Javascript Question

disable TinyMCE text editor via Jquery

I ahave multiple Tiny MCE editors which I am trying to disable editing on. I have tried multiple variations of:

if(@Model.hasRegular.ToString().ToLower())
{
tinymce.get('#rte').getBody().setAttribute('contenteditable', false);
}
if(@Model.hasSmall.ToString().ToLower())
{
tinymce.get('#rteSmall').getBody().setAttribute('contenteditable', false);
}
if(@Model.isOneSize.ToString().ToLower())
{
tinymce.get('#rteOneSize').getBody().setAttribute('contenteditable', false);
}


with my editors all defined similarly like:

tinymce.init({
selector: '#rte',
toolbar: 'bold italic underline',
height: '200px',
width: '420px',
elementpath: false,
menubar: false,
content_style: "div {border: 50px solid red;}",

setup: function (ed) {
ed.on('init', function () {
this.getDoc().body.style.fontSize = '16px';
this.getDoc().body.style.fontFamily = 'Helvetica';
//disables editing for non admins
if ($('#nonAdmin').length) {
this.setMode('readonly');
}

});
}

});


currently with what I am trying, I am getting a console error:
Cannot read property 'getBody' of null

Answer

You have a typo in your disable code:

tinymce.get('#rte').getBody().setAttribute('contenteditable', false);

This line must be:

tinyMCE.get('rte').getBody().setAttribute('contenteditable', false);

So remove the # symbol.

Because you already used setMode you can do:

tinyMCE.get('rte').setMode('readonly');

or

tinyMCE.get('rte').setMode('code');

Snippet (fiddle: HERE):

$(function () {
  $('#nonAdmin').on('change', function(e) {
    tinyMCE.get('rte').getBody().setAttribute('contenteditable', !this.checked);
  });


  tinymce.init({
    selector: '#rte',
    toolbar: 'bold italic underline',
    height: '200px',
    width: '420px',
    elementpath: false,
    menubar: false,
    content_style: "div {border: 50px solid red;}",

    setup: function (ed) {
      ed.on('init', function () {
        this.getDoc().body.style.fontSize = '16px';
        this.getDoc().body.style.fontFamily = 'Helvetica';
        //disables editing for non admins
        if ($('#nonAdmin').prop('checked')) {
          this.setMode('readonly');
        }

      });
    }
  });
});
