[Proposal] DOM onhighlighttext Event API

I suggest to add a new event in the Javascript DOM, namely onhighlighttext.

Example :

document.addEventListener("onhighlighttext", function(){
  alert("wow you highlighted me sir!");
});

Actually we can do this with getSelection by onmouseup or keyup , but it ends up with a syntax that is not neat and hard to read.

var t = "";
function gText(e) {
    t = (document.all) ? document.selection.createRange().text : document.getSelection();
    document.getElementById('input').value = t;
}

document.onmouseup = gText;
if (!document.all) document.captureEvents(Event.MOUSEUP);

Besides that we can use selectionchange, but selectionchange as the latter fires so many events (up to the chars selected), you have to wait some arbitrary period to get the final selection.

I can’t find any ideas and proposals about this.

Move from here

Looks like this is better discussed in the context of a new Issue for the CSS Custom Highlight API Module Level 1.
