Select all text in a 'readonly' when it gains focus

Question

I've got a textbox (set to readonly) and I need its' contents to be selected for easy copy/paste when it gains focus. Using the code below it only seems to quickly select the text and then unselect it for some reason.

HTML

<input id='thing' type='text' value='some text' readonly='readonly' />

JavaScript

document.getElementById('thing').onfocus = function(){
    this.select();
};

The Fiddle works for me in Firefox. IE8 as well. What browser is not working for you? — Mike Christensen, Dec 14 '12 at 23:07
@John Yep, my bad. I guess i forgot to accept this one. I have now. — FiniteLooper, Mar 19 '15 at 20:27
@MikeChristensen the fiddle does not work for me on Chrome 45 — Sung Cho, Sep 18 '15 at 00:27
Hmm, strange, yes it no longer works for me in Chrome 45 either. Changing it to an `onclick` event does work for mouse clicks, but this means it will no longer work when the field is focused via keyboard navigation :/ — FiniteLooper, Sep 18 '15 at 12:04

This seems to be a work around:

<input id='thing' type='text' value='some text' onclick="this.select()" readonly='readonly' />

I guess the problem is that focus doesn't work correctly as the input is readonly.

You can now use CSS. With user-select: all; all text will be selected when a clicking on an element.

I like this a lot, just be aware that the _"all"_ option might be buggy in Safari, according to [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/user-select#Syntax). – jhaskell Jan 10 '17 at 02:34

does not work with `readonly` elments (just tested in Chrome 86) – Alex from Jitbit Nov 10 '20 at 16:04
