/**
 * creates a carousel-style navigation widget for images/any-content from a simple html markup.
 *
 * the html markup that is used to build the carousel can be as simple as...
 *
 *  <div class="carousel">
 *      <ul>
 *          <li><img src="image/1.jpg" alt="1"></li>
 *          <li><img src="image/2.jpg" alt="2"></li>
 *          <li><img src="image/3.jpg" alt="3"></li>
 *      </ul>
 *  </div>
 *
 * as you can see, this snippet is nothing but a simple div containing an unordered list of images.
 * you don't need any special "class" attribute, or a special "css" file for this plugin.
 * i am using a class attribute just for the sake of explanation here.
 *
 * to navigate the elements of the carousel, you need some kind of navigation buttons.
 * for example, you will need a "previous" button to go backward, and a "next" button to go forward.
 * this need not be part of the carousel "div" itself. it can be any element in your page.
 * lets assume that the following elements in your document can be used as next, and prev buttons...
 *
 * <button class="prev"><<</button>
 * <button class="next">>></button>
 *
 * now, all you need to do is call the carousel component on the div element that represents it, and pass in the
 * navigation buttons as options.
 *
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev"
 * });
 *
 * that's it, you would have now converted your raw div, into a magnificient carousel.
 *
 * there are quite a few other options that you can use to customize it though.
 * each will be explained with an example below.
 *
 * @param an options object - you can specify all the options shown below as an options object param.
 *
 * @option btnprev, btnnext : string - no defaults
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev"
 * });
 * @desc creates a basic carousel. clicking "btnprev" navigates backwards and "btnnext" navigates forward.
 *
 * @option btngo - array - no defaults
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      btngo: [".0", ".1", ".2"]
 * });
 * @desc if you don't want next and previous buttons for navigation, instead you prefer custom navigation based on
 * the item number within the carousel, you can use this option. just supply an array of selectors for each element
 * in the carousel. the index of the array represents the index of the element. what i mean is, if the
 * first element in the array is ".0", it means that when the element represented by ".0" is clicked, the carousel
 * will slide to the first element and so on and so forth. this feature is very powerful. for example, i made a tabbed
 * interface out of it by making my navigation elements styled like tabs in css. as the carousel is capable of holding
 * any content, not just images, you can have a very simple tabbed navigation in minutes without using any other plugin.
 * the best part is that, the tab will "slide" based on the provided effect. :-)
 *
 * @option mousewheel : boolean - default is false
 * @example
 * $(".carousel").xyscroll({
 *      mousewheel: true
 * });
 * @desc the carousel can also be navigated using the mouse wheel interface of a scroll mouse instead of using buttons.
 * to get this feature working, you have to do 2 things. first, you have to include the mouse-wheel plugin from brandon.
 * second, you will have to set the option "mousewheel" to true. that's it, now you will be able to navigate your carousel
 * using the mouse wheel. using buttons and mousewheel or not mutually exclusive. you can still have buttons for navigation
 * as well. they complement each other. to use both together, just supply the options required for both as shown below.
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      mousewheel: true
 * });
 *
 * @option auto : number - default is null, meaning autoscroll is disabled by default
 * @example
 * $(".carousel").xyscroll({
 *      auto: 800,
 *      speed: 500
 * });
 * @desc you can make your carousel auto-navigate itself by specfying a millisecond value in this option.
 * the value you specify is the amount of time between 2 slides. the default is null, and that disables auto scrolling.
 * specify this value and magically your carousel will start auto scrolling.
 *
 * @option speed : number - 200 is default
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      speed: 800
 * });
 * @desc specifying a speed will slow-down or speed-up the sliding speed of your carousel. try it out with
 * different speeds like 800, 600, 1500 etc. providing 0, will remove the slide effect.
 *
 * @option easing : string - no easing effects by default.
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      easing: "bounceout"
 * });
 * @desc you can specify any easing effect. note: you need easing plugin for that. once specified,
 * the carousel will slide based on the provided easing effect.
 *
 * @option vertical : boolean - default is false
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      vertical: true
 * });
 * @desc determines the direction of the carousel. true, means the carousel will display vertically. the next and
 * prev buttons will slide the items vertically as well. the default is false, which means that the carousel will
 * display horizontally. the next and prev items will slide the items from left-right in this case.
 *
 * @option circular : boolean - default is true
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      circular: false
 * });
 * @desc setting it to true enables circular navigation. this means, if you click "next" after you reach the last
 * element, you will automatically slide to the first element and vice versa. if you set circular to false, then
 * if you click on the "next" button after you reach the last element, you will stay in the last element itself
 * and similarly for "previous" button and first element.
 *
 * @option visible : number - default is 3
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      visible: 4
 * });
 * @desc this specifies the number of items visible at all times within the carousel. the default is 3.
 * you are even free to experiment with real numbers. eg: "3.5" will have 3 items fully visible and the
 * last item half visible. this gives you the effect of showing the user that there are more images to the right.
 *
 * @option start : number - default is 0
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      start: 2
 * });
 * @desc you can specify from which item the carousel should start. remember, the first item in the carousel
 * has a start of 0, and so on.
 *
 * @option scrool : number - default is 1
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      scroll: 2
 * });
 * @desc the number of items that should scroll/slide when you click the next/prev navigation buttons. by
 * default, only one item is scrolled, but you may set it to any number. eg: setting it to "2" will scroll
 * 2 items when you click the next or previous buttons.
 *
 * @option beforestart, afterend : function - callbacks
 * @example
 * $(".carousel").xyscroll({
 *      btnnext: ".next",
 *      btnprev: ".prev",
 *      beforestart: function(a) {
 *          alert("before animation starts:" + a);
 *      },
 *      afterend: function(a) {
 *          alert("after animation ends:" + a);
 *      }
 * });
 * @desc if you wanted to do some logic in your page before the slide starts and after the slide ends, you can
 * register these 2 callbacks. the functions will be passed an argument that represents an array of elements that
 * are visible at the time of callback.

/**
 * 可多次调用，执行最后一次。
 * 使用方法：
 * 在表单中需要验证的内容上添加如下内容：
 * xy-check="true"  必填验证，为true时必填，否则选填。
 * xy-empty="aa"  配合必填验证使用，当验证内容等于参数值时，等同于值为空。
 * xy-check-type="tel"  验证类型，可选；如必填验证为true时先验证必填项再验证类别，如必填验证为false或为空时当有值时才验证类别。
 * 当xy-check-type的值为func时，可执行在提交表单时需要执行的方法或ajax。
 * xy-func="test()"  可执行的方法名称，不带参数，return返回值为true或false，如要运行ajax可将内容写在方法内，return返回值必须放在ajax外面。
 * xy-msg=""  错误提示语句，当运行如xy-check-type="func"时，由于无法确定需要提示什么错误信息，可通过此参数传入，注意没有中英文之分。
 *
 * placeholder=""  验证提示信息对应表单名称，必需，当通过jquery增减表单内容时可用其他内容替换，但在jquery代码中必须为其赋值。
 *
 * min="7"  位数必须大于7，可选。
 * max="12"  位数必须小于12，可选。
 * min和max可同时使用，也可只使用其中之一，或两个都不使用。
 *
 * different="true"  验证当不为空时a、b项必须不同，单个时验证不起作用，多个时第一个分别与其他内容进行比较，一般用于用户名与密码的设置。
 * identical="true"  与different类似，验证当不为空时a、b项必须相同，一般用于密码与确认密码时。
 *
 * 当input的type为file时，参数multiple表示可以上传多张图片；参数max="1"指文件大小，可为小数，单位mb；参数xy-check-type="jpg,doc,docx,xlsx"可以上传的文件类型，基本的格式都已存在。当浏览器不支持html5时，普通的file组件只能上传一张图片，且无法验证文件大小。
 * 当input的type为radio或checkbox，且必填验证为true时，验证是否选择选项，同一选项组只需为一个选项添加必填验证功能，添加位置根据实际情况而定，一行添加到最后一项，多行添加到第一行最后一项。
 * checkbox有min和max参数可供增加。
 * 当select中有参数multiple时，表示可以多选，这时可以添加min和max
 *
 * 当提交确认按钮处有xy-check-request="true"参数时，表示表单中有多个相同name的文本域或文本框，并且有要求必须填写一项，按钮处的参数xy-msg=""为此时错误提示语句。
 *** 目前暂时做到一张表单中没有其他需要验证的表单内容，今后发展方向：将name作为参数传值过来再处理参数。
 *
 * 错误标志显示说明：
 * 当父标签有类名append时，在父标签结尾处插入错误标志；
 * 当父标签没有上述类别时，默认在该表单项之后插入错误标志。
 * 当父标签有类名top时，在该表单项加类名top，效果是错误标志垂直顶部对齐。
