sendKeys to Textbox which you cannot Inspect (using Java)

I have this alert box with an textbox which cannot be inspected and in want to sendKeys to this textbot.
inspect absent
public void handleprompt() throws InterruptedException {
driver.get("http://www.tizag.com/javascriptT/javascriptprompt.php ");
driver.findElement(By.xpath("//input[#onclick='prompter()']")).click();
Thread.sleep(3000);
Alert prompt = driver.switchTo().alert();
prompt.sendKeys("abcd");
}
There is no error but the text is not visible in text box or my code is incorrect

Hai Bro there is nothing wrong with your code i just simply copy pasted your code and executed it it works absolutely fine
public void handleprompt() throws InterruptedException {
driver.get("http://www.tizag.com/javascriptT/javascriptprompt.php ");
driver.findElement(By.xpath("//input[#onclick='prompter()']")).click();
Thread.sleep(3000);
Alert prompt = driver.switchTo().alert();
prompt.sendKeys("abcd");
prompt.Accept();
}
After accepting the alert popup you are able to see the text you entered.

I removed the sleep (it's not a good practice) and instead added a wait for the Alert, sendKeys, and then accept. I noticed that I didn't see the text in the alert after sending but when the alert was accepted, it showed the "abcd" text.
public void handleprompt() throws InterruptedException {
String url = "http://www.tizag.com/javascriptT/javascriptprompt.php";
driver.get(url);
driver.findElement(By.xpath("//input[#onclick='prompter()']")).click();
Alert prompt = new WebDriverWait(driver, 10).until(ExpectedConditions.alertIsPresent());
prompt.sendKeys("abcd");
prompt.accept();
}
I tested this code and it's working.

How to handle intermittent alert in Selenium WebDriver?

I have automation scenario that sometimes the system return javascript alert and sometimes not at all. I don't know what the cause of this, probably the network issue. I already create the alert handler for this:
public boolean isAlertPresent() {
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.alertIsPresent());
return true;
}
I call this in one of my step that sometimes appear alert:
public WSSPage enterAndSearchContent(String title) throws InterruptedException {
waitForElementTextWithEnter(searchTextField, title);
while (isAlertPresent()){
Alert alert = driver.switchTo().alert();
alert.dismiss();
break;
}
return PageFactory.initElements(driver, WSSPage.class);
}
The problem is when the alert doesn't show up, it will give me NoAlertPresentException, and the automation result will be failed. I want the code to move on if the alert doesn't happen by moving to the next line, in this case it will just return PageFactory.initElements(driver, WSSPage.class);
Can you help me provide a better code from this?
Thanks a lot.

JavascriptExecutor worked for you. Just take care that you should execute it before clicking the event which invoke alert.
((JavascriptExecutor) driver).executeScript("window.confirm = function(msg) { return true; }");
Note :- do not use it after clicking on event which invoke alert confirmation box. Above code by default set the confirmation box as true means you are accepting/click on ok on all confirmation box on that page if invoked
Hope it will help you :)

You can modify the method isAlertPresent as given below and try it. It may help you.
public boolean isAlertPresent() {
try{
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.alertIsPresent());
return true;
}
catch (NoAlertPresentException noAlert) {
return false;
}
catch (TimeoutException timeOutEx){
return false;
}
}

You can include that particular exception in try catch. Then the exception will be catched and will not through any error and your execution will continue.
Also create a implicit wait to handle this with less timestamp.

click event seems sometime works and sometime doesn't work in selenium web driver

#Then ("^I hover on (.+) menu and (.+) submenu$")
public void mousehover(String elementName,String subMenu) throws InterruptedException{
Actions actions = new Actions(webdriver);
WebElement menuHoverLink = webdriver.findElement(By.xpath("//a[text() = '" + elementName + "']"));
actions.moveToElement(menuHoverLink).build().perform();
Thread.sleep(2000);
actions.moveToElement(menuHoverLink).moveToElement(webdriver.findElement(By.xpath("//a[text() = '" + subMenu + "']"))).click().build().perform();
System.out.println("Sub menu "+subMenu+" Has been clicked");
}
Blockquote Hi every one. This is my code to done mouse hover event and then click sub link. But most of the time sub link click event is working. But some time which is not works. The mouse hover event has been done. But sub link click event is not triggering. Really don't know why this happen. Thanks in advance..

I would try somethin like moving to where you want to click and then just clicking. With hover menus you can get some odd behaviour from selenium about when an elemenet is and isnt clickable. Try;
actions.MoveToElement(menuHoverLink).Perform();
//wait til clickable, you are sleeping, a wait til element is both displayed and enabled would be better - can explain more if needed
action.Click().Perform();
note: I think just using peform will build the action without explicitly stating
EDIT:
I would assume that sometimes it takes longer than the 2seconds sleep time for the the element to be clickable. What exception is thrown?
Instead of thread.sleep use a wait to decide if the element can be clicked, something like:
public void WaitForElementToBeClickable(IWebElement element)
{
var wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(10));
wait.Until<bool>((d) =>
{
if (IsElementDisplayed(element) && IsElementEnabled(element))
return true;
else return false;
});
}
public Boolean IsElementEnabled(IWebElement element)
{
try
{
return (element.Enabled);
}
catch (NoSuchElementException)
{
return false;
}
}
public Boolean IsElementDisplayed(IWebElement element)
{
try
{
return (element.Displayed);
}
catch (NoSuchElementException)
{
return false;
}
}

How to handle Javascript Alert/pop up window in selenium webdriver

I am not sure whether selenium webdriver can handle Javascript alert/pop-up window.
I have a scenario like
1. User uploads a xls file and click on upload button
2. Alert/Pop-up window will be displayed . Click "OK" on window
Am able to automate the above scenario but the Alert/pop-up window is displayed while running the scripts.
Is their anyway workaround that we can handle javascript alert/pop-up window?

You can also try waiting for the alert to appear and then accepting it.
Below is the code for that (after the upload button is clicked):
try{
//Wait 10 seconds till alert is present
WebDriverWait wait = new WebDriverWait(driver, 10);
Alert alert = wait.until(ExpectedConditions.alertIsPresent());
//Accepting alert.
alert.accept();
System.out.println("Accepted the alert successfully.");
}catch(Throwable e){
System.err.println("Error came while waiting for the alert popup. "+e.getMessage());
}

Switch to default content
Dismiss alert after accepting "OK"
Otherwise your alert is from a different window which you'll have to switch to in order to dismiss
driver.switchTo().alert().accept();
driver.switchTo().alert().dismiss();
driver.switchTo().alert().defaultConent();

Mock it out. Call javascript behind the UI directly:
WebDriver driver = new AnyDriverYouWant();
if (driver instanceof JavascriptExecutor) {
((JavascriptExecutor)driver).executeScript("yourScript();");
}

There are the four methods that we would be using along with the Alert interface:
void dismiss() – The dismiss() method clicks on the “Cancel” button as soon as the pop up window appears.
void accept() – The accept() method clicks on the “Ok” button as soon as the pop up window appears.
String getText() – The getText() method returns the text displayed on the alert box.
void sendKeys(String stringToSend) – The sendKeys() method enters the specified string pattern into the alert box.
if(isAlertPresent(ldriver)){
Alert alert = ldriver.switchTo().alert();
System.out.println(alert.getText());
alert.accept();
}

Alert is a interface which have the abstract methods below
void accept();
void dismiss();
String getText();
void sendKeys(String keysToSend);
new WebDriverWait(driver,10).
until(ExpectedConditions.alertIsPresent()).accept();
alertIsPresent() internally return the
driver.switchTo.alert(); then we don't have to write it explicitly
hope this is been helpful

selenium web driver - switch to parent window

I use selenium Web Driver. I have opened a parent window. After I click on the link the new window opens. I choose some value from the list and this window automatically closes. Now I need to operate in my parent window. How can I do this? I tried the following code:
String HandleBefore = driver.getWindowHandle();
driver.findElement(By.xpath("...")).click();
for (String Handle : driver.getWindowHandles()) {
driver.switchTo().window(Handle);}
driver.findElement(By.linkText("...")).click();
driver.switchTo().window(HandleBefore);
This does not work though.

Try this before you click the link that opens the new window:
parent_h = browser.current_window
# click on the link that opens a new window
handles = browser.window_handles # before the pop-up window closes
handles.remove(parent_h)
browser.switch_to_window(handles.pop())
# do stuff in the popup
# popup window closes
browser.switch_to_window(parent_h)
# and you're back

public boolean switchBackParentWindowTitle(String windowTitle){
boolean executedActionStatus = false;
try {
Thread.sleep(1000);
WebDriver popup = null;
Set<String> handles = null;
handles =driver.getWindowHandles();
Iterator<String> it = handles.iterator();
while (it.hasNext()){
String switchWin = it.next();
popup = driver.switchTo().window(switchWin);
System.out.println(popup.getTitle());
if(popup.getTitle().equalsIgnoreCase(windowTitle)){
log.info("Current switched window title is "+popup.getTitle());
log.info("Time taken to switch window is "+sw.elapsedTime());
executedActionStatus = true;
break;
}
else
log.info("WindowTitle does not found to switch over");
}
}
catch (Exception er) {
er.printStackTrace();
log.error("Ex: "+er);
}
return executedActionStatus;
}

This will not answer your question, however it might answer a similar one.
With SeleniumBase all you need to do is write:
self.switch_to_default_window()
And you're back to the parent window.
