你如何转换onclick事件，以便他们在iPad上工作？

Question

以下是需要转换的内容：

是否

            function calculateTotal() {
                //Here we get the total points by calling our functions
                var totPoints = 0+get_r1()+get_r2()+get_r3();

                //display the result
                var divobj = document.getElementById('totalPoints');
                divobj.style.display='block';
                divobj.innerHTML = "Total: "+totPoints;                         
            }
