Question

这可能只是一个简单的错误，但我花了最后3个小时试图解决它 - 没有成功。

我最终想要做的是使用输入的日期并将其与截止日期进行比较，以确定提交是否为时已晚。但是，目前为了简化目的，我只想告诉我日期已经改变，但没有成功。我在哪里错了？

$("#id_submission_date").datepicker({
    onSelect: function(dateText) {
        $("#late_submission_warning").text("Date selected");
    }
 });

以下是页面中的（缩短的）HTML：

好吧，似乎您的JavaScript存在某个问题，您必须查看控制台消息以查看出现了什么问题。

无论如何，我想在做出任何评论或完整解决方案之前看到完整的HTML和代码。但是根据您要求保持简单并且看到更改日期已被正确捕获的请求，我们必须遵循以下方法。

     $("#id_submission_date").datepicker({
        onSelect: function(dateText) {
         console.log(dateText);
        }
     });

这里是＆＃34; dateText＆＃34;应包含所需的选定日期。检查浏览器控制台。但是如果出现错误，将显示正确的错误。

获得适当的日期后，您可以进行比较。

如果出现错误，请在此处发布错误消息，我们可以进行更多讨论。
