<http://www.whatwg.org/specs/web-apps/current-work/multipage/timers.html#simple-dialogs> An optional callback parameter could be added to the simple dialogs API: > result = window.alert(message, [callback]); > > result = window.confirm(message, [callback]); > > result = window.prompt(message, [default], [callback]); If the callback argument is recognised as a function value: * the result is the supplied callback; * the callee returns without waiting for user input; * the callback is invoked after the dialog is dismissed. Otherwise [see current spec]: * the callee simply ignores the callback argument; * the script is paused until the dialog is dismissed; * the result is undefined, boolean, string or null. For user agents that don't support the updated API: > function promptWrapper(message, default, callback) { > var result = window.prompt(message, default, callback); > if (callback && (typeof callback === "function")) { > if (result !== callback) { > callback(result); > } > return callback; > } > return result; > } I'm not sure if navigator.yieldForStorageUpdates() is needed in the non-blocking mode.
