What is the reason behind the image not displaying before the AJAX request is initiated and then disappearing once the request is completed?

Question

What is the reason behind the image not displaying before the AJAX request is initiated and then disappearing once the request is completed?

I am attempting to display a "loading" gif while my AJAX request is being processed. Below are the functions I am using:

beforeSend: function () { 
   $('.form-sending-gif').show(); 
   console.log("The beforeSend function was called"); 
}

and

complete: function () { 
   $('.form-sending-gif').hide(); 
   console.log("The complete function was called"); 
}

The console.log statements are for testing purposes. Despite confirming that both functions are running, the image is not displaying or hiding as expected. I have checked with $('.form-sending-gif').show() in the console and it works correctly. The image is supposed to be shown on page load.

What could be the issue here?

Without more specific details provided in your question, it's a bit challenging to provide an accurate answer. However, I will give it a shot.

One potential solution could involve implementing the following code snippet:

$(function () {

    // Click event function
    $('#test').click(function(){
        // Display loading image here
        $('#test').text('Greetings')

        // Simulated ajax request(put your ajax here)
        var ajaxCallDfd = $.Deferred();
        setTimeout(function () {
            ajaxCallDfd.resolve();
        }, 1000);

        // Once the ajax call is complete, display the loaded image
        $.when(ajaxCallDfd).then(function(){
            $('#test').text('Goodbye')
        })
    });
});
