每当我单击按钮时，都会创建一个新的 div

Question

When the button is clicked, a new div is added. Each time it is clicked an additional div is added. The div have following properties:

1. It has a class box
2. For the text inside the div, number the div starting with 1.(Keep a counter variable to track what number comes next.)

I hope these pic might help you:

Answer 1

HTML:

<button onclick="newDiv()">Add Box</button>
<div id="parent"></div>

JS:

function newDiv() {
  var divElem = document.createElement("div");
    elementAttr.setAttribute('class','divclass');
//if you want to add text inside
    //var imText = document.createTextNode("Hello Wolrd");
   // divElem.appendChild(imText);
//you need a parent Div to put this inside
    var parent = document.getElementById("parent");
    parent.appendChild(divElem);}

just make a css class with a style that you want so when a div is made it will get a style.
