Nightwatchjs: how to check if element exists without creating an error/failure/exception

Question

In the page I\'m testing, two buttons may be displayed: BASIC or ADVANCED.

I want to be able to tell if the ADVANCED button is showing -- and if so, click it.

You can achieve this by using the Selenium protocol "element" and a callback function to check the result status to determine if the element was found. For example:

browser.element('css selector', '#advanced-search', function(result){
    if(result.status != -1){
        //Element exists, do something
    } else{
        //Element does not exist, do something else
    }
});
