计算JavaScript的每日复利

Question

我需要一些帮助。我是新手。我正在尝试计算每日复利。我尝试了以下代码，但是没有用。我想要与此Calculate Image类似的内容。感谢您的帮助。

这是我的代码。但这不起作用

// var totalI =  (amount* Math.pow((1 + (0.012/(365))), (365*(period|365)))));

 $(function(){
            var period = document.getElementById("period").value;
            var amount = document.getElementById("amount").value;
            if(document.getElementById("period").selectedIndex == 3){

                    document.getElementById("other").style.display='block';


                    period = document.getElementById("other").value;

                    period = period * 30;

                } else {
                    document.getElementById("other").style.display='none';
                    var period = document.getElementById("period").value;
                }

           var totalI =  (amount* Math.pow((1 + (0.012/(365))), (365*(period|365))))); 

            var inves = amount;
            var totalAmount = +inves + +totalI;
            //totalAmount = totalAmount + period
            if(period == ""){

                totalAmount = 0;


            } else {

                totalAmount = +inves + +totalI;

            }
             document.getElementById("total_p").value = "$" + round(totalAmount,2);
            document.getElementById("price_g").value = "$" + round(totalI,2);
            document.getElementById("inves_amount").value = "$" + inves;

     });
