如何在body标签后动态添加div到我的页面？

Question

我编写了以下代码，只是将它放在结束标记之前的div 我希望它在开头。

<script type="text/javascript" language="javascript">

        window.onload = function createDiv1() {
            var divTag1 = document.createElement("div");

            divTag1.id = "mid section";

            divTag1.setAttribute("align", "center");

            divTag1.className = "dynamicDivmid";

            divTag1.innerHTML = "pp";
            document.body.appendChild(divTag1);


        }

Answer 1

试试这样：

document.body.insertBefore(divTag1, document.body.firstChild)
