Dojo 我的Dijit DateTimeCombo小部件在表单提交时不发送所选值

我需要创建一个Dojo小部件，让用户指定日期和时间。我发现一个示例实现附加到Dojo bug跟踪器中的一个条目上。它看起来不错，而且大部分都可以工作，但是当我提交表单时，客户端发送的值不是用户选择的值，而是从服务器发送的值

我需要做哪些更改才能让小部件提交日期和时间值

示例用法是使用基本HTML标记表单和输入呈现JSP，然后 加载一个函数，该函数通过ID选择基本元素，添加dojoType 属性，并dojo.parser.parse-es该页面

提前谢谢

小部件在两个文件中实现。该应用程序使用Dojo1.3

听起来你想使用getValue。现在的惯例是使用_getValueAttr，然后调用attrvalue，但我认为这是从Dojo1.4开始的，需要移植这段代码才能使用这些新模式

---

不，该值应该是一个Javascript日期对象，最好使用dojo.Date.stamp.toISOString将其发送到服务器。在我向DateTimeCombo.js添加了一个serialize方法后，该方法就可以正常工作了，该方法完全构建了我想要的输出格式

这对我来说似乎很奇怪，因为在_DateTimeTextBox.js中已经有一个序列化实现，它应该以所需的ISO格式输出值
