Question

我有以下代码，它往往会在单个输入表单中输入验证码。

该表单是角度应用程序注册过程的一部分，该应用程序将检查验证码与mySQL表中写入的验证码相同。

在验证之前有一个前一个表单，它有多个输入（名字，姓氏，电话和密码），下一个按钮进入验证过程。

所有网页元素都已成功找到，注册功能正在使用q按顺序执行所有操作。

以下是代码：

.then(function() {
  return signupModalButton.click(); // The next button on the first form
})

.then(function() {
  return common.waitForElementToBeVisible(signupModalCode); // Wait for the code input to be visible
})

.then(function() {
  return getVerificationCodeFromDatabase(phoneUsed); // Read the code from mySQL database
})

.then(function(code) {

  console.log('Got verification code: ' + code); // Logs correctly
  signupModalCode.sendKeys(code); // No keys get sent to the text box event if I change this to:
  //signupModalCode.sendKeys('test');

  browser.wait(function() {
    var ec = protractor.ExpectedConditions;
    return ec.textToBePresentInElement(signupModalCode);
  }, config.WAITING_TIMEOUT); // Same output with or without this browser.wait

  signupModalCode.getText().then(function(text) {
    console.log('text inside element: ' + text);
  }) // Nothing gets logged

  console.log('Entered code...'); // Gets logged!
  return signupModalButton.click(); // Doesn't happen
})

.then(function() { // Code doesn't reach here
  console.log('Promise resolved...'); // Doesn't get logged
})

当测试运行时，我可以看到文本框但是我看到没有文本输入，然后浏览器关闭，控制台中会出现以下错误：

我无法弄清楚访问这个文本框有什么问题，以及量角器如何跳过与该文本框相关的问题。

任何帮助都将不胜感激。

我认为您必须嵌套回调：

.then(function() {
  return signupModalButton.click().then(function() {
    return common.waitForElementToBeVisible(signupModalCode).then(function() {
      return getVerificationCodeFromDatabase(phoneUsed).then(function(code) {
        // etc...
      });
    });
  });
});

或者，不要明确解决承诺，让Control Flow处理它。

量角器sendKeys不会向文本框发送任何内容
