problem with Chrome form handling: input onfocus="this.select()"

If you really insist on sticking with onfocus, then you'll need to add onmouseup="return false" too.

Building on Jason's answer, here is a function that replaces the "select" function of DOM input nodes with an updated version that has the timeout built in:

if (/chrome/i.test(navigator.userAgent)) {
    HTMLInputElement.prototype.brokenSelectFunction = 
        HTMLInputElement.prototype.select;

    HTMLInputElement.prototype.select = function() {
        setTimeout(function(closureThis) { return function() {
            closureThis.brokenSelectFunction();
        }; }(this), 10);
    };
}

Basically, (in Chrome only) we just renamed the built-in but broken select() function to brokenSelectFunction() and then added a new function to all inputs called select() that calls brokenSelectFunction() after a delay. Now, just call select() normally, as the built-in select function has been replaced by the fixed function with Jason's delay suggestion.

This way, you don't have to worry about changing your existing calls to use a wrapper function (and once this is resolved in Chrome, you can just remove the above shim and go back to normal).

textbox.select(); // now runs select with setTimeout built-in (in Chrome only)

Edit: you might want to change the user-agent match from "chrome" to "webkit", as this issue happens in all webkit-browsers including Safari, and this fix will work for any of them.

Just use <input onmouseup=select()>. That works in all browsers.
