Java Selenium的代码片段中没有“值”属性或文本时，如何使电子邮件/文本输入字段

Question

I want to Get the email id entered "arjun_123@gmail.com" using java code. I tried the below codes, but it always returned null.

What I really need is, I want to check whether email is successfully entered or not. Sometimes, email is not getting entered. So I want to check whether field is empty or not and retrieve the text entered.

email.getAttribute("innerText");
email.getAttribute("innerHTML");
email.getAttribute("textContent");
email.getText();

Answer 1

Pass your email xpath in this method. You will get entered text

    public String getTextofInputBox(By by) {

    JavascriptExecutor js = (JavascriptExecutor) driver; 
    String value = (String)((js).executeScript("return arguments[0].value",driver.findElement(by)));
    return value;
}

Answer 2

您拉回了错误的属性，您要使用的是值：

email.getAttribute("value");

Answer 3

<input> element

As per the documentation HTML <input> element is an interactive controls for HTML forms to accept data from the user.

Data validation

Data validation helps us to ensure that user have filled in the desired fields in the correct format to ensure that submitted data will be successfully accepted by the Application/Web Server.

As per the snapshot:

The <input> element contains JavaScript validation through the attribute data-validate which have 2 sub-validations as 'validate-email':true and 'required':true . These Javasript validations validates the text entered within the <input> field.

So once the Javasript validation completes you can extract the text you have entered in the EMAIL field ie arjun_123@gmail.com inducing WebDriverWait using the following solution:

System.out.println(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(email).getAttribute("value"));
