Automation script is not working?

This is the first time I get my hands on with automation instruments in xcode The script works well for all button taps but the one making server connection. I don't know the reason
Here is the script I tried so far
var target = UIATarget.localTarget();
target.pushTimeout(4);
target.popTimeout();
var window=target.frontMostApp().mainWindow()
var appScroll=window.scrollViews()[0];
appScroll.logElementTree();
UIATarget.localTarget().delay(2);
appScroll.buttons()[1].tap();
The above script works up to showing the UIActivityIndicator instead of moving to next controller after success
I know There must be a very simple point I am missing. So help me out

UIAutomation attempts to make things "easy" for the developer, but in doing so it can make things very confusing. It sounds like you're getting a reference to window, waiting for a button to appear, then executing .tap() on that button.
I see that you've already considered messing with target.pushTimeout(), which is related to your issue. The timeout system lets you do something that would be impossible in any sane system: get a reference to an element before it exists. I suspect that behind-the-scenes, UIAutomation repeatedly attempts to get the reference you want -- as long as the timeout will allow.
So, in the example you've posted, it's possible for this "feature" to actually hurt you.
var window=target.frontMostApp().mainWindow()
var appScroll=window.scrollViews()[0];
UIATarget.localTarget().delay(2);
appScroll.buttons()[1].tap();
What if the view changes during the 2-second delay? Your reference to target.frontMostApp().mainWindow.scrollViews()[0] may be invalid, or it may not point to the object you think you're pointing at.
We got around this in our Illuminator framework by forgetting about the timeout system altogether, and just manually re-evaluating a given reference until it actually returns something. We called it waitForChildExistence, but the functionality is basically as follows:
var myTimeout = 3; // how long we want to wait
// this function selects an element
// relative to a parent element (target) that we will pass in
var selectorFn = function (myTarget) {
var ret = myTarget.frontMostApp().mainWindow.scrollViews()[0];
// assert that ret exists, is visible, etc
return ret;
}
// re-evaluate our selector until we get something
var element = null;
var later = get_current_time() + myTimeout;
while (element === null && get_current_time() < later) {
try {
element = selectorFn(target);
} catch (e) {
// must not have worked
}
}
// check whether element is still null
// do something with element
For cases where there is a temporary progress dialog, this code will simply wait for it to disappear before successfully returning the element you want.

In my website www.theprinterdepo.com, you can view the page source, I have a code that my seo consulting suggested me to move to an external file.
Its an ecommerce site built on magento. ITs a free open source tool, so I did not developed it, I just installed it.
I need to know what the code does.
window.HDUSeed='c7025284683262a8eb81056c48968d74';
window.HDUSeedIntId = setInterval(function(){
if (document.observe) {
document.observe('dom:loaded', function(){
for (var i = 0; i < document.forms.length; i++) {
if (document.forms[i].getAttribute('action') && document.forms[i].getAttribute('action').match('contacts/index/post')) {
var el = document.createElement('input');
el.type = ('hidden');
el.name = 'hdu_seed';
el.value = window.HDUSeed;
document.forms[i].appendChild(el);
}
}
});
clearInterval(window.HDUSeedIntId)
}
}, 100);

In Brief
This script calls a function at an interval of every 100ms or so (as it's not guaranteed) to try to verify for the DOM's load status to add a hook on it.
If loaded, it then processes all the forms present in the page, looking for one with an "action" attribute (usually to submit it someplace, here contacts/index/post).
To all such forms found, it adds a new hidden input element containing "seed" value, but we cannot tell you what it is used for without knowing more about the codebase.
Detailed Code Review
// seed value, purpose unknown
window.HDUSeed='c7025284683262a8eb81056c48968d74';
// invoke this function every 100ms
// see: https://developer.mozilla.org/en/DOM/window.setInterval
window.HDUSeedIntId = setInterval(function(){
// checks if document.observe method exists (added by the Prototype
// JavaScript library, so we use this here to check its presence or
// that it's been already loaded)
if (document.observe) {
// hook on load status (when the page's DOM has finished loading)
// see: http://www.prototypejs.org/api/document/observe
document.observe('dom:loaded', function(){
// process all forms contained within the page's context
// see: https://developer.mozilla.org/en/DOM/document.forms
for (var i = 0; i < document.forms.length; i++) {
// only act on forms with the 'contacts/index/post/' action attribute
// see: https://developer.mozilla.org/en/DOM/document.forms
// and: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/match
if (document.forms[i].getAttribute('action') &&
document.forms[i].getAttribute('action').match('contacts/index/post')) {
// create an element...
// see: https://developer.mozilla.org/en/DOM/document.createElement
var el = document.createElement('input');
el.type = ('hidden'); // ... that is hidden
el.name = 'hdu_seed'; // w/ name 'hdu_seed'
el.value = window.HDUSeed; // and the seed value
document.forms[i].appendChild(el); // and add it to the end of the form
}
}
});
// Remove the interval to not call this stub again,
// as you've done what you want.
// To do this, you call clearInterval with the ID of the
// interval callback you created earlier.
// see: https://developer.mozilla.org/en/DOM/window.clearInterval
clearInterval(window.HDUSeedIntId)
}
}, 100); // 100ms

Looks like some sort of claification to an external thing. By this I mean services like Google Analytics. Remember if you are using any third party services for your website. If not I would recommend you delete it and see what happens. If it makes trouble or something, just restore the code back in your document.

The code looks for a form whose action is contacts/index/post and attempts to add a hidden field called 'hdu_seed'. It looks like an anti-spam measure, probably the server expects to receive this and if it doesn't exist, ignores it. This way, robots who aren't using javascript will not have this field included and probably the form will fail.
edit: it's actually not that complex at all.

Without know what the setInterval, clearInterval, and observe function do here is a rough outline of the logic
Call setInterval with a function and the integer 100
The function checks to see if the observe function has been loaded in this document
If it has then it calls the observe function with the dom:loaded parameter and a function and calls the clearInterval function, otherwise it does nothing
The inner function loops over every form in the document.
The loop checks the form for the action attribute.
If it exists and contains the string contacts/index/post then it creates a hidden input element with the name of hdu_seed and a value of window.HDUSeed
It then appends this element to the form.

using javascript to track another javascript script?

I was just wondering whether there are any way (libraries, frameworks, tutorials) to do javascript tracking with another script? Basically, i want to track as the user work with the site, which function gets executed with what parameters and so on, as detailed as possible.
thanks a lot!

The extent of detail you're expecting will be challenging for any solution to gather and report on without severely slowing down your scripts -- consider that, for every call, at least 1 other call would need to occur to gather this.
You'd be better to pick a few key events (mouse clicks, etc.) and track only a few details (such as time) for them. If you're using ajax, keep JavaScript and the browser oblivious and just track this on server-side.

There's a few options but I'm not sure if there are any "great" ones. I take it Firebug/IE Dev toolbar profiling won't work because you are trying to track remote user's actions.
So, one option (I'm not highly recommending for production purposes), will work in some but not all browsers.
Essentially you overwrite every function, with a wrapper that you then inject your logging.
(I haven't tested this, trying to recall it from memory... hopefully in "pseudo code" you get the idea...)
//e.g. get all functions defined on the global window object
function logAll(){
var funcs = [];
var oldFunc;
for(var i in window){
try {
if(typeof(window[i]) == 'function'){
if(i != 'logAll'){
funcs.push(i);
}
}
} catch(ex){
//handle as desired
}
}
var x;
for(var i in funcs){
x = '_' + new Date().getTime();
window[x] = window[i];//save the old function as new function
//redefine original
window[i] = function(){
//do your logging here...
//then call the real function (and pass all params along)
call(window[x]);
};
}
};

What's an effective way to move data from one open browser tab to another?

I am looking for a quick way to grab some data off of one Web page and throw it into another. I don't have access to the query string in the URL of the second page, so passing the data that way is not an option. Right now, I am using a Greasemonkey user script in tandem with a JS bookmarklet trigger: javascript:doIt();
// ==UserScript==
// #include public_site
// #include internal_site
// ==/UserScript==
if (document.location.host.match(internal_site)) {
var datum1 = GM_getValue("d1");
var datum2 = GM_getValue("d2");
}
unsafeWindow.doIt = function() {
if(document.location.host.match(public_site)) {
var d1 = innerHTML of page element 1;
var d2 = innerHTML of page element 2;
//Next two lines use setTimeout to bypass GM_setValue restriction
window.setTimeout(function() {GM_setValue("d1", d1);}, 0);
window.setTimeout(function() {GM_setValue("d2", d2);}, 0);
}
else if(document.location.host.match(internal_site)) {
document.getElementById("field1").value = datum1;
document.getElementById("field2").value = datum2;
}
}
While I am open to another method, I would prefer to stay with this basic model if possible, as this is just a small fraction of the code in doIt() which is used on several other pages, mostly to automate date-based form fills; people really like their "magic button."
The above code works, but there's an interruption to the workflow: In order for the user to know which page on the public site to grab data from, the internal page has to be opened first. Then, once the GM cookie is set from the public page, the internal page has to be reloaded to get the proper information into the internal page variables. I'm wondering if there's any way to GM_getValue() at bookmarklet-clicktime to prevent the need for a refresh. Thanks!

Can you move the bookmarklet to a button or link -- that Greasemonkey will add to the page(s)?
Then you could set click-event handlers to fire GM_getValue().
It looks like the current method is exploiting a "security hole" -- one that may be closed in the future. You might consider doing everything in a Firefox extension, instead.

How can I detect with JavaScript/jQuery if the user is currently active on the page?

I am needing to detect when a user is inactive (not clicking or typing) on the current page for more than 30 minutes.
I thinking it might be best to use event blubbling attached to the body tag and then just keep resetting a timer for 30 minutes, but I'm not exactly sure how to create this.
I have jQuery available, although I'm not sure how much of this will actually use jQuery.
Edit: I'm more needing to know if they are actively using the site, therefore clicking (changing fields or position within a field or selecting checkboxes/radios) or typing (in an input, textarea, etc). If they are in another tab or using another program, then my assumption is they are not using the site and therefore should be logged out (for security reasons).
Edit #2: So everyone is clear, this is not at all for determining if the user is logged in, authenticated or anything. Right now the server will log the user out if they don't make a page request within 30 minutes. This functionality to prevent the times when someone spends >30 minutes filling in a form and then submitting the form only to find out that they haven't been logged out. Therefore, this will be used in combination with the server site to determine if the user is inactive (not clicking or typing). Basically, the deal is that after 25 minutes of idle, they will be presented with a dialog to enter their password. If they don't within 5 minutes, the system automatically logs them out as well as the server's session is logged out (next time a page is accessed, as with most sites).
The Javascript is only used as a warning to user. If JavaScript is disabled, then they won't get the warning and (along with most of the site not working) they will be logged out next time they request a new page.

This is what I've come up with. It seems to work in most browsers, but I want to be sure it will work everywhere, all the time:
var timeoutTime = 1800000;
var timeoutTimer = setTimeout(ShowTimeOutWarning, timeoutTime);
$(document).ready(function() {
$('body').bind('mousedown keydown', function(event) {
clearTimeout(timeoutTimer);
timeoutTimer = setTimeout(ShowTimeOutWarning, timeoutTime);
});
});
Anyone see any problems?

Ifvisible.js is a crossbrowser lightweight solution that does just that. It can detect when the user switches to another tab and back to the current tab. It can also detect when the user goes idle and becomes active again. It's pretty flexible.

You can watch mouse movement, but that's about the best you're going to get for indication of a user still being there without listening to the click event. But there is no way for javascript to tell if it is the active tab or if the browser is even open. (well, you could get the width and height of the browser and that'd tell you if it was minimized)

I just recently did something like this, albeit using Prototype instead of JQuery, but I imagine the implementation would be roughly the same as long as JQuery supports custom events.
In a nutshell, IdleMonitor is a class that observes mouse and keyboard events (adjust accordingly for your needs). Every 30 seconds it resets the timer and broadcasts an state:idle event, unless it gets a mouse/key event, in which case it broadcasts a state:active event.
var IdleMonitor = Class.create({
debug: false,
idleInterval: 30000, // idle interval, in milliseconds
active: null,
initialize: function() {
document.observe("mousemove", this.sendActiveSignal.bind(this));
document.observe("keypress", this.sendActiveSignal.bind(this));
this.timer = setTimeout(this.sendIdleSignal.bind(this), this.idleInterval);
},
// use this to override the default idleInterval
useInterval: function(ii) {
this.idleInterval = ii;
clearTimeout(this.timer);
this.timer = setTimeout(this.sendIdleSignal.bind(this), ii);
},
sendIdleSignal: function(args) {
// console.log("state:idle");
document.fire('state:idle');
this.active = false;
clearTimeout(this.timer);
},
sendActiveSignal: function() {
if(!this.active){
// console.log("state:active");
document.fire('state:active');
this.active = true;
this.timer = setTimeout(this.sendIdleSignal.bind(this), this.idleInterval);
}
}
});
Then I just created another class that has the following somewhere in it:
Event.observe(document, 'state:idle', your-on-idle-functionality);
Event.observe(document, 'state:active', your-on-active-functionality)

Ifvisible is a nice JS lib to check user inactivity.
ifvisible.setIdleDuration(120); // Page will become idle after 120 seconds
ifvisible.on("idle", function(){
// do something
});

Using jQuery, you can easily watch mouse movement, and use it to set a variable indicating activity to true, then using vanilla javascript, you can check this variable every 30 minutes (or any other interval) to see if its true. If it's false, run your function or whatever.
Look up setTimeout and setInterval for doing the timing. You'll also probably have to run a function every minute or so to reset the variable to false.

Here my shot:
var lastActivityDateTime = null;
function checkActivity( )
{
var currentTime = new Date();
var diff = (lastActivityDateTime.getTime( ) - currentTime.getTime( ));
if ( diff >= 30*60*1000)
{
//user wasn't active;
...
}
setTimeout( 30*60*1000-diff, checkActivity);
}
setTimeout( 30*60*1000, checkActivity); // for first time we setup for 30 min.
// for each event define handler and inside update global timer
$( "body").live( "event_you_want_to_track", handler);
function handler()
{
lastActivityDateTime = new Date();
// rest of your code if needed.
}

If it's a security issue, doing this clientside with javascript is absolutely the wrong end of the pipe to be performing this check. The user could easily have javascript disabled: what does your application do then? What if the user closes their browser before the timeout. do they ever get logged out?
Most serverside frameworks have some kind of session timeout setting for logins. Just use that and save yourself the engineering work.
You can't rely on the assumption that people cannot log in without javascript, therefore the user has javascript. Such an assumption is no deterrent to any determined, or even modestly educated attacker.
Using javascript for this is like a security guard handing customers the key to the bank vault. The only way it works is on faith.
Please believe me when I say that using javascript in this way (and requiring javascript for logins!!) is an incredibly thick skulled way to engineer any kind of web app.

Without using JS, a simpler (and safer) way would simply be to have a lastActivity timestamp stored with the user's session and checking it on page load. Assuming you are using PHP (you can easily redo this code for another platform):
if(($_SESSION['lastAct'] + 1800) < time()) {
unset($_SESSION);
session_destroy();
header('Location: session_timeout_message.php');
exit;
}
$_SESSION['lastAct'] = time();
and add this in your page (optional, the user will be logged out regardless of if the page is refreshed or not (as he logs out on next page log)).
<meta http-equiv="refresh" content="1801;" />

You can add and remove classes to the document depending on the user active status.
// If the window is focused, a mouse wheel or touchmove event is detected
$(window).on('focus wheel touchmove', function() {
$( 'html' ).addClass('active').removeClass('inactive');
});
// If the window losses focus
$(window).on('blur', function() {
$( 'html' ).addClass('inactive').removeClass('active');
});
After that, you can check every while if the html has the "active" class and send an AJAX request to check the session status and perform the action you need:
setInterval( function() {
if ( $( 'html' ).hasClass('active') ) {
//Send ajax request to check the session
$.ajax({
//your parameters here
});
}
}, 60000 ); /* loops every minute */

If your concern is the lost of information for the user after a login timeout; another option would be to simply store all the posted information upon the opening of a new session (a new session will always be started when the older session has been closed/scrapped by the server) when the request to a page is made before re-routing to the logging page. If the user successfully login, then you can use this saved information to return the user back to where he was. This way, even if the user walk away a few hours, he can always return back to where he was after a successful login; without losing any information.
This require more work by the programmer but it's a great feature totally appreciated by the users. They especially appreciate the fact that they can fully concentrate about what they have to do without stressing out about potentially losing their information every 30 minutes or so.
