ext js4 code

model

ext.define ('mycomp.model.myclass',{     extend: 'ext.data.model',      fields:['textfieldone']  });

view

ext.define('mycomp.view.user.myclassview', {     extend: 'ext.window.window',     alias: 'widget.myclassview',     initcomponent: function() {         this.items = [             {                 xtype: 'form',                 items: [                     {                         xtype: 'textfield',                         name : 'textfieldone',                         fieldlabel: 'contact person name'                     }                 ]             }         ];         this.buttons = [                         {                             text: 'save',                             name:'save',                             action: 'save'                         }                     ];         this.callparent(arguments);     } });

controller

ext.define('mycomp.controller.myclass',{     extend: 'ext.app.controller',      stores:['myclass'],     models:['myclass'],     views:['myclassview'],     init: function(){         this.control({                       'myclassview button[action=save]': {                 click: this.mymethod             }         });                  },          mymethod: function(button, record) {         var win    = button.up('window'),            form   = win.down('form'),             values = form.getvalues(),            store = this.this.getmyclassstore(),            model = store.model,            record = model.create();              record.set( values );            store.add( record );            win.close();            store.sync();  } });

store

ext.define('mycomp.store.myclass',{     extend:'ext.data.store',     model:'app.model.myclass',      proxy: {         actionmethods : {             create : 'post'         },         type: 'ajax',         url : '/savetodb.php'      }  });

i think you'll want set .php file headers serve json:

header('cache-control: no-cache, must-revalidate'); header('expires: mon, 26 jul 1997 05:00:00 gmt'); header('content-type: application/json');

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...
