jquery - Packery js 洗牌并适合容器

Question

所以我有一个 Packery 网格，希望随机排列元素，以便它们至少可以完美地组织到容器的高度......如果宽度关闭，那很好。

看这样的布局:

<div class="grid">
        <div class="grid-item grid-sizer"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/150x150" border="0" class="img-responsive" /></div>
        <div class="grid-item grid-item--width2"><img src="http://placehold.it/700x250" border="0" class="img-responsive" /></div>
        <div class="grid-item grid-item--width2"><img src="http://placehold.it/700x200" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
        <div class="grid-item grid-item--width2"><img src="http://placehold.it/700x200" border="0" class="img-responsive" /></div>
        <div class="grid-item grid-item--width2"><img src="http://placehold.it/700x200" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/150x150" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
        <div class="grid-item"><img src="http://placehold.it/350x150" border="0" class="img-responsive" /></div>
    </div>

一些通用样式:

.grid-sizer, .grid-item{
            width: 20%;
    float: left;

            img{
                width: 100%;
                height: auto;
            }
        }

        .grid-item--width2{
            width: 40%;
        }

最后，发起者:

var $grid = $('.grid').imagesLoaded( function() {
$grid.packery({
    columnWidth: '.grid-sizer',
    itemSelector: '.grid-item',
    gutter: 0,
    precentPosition: true
});

});

Answer 1

所以我决定，如果没有一些额外的 jquery(如果需要，我可以在以后编写)，就必须有上传规范。没有它就不可能避免差距，如果有人想打动我的心并向我展示，而不使用我知道可以做到的一堆 jQuery。

然而，洗牌，我确实写了一篇文章，然后将其打包备份，实际上大部分时间都做得非常好......在我标准化我的规范之前仍然存在一些差距。

var $grid = $('.grid');
var $gridItems = $grid.children('.grid-item');

$gridItems.sort(function(a, b) {
var tmp = parseInt(Math.random() * 10);
var isOddOrEven = tmp % 2;
var isPosOrNeg = tmp > 5 ? 1 : -1;
return (isOddOrEven & isPosOrNeg);
}).appendTo($grid);

shuffle($gridItems).appendTo($grid);

$('.grid').packery();

function shuffle(array) {
var currentIndex = array.length,
temporaryValue, randomIndex;

// While there remain elements to shuffle...
while (0 !== currentIndex) {

// Pick a remaining element...
randomIndex = Math.floor(Math.random() * currentIndex);
currentIndex -= 1;

// And swap it with the current element.
temporaryValue = array[currentIndex];
array[currentIndex] = array[randomIndex];
array[randomIndex] = temporaryValue;
}

return array;
}
