How to call external javascript on window.load?
提问by Wan
I want to put this in my website
我想把这个放在我的网站上
<script type="text/javascript"> <!-- window.onload = hello; function
hello() { var name = prompt("What is your name", "") alert ( "Hello "
+ name + "! Welcome to my forum.") } </script>
but I dont want to put it in index but in separate file, let say hello.js
但我不想把它放在索引中，而是放在单独的文件中，比如说 hello.js
How can I call it from index file so when I click the index.html, it will immediately prompt for my name. (for example)
如何从索引文件中调用它，以便当我单击 index.html 时，它会立即提示输入我的名字。（例如）
I put <script src="hello.js"></script>does not work.
我把<script src="hello.js"></script>不起作用。

Your hello.js should look something like this:
你的 hello.js 应该是这样的：
window.onload = hello;
function hello() {
var name = prompt("What is your name", "");
alert("Hello " + name + "! Welcome to my forum.");
}
and then the <script src="hello.js"></script>should work just fine.
然后<script src="hello.js"></script>应该可以正常工作。

There shouldn't be much more to it than importing that script. But then, your script is all broken. Of course it won't work, unless your browser can interpret it. Take a look at javascript basics. On the first look, you don't seem to be using semicolons to delimit individual statements. Also, you have opened an HTML comment <!--but you have never closed it...
应该没有比导入该脚本更多的内容了。但是，你的脚本全都坏了。当然它不会工作，除非您的浏览器可以解释它。看看javascript基础知识。乍一看，您似乎没有使用分号来分隔各个语句。此外，您打开了一个 HTML 注释，<!--但您从未关闭它...

Change your code to something like this:
将您的代码更改为如下所示：
<script type="text/javascript">
var name = prompt("What is your name", "");
alert ( "Hello " + name + "! Welcome to my forum."); </script>
i.e, remove any function and just write your alert directly, this should work.
即，删除任何功能并直接编写您的警报，这应该可以工作。
