javascript - Seemingly inconsistent onstorage triggering in Safari -

I have encountered the following problem in Safari 5.0 (not all WebKit-based browsers), this code:

  & lt; Html & gt; & Lt; Script & gt; Var onstorage = function (evt) {warnings ([[evt.key, evt.oldValue, evt.newValue]. ('\ N')); } Var onclick = function (evt) {localStorage.setItem ('test', Math.random ()); } Var oninit = function () {// In fact, it works the same way with the old "plain event" onclick document .query selector ('# test'). AddEventListener ('click', onclick, false); Window.addEventListener ('storage', onstories, incorrect); } & Lt; / Script & gt; & Lt; Body onload = "oninit ()" & gt; & Lt; Input id = "test" type = "button" value = "set a random value" /> & Lt; / Body & gt;  

will trigger an alert if we click on the button while this code -

  & lt; Html & gt; & Lt; Script & gt; Var onstorage = function (evt) {warnings ([[evt.key, evt.oldValue, evt.newValue]. ('\ N')); } Var onclick = function (evt) {localStorage.setItem ('test', Math.random ()); } Var oninit = function () {window.addEventListener ('storage', onstorage, false); // In fact, it works similarly with the old "plain event" onclic document. Choir selector ('# test') AddEventListener ('click', onclick, falls); } & Lt; / Script & gt; & Lt; Body onload = "oninit ()" & gt; & Lt; Input id = "test" type = "button" value = "set a random value" /> & Lt; / Body & gt;  

triggers some alerts, as expected, I think this is a bug, but no one can explain to me - code in such a strange behavior Why the result of swapping two lines?
