I want to assign some value where the class name is "grid-filter" but it's giving a compilation error in the angular typescript.

code

document.getElementByClassName('grid-filter')[0].title='new title';

CodePudding user response：

You need to cast the element returned to an array of HTMLElement since you're selecting by class name:

(document.getElementByClassName('grid-filter') as HTMLElement[])[0].title = 'new title';
