How to add "Follow the link popup" into TinyMCE 4 - tinymce

Question

I implemented somethink like on this picture:
if you click on a link popup will appear and you can follow the link.

Answer 1

jQuery(function($){
/**
* add the follow link popup to all TinyMCE instances
*/
if (!window.tinymce) return;
tinymce.on('AddEditor', function( event ) {
tinymce.editors.forEach(function(editor) {
if (!editor.isFollowLinkAdded) {
editor.isFollowLinkAdded = true;
editor.on('blur', function(e) {
jQuery(e.target.contentDocument.body).find('#followLink').remove();
});
editor.on('click', function(e) {
var link = jQuery(e.target).closest('a');
jQuery(e.view.document.body).find('#followLink').remove();
if (link.length) {
e.preventDefault();
var POPUP_WIDTH = 215,
isRightSide = (jQuery(e.view.document).width()-e.pageX) >= POPUP_WIDTH,
boxCss = {
top: e.pageY,
padding: '6px 10px',
position: 'absolute',
backgroundColor: '#ffffff',
border: '1px solid #a8a8a8',
borderRadius: '2px',
boxShadow: '0 1px 3px rgba(0, 0, 0, 0.2)',
color: '#666666',
cursor: 'pointer',
whiteSpace: 'nowrap',
zIndex: 502
};
boxCss[(isRightSide) ? 'left' : 'right'] = (isRightSide) ? e.pageX : jQuery(e.view.document).width()-e.pageX;
jQuery('<a/>', {
href: link.attr('href'),
text: link.attr('href'),
target: '_blank'
}).css({
cursor: 'pointer',
display: 'inline-block',
maxWidth: '100px',
overflow: 'hidden',
textOverflow: 'ellipsis',
whiteSpace: 'nowrap'
}).wrap(
jQuery('<p/>', {
text: 'Click to follow: ',
id: 'followLink',
}).on('click', function(){
var win = window.open(link.attr('href'), '_blank');
win.focus();
}).css(boxCss)
).parent().appendTo(e.view.document.body);
}
});
}
});
}, true );
});

Answer 2

The most recent version of TinyMCE 4 (4.5.3) includes the option to open a link in the right click menu of the editor - no need to write your own custom code.
