HTML JSON: Tabel Code dan Cara Membuatnya

JSON dapat dengan mudah diterjemahkan ke dalam JavaScript.

JavaScript dapat digunakan untuk membuat HTML di halaman web.

Tabel HTML

Membuat tabel HTML dengan data yang diterima sebagai JSON.

Contoh:

<!DOCTYPE html>
<html>
<body>

<h2> Buat tabel berdasarkan data JSON. </h2>
<p id="demo"></p>

<script>
var obj, dbParam, xmlhttp, myObj, x, txt = "";
obj = { table: "customers", limit: 20 };
dbParam = JSON.stringify(obj);
xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    myObj = JSON.parse(this.responseText);
    txt += "<table border='1'>"
    for (x in myObj) {
      txt += "<tr><td>" + myObj[x].name + "</td></tr>";
    }
    txt += "</table>"    
    document.getElementById("demo").innerHTML = txt;
  }
};
xmlhttp.open("POST", "json_demo_html_table.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("x=" + dbParam);
</script>

</body>
</html>

Tabel HTML Dinamis

Membuat tabel HTML berdasarkan nilai menu drop down.

Contoh:

<!DOCTYPE html>
<html>
<body>

<h2>Buat tabel berdasarkan nilai dari menu drop down.</h2>
<select id="myselect" onchange="change_myselect(this.value)">
  <option value="">Pilih satu opsi:</option>
  <option value="customers">Customers</option>
  <option value="products">Products</option>
  <option value="suppliers">Suppliers</option>
</select>

<p id="demo"></p>

<script>
function change_myselect(sel) {
  var obj, dbParam, xmlhttp, myObj, x, txt = "";
  obj = { table: sel, limit: 20 };
  dbParam = JSON.stringify(obj);
  xmlhttp = new XMLHttpRequest();
  xmlhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      myObj = JSON.parse(this.responseText);
      txt += "<table border='1'>"
      for (x in myObj) {
        txt += "<tr><td>" + myObj[x].name + "</td></tr>";
      }
      txt += "</table>"    
      document.getElementById("demo").innerHTML = txt;
      }
    };
  xmlhttp.open("POST", "json_demo_html_table.php", true);
  xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  xmlhttp.send("x=" + dbParam);
}
</script>

</body>
</html>

List drop-down HTML

Membuat list drop-down HTML dengan data yang diterima sebagai JSON.

Contoh:

<!DOCTYPE html>
<html>
<body>

<h2>Buat daftar drop-down berdasarkan data JSON.</h2>
<p id="demo"></p>

<script>
var obj, dbParam, xmlhttp, myObj, x, txt = "";
obj = { table: "customers", limit: 20 };
dbParam = JSON.stringify(obj);
xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    myObj = JSON.parse(this.responseText);
    txt += "<select>"
    for (x in myObj) {
      txt += "<option>" + myObj[x].name;
    }
    txt += "</select>"
    document.getElementById("demo").innerHTML = txt;
  }
};
xmlhttp.open("POST", "json_demo_html_table.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("x=" + dbParam);
</script>

</body>
