How to operate hidden or invisible web elements in Selenium Webdriver using Java

Sometime We need to handle invisible or hidden web elements but Selenium WebDriver will only interact with visible elements, therefore the text of an invisible element will always be returned as an empty string. In some cases We need to operate like as click, get text, send value etc hidden web elements. The follow attribute use to hide web element.

style="Display:none;"

 <div class="owl-prev" style="display: none;">prev</div>  

style="Display:block;"

 <div data-easeout="bounceOutLeft" data-easein="bounceInRight" data-stop="7800" data-start="300" data-height="26" data-width="184" data-y="155" data-x="183" class="md-object md-layer-1-0-0 bounceInRight" style="width: 9.58333%; height: 5.97701%; top: 35.6322%; left: 9.53125%; display: block;">DO YOU NEED AN</div>  

style="visibility:hidden;"

 <div style="position: absolute; width: 9999px; visibility: hidden; display: none; max-width: none;"></div>  

type="hidden"

 <input type="hidden" value="form-w1cPBpyG9r-0a26cL3dRYB5fM-V6O_18Ojgef4qOoXo" name="form_build_id">

Clicking an invisible or hidden Element

 List<WebElement> number_of_display_none = driver.findElements(By.cssSelector("div[style*='none']"));  
 JavascriptExecutor executor = JavascriptExecutor)driver;  
 executor.executeScript("arguments[0].click();", number_of_display_none.get(position).getText());  

OR

 WebElement invisibleelement= driver.findElement(ElementLocator);  
 JavascriptExecutor executor = JavascriptExecutor)driver;  
 executor.executeScript("arguments[0].click();", invisibleelement);
