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);
