问题 I am going to have a contextmenu directive in ng-repeat items. Based on whether a condition is true, the directive should be applied. How do I put a condition like only when item.hasMenu == true then apply the directive ? <ul ng-controller="ListViewCtrl" > <li contextmenu ng-repeat="item in items">{{item.name}} </li> </ul> EDIT This seems to have worked for me. First the directive. app.directive('menu',function(){ return { restrict : 'A', link : function(scope,element,attrs){ if(scope.hasMenu

问题 I neeed an input field where I can enter only the values 1,2 or 3 so i'm trying to build a directive which prevents all changes to the model if it doesn't match these values. eg the value is 1 and I change it to 5 it should be still 1. I've put together a small fiddle http://jsfiddle.net/kannix/Q5YKE/ but it's most likely wrong to use the $parsers. app.directive('myvalidator', function () { return { require: 'ngModel', link: function (scope, elm, attrs, ctrl) { var validValues = [1,2,3]; ctrl

问题 I created a directive in order to make a input that has width automatically resized when keyup (like Google Contacts). However it seems not to be ok, because the width of each characters is different. Could you please help me to give a more optimized way?

问题 I currently have an Angular Directive that validates a password and confirm password field as matching. It works to a point, it does throw an error when the passwords do not match. However, it doesn't throw the error until you have entered data in both fields. How can I make it so the error for mismatched passwords is thrown as soon as you enter data in one field or the other? Here is the directive (it has to be added to both fields that need to match): .directive('passwordVerify', function()

问题 I have a multiple sets of two divs and a button for each per page. The two divs contains alternating content that the button should handle switching visibility. I can't seem to think of an Angular solution that can be extensible to multiple separate instances in the page (my mind keeps wanting to get it done in JQuery). I have created a JSFiddle example here. You will see two divs p_table class with <span class="trigger">A</span> . The trigger should alternate the two p_table inside their

问题 I need to build a dialog to be used with any item on a list of items. The dialog is pretty much the same regardless of the item except for the values of the fields which are obviously item dependent. The directive I am building is reading the template from a file, compiles it with $compile and then binds (links) it to the scope of the item. The result of the binding is a DOM tree. To make the dialog visible I need to append this tree to some element in the existing DOM. The nature of my

问题 I'm writing a directive which creates an mp3/audio player. The issue is that you can have many audio players in one page. What I would like to do is when one is playing and you start an other, that the one currently playing pauses. How can I achieve this with angular directives?

The one thing that you

问题 I m trying to use footable(http://themergency.com/footable-demo/responsive-container.htm) along with angular.js.
