nightwatchjs meta tag check if is not empty

Question

I would like to check if the description meta tag has any value but not sure how to do it.

Have tried this but no luck:

browser.verify.element("meta[name=description]").attribute('content').not.equals('');

any help appreciated, thanks!

Using the Selenium protocol "element" :

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

Plain Javascript solution:

if(document.querySelector("meta[name=description]")){

  if(document.querySelector("meta[name=description]").getAttribute("content") === "Description of the webpage")

    console.log("meta description with content 'Description of the webpage' found");
    // do something

}
else{

  console.log("meta description not found");
  // do something

}

<meta name="description" content="Description of the webpage"/>
