如何在所有html5视频加载infinitescroll之后运行砌体？

Question

砌体无限滚动追加html5视频重叠

我目前正在使用imagesLoaded库来检查图像是否已加载然后调用masonry.

但它没有使用html5视频标签,因为这些视频相互重叠.

所以我改变调用masonry从document.ready到window.load并删除呼叫imagesLoaded从此即在初始加载

$(document).ready(function(){

    var $container = $('#media');
    // layout Masonry again after all images have loaded
    $container.imagesLoaded( function() {

      $container.masonry({
          "columnWidth": "." + "col-sm-2",
          itemSelector: '.item',
          gutter: 0,
        });
      $('.item').css('opacity', '1.0');
    });

});

对此

$(window).load(function(){
        var $container = $('#media');

          $container.masonry({
              "columnWidth": "." + "col-sm-2",
              itemSelector: '.item',
              gutter: 0,
            });
          $('.item').css('opacity', '1.0');
});

现在html5 videos在masonry重叠,并在页面的第一次加载完美渲染initial load,但是,因为我也使用在滚动页面上infinite-scroll添加更多images/videos,所以当新视频被添加到容器时它们正在重叠,这种行为是由早期引起的masonry在加载所有视频元素之前运行,因为imagesloaded无法检查videos loaded.

这是代码.

$(document).ready(function(){
    var $container = $('#media');
    var no_more_media = "<?= Lang::get('lang.no_more_to_load') ?>";
    var loading_more_media = "<?= Lang::get('lang.loading_more_media') ?>";

    $container.imagesLoaded(function(){
            $container.masonry();
        });

$container.infinitescroll({
        loading: {
            finished: undefined,
            finishedMsg: "<p>" + no_more_media + "</p>",
            img: "data:image/gif;base64,R0lGODlhAQABAHAAACH5BAUAAAAALAAAAAABAAEAAAICRAEAOw==",
            msg: null,
            msgText: "<div class='loading'><i></i><i></i><i></i></div><p>" + loading_more_media + "</p>",
            selector: null,
            speed: 'fast',
            start: undefined,
        },
        navSelector  : "ul.pagination",            
                       // selector for the paged navigation (it will be hidden)
        nextSelector : "ul.pagination a:first",    
                       // selector for the NEXT link (to page 2)
        itemSelector : ".container #media .item",
        animate: false,
        bufferPx: 160,
      },

      function( newElements ) {
         // hide new items while they are loading
        //var $newElems = 
        $.each($(newElements), function(index, value){
            item_click_events($(value));
        });

            $( newElements ).css({ opacity: 0 });

            $(newElements).imagesLoaded(function(){
               var $newElems = $( newElements );
               $newElems.animate({ opacity: 1 });
               $container.masonry( 'appended', $newElems, true);
            }
            );

      });
});

我已经尝试过更改document.ready为window.load上面的代码,并imagesloaded完全删除运行,但它无法使用infinitescroll.,

例如修改代码

$(window).load(function(){
    var $container = $('#media');
    var no_more_media = "<?= Lang::get('lang.no_more_to_load') ?>";
    var loading_more_media = "<?= Lang::get('lang.loading_more_media') ?>";

            $container.masonry();

    $container.infinitescroll({
        loading: {
            finished: undefined,
            finishedMsg: "<p>" + no_more_media + "</p>",
            img: "data:image/gif;base64,R0lGODlhAQABAHAAACH5BAUAAAAALAAAAAABAAEAAAICRAEAOw==",
            msg: null,
            msgText: "<div class='loading'><i></i><i></i><i></i></div><p>" + loading_more_media + "</p>",
            selector: null,
            speed: 'fast',
            start: undefined,
        },
        navSelector  : "ul.pagination",            
                       // selector for the paged navigation (it will be hidden)
        nextSelector : "ul.pagination a:first",    
                       // selector for the NEXT link (to page 2)
        itemSelector : ".container #media .item",
        animate: false,
        bufferPx: 160,
      },

      function( newElements ) {
         // hide new items while they are loading
        //var $newElems = 
        $.each($(newElements), function(index, value){
            item_click_events($(value));
        });

            $( newElements ).css({ opacity: 0 });

               var $newElems = $( newElements );
               $newElems.animate({ opacity: 1 });
               $container.masonry( 'appended', $newElems, true);

      });
});

我可以通过指定视频宽度和高度来解决这个重叠问题的另一种方法,但作为其响应式设计,指定视频宽度和高度会破坏响应性.

所以我的问题是,是否有任何js库simmilar到imagesloaded确保所有视频都加载,然后我可以打电话给砌体？或者我怎么能保证视频不会得到overlapped的infinitescroll？

更新1:

对于infinitescroll,我尝试了很多技巧

$(newElements).load(function(){
   var $newElems = $( newElements );
   $newElems.animate({ opacity: 1 });
   $container.masonry( 'appended', $newElems, true);
});

在pagescroll之后不会加载新内容.

$(window).load(function(){
   var $newElems = $( newElements );
   $newElems.animate({ opacity: 1 });
   $container.masonry( 'appended', $newElems, true);
});

在pagescroll之后不会加载新内容.

   var $newElems = $( newElements );
   $newElems.animate({ opacity: 1 });
   $container.masonry( 'appended', $newElems, true);

重叠视频内容

所以我想出了infinite-scroll提前打电话,放慢了container.masonry3秒,现在效果很好.但仍在等待正确的解决方案.

例如

bufferPx: 700,

setTimeout(function(){
       var $newElems = $( newElements );
       $newElems.animate({ opacity: 1 });
       $container.masonry( 'appended', $newElems, true);
}, 3000);

以上是延迟运行砖石3秒.

我试图寻找类似window.load的div,但没有,所以我的最好的办法是检查是否所有的videos和images被加载,然后调用masonry调用后infinite-scroll

看起来你可以通过等待视频的loadeddata事件来修复它

这是基本的想法:

function waitForvidLoad(vids, callback) {
     /* if no videos i.e. mobile mode only gifs and jpgs then call callback else masonry breaks.*/
        if(vids.length === 0){
            callback();
        }
    var vidsLoaded = 0;
    vids.on('loadeddata', function() {
      vidsLoaded++;
      if (vids.length === vidsLoaded) {
        callback();
      }
    });
  }

.

  var $container = $('#container');
  var vids = $('#container').find('video');
  waitForvidLoad(vids, function() {
    $container.imagesLoaded(function() {
      $container.masonry({
        itemSelector: '.box',
        columnWidth: 100
      });
  });
