[RESOLVED] Another ‘Can I …’ question

Copy linkTweet thisAlerts:
Jun 22.2009

Can I have a method to display the code of a JS function without saving the code in another text file and using ajax to read it?

I can envision saving an external JS file as TXT, but now I have two files maintain.
I want to display the code of the external file from the JS code itself.

Can I do this?

Alternatively, if the function is in the <HEAD> tag, can I display it within a <textarea> element?

@TheBearMayJun 22.2009 — Not sure how well it will validate, but:

[code=html]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript" id="myscript" >
if(window.attachEvent)
window.attachEvent("onload", showVal);
else
window.addEventListener("load", showVal, false);

function showVal() {
document.getElementById("oPut").innerHTML = document.getElementById("myscript").innerHTML;
}
</script>
</head>

<body>
<div>
<textarea id="oPut" style="width:80&#37;;height:10em"></textarea>
</div>
</body>
</html>[/code]

@svidgenJun 22.2009 — Sure.
[code=html]<html>
<head>
<script type='text/javascript'>
function loadCode() {
// test comment
document.getElementById('test').value = loadCode.toString();
}
</script>
</head>

<body>
<textarea id='test'>Your function code will be loaded here.</textarea>
<br /><input type='button' onClick='loadCode();' value='Load' />
</body>
</html>[/code]
IE7, FF3, and Chrome all display the function. IE7 and Chrome even show the comment.
