Uncaught Reference Error: function is not defined
提问by scotter
I'm working on an app for webOS that will take a megaupload link(assuming its a video), parse it into a direct link and stream it to a ffplay port for webos called TouchPlay. I'm working on a basic prototype that will just take the end code on a megaupload link and return a direct link. Now that I have laid out the basic parts of my application, on to my question. I want to take data in a form in an html page and feed it into a function in an external js script. Here's the html portion
我正在为 webOS 开发一个应用程序，它将采用 megaupload 链接（假设它是一个视频），将其解析为直接链接并将其流式传输到名为 TouchPlay 的 webos 的 ffplay 端口。我正在研究一个基本的原型，它只会在 megaupload 链接上获取结束代码并返回一个直接链接。现在我已经列出了我的应用程序的基本部分，接下来是我的问题。我想在 html 页面的表单中获取数据，并将其提供给外部 js 脚本中的函数。这是html部分
<html>
<head>
<script LANGUAGE="JavaScript" src="source/main.js"></script>
</head>
<body>
<form NAME="myform" ACTION="" METHOD="GET">
Enter the MegaUpload Code, ex. megaupload.com/?d=glgrn8f1 -> glgrn8f1: <BR>
<INPUT TYPE="text" NAME="inputbox" VALUE="">
<INPUT TYPE="button" NAME="button" Value="Click" onClick="javascript:codeIn(this.form);">
</form>
</body>
</html>
And in my main.js file is in a subdirectory called source and it contains function codeIn(code){plus the rest of the functions.
在我的 main.js 文件中，它位于一个名为 source 的子目录中，它包含function codeIn(code){其他功能。
Yet when I enter some test data in my web page and hit submit, I get an error in the chrome dev console saying Uncaught Reference Error: codeIn is not defined
然而，当我在我的网页中输入一些测试数据并点击提交时，我在 chrome 开发控制台中收到一个错误说 Uncaught Reference Error: codeIn is not defined
I have a very limited experience with html and javascript, but I cant seem to figure this out, I imagine its something really simple that I'm missing.
我对 html 和 javascript 的经验非常有限，但我似乎无法弄清楚这一点，我想它是我遗漏的非常简单的东西。
EDIT: Here's main.js, and yes, I have checked for typos. Just ask if you need to see the contents of any of these functions, but I didn't think they were neccesary.
编辑：这是 main.js，是的，我检查了拼写错误。只是问您是否需要查看这些函数中的任何一个的内容，但我认为它们不是必需的。
function codeIn(code){
...
}
function getInfo(url){
...
}
function waiting(timer){
...
}
Ive looked through all these suggestions and it all seems to point to a syntax error, yet when I try to put all the js functions into the head of the html, it works. So thats what I'm doing. I don't change a single thing when I reference it from source/main.js, but whatever.
我查看了所有这些建议，似乎都指向语法错误，但是当我尝试将所有 js 函数放入 html 的头部时，它起作用了。所以这就是我正在做的。当我从 source/main.js 引用它时，我不会改变任何东西，但无论如何。

From the look of it, I think you then need to double check the location of main.js. Verify whether your HTML file is in a location from where main.js can be accessed as source/main.js, rather than something like ../source/main.js(in case your HTML file is in a folder parallel/sibling to the sourcefolder)
从它的外观来看，我认为您需要仔细检查main.js. 验证您的 HTML 文件是否位于可以作为 访问 main.js 的位置source/main.js，而不是类似的位置../source/main.js（如果您的 HTML 文件位于与该文件夹平行/同级的source文件夹中）

The RefereceError in general related to the scope of function that is present and the function call that is being made. It might the source path of the js, html/xhtml/jsp or function scope with in the js file. Hope this helps. Thanks.
RefereceError 通常与存在的函数范围和正在执行的函数调用有关。它可能是 js 文件中的 js、html/xhtml/jsp 或函数作用域的源路径。希望这可以帮助。谢谢。
