ajax - Spinner on a window -

-

i have window has treeview nodes , sub-nodes. when copy subnode/node , try paste node, window tends unresponsive. , once paste completed, refreshes destination paste. functionality takes place below.

now how can show spinner between copy , paste such window treeview becomes faded , displays spinner until paste completes. appreciated.

$.ajax({     type: 'post',     url: '/test.aspx',     data: data,     success: function(result) {         refresh(id);         if (result != "success") alert("copy failed");         else {             alert("successfully copied");         }     } }); 

$("#divprogress").html("<img src='yourimg.gif' alt='loading..' />").fadein(100,function(){     $.ajax({      type: 'post',      url: '/test.aspx',      data: data,      success: function(result) {         $("#divprogress").fadeout(300,function(){               refresh(id); // not sure does!!! ...??               if (result != "success")                {                  alert("some error!");               }               else               {                  alert("successfully copied");               }         });      }   });  });

assuming divprogress div want show loading image , spinning image name yourimg.gif. may need change image path according scenario.

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...
