结合上面的,今天写一下validate的使用方法。
validate()验证所选的form。
validate 方法返回一个 Validator 对象。Validator 对象有很多方法可以用来引发校验程序或者改变 form 的内容。
validate()的可选项:
submitHandler:通过验证后运行的函数,里面要加上表单提交的函数,否则表单不会提交。

$("#demoForm")
).validate({ onclick:false })
<br/>focusInvalid:类型 Boolean,默认 true。提交表单后,未通过验证的表单(第一个或提交之前获得焦点的未通过验证的表单)会获得焦点。<br/>
$("#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")
.validate({ errorClass:"invalid" })
<br/>errorElement:类型 String,默认 "label"。指定使用什么标签标记错误。<br/>
$(".selector").validate errorElement:"em"})
<br/>highlight:可以给未通过验证的元素加效果、闪烁等。<br/><br/>
