javascript - 实现流畅的 JS tile 界面

我正在建立一个摄影网站，我想创建一个漂亮的“平铺”界面，它看起来类似于新版 MSN Money Now 上的界面(注意 - 新版网站只能在Windows 8 电脑)- http://t.money.msn.com/now/ .我尝试用 Javascript 实现它。

这是一个带有预填充数据的示例页面:http://photoachiever.azurewebsites.net/en

我创建了瓷砖组 - 每个 2 个单位高，2 个单位宽，其中可以包含一个大方形瓷砖、两个宽瓷砖或四个小方形瓷砖。现在，因为我希望网站能够响应，所以我想在 Javascript 中动态计算最佳单元大小，以便总是 100% 的空间被填充，并且对于更宽的屏幕，例如更多的列可见等等。它在 MSN Money 网站上的工作方式相同，但有两个重要区别:

1) 当我的图片第一次加载时，我只会看到它们的最高结果，直到所有图片都加载完毕并执行 JS。 MSN Money 网站仅显示一个绿色区域，稍后会显示图像，并且已适当调整大小。2)当我调整窗口大小时，它远非流畅，计算和主要是图像大小调整非常明显。然而，在 MSN Money 上，调整大小非常流畅，甚至图像似乎也能毫无故障地调整大小。此外 - 他们设法使字体可以流畅地调整大小。

请您解释一下，MSN Money 网站是如何取得这些成果的？我在 Stack Overflow 上看到了一些类似的问题，但它们从未要求各个图 block 的宽度和高度相等，而我的设计确实需要这一点。

奖励问题:能否请您添加一些关于如何实现 div 的响应式动画回流的解释？在 http://www.brainyquote.com/ 上找到的示例- 当您更改窗口大小时，它会以动画方式重排所有引号。

编辑:我附上了我当前的代码，这远非正确(性能非常低，图像首先显得太大，并且在全部下载后它们的大小下降)。

代码的第一部分(将所有事件附加到图 block 并在点击时添加动画):

function attachTileEvents() {
if ($(".tile-flow").size() >= 1) {
    $(window).resize(function () {
        delay(function () {
            resizeTiles();
        }, 100);
    });
    $(document).on("click", ".tile-flow .load-next-page", manualLoadContentDetection);
    $(window).on("scroll", scrollLoadContentDetection);
    $(document).on("touchend", scrollLoadContentDetection);
}
resizeTiles();
$(".tile .contents").each(function () {
    var tile = $(this).parent()[0]
    var mouse = { x: 0, y: 0, down: false };

    var maxRotation = 16;
    var minScale = 0.95;
    var setRotation = function (scaled) {
        //Rotations as percentages 
        var width = tile.offsetWidth;
        var height = tile.offsetHeight;
        var diag = Math.sqrt((width / 2) * (width / 2) + (height / 2) * (height / 2));
        var dist = Math.sqrt((mouse.x - (width / 2)) * (mouse.x - (width / 2)) + (mouse.y - (height / 2)) * (mouse.y - (height / 2)));
        var fract = 1.0;
        if (dist > 0) {
            fract = dist / diag;
        }
        var yRotation = (mouse.x - (width / 2)) / (width / 2);
        var xRotation = (mouse.y - (height / 2)) / (height / 2);

        if (scaled) {
            tile.style.webkitTransform = "rotateX(" + -xRotation * maxRotation + "deg)" + " rotateY(" + yRotation * maxRotation + "deg)" + " scale(" + (minScale + fract * (1 - minScale)) + ")";
            tile.style.mozTransform = "rotateX(" + -xRotation * maxRotation + "deg)" + " rotateY(" + yRotation * maxRotation + "deg)" + " scale(" + (minScale + fract * (1 - minScale)) + ")";
            tile.style.transform = "rotateX(" + -xRotation * maxRotation + "deg)" + " rotateY(" + yRotation * maxRotation + "deg)" + " scale(" + (minScale + fract * (1 - minScale)) + ")";
        } else {
            tile.style.webkitTransform = "rotateX(" + -xRotation * maxRotation + "deg)" + " rotateY(" + yRotation * maxRotation + "deg)";
            tile.style.mozTransform = "rotateX(" + -xRotation * maxRotation + "deg)" + " rotateY(" + yRotation * maxRotation + "deg)";
            tile.style.transform = "rotateX(" + -xRotation * maxRotation + "deg)" + " rotateY(" + yRotation * maxRotation + "deg)";
        }
    }
    var MouseDown = function (e) { mouse.x = e.offsetX; mouse.y = e.offsetY; mouse.down = true; setRotation(true); }
    var MouseUp = function (e) { if (mouse.down) { mouse.down = false; tile.style.webkitTransform = "rotateX(0deg)" + " rotateY(0deg) scale(1.0)"; tile.style.mozTransform = "rotateX(0deg)" + " rotateY(0deg) scale(1.0)"; tile.style.transform = "rotateX(0deg)" + " rotateY(0deg) scale(1.0)"; } }
    var MouseOut = function (e) { mouse.down = false; tile.style.webkitTransform = "rotateX(0deg)" + " rotateY(0deg) scale(1.0)"; tile.style.mozTransform = "rotateX(0deg)" + " rotateY(0deg) scale(1.0)"; tile.style.transform = "rotateX(0deg)" + " rotateY(0deg) scale(1.0)"; }
    var MouseMove = function (e) { mouse.x = e.offsetX; mouse.y = e.offsetY; if (mouse.down == true) { setRotation(false); } }
    $(tile).on("mousemove", MouseMove);
    $(tile).on("mousedown", MouseDown);
    $(tile).on("mouseup", MouseUp);
    $(tile).on("mouseout", MouseOut);
});}

主要部分 - 调整大小:

var TileSizes = { wideWidth: 0, singleWidth: 0, margin: 0 };
function resizeTiles() {
var rowColumnNumber = 2;
var width = $(window).width();
if (width >= 2500) {
    rowColumnNumber = 7;
}
else if (width >= 2000) {
    rowColumnNumber = 6;
} else if (width >= 1600) {
    rowColumnNumber = 5;
} else if (width >= 1280) {
    rowColumnNumber = 4;
} else if (width >= 768) {
    rowColumnNumber = 3;
} else if (width >= 480) {
    rowColumnNumber = 2;
} else {
    rowColumnNumber = 1;
}
var totalWidth = $(".tile-flow").width() - 17; //compensate for the scrollbar
//calculate the margin size : 5% of the flow width
var margin = Math.round(totalWidth * 0.05 / rowColumnNumber);
var wideSize = Math.floor((totalWidth - margin * (rowColumnNumber - 1)) / rowColumnNumber);
var halfSize = Math.floor((wideSize - margin) / 2);
var quaterSize = Math.floor(halfSize * 2.5 / 3);
var heightSize = Math.floor(halfSize * 2 / 2.0);
var doubleHeightSize = heightSize * 2 + margin;
var detailsSize = quaterSize * 2 + margin;
TileSizes.wideWidth = doubleHeightSize;
TileSizes.singleWidth = heightSize;
TileSizes.margin = margin;
$(".big-square-tile").width(doubleHeightSize);
$(".big-square-tile").height(doubleHeightSize);

$(".tile-flow .col .small-tile:even").css("margin-right", margin);

$(".wide-tile").height(heightSize);
$(".col").width(doubleHeightSize);
$(".col").css("margin-right", margin);
$(".col:nth-child(" + rowColumnNumber + "n)").css("margin-right", 0);
//all tiles get bottom margin

var how = 0;
$(".wide-tile .contents footer").each(function () {
    if ((how % 4 == 0) || (how % 4 == 1)) {
        $(this).width(TileSizes.singleWidth - 20);
    } else {
        $(this).height(75);
    }
    if (how % 4 == 0) {

    how = how + 1;

    how = how + 1;
});

$(".tile").css("margin-bottom", margin);
//resize images    
var imageList = Array();

    imageList.push($(this));
    var img = new Image();
    img.onload = function () {

        var index = parseInt(this.id.replace("RESIZINGBIG", ""));
        if (originalHeight > originalWidth) {
            imageList[index].css("height", "auto");
            imageList[index].css("width", "100%");

最佳答案

如果我是你，我会使用 Isotope 作为基本布局并添加幻灯片放映并在其旁边单击事件。您可以插入几乎任何您喜欢的内容。 jQuery Isotope.

Updated Working Model

Full page result

JS

$(function () {

    var $container = $('#container');

    $container.imagesLoaded(function () {
        $container.isotope({
            itemSelector: '.photo'
        });
    });
});


var $container = $('#container');
// initialize Isotope
$container.isotope({
    // options...
    resizable: false, // disable normal resizing
    // set columnWidth to a percentage of container width
    masonry: {
        columnWidth: $container.width() / 5
    }
});

// update columnWidth on window resize
$(window).smartresize(function () {
    $container.isotope({
        // update columnWidth to a percentage of container width
        masonry: {
            columnWidth: $container.width() / 5
        }
    });
});

//click function

    $(function () {
        $('.photo').click(function () {
            $(this).toggleClass('red');
        });
    });

//hover function

    $(function () {
        $('#photo1').hover(function () {
            $('#info1').fadeToggle();
        });
    });

概念验证 - Isotope 内的动画

请注意，此动画在使用前完全是微调。

 function animatie() {
     var d = 0;
     for (var i = 0; i < 3; ++i) {
         var b = "#info" + i;
         $(b).css('background', 'silver');
         $(b).hide().delay(d).slideDown(1000).delay(3000).slideUp(1000);
         d += 5000;
     }
 }
 animatie();
 window.setInterval(animatie, 15000);

 $(function () {
     for (var i = 0; i < 3; ++i) {
         var z = '.box' + i;
         var divHeight = $(z).height();
         $(z).css('max-height', divHeight + 'px');
         $(z).css('max-height', divHeight + 'px');
         $(z).css('overflow', 'hidden');
     }
 });
 $(window).resize(function () {
     for (var i = 0; i < 3; ++i) {
         var z = '.box' + i;
         var divHeight = $(z).height();
         $(z).css('max-height', divHeight + 'px');
         $(z).css('overflow', 'hidden');
     }
 });

这是一个非常酷的布局、排序和过滤插件。它将为您提供图 block 和动画作为基本功能。
