I have created a in HTML with required fields and then a Submit button with a ng-click=add().
The code is the following:
Enter name: <div class="mb-3">
<label class="form-label">Enter surname:</label>
<input type="text" class="form-control" placeholder="Person surname" ng-model= "newPerson.surname" required>
</div>
<div class="mb-3">
<label class="form-label">Enter age:</label>
<input type="text" class="form-control" placeholder="Person age" ng-model= "newPerson.age" required>
</div>
<div class="mb-3">
<label class="form-label">Enter occupation:</label>
<input type="text" class="form-control" placeholder="Person occupation" ng-model= "newPerson.occupation" required>
</div>
<button type="submit" class="btn btn-primary" ng-click="add()">Add</button>
</form>
When pressing the button, it adds the person and then it tells me that the fields are required but in my list the person is already there will undefined values.
I have declared on top of the document as well.
Thanks
You can as well use a validation method to validate the inputs on submission instead of required. example
public validateForm() {
if(newPerson.surname === null ||
newPerson.surname === undefined || newPerson.surname === " ")
{
error.surname = "Surname is required";
}
if(newPerson.age === null ||
newPerson.age === undefined || newPerson.age === " ")
{
error.age = "Age is required";
}
if(newPerson.occupation === null ||
newPerson.occupation === undefined || newPerson.occupation === " ")
{
error.occupation = "Occupation is required";
}
if(newPerson.surname !== null ||
newPerson.surname !== undefined || newPerson.surname !== " " ||
newPerson.age !== null ||
newPerson.age !== undefined || newPerson.age !== " " ||
newPerson.occupation !== null ||
newPerson.occupation !== undefined || newPerson.occupation !== "
)
{
this.add();
}
} <div class="mb-3">
<label class="form-label">Enter surname:</label>
<input type="text" class="form-control" placeholder="Person surname" ng-model= "newPerson.surname" required>
</div>
<span *ngIf="error.surname"> {{error.surname}}</span>
<div class="mb-3">
<label class="form-label">Enter age:</label>
<input type="text" class="form-control" placeholder="Person age" ng-model= "newPerson.age" required>
</div>
<span *ngIf="error.age"> {{error.age}}</span>
<div class="mb-3">
<label class="form-label">Enter occupation:</label>
<input type="text" class="form-control" placeholder="Person occupation" ng-model= "newPerson.occupation" required>
</div>
<span *ngIf="error.occupation"> {{error.occupation}}</span>
<button type="submit" class="btn btn-primary" ng-click="validateForm()">Add</button>
</form>
