আমার দুটি অংশে একটি সুস্পষ্ট সংজ্ঞাযুক্ত এজেএক্স ফিল্টার রয়েছে, একটি লোড বেশি বোতামের জন্য এবং একটি ড্রপ ডাউন ফিল্টার নির্বাচনের জন্য। উভয়ই এজেএক্সের সম্মুখ-প্রান্তে সম্পত্তিগুলির তালিকা পুনরায় লোড করে এবং একসাথে একসাথে কাজ করে (যেমন আমি যদি ন্যূনতম দাম, সর্বোচ্চ দাম এবং ড্রপডাউনগুলিতে বিছানার সংখ্যা, তালিকাটি রিফ্রেশ করে এবং আরও বেশি বোতামটি যেমন প্রয়োজন তেমনি কাজ করে) ।
একই ফিল্টারগুলি ইউআরএল পরামিতিগুলির সাথেও কাজ করে। সুতরাং উদাহরণস্বরূপ, যদি URL টি ছিল:
mydomain.com/?min_price=100000&max_price=5000000&beds=3&page=3
এটি para পরামিতি দ্বারা ফিল্টার হবে। এমনকি এটি 3 পৃষ্ঠার মূল্যবান বৈশিষ্ট্যগুলি যেমনটি দেখায় তেমনটি দেখায়। এটি প্রাথমিক লোড সহ, দুর্দান্ত কাজ করে। যাইহোক, এটি পৃষ্ঠাবদ্ধকরণের সাথে কাজ করে না, যদি URL টি সরাসরি লোড হয় is যদি আমি উপরের ইউআরএলটি সরাসরি ব্রাউজারে প্রবেশ করি এবং লোড করি তবে প্রাথমিক ফলাফলগুলি সঠিক হয় তবে আরও লোড করুন বোতামটি ক্লিক করার পরে এটি পৃষ্ঠা = 3 থেকে পৃষ্ঠা = 4 (সঠিক) পরিবর্তন করে তবে এটি সংযোজন সম্পন্ন বৈশিষ্ট্যের দ্বিতীয় পৃষ্ঠায় যুক্ত হয় , এবং এটি চালিয়ে যাওয়া - ফিল্টারকৃত পৃষ্ঠাগুলি চালিয়ে যাওয়ার চেয়ে।
আমি কি ভুল করছি?
এখানে আমার কোড (দুঃখিত এটি অনেক!)
