jquery - Getting total count of JSON response -

-

can done in jquery before start looping through them? or need setup separate group in response of data total count lets say.. first variable?

the common response looks this:

 [    {"name":"tu\u011frul","surname":"topuz","message":"hello world"}    ,{"name":"tu\u011frul","surname":"topuz","message":"hello world"}  ]

but use jquery return 2 total count (before loop through them all?) or need this?

 [    {"total":"2"}    ,{"name":"tu\u011frul","surname":"topuz","message":"hello world"}    ,{"name":"tu\u011frul","surname":"topuz","message":"hello world"}  ]

whats efficient/common (optimization-wise) way of doing this?

as after json decoding getting array of objects(from have posted). can access length property of total count.

as have got array, assume have been able parse json response js object. can use datatype: 'json' tell jquery automatically or can parse using jquery.parsejson() necessary if set datatype:'json' or set content-type header application/json server.

so can this

$.ajax({       ....       datatype: 'json',       success(function(data){          if(data){           var total = data.length;           }       }  });

so dont need send total count server. can js after getting response , make easier traverse response using $.each whole array contains same type of objects (doesn't have special {"total":"2"} member).

note: length property pure vanilla js, has nothing jquery.

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...
