如何自动播放图库的动画

标签： javascript jquery html css

我有一个图片库的下页，当您将鼠标悬停在图像上时，描述会滑出并放大图像。它工作正常。然而我想知道，而不是不得不用鼠标悬停我想访问页面和图库中的随机图像放大和描述滑出并恢复正常，然后移动到另一个图像，然后到下一个。所以，只需在访问该页面时澄清：

  1. 按随机顺序，图库中的图像放大，描述滑出，然后返回原始状态，然后移到下一张图像上。
  2. 图库中的下一个随机图像放大，描述滑出等等

    3. 全部按随机顺序排列。

    ＆＃13;
    ＆＃13; 
    $(function() {
  // View the selected photo at full size
  $(".photo-image").click(function() {
    $(this).addClass("photo-selected");
    $(this).parent().addClass("photo-x");
    $("#overlay").show();
  });

  // Close the full size view when #overlay is clicked
  $("#overlay").click(function() {
    $(".photo-image").removeClass("photo-selected");
    $(".photo-x").removeClass("photo-x");
    $("#overlay").hide();
  });
});

// Close full size view if "esc"
$(document).keyup(function(e) {
  if (e.keyCode == 27) {
    $(".photo-image").removeClass("photo-selected");
    $("#overlay").hide();
  }
});

2 个答案:

答案 0 :(得分：0)

*****************这只是＆＃39; jQquery＆＃39;实施********************

没有随机化

1.首先确保页面已满载，现在应该执行动画。

使用$( window ).load(function() { //all code written below here })

2.现在迭代每个孩子并暂停，然后再去下一个。使用.find()和How to add pause between each iteration of jQuery .each()? $('.imagepluscontainer').find('img').each(function () { //jquery animation code goes here //remember to remove hover // now pause between different itterations };

执行此操作

随机化

如果您想随机化图像选择程序，我会发现遵循最简单的方法：

  1. 不是逐个遍历子元素，而是可以创建子img元素的数组。 eg- 
    2. var imgplusArray = $(".imagepluscontainer").find("img").toArray();
    1. 现在我们有了阵列，我们可以轻松地将其洗牌。 使用以下javascript（是的，javascript）函数 - 
      2. function shuffleArray(array) {
    for (var i = array.length - 1; i > 0; i--) {
        var j = Math.floor(Math.random() * (i + 1));
        var temp = array[i];
        array[i] = array[j];
        array[j] = temp;
    }
    return array;
}
shuffleArray(imgplusArray);
      1. 现在我们有了混洗数组，我们只需要遍历数组而不是像之前那样的子代。 How to add pause between each iteration of jQuery .each()? 
        2. $(imgplusArray).each(function () { //jquery animation code goes here
//remember to remove hover
// now pause between different itterations
};

答案 1 :(得分：0)

您应该使用其他CSS类，使用jQuery为图像添加悬停效果。假设班级名称为hovered。为CSS和:hover添加.imagepluscontainer中使用的相同.photo-image属性，如下所示。

.photo-image.hovered {
     width: 200px;
     top: -50px;
     left: -50px;
     z-index: 1001;
     opacity: 1;
}
.imagepluscontainer.hovered div.desc {
    -moz-transform: translate(0, 100%);
    -webkit-transform: translate(0, 100%);
    -ms-transform: translate(0, 100%);
    -o-transform: translate(0, 100%);
    transform: translate(0, 100%);
    opacity: 1;
}
.imagepluscontainer.hovered div.rightslide {
    -moz-transform: translate(100%, 0);
    -webkit-transform: translate(100%, 0);
    -ms-transform: translate(100%, 0);
    -o-transform: translate(100%, 0);
    transform: translate(100%, 0);
    z-index: 2001;
}
.imagepluscontainer:hovered div.leftslide {
    -moz-transform: translate(-100%, 0);
    -webkit-transform: translate(-100%, 0);
    -ms-transform: translate(-100%, 0);
    -o-transform: translate(-100%, 0);
    transform: translate(-100%, 0);
}
.imagepluscontainer.hovered div.upslide {
    -moz-transform: translate(0, -100%);
    -webkit-transform: translate(0, -100%);
    -ms-transform: translate(0, -100%);
    -o-transform: translate(0, -100%);
    transform: translate(0, -100%);
}

您可以使用javascript setInterval功能在间隔后连续添加悬停效果。使用Math.random()选择随机元素，如下所示。 

setInterval(function(){
    $('.imagepluscontainer').removeClass('hovered');
    $('.photo-image').removeClass('hovered');

    var x = Math.floor((Math.random() * ($('.imagepluscontainer').length-1)) + 0);
    $('.imagepluscontainer').eq(x).addClass('hovered');
    $('.photo-image').eq(x).addClass('hovered');
}, 2000);

希望这会对你有所帮助。
