<input type="number" min="10" max="100" (keydown)="checkLength1($event,inputNumber)"#inputNumber/>
ts file
checkLength1(e: { key: string | number; keyCode: number; preventDefault: () => void; }, input: { value: string; }) {
const keyValue = e.key; const numberOnlyPattern = '[0-9] ';
const newValue = input.value (isNaN(keyValue) ? '' : keyValue.toString());
const match = newValue.match(numberOnlyPattern);
if ( newValue > 12 || !match || newValue === '') {e.preventDefault();} }
spec file
it("checkLength1", () => { const e ={ key: "1", keyCode: 1, preventDefault : () => void }
const input = {value:"1" }
component.onKeyPressHours(e, input); });
I am trying to write test cases for "checkLength1" method. But I am getting an error while constructing object for parameter "e". Please help me to resolve this
CodePudding user response:
Just replace void
with null
.
it("checkLength1", () => {
const e = { key: "1", keyCode: 1, preventDefault : () => null };
