最新免费从github发布图片来自表单编辑发送图像密钥两次。
例如，使用下面的测试用例数据包含：
------WebKitFormBoundaryHjeY1fJPAaaXE56n
Content-Disposition: form-data; name="Pilt"; filename="eeva.bmp"
Content-Type: image/bmp
------WebKitFormBoundaryHjeY1fJPAaaXE56n
Content-Disposition: form-data; name="_image_Pilt"
------WebKitFormBoundaryHjeY1fJPAaaXE56n
Content-Disposition: form-data; name="Pilt"
请注意，name="Pilt"会出现两次。
要重现，请在Chrome中打开以下代码，选择行，启动表单编辑，选择一些图像，激活Chrome开发人员工具并按提交按钮。 请求有效负载显示已发布重复的Pilt密钥。
如何解决此问题，以便在早期版本中的帖子上没有重复的键？

答案 0 :(得分：1)
您使用useDataproxy选项。因此jqGrid根本不发送任何数据。如果存在某些问题，可能会出现在dataProxyAjax代码或jquery.form.js代码中。 jqGrid只是准备postdata对象中的数据。该对象仅包含一个名称为Pilt的属性。因此，与＃34;重复的任何问题形成关键职位＆＃34;可能不是免费jqGrid中的错误。
如果你想让那个免费的jqGrid使用与以前相同的输出字符编码，那么你只需要包含autoEncodeOnEdit: true jqGrid选项。此外，您可以使用serializeEditData。
更新：问题在于使用jQuery.val()来填充“添加/编辑”表单的所有字段。引入这些更改是为了支持HTML5输入元素具有新的类型值（number，color，range等等。由于副作用jqGrid填充了类型为image和file的字段。这是报道的问题的起源。
发布the commit后，问题应该得到解决。
