javascript - How to detect more then 2 second the touchscreen was pressed? -

-

using google chrome , canary.

how detect more 2 second touchscreen pressed? (with mouse works real-touch screen failing, tested on surface pro 3)

$(document).ready(function() {    var clickstart;   var clickstop;    $(document).bind('contextmenu', function()  {     console.log('touch screen, has no right click.');     return false;   });    $(document).mousedown( function() {     return false;    });    // usb mouse pointer works, real-touch screen not working   $('#vip_anytime').on('mousedown', function(e) {           clickstart = e.timestamp;   }).on('mouseup', function(e) {       clickstop = e.timestamp- clickstart;       if(clickstop >= 2000) {         console.log('>>> after 2 second of hold');       } else {          console.log('>>> before 2 second of hold');       }   });  });

try touchstart , touchend events.

    $('#vip_anytime').on('touchstart', function(e) {             clickstart = e.timestamp;     }).on('touchend', function(e) {         clickstop = e.timestamp- clickstart;         if(clickstop >= 2000) {           console.log('>>> after 2 second of hold');         } else {            console.log('>>> before 2 second of hold');         }     });

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

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...
