Let's say I have a directive called "foo" with the following content:
<div>
<label>Enter foo: </label>
<input ng-model="myModel"/>
</div>
Then, I use it in the following way:
<foo></foo>
<button>Add foo: </button>
My goal is to dynamically add the "foo" directive every time the button is clicked and access the new model variable created in the controller of this page.
Is it possible to achieve this using angularJS?
To begin with, if you intend to reuse the <foo> element, it's advisable to establish an isolated scope:
.directive("foo", function(){
return {
restrict: "E",
scope: {
data: "="
},
template: "<div><label>Enter foo: </label><input ng-model='data'/></div>"
}
});
Creating a custom directive is similar to defining other tags. Given the limited context provided, here is a suggestion:
app.controller("MainCtrl", function($scope)){
$scope.fooModels = [];
$scope.addFoo = function(){
$scope.fooModels.push(new FooModel());
};
}
The FooModel() function serves as a placeholder for the desired foo data model. Alternatively, you can simply use $scope.fooModels.push({});.
Subsequently, in the view, use ng-repeat to iterate through your fooModels:
<div ng-repeat="fooModel in fooModels">
<foo data="fooModel.data"></foo>
</div>
<button ng-click="addFoo()">Add Foo</button>
Feel free to explore and experiment with this concept in a plunker.
