Angular – ui-grid – Dynamically Changing The File Name when Exporting CSV/PDF File

September 20, 2015

Hi guys, here’s a quick tip for dynamically changing CSV or PDF file name. Trying to make this work comes with a price, there are couple of steps you need to make before you can change the file name.First of all you need to inject uiGridExporterService service that holds all the export methods like load data, get column headers, get export data object ,CSV content and finally you can call the downloadFile function that accepts file name as a first argument. Example: var app = angular.module('app', );app.controller('MainCtrl', ['$scope','uiGridExporterConstants','uiGridExporterService', function ($scope,uiGridExporterConstants,uiGridExporterService) { $scope.exportCSV = function(){...

February 12, 2015

Angular – Numeric Control Directive

July 3, 2014

in one of LogoUi’s projects we had a requirement for  a numeric input type.My first thought was using an HTML5 input type number . Example: <input type="number" min="1" max="5"> The problem was that not all browsers has support for HTML5 input types.Check this site for more information about HTML5 forms browser support . so as a solution I decided to do 2 things: A) Use jQuery Spinner (numeric) widget which solves my cross browser compatibility issue.B) Wrap the widget as an Angular directive. Final Result: You can find my source code and more examples regarding Numeric directive in my GitHub page. Enjoy!

ng-grid – Dynamically Setting Group by One or More Fields

June 17, 2014

in one of LogoUi’s projects we had a requirement for dynamically grouping data,  trying to dynamically group data using the group property , is ignored, so after examining the ng-grid internal code, i found a solution. Setting group by one field for grouping by one field, in grid options object you need to call the groupBy function and pass the field as a string argument . Example:html: <div ng-controller="MyCtrl"> <button type="button" ng-click="changeGroupBy('name')">Group By Name</button> <button type="button" ng-click="changeGroupBy('age')">Group By Age</button> <div class="gridStyle" ng-grid="gridOptions"></div> </div> JavaScript: app.controller('MyCtrl', function($scope) { $scope.myData = [{"name": "Moroni", "age": 50}, ...

ng-grid – Single Row Selection for Multiple Checkbox Plugin

May 5, 2014

After working with ng-grid for awhile, I realized that single selection property is missing on configuration options when  multiple checkbox select (“select all” checkbox) is needed.I know it’s confusing, so lets take one step at a time and demonstrate what i mean, we’ll take a simple ng-grid and add the showSelectionCheckbox property. $scope.gridOptions = { data: 'myData', showSelectionCheckbox: true };   Live example: as you can see by default you have a multiple select but it’s not the desired result since we want a single row select, okay, so lets add the multiSelect property and set it to...

AngularJS – $$postDigest vs $timeout when DOM update is needed

April 8, 2014

When you need to update the DOM once after dirty checking is over or in other words, fire a callback after the current $digest cycle completes,you can use $$postDigest or $timeout.I’ll try to explain the cons and the pros of  $$postDigest and $timeout. $$postDigest  pros:          1. Fires a callback after the current $digest cycle completes.          2. Great for updating the DOM once after dirty checking is over. cons:          1. $$ means private to Angular, the interface is not stable. usage: //runs immediately after $scope.$digest$scope.$$postDigest(function(){ console.log("post Digest"); }); * it should be noted that...

AngularJS – Why does $scope.$apply affect other scopes and how it affects performance?

March 29, 2014

as you can see from Angular’s $apply pseudo-code: function $apply(expr) { try { return $eval(expr); } catch (e) { $exceptionHandler(e); } finally { $root.$digest(); } } Internally angular does the following: $scope.$apply = $rootScope.$digest //+ some error handling and since $scope.$apply uses $rootScope, it affects all its descendants by dirty-checking EVERY data-bound objects, it’s crazy,...

AngularJS – $watch for changes in specific object property when watching an array

March 26, 2014

When deep $watch is needed on an array, but not for the entire object, you can strip off irrelevant data, this way you make the comparison much faster. Example: (solution by Karl Seamon) $scope.$watch(function($scope) { return $scope.listOfBigObjects. map(function(bigObject) { return fieldICareAbout; }); }, myHandler, true); this way you watch only what you need. Live example for watching only for "name" property: hope you’ll find this post helpful.
