form 表单验证是异步问题记录

form 表单验证是异步的

const submit = () => {
    // 验证器A
    const validateA = () => {
        quotationSettingFormRefA.value.validate((valid: boolean) => {
            if (valid) {
                data.validA = true
            } else {
                data.validA = false
            }
            console.log(data.validA, 'validateA')
        })
    }

    // 验证器B
    const validateB = () => {
        quotationSettingFormRefB.value.validate((valid: boolean) => {
            if (valid) {
                data.validB = true
            } else {
                data.validB = false
            }
            console.log(data.validB, 'validateB')
        })
    }
    // 等待两个验证结束之后再进行提交
    Promise.all([validateA(), validateB()]).then(() => {
        console.log(data.validA, data.validB, 'valid')
	})
}

从截图可以发现是先执行了 then 里面的代码，然后再是验证器，说明form验证器是异步的，所以这种情况会影响提交，接着换另外一种方式

const submit = () => {
    const validateA = () => {
        return new Promise((resolve) => {
            quotationSettingFormRefA.value.validate((valid: boolean) => {
                if (valid) {
                    data.validA = true
                } else {
                    data.validA = false
                }
                resolve(valid)
                console.log(data.validA, '左边验证')
            })
        })
    }

    // 右边验证
    const validateB = () => {
        new Promise((resolve) => {
            quotationSettingFormRefB.value.validate((valid: boolean) => {
                if (valid) {
                    data.validB = true
                } else {
                    data.validB = false
                }
                resolve(valid)
                console.log(data.validB, '右边验证')
            })
        })
    }
    // 等待两个验证结束之后再进行提交
    Promise.all([validateA(), validateB()]).then((res) => {
        console.log(data.validA, data.validB, 'valid', res)
    })
}

Promise.all 和 Promise.allSettled 区别

Promise.allSettled([validateA(), validateB()]).then((res) => {
    console.log(data.validA, data.validB, 'valid', res)
})
