【问题描述】:
我有一个formData 对象,其结构如下:
{
name: '',
defaultPort: 1000,
protocolPorts: [{
manual_ports: []
}]
}
manual_ports 是一个可以动态添加的字符串数组。对于每个这样的端口,我想用 Vuelidate 进行一些验证。
formData: {
name: { required, maxLength: maxLength(64) },
protocolPorts: {
$each: {
manual_ports: {
$each: {
required,
numeric,
maxLength: maxLength(5),
between: between(1, (Math.pow(2, 16) - 1)),
cantBeginWithZero,
cantBeDuplicate
}
}
}
}
}
最后一个验证是cantBeDuplicate - 我想检查当前编辑的端口是否与任何其他端口或defaultPort 重复。问题是它目前可以工作,但是它在每个端口文本字段下都显示错误,而不仅仅是在当前正在编辑的那个之后。有什么方法可以实现吗?
到目前为止,我已经尝试过:
function cantBeDuplicate (val) {
if (val) {
let ports = [...this.currentProtocol.manual_ports];
ports.splice(this.currentPortIndex, 1);
return this.currentProtocol.manual_ports.length > 1 ?
!ports.includes(val) :
+this.currentProtocol.manual_ports[this.currentPortIndex] === +this.currentProtocol['default_port'] || true;
} else {
return true;
}
}
...还有这个:
return val ?
(!_.initial(this.currentProtocol.manual_ports).includes(val) && +this.currentProtocol['default_port'] !== +val) : true;
这就是我的文本字段的定义方式(它们在 v-for 循环中):
<v-text-field
v-model="protocol['manual_ports'][index]"
:error-messages="portsErrors"
label="Port"
height="30"
single-line
flat
dense
required
@click="setCurrents(protocol, index)"
@blur="$v.formData.protocolPorts.$each[pi]['manual_ports'].$each[index].$touch()"
@input="$v.formData.protocolPorts.$each[pi]['manual_ports'].$each[index].$touch()" />
这是portsError 计算属性:
portsErrors() {
const errors = [];
if ( this.currentProtocol) {
const protocolIndex = findIndex(this.formData.protocolPorts, p => p.id === this.currentProtocol.id)
if (!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].$dirty) {
return errors;
}
!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].numeric && errors.push('Digits only')
!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].maxLength && errors.push('Max 5 digits')
!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].between && errors.push('Range: 1 - 65535')
!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].cantBeginWithZero && errors.push('No leading 0')
!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].cantBeDuplicate && errors.push('No duplicates')
!this.$v.formData.protocolPorts.$each[protocolIndex].manual_ports.$each[this.currentPortIndex].required && errors.push('Required')
}
return errors
},
是否可以只在当前编辑的端口下方显示错误信息?
