DIV CSS 佈局教程網

這是一款基於HTML5的焦點圖動畫，它和其他焦點圖不同的地方在於，它播放的不僅僅是圖片，而是可以自定義控制的網頁元素。它不僅在圖片間切換有過渡動畫效果，而且在切換時圖片中的元素也將出現動畫效果，比如圖中的文字移動、打散、重新組合等，這款HTML5動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'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

   if (typeof otherArgs[0] === "object") { // extend the config with new options
   pluginData.config = $.extend(pluginData.config, otherArgs[0]);
   }

  } else { // call a method?
   try {
   pluginData[options].apply(pluginData, otherArgs);
   } catch(ex) {
   throw "Error calling a plugin method (" + ex + ")";
   }
  }
  }
 });
 };

 window.TlrkSlider = TlrkSlider;

})( jQuery, window , document );

下面是頁面調用的JS代碼：

$(document).ready(function(){
 var $backgrounds = $(".header-content").find(".parallax-bg"),
  LAYER_OFFSET = 30,
  PRLX_SPEED = 1500,
  $slider;

 $slider = $("#slider").tlrkSlider({
 autoStart: true,
 animationStart: function(ev, slider, step){
  var max_steps = this.framesCount; 
  $backgrounds.each(function(idx, el){
  var pos = (step * (100 / max_steps)) + (LAYER_OFFSET * idx);
  $(this).animate({"backgroundPosition": pos + "% 0"}, PRLX_SPEED);
  });
 },
 elements: {
  "img": {delay: 10},
  "h2": {delay: 500},
  ".copy": {delay: 800},
  ".button": {delay: 1000}
 }
 });

 $(".header-content")
 .hover(
  function(){$(this).find(".slider-prev, .slider-next").show();},
  function(){$(this).find(".slider-prev, .slider-next").hide();}
 )
 .find(".slider-prev").click(function(){$slider.tlrkSlider("go", "prev"); return false; }).end()
 .find(".slider-next").click(function(){$slider.tlrkSlider("go", "next"); return false; });

});
