Tinymce 4.2.0 got Cannot read property 'setContent' of null

Question

I got Cannot read property \'setContent\' of null, when i want to using setContent function. Intended for set value in text editor generated by Tinymce library. Is am wrong

Answer 1

You have to wait until the editor is initialized:

tinymce.init({
  selector:'textarea',
  init_instance_callback : function(editor) {
    editor.setContent('custom');
  }
});
