jquery.validata.js plug-in collection, everything you want is here

Combined with the above, today I will write about how to use validate.

validate() validates the selected form.

validate method returns a Validator object. The Validator object has many methods that can be used to trigger validators or change the contents of the form.

Validate() options:

submitHandler: A function that is run after passing verification. The form submission function must be added to it, otherwise the form will not be submitted.

<br/>

$("#demoForm").validate({ onfocusout:false })

$("#demoForm").validate({ onkeyup:false })

<br/>onclick：类型 Boolean，默认 true，指定是否在鼠标点击时验证（一般验证 checkbox、radiobox）。<br/>

$("#demoForm")

).validate({ onclick:false })

$("#demoForm")

.validate({ focusInvalid:false })

<br/>focusCleanup：类型 Boolean，默认 false。当未通过验证的元素获得焦点时，移除错误提示（避免和 focusInvalid 一起使用）<br/>

$("#demoForm")

.validate({ focusCleanup:true })

<br/>errorClass：类型 String，默认 "error"。指定错误提示的 css 类名，可以自定义错误提示的样式。<br/>

$("#demoForm")
