Dynamically adding Angular directives

阅读更多关于 Dynamically adding Angular directives

I'm fairly new to angular JS and am finding it a steep learning curve, I get the feeling im really missing the point here but here goes: I want to add a directive to my page from a controller. So I thought if I add the directive tag to the page, the directive and associated controller/template etc get added with it. After reading about the $compile method, I thought this would then be used to bind this directive to its newly created tag. This part is commented out below, but with or without this, I need the word login to appear and its controller to control it? I can find lots of examples of

Angular: How to force recompile directive?

阅读更多关于 Angular: How to force recompile directive?

HTML: <div ng-repeat="obj in arr"> <custom-directive status-stored-in="obj"></custom-directive> </div> Problem: I have page-turn built in for the large amount of obj s. Which means that the value of arr , representing the current page of obj s, will change. However, the obj in the status-stored-in="obj" part is not refreshed with the change. Right now my solution is to add a ng-if in customDirective , flickering its value back and forth to have it force recompiled. Is there any other equivalent, neater way to deal with this? Edit: The start of the custom directive: module.directive 'checkbox',

阅读更多关于 passing object to angularjs directive from the controller

Trying to get my head around AngularJS directives. I need to pass a full object from my main controller to the directive. See the code below and jsfiddle: http://jsfiddle.net/graphicsxp/Z5MBf/4/ <body ng-app="myApp"> <div ng-controller="MandatCtrl"> <div person myPerson="mandat.person"></div> <span>{{mandat.rum}}</span> <span>{{mandat.person.firstname}}</span> </div> and the script: var myApp = angular.module("myApp", []); myApp.controller("MandatCtrl", function ($scope) { $scope.mandat = { rum: "15000", person: { id: 1408, firstname: "sam" } }; }); myApp.directive("person", function () {

Angular.js updating SVG templates in directives

阅读更多关于 Angular.js updating SVG templates in directives

问题 A while ago I asked about "Angular.js rendering SVG templates in directives", where I was replacing the DOM nodes that angular makes when rendering templates, with SVG nodes. I got a response that answered it for me, but I realized that I lost all the databindings from angular. See Plunkr (click update): http://plnkr.co/edit/HjOpqc?p=preview How do I replace these DOM nodes with SVG nodes, and leave my angular bindings intact? I tried using $compile to make it work (as I've done with regular

Angularjs currency format in input box with ng-model: how to get $formatters to fire on each input

阅读更多关于 Angularjs currency format in input box with ng-model: how to get $formatters to fire on each input

I have searched everywhere for this. Every stack overflow that has an answer, it does not actually work. Same with any examples or google group examples from for angular including the docs. Seems simple. I want a function to get called on an input for each key pressed by the user. simple input with a ng-model <input class="form-control" ng-model="model.thisisnotfun" formatter type="text" required> According to everything i read. $formatters should update the value from the model to the view calling any functions in the $formatters array. They never get called when i type in the input box.

Passing a binding to transcluded scope in component

阅读更多关于 Passing a binding to transcluded scope in component

In AngularJS 1.5, I want to pass a binding from a component into the (multi-slot) transcluded scope - for a reference in the template (in either one specific or all of them - no either way is fine). This is for creating a generic custom-select list // Component .component('mySelect', { bind: { collection: '<' }, transclude:{ header: 'mySelectHeader', item: 'mySelectItem' }, templateUrl: 'my-select-template', controller: function(){ ..... } }); ... // Component template <script id="my-select-template" type="text/ng-template"> <ol> <li ng-transclude="header"> </li> <li ng-transclude="item" ng

AngularJS directive - setting order for multiple directive elements (not priority for directives, but priority for the elements)

阅读更多关于 AngularJS directive - setting order for multiple directive elements (not priority for directives, but priority for the elements)

问题 Considering this markup with a directive "foo": <div foo run="3"></div> <div foo run="1"></div> <div foo run="2"></div> What is a good approach for causing "foo" to run in the specified order rather than from top to bottom (3,1,2)? The only thing I can think to do would be tracking what has run and returning false on the items that are not in order, then making angular try to run them all again and repeat until they are all done. That sounds terrible to me though, because it would have to

List registered custom directives in AngularJS

阅读更多关于 List registered custom directives in AngularJS

问题 I am writing a web app with many custom directives. Is there a way to view all the directives that have been registered for each module? 回答1: Modules have an _invokeQueue, which contains the contents of the module. A function like this: function Directives(module) { var directives = []; var invokes = angular.module(module)._invokeQueue; for (var i in invokes) { if (invokes[i][1] === "directive") directives.push(invokes[i][2]); } return directives; } will run through the module and grab each
