将javascript函数链接到Submit按钮
[英]Link javascript function to Submit button
问题描述
This is the structure of my HTML: 
这是我的HTML的结构：
<html>
<body>
<head>
...
<script type='text/javascript' src="js/javascript.js"></script>
</head>
...
<button class="submit" onclick="submitted()">Submit</button>
</body>
</html>
My file directory is Desktop/Project/ . 我的文件目录是Desktop/Project/ 。 Within the project folder the HTML file is on its own and there is a subfolder called js where javascript.js exists. 在项目文件夹中，HTML文件是独立的，并且存在javascript.js的子文件夹js 。
Within the external js file it goes something like this: 在外部js文件中，它是这样的：
function submitted(){
...
subtask(variable)
...
}
function subtask(param){
...
}
Within submitted() I added alert('hello'); 在submitted()我添加了alert('hello'); as the first thing and it wouldn't trigger the alert when I refresh the html page. 作为第一件事，当我刷新html页面时，它不会触发警报。 Am I doing something wrong? 难道我做错了什么？

Change your <script> tag to: 将您的<script>标记更改为：
<script type="text/javascript" src="js/javascript.js"></script>
.. means "one directory above the current directory". ..表示“当前目录上方的一个目录”。

According to your descriptions, the html file is within project folder and the js file is within project/js folder, then the src path ../js/javascript.js must be wrong. 根据您的描述，html文件位于project文件夹中，而js文件位于project / js文件夹中，那么src路径../js/javascript.js必须错误。 Try js/javascript.js 试试js/javascript.js
Originally, I thought it was because you put your script tag within head , not after button tag. 最初，我认为这是因为您将script标签放在head内，而不是放在button标签后。 But I tried it. 但是我尝试了。 It works well with script in head 它的工作原理以及使用script在head
