jquery屏蔽输入插件，以便在出错时不清除字段 [英] jquery masked input plugin to not clear field when errored

问题描述

我在看 http://digitalbush.com/projects/masked-input -plugin /

我这样称呼它：

$(control).mask('999-999-9999');

如果出现问题，我不希望它丢弃用户输入，例如：他们还没有完成

And I don't want it to throw away the users input if something is wrong, e.g. they haven't finished

[407-555-____]

如果你输入这么多后离开现场，它会清除它。我想留下它以便以后完成。

If you leave the field after having typed this much, it clears it. I'd like to leave it so they can finish later.

我是jQuery的新手，我查看了他的来源，但我找不到任何方式做到这一点，我也找不到任何方法来编辑它来完成我想要的，因为代码对我来说是神秘的。

I'm new to jQuery, and I've looked through his source, but I can't find any way to do that, nor can I find any way to edit it to accomplish what I want, because the code is arcane to my eyes.

推荐答案

看起来我应该让整个面具可选：

It looks like I should just make the whole mask optional:

mask('?999-999-9999')

这样控件认为用户拥有的是有效，我可以继续。即使它不是面具的可选部分。

That way the control thinks what the user has is "valid" and I can continue. Even though it isn't really the optional part of the mask.
