I am facing an issue where I need to retrieve something in a directive
and then set it in the HTML code.
How can I accomplish setting something in HTML and getting it in a directive?
Here is the HTML code snippet:
<div my-directive="Bob">
<div>
And here is the corresponding directive.js file:
App.directive('myDirective', function () {
link: function () {
console.log('xxx')
}
})
Now, the question remains - How can I access the value 'Bob' within the directive?
Absolutely, by utilizing attrs
link: function (scope, element, attrs) {
console.log(attrs.myDirective); // Prints out Alice
}
The attrs variable stores key-value pairs with keys representing the standardized attribute names of elements and values containing the individual string values of each attribute.
Absolutely, you have the ability to utilize params in a directive.
Here is a solution for one-way data binding
controller:
$scope.options = {one: "first, two: "second"};
view:
<div databinding="options"></div>
Additionally, in the javascript:
app.directive('databinding', function () {
return{
scope: {
options: "@" //You can also use = here
},
link: function (scope, elm, attrs) {
console.log(scope.options);
}
}
});
