vue 表单 进阶 注意事项 校验


表单检验

在这里插入图片描述
注:prop对应的不单单是rules规则里面的验证项,同时对应着我们form-item下的v-model的值。prop绑定的类要与el-form-item下的v-model的值相对应。否则就算校验元素输入字符,也会提示“请输入”之类的提示语,造成校验不友好问题。
在这里插入图片描述

清除表单校验

// 清除表单校验的提示
if (this.$refs['XXX']) {
// 延时执行
this.$nextTick(function () {
this.$refs['XXX'].clearValidate();
})
};

callback()

vue表单自定义表单校验,不管检验是否通过一定要加 callback();

validateDatasourceNm(rule, value, callback) {
let reg = /^[+]{0,1}(\d+)$|^[+]{0,1}(\d+\.\d+)$/; //只允许输入正数
if (value === '') {
callback(); //这句话没有的话 会不知名的问题产生。
} else {
if (!reg.test(value)) {
callback(new Error(this.ruleNames[rule.fullField]));
}
callback();
}
}
