Answer 2

This will do it. The timer is there for Chrome and Safari because in those browsers, the native browser behaviour that selects the whole element seems to trigger after the focus event, thereby overriding the effect of the selection code unless postponed until after the focus event:

var div = document.getElementById("editable");

div.onfocus = function() {
    window.setTimeout(function() {
        var sel, range;
        if (window.getSelection && document.createRange) {
            range = document.createRange();
            range.selectNodeContents(div);
            sel = window.getSelection();
            sel.removeAllRanges();
            sel.addRange(range);
        } else if (document.body.createTextRange) {
            range = document.body.createTextRange();
            range.moveToElementText(div);
            range.select();
        }
    }, 1);
};

The problem with focus event on a div is that it can't fire because it thinks a div should not be editable. Editable contents in the DOM are marked with tabindex in the background, so in order for your div to receive the onfocus event, you need to explicitly declare the div's tabindex property. HTML:

<div style=" border:solid 1px #D31444" contenteditable="true" tabindex="1" onfocus="document.execCommand('selectAll',false,null)" >12 some text...</div>

That should work with onfocus.
