and my jQuery for Deductions is
我的 jQuery for Deductions 是

//计算扣除额。
function Deductions() {
var result = new Object();

remove the OnChange handler
删除 OnChange 处理程序
function Deductions() {
var result = new Object();
result.total = $("#Total").html();
result.totalDeductions = $("#txtTotalDeductions").val();
result.netTotal = result.total - result.totalDeductions;
$('#NetTotal').html(result.netTotal);
}
also wrap the code inside the ready handler and attach a change event handler
还将代码包装在就绪处理程序中并附加更改事件处理程序
$(document).ready(function(){
//attach with the id od deductions
$("#txtTotalDeductions").bind("change",Deductions);
});

Change your jScript to this, this will help :
将您的 jScript 更改为此，这将有所帮助：
$(function (){
$('#txtTotalDeductions').change(function (){
var total = $("#Total").html();
var totalDeductions = $("#txtTotalDeductions").val();
var netTotal = total - totalDeductions;
$('#NetTotal').html(netTotal);
});
});
you can also use object. i have removed it for my convinience.
你也可以使用对象。为了方便起见，我已将其删除。

编辑：
Remove your onchange event from textbox and also remove function deduction.
从文本框中删除您的 onchange 事件并删除函数推导。
