<body> <div class="elem1"></div> <div class="elem1"></div> <div class="elem2"></div> <div class="elem2"></div> <div class="elem1"></div> <div class="elem1"></div> </body> //so your code to count this should be like this var elementos = document.querySelectorAll(".elem1"); // then console.log(elementos.length); result should be 4 // in case you want to count the other elem2 // then you have to select (create another var elementos2 in this case) var elementos2 = document.querySelectorAll(".elem2"); console.log(elementos2.length); // the result will be 2 in this case remember that with query selector you got a node.list, not an array.

You can use jQuery for that here is an example: $('#main-div .specific-class').length Or you can also use vanilla js like: document.querySelectorAll('#main-div .specific-class').length;

Do it like this. <Body> <Div class="elem"></div> <Div class="elem"></div> <Div class="elem"></div> <Script> Var elem=document.getElementsByClassName("elem") Console.log=elem.length; </Script> </Body> Notice the script tags inside the body tags too

<Body> <Div class="elem"></div> <Div class="elem"></div> <Div class="elem"></div> <Script> Var elem=document.getElementsByClassName("elem"); Console.log(elem.length); </Script> </Body> Notice the script tags before closing the body
