Question

以下是我的javascript计算工具，您可以在其中显示值的百分比。好吧，如果价值是100美元，百分比是10％那么它将是10美元。之后，我刚刚添加了一个名为“其他费用”的新字段，因此最终结果将为20美元（如果其他费用值为10美元）。但无法得到结果。

Javascript Part：

<script type="text/javascript">
function incrementValue()
{
    var value = parseInt(document.getElementById('pvalue1').value, 10);
    value = isNaN(value) ? 0 : value;

    document.getElementById('pvalue1').value = value;
}

function decrementValue()
{
    var value = parseInt(document.getElementById('pvalue1').value, 10);
    value = isNaN(value) ? 0 : value;
    value -=10000
    document.getElementById('pvalue1').value = value;
}

function incrementValueO()
{
    var value = parseInt(document.getElementById('otherFees').value, 10);
    value = isNaN(value) ? 0 : value;

    value -=0.1
    value = parseFloat(value).toFixed(2)
    document.getElementById('pvalue2').value = value;

jQuery(document).ready(function(){

Html Part：

Answer 1

您还没有为otherFee编写更改功能，这可能如下所示，并将包含在就绪功能中。

 $('#otherFees').change(function(){
 var agentfee = parseFloat($('#pvalue1').val(), 10) * parseFloat($('#pvalue2').val(), 10) / 100; 
 var otherFees = parseFloat(document.getElementById('otherFees').value);
 var totalOtherFees = agentfee + otherFees;
 $('#pvalue3').val(totalOtherFees);

 var percentagereduce = parseFloat($('#pvalue2').val(), 10) - 0.1;
 var newvalue = parseFloat($('#pvalue1').val(), 10) * percentagereduce / 100; 
 $('#pvalue4').val(newvalue);         

 var takevalue1 = parseFloat($('#pvalue3').val(), 10);
 var takevalue2 = parseFloat($('#pvalue4').val(), 10);
 var finalvalue = takevalue1 - takevalue2;
 var finalvalue = parseFloat(finalvalue).toFixed(2)
 $('#pvalue5').val(finalvalue);   
});

无法使用javascript添加结果
