Dubai Burj Al Arab Al Iwan Restaurant Reservation for Lunch or Dinner tours, activities, fun things to do in Dubai(United Arab Emirates)｜VELTRA (2024)

As an expert in web development and programming languages, particularly JavaScript and jQuery, I have a deep understanding of the code snippet you provided. My extensive experience in software development allows me to dissect and explain the concepts used in the code effectively. Let's delve into the details of the provided JavaScript code:

num_count++;

Here, num_count is being incremented by 1. This suggests that the variable num_count is likely used to keep track of a count or quantity in the broader context of the program.

if (result.AcActivity.length > 0) {
    if (result.AcActivity.length == 1 && (result.AcActivity[0]['id'] == current_ac_id)) {
        // Skip, if there's only 1 recommendation, and it is the current AC
    } else {
        $('#history-card').removeClass('d-none');
        $('#category_recentlist_v2020').html(div);
        $('#history_h3_title').html(h3_inner_title);
        $('.historycard-carousel').vcarousel({
            slidesToScroll: 4,
            dots: false,
            enableSlickForMobile: false,
            navArrowTheme: 2
        });
    }
}

In this block of code, the conditions are checking the length of the result.AcActivity array. If it has at least one element, it enters the first if statement. Inside that, it further checks if there is only one recommendation (result.AcActivity.length == 1) and if that recommendation's ID matches the current activity's ID. If both conditions are true, it skips the block; otherwise, it executes a series of jQuery actions.

• $('#history-card').removeClass('d-none'); removes the 'd-none' class from the HTML element with the ID 'history-card', making it visible.
• $('#category_recentlist_v2020').html(div); sets the HTML content of the element with the ID 'category_recentlist_v2020' to the value of the variable div.
• $('#history_h3_title').html(h3_inner_title); sets the HTML content of the element with the ID 'history_h3_title' to the value of the variable h3_inner_title.
• $('.historycard-carousel').vcarousel({...}); initializes a carousel using the jQuery plugin 'vcarousel' on elements with the class 'historycard-carousel', configuring various options like the number of slides to scroll, dots, mobile slick functionality, and navigation arrow theme.

}}});}}};

The multiple closing braces indicate the end of nested structures (likely nested callback functions or conditional blocks). It's crucial to have a well-structured codebase to maintain readability and avoid errors.

In summary, the provided JavaScript code is a part of a larger web application, likely related to recommending and displaying activities. It utilizes jQuery for DOM manipulation and incorporates conditional logic to determine whether to display a history card with recent activities and configure a carousel for these activities. The code reflects a practical implementation of frontend web development concepts, showcasing proficiency in JavaScript and jQuery.
