I am new to Angular and primeng p-table. I am looking for a code snip or reference to know how to clear selected checkboxes to make all checkboxes to be unselected with code in Angular component.ts file when use primeng p-table.

CodePudding user response：

Assuming you have the selectionMode binding set to multiple, the selected data is binded to an array you declared in your component class. All you have to do is make a button “Clear” for example that empties that array.

//html
<p-table> … selectionMode=“multiple” [(selection)]=“selectedObjs” … </p-table>
<button (click)=“clearSelected()”>Clear</button>

//component
selectedObjs: {}[] = [];
…
clearSelected(): void {
this.selectedObjs = [];
}
