php - Timestamp a Variable being returned -

-

i little slow when comes jquery trying footing in language. working faceapi , have working beautifully. during recognize phase have ajax call returns array of info. 

$.ajax({                  url: 'http://api.face.com/faces/recognize.json?&uids=all&namespace=camera_app&detector=aggressive&',                  data: formdata,                  cache: false,                  contenttype: false,                  processdata: false,                  datatype:"json",                  type: 'post',                  success: function (data) {                      photo = data.photos[0];                      handleresult(photo)                  },

but interested in "uids" called api matches person's face uid. want know once uid returned can timestamp placed , saved database have setup? [sidenote: users photos submitted api, not save them on database. thing saving users first/last name , uid.] don't know how timestamp function work returning variable.

i want able pull @ later date uid , timestamp matching when information returned.

update:

here uid , accuracy (confidence) displayed user:

function handleresult(photo) {     console.log(photo)     var s = "<h2 class='results'>account information:</h2>";     if(photo.tags.length) {       var tag = photo.tags[0].uids[0];       s += "<p>";      //$('#result') .html ('welcome back:' + photo.uid + ',' + 'confidence:' + photo.confidence);      if(tag.uid) s += "<li> user:" + tag.uid + "</li>";      if(tag.uid) s += "<li> accuracy:" + tag.confidence + "%" + "</li>";      if(tag.uid == 0) s += "i got something, data wasn't clear. sorry.";       } else {         s += "<p>sorry, didn't find faces.</p>";       }       $("#result").html(s);

at stage timestamp created.

solved: 

function handleresult(photo) {     console.log(photo)     var s = "<h2 class='results'>account information:</h2>";     var month = new date().getmonth() + 1;     var day = new date().getdate();     var hours = new date().gethours();     var min = new date().getminutes();     var suffix = "am";     if (hours >= 12) {     suffix = "pm";     hours = hours - 12;     }     if (hours == 0) {     hours = 12;     }     if (min < 10)     min = "0" + min      if(photo.tags.length) {       var tag = photo.tags[0].uids[0];       s += "<p>";      //$('#result') .html ('welcome back:' + photo.uid + ',' + 'confidence:' + photo.confidence);      if(tag.uid) s += "<li> user:" + tag.uid + "</li>";      if(tag.uid) s += "<li> accuracy:" + tag.confidence + "%" + "</li>";      if(tag.uid) s += "<li> timestamp:" + month + "/" + day + "&nbsp;" +  hours + ":" + min + suffix + "</li>";      if(tag.uid == 0) s += "i got something, data wasn't clear. sorry.";        } else {         s += "<p>sorry, didn't find faces.</p>";       }       $("#result").html(s);

you can create timestamp in handleresult callback using date function.

var timestamp = math.round( new date().gettime() / 1000 )

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...
