How can I locate an element using JavaScript in Selenium with C#?

Dealing with an outdated portal that requires the use of IE. There are certain elements, such as those within a <td> menu, that cannot be located. I attempted to locate them using XPath, but it was unsuccessful.

Upon further inspection, I discovered that the form is generated by a JavaScript function. I would like to trigger a click event in order to execute it, but how can I find the page elements using selenium WebDriver?

For instance, if I had the following code:

<div class="logout-link ng-scope" 
     ng-click="login(&quot;github&quot;)" 
     ng-show="!me" ng-controller="MenuCtrl">login</div>

How can I trigger the ng-click part using Selenium WebDriver?

Ensure that you are trying to locate the element in the correct frame. For more information, check out this example: How to switch between frames in Selenium WebDriver using Java
Consider waiting for the element to become visible and accessible. Visit: http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp
If you are familiar with finding elements using JavaScript (document.getElementsByClassName('logout-link ng-scope')), here's how you can execute JS in C#: Execute JavaScript using Selenium WebDriver in C#. The main difference is that instead of returning anything, you simply need to '.click()'

Is there a specific reason why you are using Javascript to locate an element? You may want to consider utilizing WebDriverWait to wait until the element is visible and clickable, as shown below:

var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));

var Login = wait.Until(ExpectedConditions.ElementToBeClickable(By.Xpath("//div[text() = 'login']")));
 Login.Click();

Please note: Ensure that the element is not located inside any frame before attempting this method.

I hope this solution proves to be helpful.

By simply clicking on the web element you have created, it triggers the associated function. To locate the element using CSS Selector and ng-click:

IWebElement elem = driver.FindElement(By.CssSelector("div[ng-click=login(&quot;github&quot;)]"));
elem.click();

Alternatively, you can create an action to move to the element and then click on it:

IWebElement elem = driver.FindElement(By.CssSelector("div[ng-click=login(&quot;github&quot;)]"));
Actions action = new Actions(driver);
action.MoveToElement(elem).Click().Build().Perform();
