Guide to using the ng-click function in Angular to set focus on the input in the last row of a table

I am in the process of developing a task management application and I am looking to implement a specific feature:

Upon clicking 'Add Task', a new row is automatically added to the table (this part has been completed) and the input field within the latest table row becomes focused.

However, I do not want the input field to be automatically focused when the page loads; instead, I only want it to focus when a button with ng-click is clicked. Unfortunately, I am unsure of how to achieve this. Can anyone provide assistance? Would using $broadcast and $on functions be helpful in this scenario?

Thank you in advance for your help.

Answer №1

I am not quite sure about the process of adding a new row to a table in Angular. Being new to Angular, I am uncertain of a method that will effectively work with ng-click. It is advised against manipulating the DOM directly in the controller, so my suggestion would be to create a custom directive specifically for the 'Add Task' button. Within this directive, you can include a click listener in the link function for the element, which will then add a new row to the table and focus on the input element within it. An example of how this could be implemented is shown below:

.directive('myDir', function () {
    return {
         restrict: 'A',
         scope: true,
         link: function (scope, element, attrs) {

            function functionToBeCalled () {
                console.log("Success!");
            }

            element.on('click', functionToBeCalled);
        }
    };
});

You are free to insert your own DOM manipulation code within the functionToBeCalled function. Please note that this code serves as a basic reference to help illustrate the concept.

Due to lack of motivation, I shamelessly borrowed the directive code from this response.
