Handle selection p-checkbox with the same group - html

Question

I have a list like below:
rows: any[] = [{"id":"1721079361", "type":"0002", "number":"2100074912"},
{"id":"1721079363", "type":"0003", "number":"2100074913"},
{"id":"1721079363", "type":"0004", "number":"2100074914"},
{"id":"1721079361", "type":"0001", "number":"2100074911"}];
I want to load on the table with the checkbox.
The user only selects the items which have the same Id.
Here is HTML
<p-table [value]="rows">
<ng-template pTemplate="header">
<tr>
<td>
</td>
<th>ID</th>
<th>Type</th>
<th>Number</th>
</tr>
</ng-template>
<ng-template pTemplate="body" let-row>
<tr [pSelectableRow]="row">
<td>
<p-checkbox [(ngModel)]="selectedValues" value="{{row.id}}"></p-checkbox>
</td>
<td>{{row.id}}</td>
<td>{{row.type}}</td>
<td>{{row.number}}</td>
</tr>
</ng-template>
</p-table>
Test : {{selectedValues}}
But until now, I cannot find the solution for it. Pls advice

You can use disable property and bind it with row value, dynamically on change event of any checkbox.
component.html
<p-checkbox [disabled]="row && row.isDisable" [(ngModel)]="selectedValues" value={{row.id}}" (onChange)="updateList(selectedValues)" ></p-checkbox>
component.ts
updateList(val){
if(val.length === 0){
for(let i = 0; i<this.rows.length ;i++){
this.rows[i]['isDisable'] = false;
}
}else{
let id = val[0];
for(let i = 0; i<this.rows.length ;i++){
if(this.rows[i]['id']!== id){
this.rows[i]['isDisable'] = true;
}
}
}
}
Here is working code
Hope this solve your purpose!
