Capture link and title, and move to a single modal

Question

A list of 5 articles, with different links and titles, each with a link Share that opens a modal, where it has four buttons to be shared on social media. To be shared it is necessary to have the post link. I think it would be disastrous to put the modal in a php loop, thus creating a specific modal for each article listed. What I want is to keep only one modal, and pass the link value/post title to it, with javascript through the button Share

PS: This is for a wordpress project, so each article listed has, ID own. id="post-150", id="post-50", id="post-650"

Example

jQuery(function($) {
    $('.popup-modal').magnificPopup({
        type: 'inline',
        preloader: false,
        focus: '#username',
        modal: true
    });
    $(document).on('click', '.popup-modal-dismiss', function (e) {
        e.preventDefault();
        $.magnificPopup.close();
    });

    
});

.post-article {
    border-bottom: 1px solid #eee;
    padding: 10px;
    margin-bottom: 10px;
}
.post-article:nth-child(odd) {
    background: #eee;
}

.post-article:nth-child(even) {
    background: #fafafa;
}
.popup-modal-dismiss {
    font-size: 22px;
    font-weight: bold;
    text-align: center;
}

Answer 1

This code does what you want, puts the title in the modal and assigns the appropriate links to each social network icon:

$('.popup-modal').on('click', function(){

   var comp = $(this).closest("article").find("h1 a"),
       url_ = comp.attr("href"),
       tit_ = comp.text();

   $("#test-modal div b").text('Título do post: '+tit_);

   var fb_link = "http://www.facebook.com/sharer.php?u="+url_, // facebook
       gp_link = "https://plus.google.com/share?url="+url_, // google+
       li_link = "http://www.linkedin.com/shareArticle?mini=true&url="+url_, // linkedin
       tw_link = "https://twitter.com/share?url="+url_+"&text="+tit_; // twitter

   $("#test-modal a").each(function(){

      var href = $(this).attr("href");

      if(~href.indexOf("facebook")) $(this).attr("href", fb_link);
      if(~href.indexOf("google")) $(this).attr("href", gp_link);
      if(~href.indexOf("linkedin")) $(this).attr("href", li_link);
      if(~href.indexOf("twitter")) $(this).attr("href", tw_link);

   });

});

I couldn’t play the snippet here, so follow example in Jsfiddle.
