    // 1: JSON decode with JavaScript eval function
    var jsontext1 = '({"id": 5, "url": "http://www.heig-vd.ch"})';
    var object1 = eval(jsontext1);
    console.log(object1);

    // 2: JSON decode with browser native implementation
    if (typeof JSON != "undefined") {
        var jsontext2 = '{"id": 5, "url": "http://www.heig-vd.ch"}';
        var object2 = JSON.parse(jsontext2);
        console.log(object2);
    }

    // 3: JSON encode with browser native implementation
    if (typeof JSON != "undefined") {
        var object3 = new Object();
        object3.id = 5;
        object3.url = "http://www.heig-vd.ch";
        var jsontext3 = JSON.stringify(object3);
