jQuery 可以为 .class 的未来成员添加插件函数吗？

我不知道这是否可能，但这是我的问题：

我的 jQuery 应用程序动态添加了输入字段。例如，“添加新客户”按钮在当前表单之后添加一个新的输入表单。到目前为止，一切都很好！

但是，我发现自己需要将我想要的掩码函数添加到每个新创建的字段中，如下所示：

$("#customer_zipcode\\["+customerCount+"\\]).zipcodeMask(....);

zipcodeMask(...) 只是一个示例函数，用于检查以确保用户输入了正确的值邮政编码。其他类似的电话号码、信用卡等掩码。这部分效果很好，但我必须为每个新创建的元素设置它，我想要有一个邮政编码掩码。

我认为如果有像 .live() 这样的东西可以为邮政编码字段的每个未来实例执行 .zipcodeMask() 调用，那就太棒了。

我想我应该创建一个类，例如 "UseZipCodeMask"，并在每个需要邮政编码掩码的输入字段中执行类似 class="UseZipCodeMask" 的操作。

当我这样做时：

$(".UseZipCodeMask").zipcodeMask(....);

这对于具有此类的每个现有元素来说效果很好。如果我使用此类创建一个新字段，则它的 .zipcodeMask(...) 函数无法正常工作。

有没有办法让我的邮政编码字段自动设置 .zipcodeMask(...) ？它会稍微清理一下代码，每次创建一些新的输入字段时都会添加很多代码 .zipcodeMask() 和其他相关函数。

非常感谢！

Here's something I don't know if it's possible, but here's my question:

My jQuery application has dynamically added entry fields. For example, a button "Add New Customer" adds a new entry form after the current one. So far, so good!

However, I find myself needing to add the mask functions I want to every newly created field, like this:

$("#customer_zipcode\\["+customerCount+"\\]).zipcodeMask(....);

zipcodeMask(...) is just an example function that checks to make sure the user's entered a correct zip code. Other similar masks for phone numbers, credit cards, etc. This part works great, but I have to set it for every newly created element I want to have a zip code mask.

I thought it would be awesome if there was something like .live() that could do the .zipcodeMask() call for every future instance of the zip code field.

I thought I'd make a class, such as "UseZipCodeMask", and do something like class="UseZipCodeMask" in every input field that needs a zip code mask.

When I do this:

$(".UseZipCodeMask").zipcodeMask(....);

This works fine - for every existing element that has this class. If I create a new field with this class, it's doesn't have the .zipcodeMask(...) function working.

Is there a way to make my zip code fields get .zipcodeMask(...) automatically set for it? It would clean up the code a bit, there's a lot of code that adds .zipcodeMask() and other related functions every time some new input fields are created.

Thanks very much!
