

New function call, old function definition. CSD 340 (Blum) 58
