|
|
*
|
|
* Why do it this way and not with TinyMCE's bookmarks?
|
|
*
|
|
* TinyMCE's bookmarks are very nice when working with selections and positions, BUT
|
|
* there is no way to determine the precise position of the bookmark when switching modes, since
|
|
* TinyMCE does some serialization of the content, to fix things like shortcodes, run plugins, prettify
|
|
* HTML code and so on. In this process, the bookmark markup gets lost.
|
|
*
|
|
* If we decide to hook right after the bookmark is added, we can see where the bookmark is in the raw HTML
|
|
* in TinyMCE. Unfortunately this state is before the serialization, so any visual markup in the content will
|
|
* throw off the positioning.
|
|
*
|
|
* To avoid this, we insert two custom `span`s that will serve as the markers at the beginning and end of the
|
|
* selection.
|
|
*
|
|
* Why not use TinyMCE's selection API or the DOM API to wrap the contents? Because if we do that, this creates
|
|
* a new node, which is inserted in the dom. Now this will be fine, if we worked with fixed selections to
|
|
* full nodes. Unfortunately in our case, the user can select whatever they like, which means that the
|
|
* selection may start in the middle of one node and end in the middle of a completely different one. If we
|
|
* wrap the selection in another node, this will create artifacts in the content.
|
|
*
|
|
* Using the method below, we insert the custom `span` nodes at the start and at the end of the selection.
|
|
* This helps us not break the content and also gives us the option to work with multi-node selections without
|
|
* breaking the markup.
