Is it possible to transfer $scope.data to a directive through its attribute in an Object, without using separate attributes? I would like to achieve the below format with any solution.
<custom-directive detail="{index:1, data: {{data}}}">
</custom-directive>
The scope in the directive is configured as shown below:
scope: {detail: "="}
One possible solution:
return {
restrict: 'E',
require: 'ngModel',
scope: {
model: '=ngModel',
},
link: function(scope, element, attributes, ngModel) {
if (!ngModel) {
return;
}
console.log(scope.model); // data passed to directive
}
}
Then,
<custom-directive ngModel="data"></custom-directive>
Now, your $scope.data will be accessible as scope.model inside the directive. Keep in mind that any changes made to scope.model within the directive will also affect $scope.data.
To prevent this, you can simply modify the ngModel:
return {
restrict: 'E',
scope: {
data: '=myData',
},
link: function(scope, element, attributes) {
console.log(scope.data); // data passed to directive
}
}
And then,
<custom-directive my-data="data"></custom-directive>
When writing data in your object, it will automatically be resolved from your controller. Follow the steps below:
HTML
<custom-component info="{value:1, content: data}">
</custom-component>
Component
myApp.component('customComponent', {
bindings: {
info: "="
},
controller: function() {
alert(JSON.stringify(this.info));
}
});
One important step remains for you to complete the establishment of your entity within the controller:
$scope.entry = {id:1, information:$scope.information};
Afterwards, pass it along to the custom directive by using this syntax:
<custom-directive entry="entry"></custom-directive>
