jQuery营业税

Question

I have created a function (see below) that calculates a 7.5% sales tax. 我创建了一个计算7.5％营业税的函数（请参见下文）。 Now I need help doing the following: 现在，我需要执行以下操作的帮助：

Have totalTax() take in 2 arguments one for the price and one for the tax. 让totalTax（）接受2个参数，一个作为价格，一个作为税收。
On submit (use the onSubmit event handler to call this function) have the function process the price and the tax by manipulating the arguments you passed in. 在提交时（使用onSubmit事件处理程序调用此函数），该函数通过处理传入的参数来处理价格和税款。
Have the sales tax on the page update dynamically with what ever the sales tax is that you defined for the function 7.5 percent sales tax: 使用为功能7.5％定义的销售税动态更新页面上的销售税：
Instead of using .innerHTML use jQuery to access these document elements and write to them: 而不是使用.innerHTML，而使用jQuery来访问这些文档元素并写入它们：
```
  document.getElementById('requestedAmount' ).innerHTML = priceInput; document.getElementById('requestedTax' ).innerHTML = salesTax; document.getElementById('requestedTotal' ).innerHTML = totalAmount; 
```

Original Code: 原始代码：

<script type="text/javascript">
$().ready(function() {
    // validate the comment form when it is submitted
    $("#inputForm").validate(); 
    $("#priceInput").priceFormat({
    prefix: '',
    limit: 5,
    centsLimit: 2
}); 
});

function totalTax(){
  var priceInput = document.getElementById( 'priceInput' ).value;
  var salesTax = Math.round(((priceInput / 100) * 7.5)*100)/100;
  var totalAmount = (priceInput*1) + (salesTax * 1);

  document.getElementById( 'requestedAmount' ).innerHTML = priceInput;
  document.getElementById( 'requestedTax' ).innerHTML = salesTax;
  document.getElementById( 'requestedTotal' ).innerHTML = totalAmount;
}
</script>

<body>
<form class="cmxform" id="inputForm" method="get" action="">
  <p>
    <label for="priceInput">Enter the price: </label>
    <input id="priceInput" name="name" class="required"/>
  </p>
  <p>
    <input class="submit" type="submit" value="Submit" onclick="totalTax();"/>
  </p>
</form>
<div>Entered price:
  <p id="requestedAmount"></p>
</div>
<div>7.5 percent sales tax:
  <p id="requestedTax"></p>
</div>
<div>Total:
  <p id="requestedTotal"> </p>
</div>

for your need of converting it to jquery is here: 您需要在这里将其转换为jquery：

$(document).ready(function() {
    // validate the comment form when it is submitted
    $("#inputForm").validate(); 
    $("#priceInput").priceFormat({
    prefix: '',
    limit: 5,
    centsLimit: 2
}); 
});

function totalTax(){
  var priceInput = parseFloat(($("#priceInput").var());//document.getElementById( 'priceInput' ).value;
  var salesTax = Math.round(((priceInput / 100) * 7.5)*100)/100;
  var totalAmount = (priceInput*1) + (salesTax * 1);

  $('#requestedAmount' ).html(priceInput) ;
  $( '#requestedTax' ).html(salesTax);
  $( '#requestedTotal' ).html(totalAmount);
}
</script>

<body>
<form class="cmxform" id="inputForm" method="get" action="">
  <p>
    <label for="priceInput">Enter the price: </label>
    <input id="priceInput" name="name" class="required"/>
  </p>
  <p>
    <input class="submit" type="submit" value="Submit" onclick="totalTax();"/>
  </p>
</form>
<div>Entered price:
  <p id="requestedAmount"></p>
</div>
<div>7.5 percent sales tax:
  <p id="requestedTax"></p>
</div>
<div>Total:
  <p id="requestedTotal"> </p>
</div>
