如何验证jquery .Validation（）中的动态datepicker？

Question

我正在尝试在数据库中插入动态datepicker。 一切正常！ 除了jquery .validation。 如果输入字段为空，请执行验证规则，例如，如果显示三则动态行，同时将其保留为空并按下提交按钮，则显示的验证消息为“请选择一个日期”，现在移到三行！

a）在第一行中，我选择了一个日期，然后按了提交按钮，在其余输入字段中显示“请选择一个日期”

b）接下来，我在第二个输入字段中选择了一个日期，然后按提交按钮。在这里需要做的是第三个输入字段显示验证消息，但日期选择器会自动在第二个输入字段中显示。 我不知道为什么在已经选择日期的第二个输入字段中自动显示日期选择器...

如果创建具有相同名称的输入将不起作用

<input type="text" name="date[]" />
<input type="text" name="date[]" />
<input type="text" name="date[]" />
<input type="text" name="date[]" />

代替这个

 <input type="text" name="date[0]" />
    <input type="text" name="date[1]" />
    <input type="text" name="date[2]" />
    <input type="text" name="date[3]" />

只需为每个输入添加索引

并在验证器中为dateField[]编写规则，或在输入标签中包含required属性。

我希望这能帮到您。
