Answer 1

Utilisation du 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 
    } 
}); 

Plaine solution Javascript:

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"/>
