javascript - Backbone Fetch Request is OPTIONS method -

-

i have backbone collection object following url "http://localhost:8080/api/menu/1/featured". trying perform fetch operation retrieve collection url , parse it. however, on server side, method type see request options. server suppose support method. not sure how backbone figuring out method type use, , why changes options method type randomly sometimes. using node.js server process request. code below pretty did.

var featuredcollection = backbone.collection.extend({     model:featuredcontent,     url:function () { return url_featured; },     parse:function (response) {         console.log(response);         return response;     } });  var featuredcollection = new featuredcollection(); featuredcollection.fetch();

please help, thanks!

it's been awhile, remember coming across before. there's 2 things be: backbone default tried restful api calls backend, means get, post, put, , delete.

many backends weren't built real rest support , support , post. when backbone sends put or delete command browser (not backbone) automatically sends options request first see if it's allowed make these kinds of requests. if server answers improperly call fail , backbone won't anything.

to around set backbone.emulatehttp = true; or have server answer options calls. see documentation more info: http://backbonejs.org/#sync-emulatehttp

the other issue you're making ajax requests cross-domain / sub-domain , need enable cors. includes answering options requests.

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...
