javascript - Roll hover image -

-

i searched on internet lot couldn't find useful link. trying develop custom menu.

it needs area-based rollover menu changes depending on part of image being hovered on user. image , related link needs change depending on area of image user hovering over. check below image: close box

after clicking next image below one, open box

lastly when hover on specific slice of pizza, image should changed accordingly. example below image:

enter image description here

is possible css3, javascript?

there's 2 different ways think of. since tagged jquery i'm assuming that's acceptable. pagex , pagey track mouse movements on screen , can used determine area of screen being hovered over. here's fiddle made determine coordinates: http://jsfiddle.net/cpk3mqxw/

$("#image").mousemove(function (e) { mousex = e.pagex; mousey = e.pagey; $("#update").text("x: " + mousex + " y:" + mousey); });

edit: checking coordinates, need think of page grid system, per usual javascript, , gauge if mousex more 132 , less 155 must on part of image. again, separate span tag updated x , y coordinates helpful. a.e: 

if(mouse x >= 102 && mousex <= 220 && mousey >= 26) { //do }

it pays off in end, quite bit of work. way use image map. 

<img src="image.jpg" id="image1" usemap="#one"> <map name="one"> <area coords="30, 50, 70, 100" href="gohere.html"> </map>

and if you'd area highlighted or styled can use maphilight.js can find more information on here: http://davidlynch.org/blog/2008/03/maphilight-image-map-mouseover-highlighting/

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
