Using an ngModel for a column's select options


Using an ngModel for a column's select options



Using Angular, I have created a table where a user selects a number from each cell. I'd like to add up all the values for each column and display the sum. I could do this by creating an ngModelfor each select however this would result in a large number of ngModels and get confusing pretty fast.


ngModel


select


ngModels



Is there a better way of achieving this like using the same ngModel with different indexes or a similar method?


ngModel



I have attached a StackBlitz for this issue.

Check my StackBlitz. I just created an object with multiple indexes. Each index represent a select in the table. Then I use the changemethod the get the selected value and update my model.


change


this.models = {
'Alert':1,
'Poised':1,
'Patient':1,
'Diligent':1,
'Doing':1,
'Childlike':1,
'Experiencing':1,
'Diversifying':1,
'Reserved':1,
'Serious':1,
};

valueChange(event,index) {
this.models[index] = Number(event.target.value);
console.log(this.models);
}

<select [innerHtml]="dropdown | safeHTML" (change)="valueChange($event,'Alert')"></select>
