Prev&Next按钮带有使用jQuery覆盖的计数器

Question

我使用jquerytools构建这个图像库,我在拇指上使用可滚动的div并在主图像上叠加......一切都像魅力一样......

编辑:在我把它作为赏金之前......我必须解释一下我需要一些干净简单的东西,因为图像来自php(加密),我不能修改它,只是"视图"就像我一样需要通过类和ID来实现这一点.这就是为什么我尝试这个但是...

问题是我需要在查看叠加层时插入下一个和上一个按钮...这样,一旦加载了叠加层,您就可以通过图像进行处理.

我为你做了这个小提琴我的老师充满智慧可以看到我在说什么.http://jsfiddle.net/s6TGs/5/

我真的试过了.但是api.next()它正在用于滚动拇指,所以我不知道怎么能告诉这个脚本..嘿,如果下一个被点击,你可以在thubs上插入下一个url,如果点击上一个btn,请转到大拇指上的流行网址..但我不能

同样重要的是,像1/8这样的计数器必须显示= S ...如何以JavaScript的名义执行此操作..

这是我的代码

$(function() {
$(".scrollable").scrollable();

$(".items img").click(function() {
    // see if same thumb is being clicked
    if ($(this).hasClass("active")) { return; }

    // calclulate large image's URL based on the thumbnail URL (flickr specific)
    var url = $(this).attr("src").replace("_t", "");

    // get handle to element that wraps the image and make it semi-transparent
    var wrap = $("#image_wrap").fadeTo("medium", 0.5);
    var wrap2 = $("#mies1");

    // the large image from www.flickr.com
    var img = new Image();

    // call this function after it's loaded
    img.onload = function() {

        // make wrapper fully visible
        wrap.fadeTo("fast", 1);

        // change the image
        wrap.find("img").attr("src", url);
        wrap2.find("img").attr("src", url);

    };

    // begin loading the image from www.flickr.com
    img.src = url;

    // activate item
    $(".items img").removeClass("active");
    $(this).addClass("active");

// when page loads simulate a "click" on the first image
}).filter(":first").click();
});

// This makes the image Overlay with a div and html

  $(document).ready(function() {
      $("img[rel]").overlay({

      // some mask tweaks suitable for modal dialogs
      mask: {
        color: '#ebecff',
        loadSpeed: 200,
        opacity: 0.9
      },

      closeOnClick: true
  });
});

我知道这是我的答案的一部分,我可以让它工作:(

编辑:感谢QuakeDK的第一个答案我几乎达到了目标..但是计数器不行,当你到达4图像(柜台上的数字5)你不能去第5拇指..这是代码随着答案的整合

这是PREV和NEXT BUTTON的代码

//NExt BTN

  $(".nextImg").click(function(){
            // Count all images
            var count = $(".items img").length;

            var next = $(".items").find(".active").next("img");
            if(next.is(":last")){
                next = $(".items").find(".active").parent().next("div").find("img:first");
                if(next.index() == -1){
                    // We have reached the end - start over.
                    next = $(".items img:first");
                    scrollapi.begin(200);
                } else {
                    scrollapi.next(200);
                }
            }

            // Get the current image number
            var current = (next.index("img"));

            var nextUrl = next.attr("src").replace("_t", "");

            // get handle to element that wraps the image and make it semi-transparent
            var wrap = $("#image_wrap").fadeTo("medium", 0.5);
            var wrap2 = $("#mies1");

            // the large image from www.flickr.com
            var img = new Image();

            // call this function after it's loaded
            img.onload = function() {
                // make wrapper fully visible
                wrap.fadeTo("fast", 1);

                // change the image
                wrap.find("img").attr("src", nextUrl);
                wrap2.find("img").attr("src", nextUrl);
            };

            // begin loading the image from www.flickr.com
            img.src = nextUrl;

            $("#imageCounter").html("Image: "+current+" of "+count);

            // activate item
            $(".items img").removeClass("active");
            next.addClass("active");

        });

  //PREV BTN

    $(".prevImg").click(function(){
            // Count all images
            var count = $(".items img").length;

            var prev = $(".items").find(".active").prev("img");
            if(prev.is(":first")){
                prev = $(".items").find(".active").parent().prev("div").find("img:first");
                if(prev.index() == -1){
                    // We have reached the end - start over.
                    prev = $(".items img:first");
                    scrollapi.begin(200);
                } else {
                    scrollapi.prev(200);
                }
            }

            // Get the current image number
            var current = (prev.index("img"));

            var prevUrl = prev.attr("src").replace("_t", "");

            $("#imageCounter").html("Image: "+current+" of "+count);

            // activate item
            $(".items img").removeClass("active");
            prev.addClass("active");    
        });

这里必须有一个奖励选项,如果有人帮助我,我会给你20box!jajaja我很绝望.因为现在我还需要为每个图像显示标题,我认为它与URL替换的过程相同,但是next&prev只是我无法管理的东西..在paypal上发布完整的解决方案和你的电子邮件,我会支付20!

好吧,从未尝试过jQueryTOOLS,所以认为玩起来会很有趣.

首先,这是我刚创建的JSFiddle:http://jsfiddle.net/xHL35/1/

现在,API调用需要一个变量来保存它

 $(".scrollable").scrollable();
 var scrollapi = $(".scrollable").data("scrollable");

现在scrollapi,可以调用这样的函数:

scrollapi.next(200);

我已经复制了你自己的代码来选择图像,只是重写它以适应NEXT图像.我没有创建PREV函数,但不应该很难反转NEXT函数.

$(".nextImg").click(function(){
    // Count all images
    var count = $(".items img").length;

    // Finding the next image
    var next = $(".items").find(".active").next("img");
    // Is the next image, the last image in the wrapper?
    if(next.is(":last")){
        // If it is, go to next DIV and get the first image
        next = $(".items").find(".active").parent().next("div").find("img:first");
        // If this dosn't exists, we've reached the end
        if(next.index() == -1){
          // We have reached the end - start over.
          next = $(".items img:first");
          scrollapi.begin(200);
        } else {
          // Not at the end, show next div in thumbs
          scrollapi.next(200);
        }
    }

    // Get the current image number
    var current = (next.index("img"));

    var nextUrl = next.attr("src").replace("_t", "");

    // get handle to element that wraps the image and make it semi-transparent
    var wrap = $("#image_wrap").fadeTo("medium", 0.5);
    var wrap2 = $("#mies1");

    // the large image from www.flickr.com
    var img = new Image();

    // call this function after it's loaded
    img.onload = function() {
      // make wrapper fully visible
      wrap.fadeTo("fast", 1);
      // change the image
      wrap.find("img").attr("src", nextUrl);
      wrap2.find("img").attr("src", nextUrl);
    };

    // begin loading the image from www.flickr.com
    img.src = nextUrl;

    // Show the counter
    $("#imageCounter").html("Image: "+current+" of "+count);

    // activate item
    $(".items img").removeClass("active");
    next.addClass("active");

});

希望你能用它来开发画廊的其余部分.
