Bind an externally loaded DOM element to Angular's scope

阅读更多关于 Bind an externally loaded DOM element to Angular's scope

I'm using Google Maps within an Angular app. As per Google Maps's API, I pass a string to a google.maps function containing HTML, and the library displays it on the map as an InfoView. I'm adding a button to this view, and I want this view to be bound to a controller in my Angular app, however, even if I pass <div ng-controller="MyController">...</div> , when the Maps library attaches it to the DOM, Angular is not notified. How can I force the compilation of this element (over which I have very little control: just passing a string)? For AngularJS to "notice" the directive, it'd need to

Pass variable to UI-bootstrap modal without using $scope

阅读更多关于 Pass variable to UI-bootstrap modal without using $scope

Since I am a beginner using AngularJS the $scope approach to pass data between different controllers and (in my case) a modal drives me crazy. Due to that reason, I googled around the web and found an interesting blogpost about passing data to a UI-bootstrap modal without using $scope . I had a deeper look at this blogpost and the delivered plunk which works pretty nice and started to adopt this to my own needs. What I want to achieve is to open a modal delivering an text input in which the user is able to change the description of a given product. Since this would provide more than a minimal

angularjs form can not refer to input control when input name is array

阅读更多关于 angularjs form can not refer to input control when input name is array

问题 I encounter a problem when testing form validation with angularjs According to angularjs form guide, an input control that has the ngModel directive holds an instance of NgModelController. Such a control instance can be published as a property of the form instance using the name attribute on the input control. I created test code at plunker, it all works fine untill I change the input name from <input type="number" name="age" ng-model="user.age" max="100" required> <p>{{form1.age.$error}}</p>

I have slightly modified the example from the following URL ( http://docs.angularjs.org/cookbook/helloworld ) as follows, placing the name value within an attrs object property: <!doctype html> <html ng-app> <head> <script src="http://code.angularjs.org/1.2.9/angular.min.js"></script> <script> function HelloCntl($scope) { $scope.attrs = { name : 'World' } } </script> </head> <body> <div ng-controller="HelloCntl"> Your name: <input type="text" ng-model="attrs.name"/> <hr/> Hello {{attrs.name || "World"}}! </div> </body> </html> One benefit I can see is that the HTML source code can be searched

How to load dynamic inline template with angular

I have an ng-repeat that loops over an array of objects. At each loop the value 'template' & 'values' is initialised. The following version works and uses ng-include to load the template but it happens to be very very slow: <tr class="tableRowsDocs" ng-repeat="dbo in rows track by $index"> <div ng-init="values = dbo.get4(attobj.key); key = attobj.key; template = attobj.template || getAttributeTemplate(dbo.clazz + attobj.key);"> <div class="content" ng-include="template"></div> </div> </td> </tr> The value for template and values is dynamic but it always holds the id of a template/script like:

angular extend $scope is it safe?

阅读更多关于 angular extend $scope is it safe?

问题 This thread follow angularjs share data config between controllers so I'm wondering if instead of copy by hand property/method is it safe doing like .factory('MyTest',function(){ return { prop: 'Mytest', myFunc: function(){ alert('Hello'); } } }) .controller('IndexCtrl', function ($scope,MyTest) { angular.extend($scope,MyTest); console.log($scope); }) Update It works of course only for property but if it's safe could be a good thing find a way to apply it also for method. UPDATE 1 This seems

AngularJS : How to transclude and have both isolate scope and parent scope?

阅读更多关于 AngularJS : How to transclude and have both isolate scope and parent scope?

I have a pattern wherein many item types are "editable". This means that I have lots of templates (one for each editable item type) that expect to have unique fields, but common functions (edit, save, cancel edit, delete, etc.). These common functions lead to lots of repetition on controllers: save , edit , cancel , etc., and very repetitive error-handling. One way I looked at of dealing with this was to have each controller "decorate" itself (using a service), but it got messy as well. I prefer a directive, say, 'editable': <form name="editGroup" editable> <div ng-show="editMode"> <!-- lots
