PrimeNG表验证 [英] PrimeNG table validation
问题描述
我正在关注PrimeNG表,这是StackBlitz演示.
从我的示例中,您可以看到第一行的类型为email的值无效,所有行均相同
您可以向用户显示某些值不正确,如下所示:
< ng-template pTemplate ="output">< p> {{rowData [col.field]}}</p>< p * ngIf ="rowData.propValueType.toLowerCase()=='电子邮件'&&!isCorrectEmail(rowData [col.field])style ="color:red">不正确的电子邮件</p></ng-template>
,然后在您的 .ts
文件中:
isCorrectEmail(emailAddress:any){让re =/^(([[^>()\ [\] \\.;;:\ s @] +(\.[^<>()\ [\] \\.,;:\ s @] +)*)|(".+))@((\ [[[0-9] {1,3} \.[0-9] {1,3} \.[0-9] {1,3} \.[0-9] {1,3} \])|(([[a-zA-Z \ -0-9] + \.)+ [a-zA-Z]{2,}))$/;返回re.test(String(emailAddress).toLowerCase());}
对于其他类型,您可以编写其他验证方法.
I've following PrimeNG Table Here is the StackBlitz demo.
https://stackblitz.com/edit/datatablevalidation
Only one column "Value" is editable.
In "Value" column, I want to add some validation based on the column "Type". I am rendering column value type dynamically
<input pInputText [(ngModel)]="rowData[col.field]" type={{rowData.propValueType.toLowerCase()}} class="form-control" />
My biggest challenge is validating the table on the first load because column Type is a new column feature of the existed product and data already existed in the table, i need to show all validation errors when a table is initiated.
From my sample, you can see that the first row is has type email has an invalid value , same for row all rows
You can show to user that some value is incorrect like this:
<ng-template pTemplate="output">
<p>{{rowData[col.field]}} </p>
<p *ngIf="rowData.propValueType.toLowerCase() =='email'
&& !isCorrectEmail(rowData[col.field])"
style="color:red">
incorrect email
</p>
</ng-template>
and then in your .ts
file:
isCorrectEmail(emailAddress: any) {
let re = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return re.test(String(emailAddress).toLowerCase());
}
For other types you can write other validation methods.
