jQuery Masonry and Ajax Append Items?

Question

I am trying to use some ajax and the jQuery Masonry plugin to add some items - but for some reason the new items aren't getting the masonry applied ?

I'm using

jQuery.ajax({
    type: "POST",
    url: ajax_url,
    data: ajax_data,
    cache: false,
    success: function (html) {
        if (html.length > 0) {
            jQuery("#content").append(html).masonry( 'appended', html, true );
        }
    });
});

However the items that are appended subsequently don't have the class="masonry-brick" applied which means that they stuff up completely the positioning ?

Answer 1

Had a similar problem and instead used the following line (converted for your code). Sorry, I don't recall where I found it.

In your code replace this:

jQuery("#content").append(el).masonry( 'appended', el, true );

With this:

jQuery("#content").append(el).masonry( 'reload' );

Answer 2

I added the following code after the append command and everything was fine:

$grid.imagesLoaded().progress( function() {
    $grid.masonry('layout');
});

The reason:

Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download at imagesloaded.desandro.com.

Just for future people who find this issue and the above solutions don't work for them: I found an issue with my selector and the element I added not having the same case, i.e. itemSelector was .Card but I was appending <div class="card">.

Hope this helps.

It appears that the masonry function expects a jQuery object as its second parameter and not a raw HTML string. You should be able to fix this by wrapping the success callback parameter like so:

jQuery.ajax({
    type: "POST",
    url: ajax_url,
    data: ajax_data,
    cache: false,
    success: function (html) {
        if (html.length > 0) {
            var el = jQuery(html);
            jQuery("#content").append(el).masonry( 'appended', el, true );
        }
    });
});

This solution works for me:-

  jQuery.ajax({
    type: "POST",
    url: ajax_url,
    data: ajax_data,
    dataType: 'json',
    cache: false,
    success: function(response) {
      if (response.length > 0) {
        var $container = $('#container');
        var msnry = $container.data('masonry');
        var elems = [];
        var fragment = document.createDocumentFragment();
        for (var x in response) {
          var elem = $(response[x]).get(0);
          fragment.appendChild(elem);
          elems.push(elem);
        }
        $container.appendChild(fragment);
        msnry.appended(elems);
      }
    }
  });

Following has worked for me. I have an ajax which returns set of html items (returns a partial view, from the ajax) when I click a load more button in my web page. Below is the partial view, which is dynamically generated.

foreach (var item in Model.SocialFeedList)
{
        <div class="grid-item">
            <div class="grid-inner">
                <div class="img-holder" style="background-image:url(imageURLHere)">
                </div>
                <div class="content-area">
                    <h3><a target="_blank" href="SomeLink">TitleOfTheLink</a></h3>
                    <p>SomeDescription</p>
                    <h5 class="date"><span>Published</span>: 2016/07/13</h5>
                </div>
            </div>
        </div>
}

In the success callback ajax method, I have done the below,where "response" is the set of html items I get from the above html. Where "divFeedList" is the root element where I show the set of html elements.

jQuery("divFeedList").append(response).masonry('reloadItems', response, true).masonry();

Please let me know if the answer is unclear.
