Question

我正在使用jQuery来获取表单的值并进行AJAX POST调用并将值发布到.php文件，该文件将值处理到db中。

每当我尝试使用alert()进行测试时，如果我得到了值，那么一切都有效，除了股票价值......我找不到我做错了什么..

jQuery的：

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);

表格：

<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>

此代码工作正常，我认为你没有从php / ajax获得价值..

为什么jQuery没有得到这个值？
