How can I validate some inputs that are not inside a form tag?
All the samples I found have a form tag, but I want to validate some inputs that are not inside a form.
回答1:
The previously accepted answer (since deleted) was linking to a plugin that was last updated in January 2009. This obsolete plugin is very different than the plugin the OP was asking about:
Title: "Validate inputs that are not inside a form with jQuery Validation plugin"
Tag: jquery-validate
Using the jQuery Validate plugin, you cannot validate input elements that are contained outside of a <form></form> container. There is no workaround for this limitation.
DEMO 1: Shows the proper usage with a form container.
<form id="myform">
<input type="text" name="myinput" />
<input type="submit" />
</form>

DEMO 2: Shows the form container changed into a div and the same code is now totally broken. The plugin does nothing without a form container.
<div id="myform">
<input type="text" name="myinput" />
<input type="submit" />
</div>

Your only alternative would be to use a different jQuery plugin for form validation. Unfortunately, I know of no jQuery form validation plugin that would allow you to validate input elements outside of a <form> container.

Provided we're talking about the same validation plug-in, I don't think it's possible.
I think the requirements for the plug-in dictate that the items to be validated are inside a form.
You could always try replacing the form with a div in a sample page...
