                    var template = document.createElement("li");
                    template.innerHTML = "<div></div><a href='#' class='update'>Update</a>";                

                    document.getElementById("placeholder").appendChild(template);
                }

                var newObject = new draw();

                var shapeArr = [];

            }

            var btn = document.getElementById("btn");
            btn.addEventListener("click", add, false);

        </script>       
    </body>
</html>

Answer 1

使用Array.push() 。

shapeArr.push(newObject);

Answer 2

You can use the push() method of the JavaScript Array to add new elements to the end:

var newObject = new draw();
var shapeArr  = [];

// add the new Object
shapeArr.push(newObject);
