大家好，



我有一个简单的任务，但对我的网站上的java或编码知之甚少我有一个我想要的在线支付表格作为支付金额的字段，加上1％作为附加费通知客户，当他们接受时，然后用新金额更新原始字段，有人可以帮我提供这个代码吗？

推荐答案

我不确定java语法，但你可以试试这样的东西。它简单的数学问题

i am not sure about java syntax but you can try something like this. its simple maths problem

var newamount = oldamount(origional amount) * 1(this is your percentage)/100;

您需要带关心小数点精度或有时从字符串到十进制的转换可能是。



希望这会有所帮助。

您好，



试试这个JavaScript

Hi,

Try this JavaScript

<script type="text/ecmascript">
        function calculate()
        {
            var onePerc = amount * (percentage/ 100);
            alert(onePerc);
        }
    </script>
