      The JavaScript tutorial shows an easy method to extract the contents of a JSON file and output in an HTML webpage. Modify and expand on the script to meet your requirements.


      Step 1​


      Copy and paste the JS script below into the intended webpage. Update the data.json file location if different.

      Code:
      <script>
      // fetch the data.json file from with same folder - not remote
              fetch('data.json')
                  .then(function (response) {
                      return response.json();
                  })
                  .then(function (data) {
                      appendData(data);
                  })
                  .catch(function (err) {
                      console.log('error: ' + err);
                  });
      
      // create a function to extract the JSON data and create a HTML element to output
              function appendData(data) {
                  var mainContainer = document.getElementById("jsonData");
                  for (var i = 0; i < data.length; i++) {
      
      // create and output the data
                      var div = document.createElement("div");
                      div.innerHTML = 'Town: ' + data[i].town + ' ' + data[i].county;
                      mainContainer.appendChild(div);
                  }
              }
          </script>

      Step 2​


      Manually insert the div id shown below into the webpage HTML where you want to render the JSON file contents.

      Code:
      <div id="jsonData"></div>

      Contents of the data.json file​

      Code:
      [
          {
              "id": "1",
              "town": "Wigan",
              "county": "Greater Manchester"
          },
          {
              "id": "2",
             "town": "Oldham",
             "county": "Greater Manchester"
          },
          {
         "id": "3",
             "town": "Stockport",
             "county": "Greater Manchester"
          }
      ]
