当我使用 jQuery Mobile 1.3.0 设计 blobstore 上传表单 JSP 页面时，我遇到了一个非常不寻常的问题。我在下面发布代码。

<%@ page import="com.google.appengine.api.blobstore.BlobstoreServiceFactory"%>
<%@ page import="com.google.appengine.api.blobstore.BlobstoreService"%>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css" />
<link rel="stylesheet" href="/css/common.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
</head>
<body>
 <%
   BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();
 %>
 <form method="POST" action="<%=blobstoreService.createUploadUrl("/upload")%>"
  id="uploadImageForm" enctype="multipart/form-data">
    <label for="newsTitle">New Title</label>
    <input type="text" name="newsTitle" id="newsTitle" placeholder="Please enter some title" />
    <div style="clear: both; width: 100%;"></div>

    <label for="newsDescription">New Description</label>
    <textarea name="newsDescription" id="newsDescription" placeholder="Please enter some description" rows="10"></textarea>
    <div style="clear: both; width: 100%;"></div>

    <label for="newsPic">Choose Image (if any)</label>
    <input type="file" name="newsPic" id="newsPic" class="newsPic" />
    <div style="clear: both; width: 100%; height: 10px;"></div>

    <input type="submit" name="submit" data-role="button" data-inline="true" value="Submit" />
  </form>
</body>

当我尝试通过此表单将任何文件上传到 blobstore 时，出现此异常。

当我尝试使用普通的 css 和 jquery 库使用简单的 JSP 页面上传时，一切都工作得很好。

            <form method="POST"

                id="uploadImageForm" enctype="multipart/form-data">

                        style="height: 70px;"></textarea>
                    <div class="clear"></div>
                    <label for="newsPic">Choose Picture</label> <input type="file"
                        name="newsPic" id="newsPic" placeholder="Type some title..." />
                    <div class="clear"></div>
                    <input type="submit" class="btn btn-success" value="Submit" />
                </fieldset>
            </form>
        </div>
        <div class="span1"></div>
    </div>
</div>

根本无法理解为什么会出现这个问题。我需要你的建议。

最佳答案

也许问题与默认情况下 jQuery Mobile 使用 AJAX 提交表单有关。

为了能够在不使用 AJAX 的情况下提交表单，您可以通过添加 data-ajax=”false”数据属性为<form>标签。

我希望这会有所帮助。
