I\'m using

Answer 1

var mediaItemContainer = $( '#container' );
mediaItemContainer.masonry( {
    columnWidth:  '210px',
    itemSelector: '.item'
} );
$( mediaItemContainer ).prepend( '<div class="item">foo</div>' );
$( mediaItemContainer ).masonry( 'reloadItems' );
$( mediaItemContainer ).masonry( 'layout' );

Solution

Answer 2

I found a solution that works fine for me. it reloads every half second the layout of an instance of masonry.

//initialization of a masonry object:

var msnry = new Masonry("#container",{
itemSelector: '#post',
gutter: 15
}); 

//thread that makes the magic happens:

setInterval(function(){
msnry.reloadItems();
msnry.layout();
},500);

this way, you can append things using ajax, and voilá, there is the masonry layout.

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.

For Masonry v3.2.2 (latest at the time of this post), this is what works:

Assuming newHtml is a string like this:

<li>item 1</li><!--split-->
<li>item 2</li><!--split-->
<li>item 3</li>

You process it like this:

$.get(apiUrl, function(newHtml) {
    var textArr = newHtml.split("<!--split-->");
    var elArr = [];
    $.each(textArr, function(i,v) {
        if (v) {
            elArr.push($(v)[0]);
        }
    });
    $(this).append(elArr);
    $container.waitForImages( function() {
        $container.masonry('appended', elArr);
    });
}

Took me 2 hours to find out this!

I had the same problem with my ajax listing, i could solve it by calling reloadItems & layouts functions after ajax respond :

var mediaItemContainer = $( '#container' );
mediaItemContainer.masonry( {
    columnWidth:  '210px',
    itemSelector: '.item'
} );
$( mediaItemContainer ).prepend( '<div class="item">foo</div>' );
$( mediaItemContainer ).masonry( 'reloadItems' );
$( mediaItemContainer ).masonry( 'layout' );

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 );
        }
    });
});
