vue 表单验证 rule.message bug All In One
不使用 rule.message ✅
validateAmount (rule, value, callback) {
if (value === '') {
callback(new Error('请输入预算金额'));
} else if (value < this.amountValue || value > 9999999.99 || !Util.validAmount(value)) {
callback(new Error(`预算不少于${this.amountValue}元,不超过9999999.99元,仅支持最多2位小数`));
} else {
callback();
}
},
使用 rule.message ❌
budgetAmountValidate (rule, value, callback) {
const minValue = this.ruleForm.groupBudgetMode === 'BUDGET_MODE_DAY' ? 300 : 800;
const invalid = (value < minValue || value > 9999999.99 || !Util.validAmount(value));
if (value === '') {
callback(new Error(rule.message));
} else if (invalid) {
console.log('invalid', invalid);
const message = `预算不少于${minValue}元,不超过9999999.99元,仅支持最多2位小数`;
// rule.message 不更新
callback(new Error(message));
} else {
callback();
