Text selection in div(contenteditable) when double click

Question

I have div with some text and contenteditable="true". When I single click on this div - works some my scripts, it is not very important. And when I double click on this div - need to edit text in div. Edit text need to be only after double click, not after single. And very imortant, when I double click on div - caret need stay under mouse cursor. No need selection text. I found some script for single/double. But have problem. When I double click on div - text are selection. Selection no need. Need editor caret where I clicked. I do not understand how. http://jsfiddle.net/X6auM/

Single-click-to edit is the expected result for `contenteditable` element. If you want to use double-click, set the `contenteditable` *only* when the element is double-clicked. Once editable, focus to the element, then set the caret based on the mouse position from the double-click event. Finally, when focus is lost, disable the `contenteditable`. — Jay, Oct 16 '12 at 18:16
I do not understand how to place the cursor exactly at the place where there was a click. This with .focus(). But caret go to start of line. http://jsfiddle.net/jupUh/ — Alex-cr, Oct 16 '12 at 18:27
How can I find the position of caret if it has not been in div? — Alex-cr, Oct 16 '12 at 18:36
I found script which get caret position. Script works but not in this situation. http://jsfiddle.net/9Z3bp/1/ — Alex-cr, Oct 16 '12 at 19:18

Every current major browser provides an API to create a range from a mouse event, although there are four different code branches needed.

Here is some background:

Here's a demo: http://jsfiddle.net/timdown/krtTD/10/

And here's some code:

function getMouseEventCaretRange(evt) {
    var range, x = evt.clientX, y = evt.clientY;

    // Try the simple IE way first
    if (document.body.createTextRange) {
        range = document.body.createTextRange();
        range.moveToPoint(x, y);
    }

    else if (typeof document.createRange != "undefined") {
        // Try Mozilla's rangeOffset and rangeParent properties,
        // which are exactly what we want
        if (typeof evt.rangeParent != "undefined") {
            range = document.createRange();
            range.setStart(evt.rangeParent, evt.rangeOffset);
            range.collapse(true);
        }

        // Try the standards-based way next
        else if (document.caretPositionFromPoint) {
            var pos = document.caretPositionFromPoint(x, y);
            range = document.createRange();
            range.setStart(pos.offsetNode, pos.offset);
            range.collapse(true);
        }

        // Next, the WebKit way
        else if (document.caretRangeFromPoint) {
            range = document.caretRangeFromPoint(x, y);
        }
    }

    return range;
}

function selectRange(range) {
    if (range) {
        if (typeof range.select != "undefined") {
            range.select();
        } else if (typeof window.getSelection != "undefined") {
            var sel = window.getSelection();
            sel.removeAllRanges();
            sel.addRange(range);
        }
    }
}

document.getElementById("editor").ondblclick = function(evt) {
    evt = evt || window.event;
    this.contentEditable = true;
    this.focus();
    var caretRange = getMouseEventCaretRange(evt);

    // Set a timer to allow the selection to happen and the dust settle first
    window.setTimeout(function() {
        selectRange(caretRange);
    }, 10);
    return false;
};

It's amazing! Yesterday I made a few other methods. But does not work very well. Your version works fine. Thank you! — Alex-cr, Oct 17 '12 at 09:19
Doesn't work when element is inside the `#shadow-root` thingy. — izogfif, Aug 03 '23 at 23:47

$('p').dblclick(function(event) {
  $this = $(this);
  $this.attr('contenteditable', "true");
  $this.blur();
  $this.focus();
});

A suggestion, your answer would be complete if you explained what you were doing as well. – Rohit Gupta Jul 01 '15 at 11:48
