Implementing Click Event to Dynamically Created div using jQuery

I have recently started using JQuery and I am encountering difficulties in binding functions to a dynamically created div.

When the user clicks on a button, new divs are added to a container along with a change in the background color of that container. Users should also have the option to remove the added content by clicking on one of the divs.

I tried implementing this function:

$('.course-delete').click(function() {
    var course = $(this).parent();
    alert("hello");
    $(course).css('background', "#fff");
    $(course).empty();  
});

However, when I click on the div, nothing seems to happen. Any insights into what might be causing this would be greatly appreciated.

It seems like your .course-delete elements are not present when jQuery tries to attach the event handler because these divs are generated dynamically at a later time. In such cases, event delegation comes to the rescue: https://learn.jquery.com/events/event-delegation/

$(document).on('click', '.course-delete', function () {
    /* perform deletion operation here */
});

Improve performance by delegating the click event to the closest container.

$("#divcontainer").on("click", ".course-delete", function() {

});

If you're looking to add a new div element dynamically, you can follow these steps:

//Create a new DIV element
var newDiv = $('<div />', {
    html: 'This is some sample HTML content', // Add your own HTML content here
    click: function() {
        // Your click event handler code goes here
    }
});

Then, you can append this new element to the document using the following code:

newDiv.appendTo('body'); // You can replace 'body' with any selector where you want to append the new element. Use prependTo if you want it as the first child of the container.

Putting it all together, you can achieve this result:

$('<div />', { // Set attributes and other properties for the new div element here
    html: 'This is some sample HTML content', // Add your HTML content
    click: function() {
        // Event handler for click event
    }
 }).appendTo(container);
