Like how the click() can be used to trigger a click event on an element, is there any way to simulate the typing of a string?

    If you really want to simulate typing (i.e. including triggering the events and appending the text to an input or textarea element), you can use the jQuery simulate extended plugin:
    http://j-ulrich.github.com/jquery-simulate-ext

    Then you can use

    $('input').simulate("key-sequence", {sequence: "This is a test", delay: 10});
    

    to simulate the typing of the text "This is a test" with a 10ms delay between each key press.

    Disclaimer: I'm the author of the plugin.

    Are you looking for a way to trigger the events associated with typing or do you want to append text to a container so that it looks like someone is typing? If you're looking for the events, then @Nick is absolutely correct in suggesting the methods for triggering the event. If the latter, you'll want to use a timer to replace the text/html of the container with successive substrings of your text. You might be able to get a better effect by appending successive span elements containing each letter if the text is very long -- this would reduce flashing as the text gets replaced and the layout changes momentarily.

    EDIT: I was going to add an example, but it turns out there's a plugin for that already: jTypeWriter.

    You can use these events, depending on what you want:

    • .keydown()
    • .keypress()
    • .keyup()
