[SOLVED] JavaScript Table Pagination Rendering JSON Data

JavaScript Table Pagination Rendering JSON Data

I'm fetching data in JSON format from a URL and rendering it to a table, but I need to show only 10 rows per page and I am not sure how to do it

Here is the code to render the data:

const url = "https://gist.githubusercontent.com/bstech-ux/e717b74dbd7cc95a8429eadc83a5c882/raw/ca85214d461ef93c316a47a6770c4b9ba678a6b3/movies.json";
    // Get JSON Data and Loop Through Each Object in the Array
    $.getJSON(url, (data) => {
        // parsePaginationData(data);
        let movie_data = "";
        // Append Data to movie_data Variable
        $.each(data, (key, value) => {
            movie_data += 
            `<tr>
                <td scope="row">${value.id}</td>
                <td>${value.title}</td>
                <td>${value.director}</td>
                <td>${value.distributor}</td>
                <td class="rating">${value.imdb_rating}</td>
                <td class="votes">${value.imdb_votes}</td>
                <td><button type="button" class="btn btn-danger">Delete</button></td>
            </tr>`;
        });

        $('#movies').append(movie_data);

    });

Solution

Store you data in an array.

The fuunction displayMovie will take a page parameter (default 1) and display movies depends on wich page you want.

To know how many page there are, use Math.ceil. With this number you can append as many as "pagination button" you need.

let movies = [];
const url = "https://gist.githubusercontent.com/bstech-ux/e717b74dbd7cc95a8429eadc83a5c882/raw/ca85214d461ef93c316a47a6770c4b9ba678a6b3/movies.json";
    // Get JSON Data and Loop Through Each Object in the Array
    $.getJSON(url, (data) => {
        movies = data;
        displayMovies();
        setPages();
    });
    
    function displayMovies(page = 1){
       let movie_data = "";
       let max = page*10;
       let min = max-10;
        // Append Data to movie_data Variable
        for(let i = min; i < max; i++){
          let movie = movies[i];
           if(movie){
            movie_data += 
            `<tr>
                <td scope="row">${movie.id}</td>
                <td>${movie.title}</td>
                <td>${movie.director}</td>
                <td>${movie.distributor}</td>
                <td class="rating">${movie.imdb_rating}</td>
                <td class="votes">${movie.imdb_votes}</td>
                <td><button type="button" class="btn btn-danger">Delete</button></td>
            </tr>`;
           }else{
            break;
           }
        }
       

        $('#movies').html(movie_data);
    }
    
    
    function setPages(){
      let nbPages = Math.ceil(movies.length/10);
      let pages = "";
      for(let i = 1; i <= nbPages; i++){
       pages+='<button type="button" onClick="displayMovies('+i+')">Page '+i+'</button>'
      }
       $('#pages').append(pages);
     
    }
