angularjs-ng-repeat

I recently got the console error ` Error: [ngRepeat:dupes] duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys... — AngularJS Error Reference - ngRepeat:dupes which I then used 'track by $index' and the issue was solved... But that got me thinking... is there a reason why you wouldn't want to use track by $index in an ng-repeat? I've read SO questions like this one as well as other articles , but it seems like almost all of the articles only talk about the advantages of using 'track by' . Can someone list the disadvantages and give an example of when you

I have a $scope.myData object that contain a chunk of data. What i am trying to do is display the data but filter out the nulls and empty strings: $scope.myData = [ { "ID" : "001", "Message" : "test test test test" }, { "ID" : "002", "Message" : "test test test test" }, { "ID" : "003", "Message" : "test test test test" }, { "ID" : "004", "Message" : "test test test test" }, { "ID" : "005", "Message" : " " }, { "ID" : "006", "Message" : "test test test test" }, { "ID" : "007", "Message" : "test test test test" }, { "ID" : "007", "Message" : null } ] I can perform an ng-repeat on the above and

Angular Documentation says: - The compilation of the DOM is performed by the call to the $compile() method. The method traverses the DOM and matches the directives. If a match is found it is added to the list of directives associated with the given DOM element. Once all directives for a given DOM element have been identified they are sorted by priority and their compile() functions are executed. The ng-repeat directive I believe has a lower priority than custom directives, in certain use cases like dynamic id and custom directive . Does angular permit tinkering with priority of directives to

Is it possible to filter an array of objects, such that the value of property can be either of a few values (OR condition) without writing a custom filter This is similar to this problem - Angular.js ng-repeat :filter by single field But instead of <div ng-repeat="product in products | filter: { color: 'red' }"> is it possible to do something like this <div ng-repeat="product in products | filter: { color: 'red'||'blue' }"> for a sample data as follows- $scope.products = [ { id: 1, name: 'test', color: 'red' }, { id: 2, name: 'bob', color: 'blue' } /*... etc... */ ]; I've unsuccessfully tried

I'm trying to filter some list items based on the value of a boolean property, but no matter what I do the entire list is always displayed. A few of the the things I've tried have been so broken that nothing displays, but that's neither here nor there. I can't get my filtering working as desired: $scope.attendees = [ {"firstname":"Steve", "lastname":"Jobs", "arrived":true, "id":1} ,{"firstname":"Michelle", "lastname":"Jobs", "arrived":false, "id":2} ,{"firstname":"Adam", "lastname":"Smith", "arrived":true, "id":3} ,{"firstname":"Megan", "lastname":"Smith", "arrived":false, "id":4} ,{"firstname
