JarCastingangular-recursion
A service which makes it easy possible to have recursive Angular directives.
Why
When an Angular directive calls itself, Angular gets into an endless loop. This service provides the logic needed to work around this.
Installation
bower install angular-recursion --saveornpm install angular-recursion --save.- Include
angular-recursion.min.js. - Add the
RecursionHelpermodule as a dependency. - Inject the
RecursionHelperservice and use it.
Usage
Inject the RecursionHelper service into your directive, and use it in the compile function, as shown in the example below. The example is also available as a Plunker, so you can see it running.
angular.module('myModule', ['RecursionHelper']).directive("tree", function(RecursionHelper) {
return {
restrict: "E",
scope: {family: '='},
template:
'<p>{{ family.name }}{{test }}</p>'+
'<ul>' +
'<li ng-repeat="child in family.children">' +
'<tree family="child"></tree>' +
'</li>' +
'</ul>',
compile: function(element) {
return RecursionHelper.compile(element, function(scope, iElement, iAttrs, controller, transcludeFn){
// Define your normal link function here.
// Alternative: instead of passing a function,
// you can also pass an object with
// a 'pre'- and 'post'-link function.
});
}
};
});
