Convert JSON data to HTML table

srikanthpilli — Wed, 24 May 2017 18:35:57 GMT

Hello,

I am looking to find a way where I can convert JSON data to HTML table - where it should capture and display only the "name" and "alias" attributes into the HTML table from the following external json url :

https://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/0?f=pjson

Could you please provide your inputs on it.

Thanks

Srikanth

So you just want to show the values for the alias and field name? If so something like this should work.

<!DOCTYPE html>
<html>
<head>
  <title>JSON Content</title>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
  <link rel="stylesheet" href="https://js.arcgis.com/3.20/esri/css/esri.css">
  <style>
     table, th, td {
           border: 1px solid #ccc;
           border-collapse: collapse;
      }
      th, td{
        padding:0.5em;
      }
  </style>

  <script src="https://js.arcgis.com/3.20/"></script>
  <script>
    require([
        "dojo/dom",
        "dojo/on",
        "dojo/dom-class",
        "dojo/_base/json",
        "esri/config",
        "esri/request",
        "dojo/domReady!"
      ],
      function(
        dom,
        on,
        domClass,
        dojoJson,
        esriConfig,
        esriRequest
      ) {


          esriConfig.defaults.io.proxyUrl = "url to proxy";

          var requestHandle = esriRequest({
            "url": "https://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/0",
            "content": {
              "f": "json"
            }
          });
          requestHandle.then(createTable, function(error){
            console.log("Request Failed");
          });
    

        function createTable(response, io){
     
        
          var tbl = document.getElementById("tableDiv");
          var tblBody = document.createElement("tbody");

          var header = tbl.createTHead();
          var headerRow = header.insertRow(0);
          var headerCell = document.createElement("th");
          headerCell.innerHTML = "Name";
          headerRow.appendChild(headerCell);
          var headerCell2 = document.createElement("th");
          headerCell2.innerHTML = "Alias";
          headerRow.appendChild(headerCell2);




          response.fields.forEach(function(field){
            var row = document.createElement("tr");
            var cell = document.createElement("td");
            var cell2 = document.createElement("td");
            cell.innerHTML = field.name;
            cell2.innerHTML = field.alias;
            row.appendChild(cell);
            row.appendChild(cell2);
            tblBody.appendChild(row);
          });
          
          tbl.appendChild(tblBody);
  
   

        }
       
    });
  </script>

</head>

Thanks Kelly for looking into it, I copied your code and executed - it doesn't provide any results.

Am I missing anything?

Thanks

You'll need to setup a proxy and enter the proxy url on line 38 or use a service running on a server that supports CORS. Details can be found here:

Hi,

Here is an implementation of the same solution given by @KellyHutchins through Jquery and without a proxy. Working link to JSBin.

<!DOCTYPE html>
<html>
<head>
  <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
  <script type="text/javascript">
          $(document).ready(function(){               
                    $.ajax({
                         url: "https://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/0",
                         data: "f=pjson",
                         success: function (data) {
                              //console.log(data);
                              createTable(data);
                         }
                    }); 
          });
          
          function createTable(response){
     
        
          var tbl = document.getElementById("tableDiv");
          var tblBody = document.createElement("tbody");

          var header = tbl.createTHead();
          var headerRow = header.insertRow(0);
          var headerCell = document.createElement("th");
          headerCell.innerHTML = "Name";
          headerRow.appendChild(headerCell);
          var headerCell2 = document.createElement("th");
          headerCell2.innerHTML = "Alias";
          headerRow.appendChild(headerCell2);

          JSON.parse(response).fields.forEach(function(field){
            var row = document.createElement("tr");
            var cell = document.createElement("td");
            var cell2 = document.createElement("td");
            cell.innerHTML = field.name;
            cell2.innerHTML = field.alias;
            row.appendChild(cell);
            row.appendChild(cell2);
            tblBody.appendChild(row);
          });
          
          tbl.appendChild(tblBody);
        }
