使用这个片段。

// Gets all elements with className 1 given in quotes and takes the first element of that list by using [0]
const divOne = document.getElementsByClassName("1")[0];
changeDisplayOnElement(divOne);
//Similarly
const divTwo = document.getElementsByClassName("2")[0];
changeDisplayOnElement(divTwo);

//change the property display under style to none, if it's block 

function changeDisplayOnElement(element){
   element.style.display = element.style.display === "none" ? "block" : "none";
}
