java - How do I find this element in Selenium (button on page to press)? -

i trying press "grid" class button on web page having trouble. here html:

<li id="prodlist" class="prodtab">     <span> products</span>         <div class="grid" onclick="gotoview('productgrid');"></div>         <div class="list" onclick="gotoview('productlist')"></div> </li> 

here tried gives org.openqa.selenium.nosuchelementexception:

driver.findelement(by.xpath("div[contains(@class, 'grid')]")).click(); 

the solution kind of problems either switch iframe, if element inside it:

webelement frame = driver.findelement(by.cssselector("iframe.ajaxstorenumberappendsrc")); driver.switchto().frame(frame);   // then, search element driver.findelement(by.xpath("//div[contains(@class, 'grid')]")).click(); 

or, make explicit wait wait element become present:

webdriverwait wait = new webdriverwait(webdriver, 5); wait.until(expectedconditions.presenceofelementlocated(by.xpath("//div[contains(@class, 'grid')]")));
