How Can I Simulate User Text Input in JavaScript and jQuery?

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);
});
