JSON HTML

JSON can be translated into JavaScript.

JavaScript can be used to make HTML on your web pages.

HTML Table

Create an HTML table with data received as JSON:

<!DOCTYPE html>

<html>

<body>

<h2>Make a table based on JSON data.</h2>

<p id=”demo”></p>

<script>

const dbParam = JSON.stringify({table:”customers”,limit:20});

const xmlhttp = new XMLHttpRequest();

xmlhttp.onload = function() {

  const myObj = JSON.parse(this.responseText);

  let text = “<table border=’1′>”

  for (let x in myObj) {

    text += “<tr><td>” + myObj[x].name + “</td></tr>”;

  }

text += “</table>”   

document.getElementById(“demo”).innerHTML = text;

}

xmlhttp.open(“POST”, “json_demo_html_table.php”);

xmlhttp.setRequestHeader(“Content-type”, “application/x-www-form-urlencoded”);

xmlhttp.send(“x=” + dbParam);

</script>

</body>
