Emulating User Text Input with JS and jQuery
To simulate user input within a text input box, you can utilize direct event triggering. Each relevant event in the input process can be triggered individually, such as:
- focus()
- keydown()
- keypress()
- keyup()
- blur()
- change()
To trigger these events, simply use the following syntax:
$(function() {
$('item').focus();
$('item').keydown();
$('item').keypress();
$('item').keyup();
$('item').blur();
});
In case you want to trigger specific characters with the key-events, you can use the following code:
$(function() {
var e = $.Event('keypress');
e.which = 65; // Character 'A'
$('item').trigger(e);
});

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
