JQuery Datepicker中的onSelect事件没有'似乎没有开火

onSelect event in JQuery Datepicker doesn't seem to fire

本文关键字：开火 onSelect 事件 Datepicker JQuery 中的      更新时间：2023-09-26

这可能只是一个简单的错误，但我花了最后3个小时试图弄清楚，但没有成功。

我最终想做的是使用输入的日期，并将其与截止日期进行比较，以判断提交是否为时已晚。然而，目前，为了简化起见，我只想告诉我，日期已经改变，但没有成功。我哪里错了？

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

以下是页面中的（缩短的）HTML：

您的JavaScript似乎有问题，您必须查看控制台消息才能发现问题所在。

无论如何，在发表任何评论或完整的解决方案之前，我希望看到完整的HTML和代码。但是，根据您的要求，为了保持简单，并确保正确记录更改的日期，我们必须遵循以下方法。

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

此处的"dateText"应包含所需的选定日期。请检查您的浏览器控制台。但是，如果出现错误，将显示正确的错误。

一旦确定了合适的日期，就可以进行比较

如果出现错误，请在这里发布错误消息，我们可以讨论更多。
