computed: {
    dataRule: function () {
        return {
            fCode: [/*三个验证不同的提示*/
                { required: true, message: this.$t('validate.required'), trigger: 'blur' },
                { pattern: /^[^\u4e00-\u9fa5]+$/, message: '不允许输入中文',trigger: 'blur'},

                { pattern: /[0-9a-zA-Z]{1,6}/, message: '只可以输入数字和字母',trigger: 'blur'},
                { min: 1, max: 6, message: '长度在 1 到 6个字符', trigger: 'blur' }
            ],
            fName: [
                { required: true, message: this.$t('validate.required'), trigger: 'blur' },
                { min: 1, max: 20, message: '长度在 1 到 20 个字符', trigger: 'blur' }
