javascript - Proper deleting HTML DOM nodes -

-

i'm trying create star shining animation.

function showstars() {     //if ($('img.star').length > 5)     //  return;      var x = math.floor(math.random() * gameareawidth) - 70;     var y = math.floor(math.random() * gameareaheight);      var star = document.createelement("img");     star.setattribute("class", "star");     star.setattribute("src", imagespath + "star" + getrandom(1, 3) + ".png");     star.style.left = x + "px";     star.style.top = y + "px";     gamearea.appendchild(star);     // light.     settimeout(function () { star.setattribute("class", "star shown"); }, 0);     // put out.     settimeout(function () { star.setattribute("class", "star"); }, 2000);     // delete.     settimeout(function () { gamearea.removechild(star); }, 4000);      settimeout(function () { showstars(); }, 500); }

it works fine until uncomment following code supposed regulate star count:

//if ($('img.star').length > 5) //  return;

then stops work if created stars not removed (the first 5 stars blink nothing happens). why jquery selector select them after gamearea.removechild(star);? isn't enough remove them parent node?

browser: google chrome 17.

regards,

change commented out lines 

if ($('img.star').length > 5) {   settimeout(function () { showstars(); }, 500);   return; }

to keep showstars recursion going.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
