I am trying to customize the behavior of an editor button in a plugin. On click, it opens a modal where the user can input some text. On confirmation, I want to wrap this text into code tags. But I don't want to take this text as if it comes from a text editor, I want to handle it as visual text. This means, I want to preserve any formatting (whitespaces and linebreaks) but not accept any other tags besides the code tags that I add afterward.
function showDialog() {
var win = ed.windowManager.open({
title: "Insert code",
body: {
type: 'textbox',
name: 'code',
multiline: true,
minWidth: ed.getParam("code_dialog_width", 600),
minHeight: ed.getParam("code_dialog_height", Math.min(tinymce.DOM.getViewPort().h - 200, 500)),
spellcheck: false,
style: 'direction: ltr; text-align: left'
},
onSubmit: function(e) {
ed.focus();
ed.undoManager.transact(function() {
ed.insertContent('<code>' + e.data.code + '</code>');
});
ed.selection.setCursorLocation();
ed.nodeChanged();
}
});
}
