A re-introduction to JavaScript - MDC

  • It's useful to start with an idea of the language's history. JavaScript was created in 1995 by Brendan Eich, an engineer at Netscape, and first released with Netscape 2 early in 1996. It was originally going to be called LiveScript, but was renamed in an ill-fated marketing decision to try to capitalise on the popularity of Sun Microsystem's Java language — despite the two having very little in common. This has been a source of confusion ever since.

Javascript - Event order

  • When you use event capturing



                   | |
    ---------------| |-----------------
    | element1     | |                |
    |   -----------| |-----------     |
    |   |element2  \ /          |     |
    |   -------------------------     |
    |        Event CAPTURING          |
    -----------------------------------


    the event handler of element1 fires first, the event handler of element2 fires last.




    Event bubbling



    When you use event bubbling



                   / \
    ---------------| |-----------------
    | element1     | |                |
    |   -----------| |-----------     |
    |   |element2  | |          |     |
    |   -------------------------     |
    |        Event BUBBLING           |
    -----------------------------------


    the event handler of element2 fires first, the event handler of element1 fires last.

  • addEventListener()
    method explained on the Advanced models page.

    false the event handler is set for the bubbling phase.
