這是一款基于HTML5的焦點(diǎn)圖動(dòng)畫，它和其他焦點(diǎn)圖不同的地方在于，它播放的不僅僅是圖片，而是可以自定義控制的網(wǎng)頁(yè)元素。它不僅在圖片間切換有過(guò)渡動(dòng)畫效果，而且在切換時(shí)圖片中的元素也將出現(xiàn)動(dòng)畫效果，比如圖中的文字移動(dòng)、打散、重新組合等。這款HTML5動(dòng)畫圖片播放器算得上是高端大氣上檔次。

tlrkSlider

  example usage:

    $("#slider").tlrkSlider({
      autoStart: false,
      elements: {
        "img": {delay: 10},
        "h2": {delay: 500},
        ".copy": {delay: 800},
        ".button": {delay: 1000}
      }
    });

  to go to a specific frame:
    $("#slider").tlrkSlider("go", position);
    "position" can have one of the following values:
    "next", "prev", "first", "last", "+1", "-1" or a numeric value

  to start/stop the automatic loop:
    $("#slider").tlrkSlider("start");
    $("#slider").tlrkSlider("stop");

  to change the delay between automatic transitions:
    $("#slider").tlrkSlider("option", "delayAnimation", 1000);

  to change any option:
    $("#slider").tlrkSlider("option", option_name, option_value);

  Changing the "elements" object is not tested.

  Changing the following options: "navigation", "navigationClass", "framesSelector", "autoStart" won&#39;t have any effect for now.
  They are used only during the initialization.

  $("#slider").data("tlrkSlider") will return the plugin instance and the methods/properties can be accessed from there.

  The plugin contructor defaults are accessable through TlrkSlider.defaults

  The function that actually sweep the elements in/out can be overriden from
    TlrkSlider.prototype._animationIn and TlrkSlider.prototype._animationOut

    See sweepIn/sweepOut
