Can Ace Editor support multiple code editors in one page?

Question

I'm looking to implement a web app that features "coding-competition"-styled interface with 2 different code editors in a single screen. One will be read only and the other will be active and would allow the user to edit.

I'm currently using Ace Editor and i find it awesome and simple to use.

However, here's my question. I seem to be getting an error upon trying to implement 2 different editors in a single page.

Uncaught RangeError: Maximum call stack size exceeded

Is the variable "editor" in the js script a restricted word or it doesn't matter what variable name is used?

Here's my code in my JS file:

var editorFirst = ace.edit("editorFirst");
var editorSecond= ace.edit("editorSecond");
setupEditor();

function setupEditor() {
    editorFirst.setTheme("ace/theme/eclipse");
    editorFirst.getSession().setMode("ace/mode/javascript");
    editorFirst.setShowPrintMargin(false);
    editorFirst.setHighlightActiveLine(true);
    editorFirst.resize();
    editorFirst.setBehavioursEnabled(true);
    editorFirst.getSession().setUseWrapMode(true);
    document.getElementById('editorFirst').style.fontSize = '14px';

    editorSecond.setTheme("ace/theme/eclipse");
    editorSecond.getSession().setMode("ace/mode/javascript");
    editorSecond.setShowPrintMargin(false);
    editorSecond.setHighlightActiveLine(true);
    editorSecond.resize();
    editorSecond.setBehavioursEnabled(true);
    editorReducer.getSession().setUseWrapMode(true);
    document.getElementById('editorSecond').style.fontSize = '14px';
}

Here's my code for the html file:

<script src="../assets/js/main.js"></script>
<script src="../assets/js/src/ace.js" type="text/javascript" charset="utf-8"></script>
<div id="editorFirst"></div>
<div id="editorSecond"></div>

Thanks in advance for the replies!

Answer 1

What I did was instead of using the id editor I set it as a class so code Then I just iterated every editor.

var editor;
$('.editor').each(function( index ) {
  editor = ace.edit(this);
  editor.getSession().setMode('ace/mode/csharp');
});

Ace can support any number of editors. The problem is recent regression which breaks resize for editors with height=0 see this demo
