JSON HTML

Ang JSON ay napakadaling maipalit bilang JavaScript.

Ang JavaScript ay maaring gamitin para gumawa ng HTML sa web page.

HTML table

Gamitin ang data na natanggap bilang JSON upang bumuo ng table:

实例

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_db_post.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send("x=" + dbParam);
