i want format input in form of number in edittext.the format 01-133134-124. wanted first - after 2 number next dash after 6 numbers.i tried whenever pressed delete/backspace because of wrong entry format stopped working , no dash placed after input of 2 number or 6 numbers.here code.where enrollement edittext field.

format : 2digitnumber-6dignumber-3dignumber

enrollement.addtextchangedlistener(new textwatcher() {      @override     public void ontextchanged(charsequence s, int start, int before, int count) {          enrollement.setonkeylistener(new view.onkeylistener() {             @override             public boolean onkey(view v, int keycode, keyevent event) {                  if (keycode == keyevent.keycode_del)                     keydel = 1;                 return false;             }         });          if (keydel == 0) {             int len = enrollement.gettext().length();             if (len == 2) {                 int leng = enrollement.gettext().length();                 if(leng==2) {                     enrollement.settext(enrollement.gettext() + "-");                     enrollement.setselection(enrollement.gettext().length());                 }                 } else if (len == 9) {                 int leng = enrollement.gettext().length();                 if(leng==9) {                     enrollement.settext(enrollement.gettext() + "-");                     enrollement.setselection(enrollement.gettext().length());                 }             }         } else {             keydel = 0;         }     }      @override     public void aftertextchanged(editable arg0) {      }      @override     public void beforetextchanged(charsequence arg0, int arg1, int arg2, int arg3) {      } });

it easier if changed approach bit. analyzing unformatted verion of string after every single change in edittext.

try (remember set android:maxlength="13" edittext):

enrollement.addtextchangedlistener(new textwatcher() {      final int[] blocklengths = new int[]{2, 6, 3};     string munformatted = "";      @override     public void ontextchanged (charsequence s,int start, int before, int count){         string unformattedseq = s.tostring().replace("-", "");         if (munformatted.length() == unformattedseq.length()) {             return; //length of text has not changed         }          munformatted = unformattedseq;         //formatting sequence         stringbuilder formatted = new stringbuilder();         int blockindex = 0;         int currentblock = 0;         (int = 0; < munformatted.length(); ++i) {             if (currentblock == blocklengths[blockindex]) {                 formatted.append("-");                 currentblock = 0;                 blockindex++;             }             formatted.append(munformatted.charat(i));             currentblock++;         }          enrollement.settext(formatted.tostring());         enrollement.setselection(formatted.length());     }      @override     public void beforetextchanged (charsequence s,int start, int count, int after){     }      @override     public void aftertextchanged (editable s){     } });

this code should work correctly. improve setselection part (currently if delete number in middle of edittext move cursor end of text).

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
