CodeMirror - load file on editor on page load

Question

I'd like to load inside the Codemirror editor a local file on page load, I've tried using FilerReader APIs without success. I also tried to use the jquery .load() function but I can only load a file in a generic textarea not in the editor.

Answer 1

On page load could wait for data request to complete before initializing codemirror

Since jQuery mentioned will use it for example

$(function(){
    $.get('path/to/codefile',  function(data){
          $('textarea#editorId').val(data);
          // now init codemirror 
    })

})
