推荐答案
你只需要一个循环并创建一个新的每次迭代都是正方形。为了能够单独访问每个方块,每个生成的方块都有自己唯一的ID:
You just need a loop and create a new square on each iteration. In order to be able to access each square individually, each generated square gets its own unique id:
var cont = document.getElementById("container");
for(var i = 1; i <3001; ++i){
var div = document.createElement("div");
div.setAttribute("class", "square");
div.setAttribute("id", "div" + i);
var h1 = document.createElement("h1");
h1.textContent = i;
div.appendChild(h1);
cont.appendChild(div);
}
.square{
background:#fa5339;
color:#fff;
width:100px;
height:100px;
float:left;
border:1px solid #d63d26;
}
h1{
height: 50%;
width:100%;
display:flex;
align-items: center;
justify-content: center;
}
<div id=container>
</div>
