jQuery's each function and array inside of it -

-

having trouble each function... try explain example...

in code, there div id "media-type-container-1", content changes "live", in runtime:

<div id="media-type-container-1">     <div><input type="checkbox">media 11<span id="media-stations-id-11" class="media-stations-id">11</span></div>     <div><input type="checkbox">media 12<span id="media-stations-id-12" class="media-stations-id">12</span></div> </div>

if changes, can chnanged ie:

<div id="media-type-container-1">     <div><input type="checkbox">media 13<span id="media-stations-id-13" class="media-stations-id">13</span></div>     <div><input type="checkbox">media 14<span id="media-stations-id-14" class="media-stations-id">14</span></div> </div>

to list of "media-stations-id" use following code:

$("#add-to-filter-stations").live("click", function() {      var selectedmediastations = new array();     selectedmediastations.length = 0;      $('#media-type-container-1').each(function(){         $('.media-stations-id').each(function(){             selectedmediastations.push($(this).attr('id').replace("media-stations-id-", ""));         })     }); }

in mentioned example, array selectedmediastations elements 11, 12, 13 , 14, instead of 13 , 14.

what i'm doing wrong, cannot "start" empty array every time live function?

why don't try 

var selectedmediastations = $('.media-stations-id').map(function(){     return $(this).attr('id').replace('media-stations-id-',''); });  // [13, 14]

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...
