使用JavaScript写入< div>的替代方法元件？

问题描述：

我想在页面加载时在页面的< div> 元素中打印出一条消息。我有以下HTML和JavaScript代码：

I want to print out a message in the page's <div> element upon page load. I have the following HTML and JavaScript code:

<body onload="printMsg()">
    <div id="write"></div>
</body>

function printMsg() {
    var node = document.getElementById("write");
    node.innerHTML = "<p>" + "Hello World!" + "</p>";
}

这里我用 onload 中的事件< body> 元素在页面加载时调用 printMsg（）。

Here I used onload event in <body> element to call printMsg() upon page load.

但如果我不使用 onload 事件，有没有其他方法可以写入< div id =write>< / div> 直接在JavaScript函数 printMsg（）？

But if I don't use onload event, is there any alternative way to write to <div id="write"></div> directly within the JavaScript function printMsg()?

答

正如Whipple建议你可以这样做：

as Whipple suggested you can do it as following :

   <body>
    <div id="write"></div>
    <script>
    (function printMsg() {
        var node = document.getElementById("write");
        node.innerHTML = "<p>" + "Hello World!" + "</p>";
    })();
    </script>
    </body>
