javascript - Check selection inside or outside of a class -

-

i have following lines of script selected area of document.

    sel = window.getselection();     console.log(sel);

i have results in console image below.

enter image description here

my question is,

is possible check selected text inside or outside of element specific class/id?

you can use anchornode (the node in selection begins) , focusnode (the node in selection ends) try determine whether or not selection in desired element.

assuming element you're interested direct parent of text being selected, can do:

var sel = document.getselection(); var startsintarget = sel.anchornode.parentelement.classlist.contains("target"); var endsintarget = sel.focusnode.parentelement.classlist.contains("target"); if(startsintarget && endsintarget) {      //selection within element class "target" }

here's jsfiddle demonstrating idea
