屬性列表

rules是表單校驗的規(guī)則列表，列表每一項表示一個字段的校驗規(guī)則，注意，必須要在Cell或Checkbox-group組件聲明prop屬性，表單校驗規(guī)則才生效，表單校驗規(guī)則的定義如下：

內(nèi)置校驗規(guī)則

接口

validate

validate接口接受類型為function的callback，callback有isValid和errors兩個參數(shù)，isValid表示是否校驗通過，errors在校驗失敗的時候的值為失敗的字段列表。

validateField

validateField接口接受2個參數(shù)， 第一個是字段名，第二個是類型為function的callback，callback有isValid和errors兩個參數(shù)，isValid表示是否校驗通過，errors在校驗失敗的時候的值為失敗的字段列表。
