JSON HTML


JSON can very easily be translated into JavaScript.
JavaScript can be used to make HTML in your web pages.

HTML Table
Make an HTML table with data received as JSON:

Example

const dbParam = JSON.stringify({table:"customers",limit:20});
const xmlhttp = new XMLHttpRequest();
xmlhttp.onload = function() {
  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);

Dynamic HTML Table
Make the HTML table based on the value of a drop down menu:


Choose an option:
Customers
Products
Suppliers





Example

<select id="myselect" onchange="change_myselect(this.value)">  <option value="">Choose an option:</option>  <option
value="customers">Customers</option>  <option
value="products">Products</option>  <option
value="suppliers">Suppliers</option></select>
<script>
function change_myselect(sel) {
  const dbParam = JSON.stringify({table:sel,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>
