加载新内容并跟踪最旧的文章[关闭]

Question

I have never actually learned how to create a blog or anything the like up to now. I would like to create a personal portfolio/homepage, which will load older articles as soon as the user pushes the "load more" button. Now, I have it all set up, but I don't really know how to keep track of the oldest article ID.

As mentioned, here I load articles from a php script via AJAX.

$('#more_articles_button').click(function () {

    $.ajax({ url: kBaseUrl+"content_loader.php",
        data: {
               action: 'load_more_articles', 
               article_id: 'insert_lowest_article_id'
        },
        type: 'post',
        success: function(output) {

                 $('#articles_container').append(output);

        }
    });

});

Here I would like to get the last article's id and send it to the php script. How do I get hold of it ?

Answer 1

Put the article id in the id's attribute of your article's div and a common class in them (say, 'article'), and, using JQuery, iterate through them to get the maximum value:

var max_id = 0;
$('.article').each(function(i, object) {
    curr_id = $(object).attr('id');
    if (curr_id > max_id)
        max_id = curr_id;
});

//Afterwards, your ajax JQuery call
