如何獲取用$ _POST方法生成的Javascript值？

Question

我有三個文本框供應商的價格，標價和總價。 當我在供應商的價格和標註價格文本框中輸入值時，總價格文本框中的值將通過JavaScript生成一個值。

$('#sell_price, #markup_price').on('input',function() { 
    var sell_price = parseInt($('#sell_price').val()); 
    var markup_price = parseFloat($('#markup_price').val()); 
$('#total_price').val((sell_price + ((markup_price/100)*100) ? sell_price + ((markup_price/100)*100) : 0).toFixed(2)); 
}); 

如何將總價格的文本框值添加到我的$ _POST中？

HTML代碼

<div class="col-md-4"> 
    <label for="">Supplier's Price</label> 
    <div class="input-group"> 
     <span class="input-group-addon"> 
     ₱ 
     </span> 
     <input type="number" class="form-control" name="sell_price" id="sell_price" placeholder="Buying Price Per Unit" step='0.01' value='0.00' placeholder='0.00' required> 

    </div> 
    </div> 

    <div class="col-md-4"> 
    <label for="">Mark-up Price (In Percentage)</label> 
    <div class="input-group"> 
     <span class="input-group-addon"> 
     % 
     </span> 
     <input type="number" class="form-control" name="markup_price" id="markup_price" placeholder="0" required min='1' max='100'> 
    </div> 
    </div> 

     <div class="col-md-4">

     <div class="input-group"> 
      <span class="input-group-addon"> 
      % 
      </span> 
      <input type="number" class="form-control" name="total_price" id="total_price" placeholder="0" disabled> 
     </div> 
     </div> 

Answer 1

您可以路徑：

$('#total_price').val 

這樣：

function post(path, parameters) { 
var form = $('<form></form>'); 

form.attr("method", "post"); 
form.attr("action", path); 

$.each(parameters, function(key, value) { 
    var field = $('<input></input>'); 

    field.attr("type", "hidden"); 
    field.attr("name", key); 
    field.attr("value", value); 

    form.append(field); 
}); 

// The form needs to be a part of the document in 
// order for us to be able to submit it. 
$(document.body).append(form); 
form.submit(); 
}
