HTML JSON
JSON pode ser facilmente traduzido para JavaScript.
JavaScript pode ser usado para fazer HTML em suas páginas da web.
Tabela HTML
Faça uma tabela HTML com os dados recebidos como JSON:
Exemplo
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);
Tabela HTML dinâmica
Faça a tabela HTML com base no valor de um menu suspenso:
Exemplo
<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>
Lista suspensa HTML
Faça uma lista suspensa HTML com os dados recebidos como JSON:
Exemplo
const dbParam = JSON.stringify({table:"customers",limit:20});
const xmlhttp = new XMLHttpRequest();
xmlhttp.onload = function() {
const myObj = JSON.parse(this.responseText);
let text = "<select>"
for (let x in myObj) {
text += "<option>" + myObj[x].name + "</option>";
}
text += "</select>"
document.getElementById("demo").innerHTML = text;
}
}
xmlhttp.open("POST", "json_demo_html_table.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("x=" + dbParam);
