JavaScript Function Issue (dates) -


i'm having issues javascript code. need make code following:

  1. click image twice within 3 seconds make image disappear
  2. click once reappear

i've got close working...i'm having issues date. don't know how keep date first click. code right creating new start date each click don't want.

code far:

var imgnext = -1; var start = new date ( );  function disappear () {  var end = new date ();  imgnext++;  if (imgnext == 2) {     document.getelementbyid("mypicture").style.visibility="visible";     imgnext = -1; } if (imgnext == 1 && (end-start <3000)) {     document.getelementbyid("mypicture").style.visibility="hidden"; } start = new date ();

}

in code image changes if clicks on 3 seconds apart because i'm creating new start date every time function triggered. how resolve this?

cheers.

here answer, working example: http://jsfiddle.net/ys5bs/2/

document.getelementbyid("disappear").onclick = function() {     var lastclick = this.attributes["click-time"],         click = new date().gettime(),         timeout = parseint(this.attributes["data-timeout"].value);          if(lastclick && (click - lastclick) < timeout && this.style.opacity == 1) {             this.style.opacity = 0;             this.attributes["click-time"].value = null;             return;         }         else {             this.attributes["click-time"] = click;         }          if(this.style.opacity == 0) {             this.style.opacity = 1;             this.attributes["click-time"] = null;             return;         } };

basically assigning onclick, , getting click times, if within set timeout (milliseconds) hides, otherwise, shows again, per spec
