jQuery Plugins/Validation 的option ignore

  在jQuery的官网上这样介绍jgnore：Elements to ignore when validating, simply filtering them out. jQuery's not-method is used, therefore everything that is accepted by not() can be passed as this option. Inputs of type submit and reset are always ignored, so are disabled elements.

 在初次使用ignore时，我希望通过ignore实现在每次发生focus和key事件时jQuery Validation可以自动忽略某个或某几个属性的验证，但是都没有成功。但是在submit时，validation却忽略了ignore属性的验证。由此可见，ignore是一个form级别的option，它只会在form submit时起作用。
