Acquire user input using AngularJS

Is it possible to retrieve the value of an input text using AngularJS without utilizing a Controller? If so, what approach would achieve this? I have come across some resources discussing similar queries, but they all involve .controller here is one such post

Answer №1

Below are two ways to access the value of an input tag using AngularJS and jQuery:

Using AngularJS:
angular.element(document.querySelector('#your_input_tag_id')).val();

Alternatively, you can also achieve the same result with jQuery:

$('#your_input_tag_id').val();

Answer №2

Transform your input into a model to ensure the value is always accessible within the model

<input type="text" ng-model="myModelName">

This allows you to easily access the value using myModelName within the scope of your module

console.log('value = ' + $scope.myModelName);

If you find yourself trying to retrieve the value from outside the scope of the module or app, it may not align with Angular's principles. It is recommended to utilize a controller or link function, even if it's the main one. If instructed otherwise, consider questioning that requirement (which could be misguided).

Answer №3

Instead of searching the DOM for elements (which may not align well with AngularJS principles - see How do I "think in AngularJS" if I have a jQuery background?), it is recommended to handle your DOM manipulation within your directive. The element is readily available to you in the link function.

For instance, in your myDirective:

return {
    link: function (scope, element, attr) {
        element.html('Hello world');
    }
}

If you really need to perform the query outside of the directive, one option would be to use querySelectorAll in modern browsers:

angular.element(document.querySelectorAll("[my-directive]"));
$('#your_input_tag_id').val();

However, keep in mind that jquery will be required to support IE8 and earlier versions:

angular.element($("[my-directive]"));
