打字稿错误：量角器中的类型 'unknown' 上不存在属性'clear'或'send'

Question

无法使用打字稿在量角器中使用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？

我尝试了量角器 clear(( 的不同解决方案不起作用 但似乎没有一个工作

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/启动器 - 错误： ⨯ 无法编译 TypeScript： e2e/common/pageObjects/loginLogoutWorkflow/LoginPageEntities.ts(64,16(：错误 TS2339：类型"未知"上不存在属性"clear"。 e2e/common/pageObjects/loginLogoutWorkflow/LoginPageEntities.ts(65,17(：错误 TS2339：类型"未知"上不存在属性"sendKeys"。

Answer 1

您也可以尝试下面的代码片段。

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);
}

Answer 2

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);
}
