JavascriptExecutor is not identifying the button to click in Webdriver

Question

I have this HTML

<div class="btnContr"> 
 <input type="button" onclick="return cancel();" value="Cancel"/>

Below is the xpath identified, using this xpath, I am not able to click on the button.

Xpath=//div[@class='btnContr']/input[@onclick='return cancel();']

Code written:

JavascriptExecutor jse = (JavascriptExecutor)ff;
 jse.executeScript("document.getElement(By.xpath('//div[@class='btnContr']/input[@onclick='return cancel();']').click()");

What should my code be?

• Anuragh27crony: Is this the only Input tag inside that Div or does it contain other Input elements too?
• Yash: Similar to Anuragh27's question- Are you sure the "btnContr" class name is unique?
• dzieciou: Cannot it be done simpler, without JavaScript? E.g., driver.findElement(By.css("input[value='Cancel']")).click()
• a Learner: there is no method like document.getElement(). It is document.getElementById(). For finding element by xpath using javascriptexecutor you have to use WebElement element=(WebElement)jse.executeScript("document.evaluate('xpath here')"). Check the syntax of evaluate. It also takes some more arguments.

Answer 1

The problem is in your use of quotes - they don't match correctly. Since you're using three levels of quotes (around document.getElement; around the xpath; and for the attributes) you'll need to escape one pair.

jse.executeScript("document.getElement(By.xpath(\"//div[@class='btnContr']/input[@onclick='return cancel();']\").click()");

• user6633: Tried your sollution. But still getting NullPointer Exception. It is as below java.lang.NullPointerException at com.lmm.ExcelLibrary.readExcelValue(ExcelLibrary.java:35) at com.lmm.Executor.testExecute(Executor.java:104) at OnFirefoxBrowser.LISTING_CANCEL.LISTING_CANCEL(LISTING_CANCEL.java:18) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source)
• dzieciou: This looks like a completely different problem, as NPE is thrown by ExcelLibrary,not WebDriver nor your code.

Answer 2

WebDriver driver; //instantiated somewhere else, obviously
WebElement element = driver.findElement(By.xpath("//div[@class='btnContr']/input[@value='Cancel']");
element.click();

Why are you bothering with JavascriptExecutor, when Selenium has the functionality to click an element selected by XPath built in?

Answer 3

I like to use below format to avoid quotes errors:

WebElement element= driver.findElement(By.xpath("//div[@class='btnContr']/input[@value='Cancel']"));
JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript("arguments[0].click();", element);

Answer 4

I was looking to click and send text by using xpath in JSE. Here is how I've done it:

WebElement element = driver.findElement(By.xpath("//input[@title='Search']"));
WebElement element1 = driver.findElement(By.xpath("//a[text()='Gmail']"));
String hi = "Hi";
JavascriptExecutor jse = (JavascriptExecutor) driver;
jse.executeScript("arguments[0].click();", element1); //for clicking
// for Entering text
jse.executeScript("arguments[0].value='"+hi+"';", element); 

Answer 5

This works for me:

WebElement elmnt =driver.findElement(By.xpath("//*[@id='signOutLink']")); 
JavascriptExecutor js = (JavascriptExecutor) driver; 
js.executeScript("arguments[0].click();", elmnt);

• IAmMilinPatel: Is this an answer to the question or is it just a thank you comment?
• Bharat Mane: This answer looks like a just copy paste of the above answer which was earlier answered by @Shubham Jain. If you have resolved your issue, just accept the answer rather than the new answer.
• corsiKa: The important part (the xpath) is different in this than in the other answer. Even if it was inspired by that answer as a jumping off point, it looks like the key part is different. I would contend (all else being equal) that this is an honest attempt at an answer.
