javascript - Detect hover on selected text -

-

i building wysiwyg rich text editor.

when user selects portion of his/her text, present menu in tooltip. presenting menu works fine show if user hovers on selected text.

as illustrated:

enter image description here

i haven't decided on positioning (i way it's illustrated) clarify, that's not point of question.

the question is: how filter hover event happens on selected text?

the problems:

  1. i can't listen text selection event or test hover events see whether on elements have selected text inside them. left image generate false positive that.

  2. i know how selected text don't know how selected region.

to mind, the ideal solution somehow calculate region of selected text , test whether mouseover events happen in region.

on mouseup, use range.getclientrects grab bounding rectangles of each line of selection.

you can test if mouse on selection this:

var cr= [];  $(document).on({   'mouseup': function() {     cr= window.getselection().getrangeat(0).getclientrects();   },   'mousemove': function(ev) {     //hide pop     for(var = 0 ; < cr.length ; i++) {       if(ev.pagex >= cr[i].left && ev.pagex <= cr[i].right &&          ev.pagey >= cr[i].top  && ev.pagey <= cr[i].bottom         ) {         //show pop         break;       }     }   } });
