Interest in touch screen devices really picked up momentum with Apple s release of the iPad in the spring of 2010, so I couldn t resist adding a bonus 101st plug-in to this collection Here s the final plug-in, which allows you to touch-enable a web page Figure 13-8 shows a copy of the web page for Plug-in PHP, a companion book to this one, in which a small frame has been attached to the top of the browser window with links to turn touch-enabling on and off

db iid flag oldmousex & oldmousey tempmousex & tempmousey MOUSE_X & MOUSE_Y MOUSE_IN onmousedown & onmouseup StartTE() DoTE() StopTE() PreventAction() setInterval() clearInterval() scrollBy() Local variable used as shorthand for documentbody Local variable containing the result of calling setInterval() to be used later when calling clearInterval() Local variable set to true when touch enabling is on Temporary copies of MOUSE_X and MOUSE_Y to save the mouse position when StartTE() is called Temporary copies of MOUSE_X and MOUSE_Y used in DoTE() to see if the mouse has moved Global variables containing the location of the mouse cursor Global variable set to true if the mouse is within the bounds of the browser, otherwise false Events of the document body that trigger when the mouse is clicked and released Subfunction to begin touch enabling Sub-subfunction to scroll the document as required Subfunction to turn off touch enabling Plug-in to prevent the default action of an event Function to set up repeated interrupts to another function Function to stop repeated interrupts Function to scroll the document body by a specified amount
How It Works
This plug-in starts by making a copy of documentbody in the local variable db, thus creating a shorthand reference to shorten the code:
var db = documentbody
The state argument is then tested and, if it is 1 or true, touch enabling is being turned on, so the variables iid and flag are initialized, PreventAction() is called to disable the default actions for drag and select operations on the document body, and the onmousedown and onmouseup events of the document body are attached to the StartTE() and StopTE() subfunctions, as follows:
var iid = null var flag = false PreventAction(db, 'both', true) dbonmousedown = StartTE dbonmouseup = StopTE
If state is 0 or false, then touch enabling is to be turned off, so PreventAction() is called to restore the default actions for drag and select operations on the document body, its onmousedown and onmouseup event hooks are removed, and the plug-in returns:

Solutions to Common problems
PreventAction(db, 'both', false) dbonmousedown = '' dbonmouseup = '' return
The StartTE() Subfunction
This function first checks the flag variable to see whether touch control has already been enabled If it has, false is returned; otherwise, copies of the mouse cursor position are placed in temporary variables to compare later to see if the document body should be scrolled, like this:
var var var var oldmousex oldmousey tempmousex tempmousey = = = = MOUSE_X MOUSE_Y MOUSE_X MOUSE_Y
Next, flag is set to true to indicate that touch control has been enabled, and setInterval() is called to set up repeating interrupts to DoTE():
flag = true iid = setInterval(DoTE, 10)
The DoTE() Sub-subfunction
This function first checks whether the mouse button is currently held down and is within the bounds of the browser, like this:
if (MOUSE_DOWN && MOUSE_IN)
If the mouse button is either not down or not within the browser s bounds, the StopTE() subfunction is called to release the current scroll Otherwise, a test is made to see whether the mouse has moved from the position that was stored in the variables tempmousex and tempmousey when StartTE() was first called:
if (MOUSE_X != tempmousex || MOUSE_Y != tempmousey)
If the mouse has moved, tempmousex and tempmousey are updated to the new mouse location, like this:
