How to load ace editor
I am trying to use the Ace code editor library (http://ace.ajax.org/), but im having trouble. According to the embedding guide, this should load the required js files from Amazons CDN.
<script src="http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/ace.js" type="text/javascript" charset="utf-8"></script>
However it fails, in Chromes console it shows:
Could not load worker ace.js:1
DOMException {message: "SecurityError: DOM Exception 18", name: "SecurityError", code: 18, stack: "Error: An attempt was made to break through the se…cloudfront.net/src-min-noconflict/ace.js:1:76296)", INDEX_SIZE_ERR: 1…}
ace.js:1
I also tried putting the ace library src-min folder locally and loading it with
<script src="/js/ace/ace.js" type="text/javascript" charset="utf-8"></script>
Which also failed with the errors:
Uncaught RangeError: Maximum call stack size exceeded
GET http://mysite/mode-javascript.js 404 (Not Found) 123f2c9_ace_1.js:1
GET http://mysite/notes/theme-monokai.js 404 (Not Found) 123f2c9_ace_1.js:1
Uncaught RangeError: Maximum call stack size exceeded
Lastly I tried loading all the js resources in the ace src-min folder, which also failed with errors :S
Answer
I can't paste all the code in the comment, so I'll start to answer your question by updating this one. This works fine for me:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>HTML</title>
<style>
#editor {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
}
</style>
</head>
<body>
<div id="editor">
function foo(items) {
var x = "All this is syntax highlighted";
return x;
}
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/ace/1.2.6/ace.js" type="text/javascript" charset="utf-8"></script>
<script>
var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.getSession().setMode("ace/mode/javascript");
</script>
</body>
</html>
Can you test this at your end and see if you still get the problems? If this code (singular) is ok it's probably that some other JavaScript affects ACE.
Here's a JSfiddle: http://jsfiddle.net/yDscY/. I get no errors in my Development Inspector.
I found the problem. If you have PHP or can do it with .htaccess. You have to send specific headers to comply to CORS (Cross Origin Resource Sharing).
access-control-allow-origin: *
access-control-allow-credentials: true
After that it should work.
Update
I didn't test this part thoroughly, but it should work.
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Credentials: "true"
</IfModule>
Good luck!
