  • 0

I have INPUT element and I want to reset the previous value (not necessary original value). There are 2 ways:

  1. Save the value in another variable and pull it out again
  2. Press ESC key. But I don’t want users to press ESC but click a button.

So for #2, how can I create a ESC keystroke using jquery?

    Here’s an SSCCE:

    <!doctype html>
<html lang="en">
    <head>
        <title>SO question 2079185</title>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function() {
                $(':input.remember').each(function() {
                    $(this).attr('data-remember', $(this).val());
                });
                $('button.reset').click(function() {
                    $(':input.remember').each(function() {
                        $(this).val($(this).attr('data-remember'));
                    });
                });
            });
        </script>
    </head>
    <body>
        <input type="text" class="remember" value="foo">
        <button class="reset">Reset</button>
    </body>
</html>

    This basically stores the original value of every input element with a class of remember during onload and instructs the button with a class of reset to restore it whenever clicked.
