jquery.validate.js

jquery.validate.js使用记录

首先到JQ官网下载搜索validate插件，下载相关源码，附上validate官网网址

https://jqueryvalidation.org/

找到validation\demo\bootstrap，参考bootstrap与volidate结合使用的例子

改造成如上样式

如上所示，volidate能根据rules的规则当鼠标焦点离开输入框后，在输入框内添加OK或者X标志，并且生成文字节点添加指定DOM位置。是个挺不错的插件。

自定义规则以及提示信息：

 jQuery.validator.addMethod("url", function(value, element,params) {
      allow any non-whitespace characters as the host part
       return this.optional( element ) || /^\d{6}$/.test( value );
      }, '666');

需要注意的是：rules中 phoneNum， password，valid_code是input中name属性的值；

rules为教研规则，phoneNum为校验元素，required为校验方法，true为校验方法的参数；

messages:为校验错误是提示的字符串；

errorElement：追加错误信息时添加的标签

errorPlacement：错误信息追加到DOM

success：校验成功操作

highlight：添加成功样式

unhighlight：添加失败样式
