爲什麼jQuery沒有得到這個值？

Question

我正在使用jQuery來獲取表單的值，並進行AJAX POST調用並將值發佈到.php文件，該文件將值處理到數據庫中。

每當我試着用alert()測試，如果我得到的價值，一切正常，除了股票價值......我無法找到我在做什麼錯..

的jQuery：

var title = $("#title").val(); 
var text = $("#text").val(); 
var summary = $("#description").val(); 
var keywords = $("#keywords").val(); 
var price = $("#price").val(); 
var stock = $("#stock").val(); 
var brand = $("#brand").val(); 

var product = product; 

alert(title); 
alert(stock); 

形式：

<form class="form-horizontal form-inline"> 
      <div class="form-group"> 
       <label class="control-label col-sm-3" for="title">Product:</label> 
       <input type="text" class="form-control" id="title" name="title" placeholder="Enter new title"> 
      </div> 
      <div class="form-group"> 
       <label class="control-label col-sm-3" for="price">Price:</label> 
       <input type="text" class="form-control" id="price" name="price" placeholder="Enter new price"> 
      </div> 
      <div class="form-group"> 
       <label class="control-label col-sm-3" for="stock">Stock:</label> 
       <input type="text" class="form-control" id="stock" name="stock" placeholder="Enter new stock"> 
      </div> 
      <div class='form-group'> 
       <label class="control-label col-sm-3" for="text">Text:</label> 
       <textarea class='form-control' rows='5' id='text' name='text' placeholder='Enter new text'></textarea> 
      </div> 
      <div class="form-group"> 
       <label class="control-label col-sm-3" for="description">Description:</label> 
       <input type="text" class="form-control" id="description" name="description" placeholder="Enter new description"> 
      </div> 
      <div class="form-group"> 
       <label class="control-label col-sm-3" for="brand">Brand:</label> 
       <input type="text" class="form-control" id="brand" name="brand" placeholder="Enter new brand"> 
      </div> 
      <div class="form-group"> 
       <label class="control-label col-sm-3" for="keywords">Keywords:</label> 
       <input type="text" class="form-control" id="keywords" name="keywords" placeholder="Enter new keywords"> 
      </div> 
      <a href="#" id="updateProductRecord" pid="<?php echo $pro_id; ?>"><button type="submit" id="submitUpdateProduct" class="btn btn-default">Submit</button></a> 
      </form>

<form class="form-horizontal form-inline"> 
 
      <div class="form-group"> 
 
       <label class="control-label col-sm-3" for="title">Product:</label> 
 
       <input type="text" class="form-control" id="title" name="title" value="1" placeholder="Enter new title">

      </div> 
 
      <div class="form-group"> 
 
       <label class="control-label col-sm-3" for="description">Description:</label> 
 
       <input type="text" class="form-control" id="description" name="description" placeholder="Enter new description"> 
 
      </div> 
 
      <div class="form-group"> 
 
       <label class="control-label col-sm-3" for="brand">Brand:</label> 
 
       <input type="text" class="form-control" id="brand" name="brand" placeholder="Enter new brand"> 
 
      </div> 
 
      <div class="form-group"> 
 
       <label class="control-label col-sm-3" for="keywords">Keywords:</label> 
 
       <input type="text" class="form-control" id="keywords" name="keywords" placeholder="Enter new keywords"> 
 
      </div> 
 
      <a href="#" id="updateProductRecord" pid="<?php echo $pro_id; ?>"><button type="submit" id="submitUpdateProduct" class="btn btn-default">Submit</button></a> 
 
      </form> 
 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script> 
 
<script> 
 
var title = $("#title").val(); 
 
var text = $("#text").val(); 
 
var summary = $("#description").val(); 
 
var keywords = $("#keywords").val(); 
 
var price = $("#price").val(); 
 
var stock = $("#stock").val(); 
 
var brand = $("#brand").val(); 
 

 
var product = product; 
 

 
alert(title); 
 
alert(stock); 
 
</script> \t \t \t

此代碼工作正常，我認爲你沒有得到從PHP/AJAX ..值
