Typescript error: Property 'clear' or 'send' does not exist on type 'unknown' in protractor

Question

无法在使用打字稿的量角器中使用 clear 和 sendKeys。我是否缺少任何依赖项，因为即使单击也会引发错误？

我尝试了 Protractor clear() not working 的不同解决方案但 none 似乎有效

 async setEmail(username: String) {
        let emailField = await browser.wait(until.presenceOf(element(by.css("#username"))), DEFAULT_WAIT_TIME_SECONDS * 1000, 'Email field never appeared.');
     /* await emailField.clear().then(()=>{
           emailField.sendKeys(username);
       });*/
    emailField.clear();
    emailField.sendKeys(username);
       /* await emailField.sendKeys(protractor.Key.chord(protractor.Key.CONTROL, 'a'));
        await emailField.sendKeys(username);*/
    }

E/launcher - 错误：TSError：⨯ 无法编译 TypeScript： e2e/common/pageObjects/loginLogoutWorkflow/LoginPageEntities.ts(64,16)：错误 TS2339：属性 'clear' 在类型 'unknown' 上不存在。 e2e/common/pageObjects/loginLogoutWorkflow/LoginPageEntities.ts(65,17)：错误 TS2339：属性 'sendKeys' 在类型 'unknown' 上不存在。

Answer 1

这应该有效

async setEmail(username: String) {
  let emailField = element(by.css("#username"));
  await browser.wait(
    protractor.ExpectedConditions.presenceOf(emailField), 
    DEFAULT_WAIT_TIME_SECONDS * 1000, 
    'Email field never appeared.'
  );
  await emailField.clear();
  await emailField.sendKeys(username);
}

Answer 2

您也可以试试下面的代码片段。

async setEmail(username: String) {

var EC = browser.ExpectedConditions;
let emailField = element(by.css("#username"));


await browser.wait(EC.visibilityOf(emailField),10000);

await emailField.clear();
await emailField.sendKeys(username);
}
