firstFields: Boolean|String[], 对于指定字段,遇见第一条未通过的校验规则时便调用callback回调,而不再校验该字段的其他规则 ,传入true代表所有字段。 Rules Rules 也可以是用于校验的函数 function(rule, value, callback, source, options) rule: 当前校验字段在 descriptor 中所对应的校验规则,其中的 field 属性...
firstFields: Boolean|String[], 当指定字段的第一个校验规则产生error时调用callback,不再继续处理相同字段的校验规则。true意味着所有字段生效。 Rules Rules 是执行校验的函数。 function(rule,value,callback,source,options) rule: 在源descriptor中,与要校验的字段名称相对应的校验规则。始终为它分配一个field属性...
