Is it possible to insert a variable as a parameter of startsWith()?-CodePudding

`<div >
    <div >
        <wcs-select [(ngModel)]="SelectedSerie" placeholder="Série" id="leselectg">
            <ng-container *ngFor="let serie of series">
            <wcs-select-option  *ngIf="serie.type_serie == 'Série'" >
                
                {{ serie.code_serie_materiel }}         
                
            
            </wcs-select-option>

                    {{ serie.code_serie_materiel }}         
                    {{ serie.type_serie }}

                    {{ serie.code_serie_materiel }}         
                    {{ serie.type_serie }}

I am trying to include a Selected Series variable in the parameters of my startsWith however it only works when I include a hard string, is there another way to include a variable?

CodePudding user response：

You can use string template literals, here is example:

const tmp = 'test';

console.log('testing string'.startsWith(`${tmp}`));
