Hi All, I have one field for amount. It will take only positive value and greater than 0. So, I need pattern validation for angular 7. "number" required #itemAmount= "ngModel" name= "itemAmount" [ class . is -invalid]= "itemAmount.invalid && itemAmount.touched" class = "form-control" [(ngModel)]= "appModel.itemAmount" placeholder= "Approval Limit" min= "1" />

Hi, You can try below pattern "number" required #itemAmount= "ngModel" name= "itemAmount" [ class . is -invalid]= "itemAmount.invalid && itemAmount.touched" class = "form-control" [(ngModel)]= "appModel.itemAmount" placeholder= "Approval Limit" min= "1" pattern= "^[1-9][0-9]*(\.[0-9]+)?|0+\.[0-9]*[1-9][0-9]*$" />

Hi All,

I have one field for amount. It will take only positive value and greater than 0.

So, I need pattern validation for angular 7.

<input type="number" required #itemAmount="ngModel" name="itemAmount" [class.is-invalid]="itemAmount.invalid && itemAmount.touched" class="form-control" [(ngModel)]="appModel.itemAmount" placeholder="Approval Limit" min="1"/>
