Hey there,
I'm a little confused with some Actionscript I'm working on. For my GUI, I have written four functions for times when computing is taking place. These are showMessage("Loading Text..."), disableButtons(), clearMessage(), and enableButtons(). They work great throughout the program. ShowMessage displays a loading message, disableButtons disables buttons so no one can click anything, clearMessage clears the loading message when job is done, and enableButtons turns them all back on.
For some reason, there is one button click handler which is giving me troubles and I'm not sure why. I've set it up just like others similar to it (which all work) but this one doesn't display the message or shut off my buttons. Here is my clickHandler...
private function Buffer_Route_clickHandler():void
{
showMessage("Loading RBE Options");
disableButtons();
if(Buffer_Route.selected && rbeAC.length == 0){
createRbeAC();
}
}
And here is the creatRbeAC function...
private function createRbeAC():void
{
rbeAC.removeAll();
hiddenRBELayers.removeAll();
var rbeIDs:Array = rbeConfigList.getKeySet();
for each (var rbeID:int in rbeIDs)
{
var rbeConfig:Hashtable = rbeConfigList.find(rbeID) as Hashtable;
var rbeData:Object =
{
restURL:rbeConfig.find("rbeRESTURL") as String,
layername:rbeConfig.find("rbeLayerName") as String,
icon: rbeConfig.find("rbeIcon") as String,
titlefield: rbeConfig.find("rbeTitleField") as String,
checked: rbeConfig.find("rbeChecked") as String,
count: "0" as String
};
if(rbeData.checked == "false")
{
hiddenRBELayers.addItem(rbeData.layername);// as String);
}
rbeAC.addItem(rbeData);
}
}
I wasn't getting any loading text, so I took out my clearMessage and enableButtons functions from the code to see if it was adding the message and disabling the buttons to begin with. I am still not getting anything though. Since clearMessage and enableButtons is no where to be found in this button click handler or creatRbeAC function, then I can not understand why the loading message and buttons aren't disabled, even when the computing is finished.
Some things to note. If I comment out the creatRbeAC function, the loading message shows and buttons do disable. Its almost as if those functions are being ignored when the creatRbeAC function is in the code.
Any help? I would greatly appreciate it. Hopefully I have provided enough information.
in my actual app, i have similiar problems.
In my Eventhandler (it doesn't matter, if there is a button handler or a mouse handler), I also wan't to disable the app and use some filter functions for my arrayCollection.
Unfortunately, this action seems to need too much ressources, especialy, when the app run in debug mode. I have to waint for the next screnn refresh. So i try to implement the "applyFilterMethod" in my eventhandler with
callLater(applyFilterMethod)
but it also wo't work.
Finally, the setTimeOut(applyFilterMethod,500)
solved my issue. So, try it with the timeout-method, if you have luck.

UPDATE: Google has recently updated their error message with an additional error code possibility: "timeout-or-duplicate".
This new error code seems to cover 99% of our previously mentioned mysterious
cases.
We are still left wondering why we get that many validation requests that are either timeouts or duplicates. Determinining this with certainty is likely to be impossible, but now I am just hoping that someone else has experienced something like it.
Disclaimer: I cross posted this to Google Groups, so apologies for spamming the ether for the ones of you who frequent both sites.
I am currently working on a page as part of a ASP.Net MVC application with a form that uses reCAPTCHA validation. The page currently has many daily users.
In my server side validation** of a reCAPTCHA response, for a while now, I have seen the case of the reCAPTCHA response having its success property set to false, but with an accompanying empty error code array.
Most of the requests pass validation, but some keep exhibiting this pattern.
So after doing some research online, I explored the two possible scenarios I could think of:
The validation has timed out and is no longer valid.
The user has already been validated using the response value, so they are rejected the second time.
After collecting data for a while, I have found that all cases of "Success: false, error codes: []" have either had the validation be rather old (ranging from 5 minutes to 10 days(!)), or it has been a case of a re-used response value, or sometimes a combination of the two.
Even after implementing client side prevention of double-clicking my submit-form button, a lot of double submits still seem to get through to the server side Google reCAPTCHA validation logic.
My data tells me that 1.6% (28) of all requests (1760) have failed with at least one of the above scenarios being true ("timeout" or "double submission").
Meanwhile, not a single request of the 1760 has failed where the error code array was not empty.
I just have a hard time imagining a practical use case where a ChallengeTimeStamp gets issued, and then after 10 days validation is attempted, server side.
My question is:
What could be the reason for a non-negligible percentage of all Google reCAPTCHA server side validation attempts to be either very old or a case of double submission?
**By "server side validation" I mean logic that looks like this:
public bool IsVerifiedUser(string captchaResponse, string endUserIp)
{
string apiUrl = ConfigurationManager.AppSettings["Google_Captcha_API"];
string secret = ConfigurationManager.AppSettings["Google_Captcha_SecretKey"];
using (var client = new HttpClient())
{
var parameters = new Dictionary<string, string>
{
{ "secret", secret },
{ "response", captchaResponse },
{ "remoteip", endUserIp },
};
var content = new FormUrlEncodedContent(parameters);
var response = client.PostAsync(apiUrl, content).Result;
var responseContent = response.Content.ReadAsStringAsync().Result;
GoogleCaptchaResponse googleCaptchaResponse = JsonConvert.DeserializeObject<GoogleCaptchaResponse>(responseContent);
if (googleCaptchaResponse.Success)
{
_dal.LogGoogleRecaptchaResponse(endUserIp, captchaResponse);
return true;
}
else
{
//Actual code ommitted
//Try to determine the cause of failure
//Look at googleCaptchaResponse.ErrorCodes array (this has been empty in all of the 28 cases of "success: false")
//Measure time between googleCaptchaResponse.ChallengeTimeStamp (which is UTC) and DateTime.UtcNow
//Check reCAPTCHAresponse against local database of previously used reCAPTCHAresponses to detect cases of double submission
return false;
}
}
}
Thank you in advance to anyone who has a clue and can perhaps shed some light on the subject.
You will get timeout-or-duplicate problem if your captcha is validated twice.
Save logs in a file in append mode and check if you are validating a Captcha twice.
Here is an example
$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response'])
file_put_contents( "logfile", $verifyResponse, FILE_APPEND );
Now read the content of logfile created above and check if captcha is verified twice
This is an interesting question, but it's going to be impossible to answer with any sort of certainly. I can give an educated guess about what's occurring.
As far as the old submissions go, that could simply be users leaving the page open in the browser and coming back later to finally submit. You can handle this scenario in a few different ways:
Set a meta refresh for the page, such that it will update itself after a defined period of time, and hopefully either get a new ReCAPTCHA validation code or at least prompt the user to verify the CAPTCHA again. However, this is less than ideal as it increases requests to your server and will blow out any work the user has done on the form. It's also very brute-force: it will simply refresh after a certain amount of time, regardless of whether the user is currently actively using the page or not.
Use a JavaScript timer to notify the user about the page timing out and then refresh. This is like #1, but with much more finesse. You can pop a warning dialog telling the user that they've left the page sitting too long and it will soon need to be refreshed, giving them time to finish up if they're actively using it. You can also check for user activity via events like onmousemove. If the user's not moving the mouse, it's very likely they aren't on the page.
Handle it server-side, by catching this scenario. I actually prefer this method the most as it's the most fluid, and honestly the easiest to achieve. When you get back success: false with no error codes, simply send the user back to the page, as if they had made a validation error in the form. Provide a message telling them that their CAPTCHA validation expired and they need to verify again. Then, all they have to do is verify and resubmit.
The double-submit issue is a perennial one that plagues all web developers. User behavior studies have shown that the vast majority occur because users have been trained to double-click icons, and as a result, think they need to double-click submit buttons as well. Some of it is impatience if something doesn't happen immediately on click. Regardless, the best thing you can do is implement JavaScript that disables the button on click, preventing a second click.
How can I let the user know when they are getting a hot code push?
At the moment the screen will go blank during the push, and the user will feel it's rather weird. I want to reassure them the app is updating.
Is there a hook or something which I can use?
Here's the shortest solution I've found so far that doesn't require external packages:
var ALERT_DELAY = 3000;
var needToShowAlert = true;
Reload._onMigrate(function (retry) {
if (needToShowAlert) {
console.log('going to reload in 3 seconds...');
needToShowAlert = false;
_.delay(retry, ALERT_DELAY);
return [false];
} else {
return [true];
}
});
You can just copy that into the client code of your app and change two things:
Replace the console.log with an alert modal or something informing the user that the screen is about to reload.
Replace ALERT_DELAY with some number of milliseconds that you think are appropriate for the user to read the modal from (1).
Other notes
I'd recommend watching this video on Evented Mind, which explains what's going on in a little more detail.
You can also read the comments in the reload source for further enlightenment.
I can image more complex reload logic, especially around deciding when to allow a reload. Also see this pacakge for one possible implementation.
You could send something on Meteor.startup() in your client-side code. I personally use Bert to toast messages.
I am new to firebase and I am having a bit of a nightmare trying to adapt old code to what is now deprecated and what is not. I am trying to write a function which updates one "single" record in my datasource using the now approved $save()promise but it is doing some really strange stuff to my data source.
My function (should) enables you to modify a single record then update the posts json array. However, instead of doing this, it deletes the whole datasource on the firebase server and it is lucky that I am only working with testdata at this point because everything would be gone.
$scope.update = function() {
var fb = new Firebase("https://mysource.firebaseio.com/Articles/" + $scope.postToUpdate.$id);
var article = $firebaseObject(ref);
article.$save({
Title: $scope.postToUpdate.Title,
Body: $scope.postToUpdate.Body
}).then(function(ref) {
$('#editModal').modal('hide');
console.log($scope.postToUpdate);
}, function(error) {
console.log("Error:", error);
});
}
Funnily enough I then get a warning in the console "after" I click the button:
Storing data using array indices in Firebase can result in unexpected behavior. See https://www.firebase.com/docs/web/guide/understanding-data.html#section-arrays-in-firebase for more information. Also note that you probably wanted $firebaseArray and not $firebaseObject.
(No shit?) I am assuming here that $save() is not the right call, so what is the equivalent of $routeParams/$firebase $update()to do a simple binding of the modified data and my source? I have been spending hours on this and really don't know what is the right solution.
Unless there's additional code that you've left out, your article $firebaseObject should most likely use the fb variable you created just before it.
var article = $firebaseObject(fb);
Additionally, the way in which you're using $save() is incorrect. You need to modify the properties on the $firebaseObject directly and then call $save() with no arguments. See the docs for more.
article.Title = $scope.postToUpdate.Title;
article.Body = $scope.postToUpdate.Body;
article.$save().then(...
I've been looking a bit at Selenium, and I'm beginning to like it, since I know some Java programming and find both Java and C# pretty straight-forward for simple things like this.
However, I'm struggling with a test that creates a new post in Wordpress, from the Dashboard page:
This is the Selenium code (in C#):
(The Driver instance is, obviously, a driver class I've created - for starting the browser and connecting to the wordpress site.)
1: Driver.Instance.FindElement(By.Id("title)).SendKeys(title);
2: Thread.Sleep(1000);
3:
4: Instance.SwitchTo().Frame("content_ifr");
5: Thread.Sleep(1000);
6:
7: Driver.Instance.SwitchTo().ActiveElement().SendKeys("something");
Now, what happens is that the title is easily found (by ID, so I wouldn't expect problems there), and I can easily insert the title text (line 1).
But the inline frame for the post body is causing problems. When running the test, after the topic is filled in, the cursor changes to the body area (line 4) - as planned. However, nothing more happens. The SendKeys("string") method (ine 7) doesn't seem to work there.
Any ideas?
EDIT: Of course - an important piece of information is that the iframe in Wordpress simply loads a TinyMCE editor. So, in the page source, there's only a body tag with the javascript loading of the editor.
EDIT2: Of course, something suddenly changed. Without ANY change to the wordpress page, the "content_ifr" is now suddenly missing (?!!!!!?) The Selenium test fails with "unable to locate frame...", and it's also suddenly missing from the page source.
EDIT3: I also noticed something:
Driver.Instance.SwitchTo().Frame(iframe);
Driver.Instance.FindElement(By.Id("tinymce")).SendKeys("message body");
It's the SECOND line that makes the cursor switch to the mce field, not the line with the .SwitchTo(). However, I need the first line - the second line does nothing on its own. This is approaching something really stupid. I've been looking for a solution to this for a week - this doesn't exactly bode well for Selenium. The Selenium user group doesn't even want to answer when I ask them.
Also - if I skip the SendKeys() method in the second line, nothing happens. So, it seems that the two lines does ALLMOST what it should, right up to and including placing the cursor in the correct spot. But it never sends any text.
EDIT4 (last): After actually figuring out how to use IJavaScriptExecutor, it works using the solution(s) below.
Java method to handle TinyMCE editor would look like:
public void entersTopicOfBody(String textToBeTyped, WebDriver driver) {
driver.switchTo().frame("content_ifr");
WebElement body = driver.findElement(By.xpath("//body"));
body.click();
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].innerHTML = '"+ textToBeTyped+"'", body);
driver.switchTo().defaultContent();
}
Below is some C# code that publishes a post. I think the main issues you have are due to timing issues.
I've done a bit of Selenium recently and I favour implicit waits: it waits for a maximum time period for the item to be available, but returns as soon as possible. So you can specify a max wait of 100 seconds, but if it finds it in 1 second, it will only wait 1 second. Much more efficient vs sleeping for an arbitrary length of time. See this post about Implicit and Explicit waits
But even with implicit waits, it may not solve all issues. When coding the sample below, I ran into the issue where the "Publish" button was disabled and re-enabled after some time. And that's when you have to look at the code to see what it is doing as well. It's times such as these where sleeps can help you fix the problem for a quick fix if you do not wish to debug too much: just be sure to set a large enough sleep time and be wary that it could be inconsistent in the future.

A PHP version of olyv solution:
$content = 'my text';
$this->frame( 'content_ifr' );
$body = $this->byXPath( '//body' );
$body->click();
$script = 'arguments[0].innerHTML = "" + arguments[1] + ""; ';
$this->execute( [
'script' => $script,
'args' => [ $body->toWebDriverObject(), $content ],
]
);
$this->frame( null );
I know that I am a bit late to the party, but I just found a solution that is (I believe) much simpler than the answers given so far. So I decided to post it here in case it could help someone else.
There is no need to switch frames here. What you wanna do is 'click' on the button in the top right corner of the text editor that says "Text", which has id = "content-html". Now, you can 'send keys" to the textarea, which has id = "content".
Here is some Python code that does just this:
driver.find_element_by_id("content-html").click()
driver.find_element_by_id("content").send_keys("Some text...")
Hope it helps
I'm still fairly new to ASP.Net, so forgive me if this is a stupid question.
On page load I'm displaying a progress meter after which I do a post back in order to handle the actual loading of the page. During the post back, based on certain criteria I'm disabling certain links on the page. However, the links won't disable. I noticed that if I force the links to disable the first time in (through debug) that the links disable just fine. However, I don't have the data I need at that time in order to make the decision to disable.
Code Behind
If (Not IsCallback) Then
pnlLoading.Visible = True
pnlQuote1.Visible = False
Else
pnlLoading.Visible = False
pnlQuote1.Visible = True
<Load data from DB and web service>
<Build page>
If (<Some Criteria>) Then
somelink.Disable = True
End If
End If
JavaScript
if (document.getElementById('pnlQuote1') === null) {
ob_post.post(null, 'PerformRating', ratingResult);
}
ob_post.post is an obout js function that does a normal postback and then follows up with a call to the server method named by the second param. then followed by the call to a JavaScript method named by the third param. The first parameter is the page to post back to. A value of null posts back to the current page.
The post back is working fine. All methods are called in the correct order. The code that gives me trouble is under the code behind in bold. (somelink.disabled = True does not actually disable the link) Again, if I debug and force the disabling of the link to happen the first time in, it disables. Does anyone know what I might do to get around this?
Thanks,
GRB
Your code example is using the IsCallBack check, while the question text talks about the IsPostback Check. I'd verify that you're using Page.IsPostBack in your code to turn off the links.
