How can you retrieve an element by its ID using AngularJS?
The given code snippet demonstrates how to use AngularJS to get an element by its ID and change its color. It begins by defining an AngularJS application and a controller. Inside the controller, there is a function called changeColor(). When a button is clicked, this function is triggered.
Within the changeColor() function, the desired element is obtained using the angular.element method in combination with document.querySelector, passing in the ID of the element as the selector. The obtained element is then manipulated by setting its CSS color property to "red" using the element.css() method.
In summary, the code uses AngularJS to retrieve an element with the specified ID and modify its color to red when the button is clicked.
