The color type input is not responding to the onChange event

Question

The color type input is not responding to the onChange event

I have been searching a lot and exploring answers on Stack Overflow, yet I have had no luck. I am trying to retrieve the color value when the color is changed in an input field.

Here is the code I am using, could you please assist me in finding out why it's not functioning?

 <input type="color" id="bgcolor" value="#ffffff" onchange="test()" />

Below is the JavaScript code snippet:

 function test(){
    console.log('working.....'); 
 }

This function seems to be malfunctioning. Interestingly, when I replace onChange with onclick, it works perfectly. However, I am eager to understand why it does not work with onChange?

Encountering the same issue with Chrome and Firefox on Windows, I have noticed that it only happens with pure black, pure white, or any color very close to them.

Upon observing the Color picker, it becomes apparent that the RGB values remain unchanged when moving the cursor in the main square (they only change when using the vertical slider on the right, which the average user may not be inclined to do).

Similar behavior is witnessed in other applications that utilize the same color picker, such as MSpaint or Tkinter's tkColorChooser.askcolor(). Presumably, this is the default color picker in Windows, as indicated by the British English spelling of "colour" being my default language choice.

To resolve this issue, simply avoid using colors that are #ffffff or #000000 (or colors very close to them) as your starting color.

<label for="doesntWork1">doesn't work</label> <input type="color" id="doesntWork1" value="#ffffff" onchange="alert(this.value);" />
<p>
<label for="doesntWork2">doesn't work</label> <input type="color" id="doesntWork2" value="#000000" onchange="alert(this.value);" />
<p>
<label for="works1">works</label> <input type="color" id="works1" value="#fdffff" onchange="alert(this.value);" />
<p>
<label for="works2">works</label> <input type="color" id="works2" value="#000002" onchange="alert(this.value);" />

The issue that some individuals are encountering with inconsistent behavior in various browsers arises from the use of the onchange event (change in jQuery), which is not the suitable event for color inputs (thus leading to sporadic success or failure, particularly on Mac OS X).

To resolve this, it is recommended to utilize oninput (or input when employing jQuery), as this event operates smoothly across all browsers and platforms.

$('#bgcolor').on('input',
    function() {
        console.log($(this).val());
    }
);

During my latest Angular project (version 13), I implemented the following code snippet using (input)="":

<input
    (input)="someFunction()"
    type="color" />

This feature enables the continuous execution of the function someFunction() in real-time as the user selects colors from a gradient interface.
