angularjs - Angular ui-router doesn't change location -

-

i have abstract state header , content (really app has layouts, simplified code example). header has filter , want change location url dynamically click on filter category. working stopped, , don't know why...

i use similar pieces of code:

$stateprovider     .state('root', {         url: '',         abstract: true,         views: {             '@': {                 templateurl: 'templates/layout.html',                 controller: 'layoutctrl'             },             'header@root': {                 templateurl: 'templates/header.html',                 controller: 'headerctrl'                 }         }     })     .state('root.index', {         url: 'index?{filter}'     }) });   (function() {     'use strict';      test.app.controller('layoutctrl', ['$scope', '$state' function($scope, $state) {         $scope.params = $state.params;          $scope.$on('params.changed', function($event) {             $state.go($state.$current, $scope.params);             // tried use             // $state.go($state.current.name, $scope.params);         });     }]);  })();  (function() {     'use strict';      test.app.controller('headerctrl', ['$scope', '$state' function($scope, $state) {         // event handler tasks , rewrite $scope.params         $scope.params = {             filter: [1, 2, 7, 15]         };         // tried sent new data in event params         $scope.$emit('params.changed');     }]);  })();

but didn't understand, why ui state router doesn't change location.

it work on plnkr because there no mistake - in togglefilter function did $state.params = newparams; , ui-router didn't change becase parameters same.

i think example ui-router using:

    angular.module('myapp', [   'ui.router' ]) .config(function($stateprovider, $urlrouterprovider) {      $urlrouterprovider.otherwise('/index?filter=1');      $stateprovider         .state('root', {           url: '',           abstract: true         })         .state('root.base', {           url: '',           abstract: true,           views: {             '@': {               templateurl: 'layout.html',               controller: 'rootcontroller'             },             'header@root.base': {               templateurl: 'header.html',               controller: 'headerctrl'             }           }         })         .state('root.base.1', {           url: '/index?{filter}'         }) }) .controller('rootcontroller', function($scope, $state){   // when went page filter = 1   // object filter = 1   $scope.params = $state.params;   $scope.$on('filter.changed', function($event, data) {     $scope.params = data;     console.log($scope.params);     $state.go($state.$current, $scope.params);   }); }) .controller('headerctrl', function($scope){   $scope.filters = [     {       key: '1',       value: 1,       selected: false     },     {       key: '2',       value: 2,       selected: false     },     {       key: '3',       value: 3,       selected: false     },     {       key: '4',       value: 4,       selected: false     },     {       key: '5',       value: 5,       selected: false     }   ];    $scope.togglefilter = function(filter) {     filter.selected = !filter.selected;      var selectedfilters = [],         filterlength = $scope.filters.length;      (var = 0; < filterlength; i++) {       $scope.filters[i].selected && selectedfilters.push($scope.filters[i].value);     }      $scope.$emit('filter.changed', {       id: 1,       filter: selectedfilters     });   }; }) .run(function($rootscope, $location) {   $rootscope.$on('$statechangesuccess', function(event, tostate, toparams, fromstate, fromparams) {     console.log(fromstate);     console.log('$statechangesuccess');     console.log($location.absurl());     console.log(tostate);   }); })

any ideas when firefox implement lengthadjust andtextlength?..... working svg application. lengthadjust , textlength working fine in chrome not working in fire fox . <svg viewbox = "0 0 500 300" version = "1.1"> <defs> <path id="s3" d="m 10,90 q 100,15 200,70" /> </defs> <g> <text font-size = "20"> <textpath xlink:href="#s3" textlength="205"> short text</textpath> </text> <use xlink:href="#s3" fill="none" stroke="black" stroke-width="1"/> </g> </svg> this implemented in firefox text elements (not textpath or tspan) in case that's ok though can move attribute text element. <svg viewbox = "0 0 500 300" version = "1.1"> <defs>

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11
