Safari Extentions: Event for tab change? -

-

संभव डुप्लिकेट:

मैं सफ़ारी में एक पृष्ठ पर एक पॉपअप रखने की कोशिश कर रहा हूं जो टैब-विशिष्ट है, और एक बटन द्वारा ट्रिगर किया गया (जो स्पष्ट रूप से टॉगल हो सकता है)। मैं कैसे सुनिश्चित कर सकता हूं कि जब कोई टैब चालू हो जाए, तो बटन को सही ढंग से टॉगल किया जाएगा, अर्थात पॉपअप दिखाई देने पर प्रकाश डाला जाएगा; अन्यथा नहीं।

मैंने सुनने के लिए एक "टैब स्विच" प्रकार की घटना के लिए आस-पास देखा, लेकिन उसने काम नहीं किया और न ही फ़ोकस किया।

कोई विचार?

चीयर्स।

क्रोम के विपरीत जो खिड़की और टैब परिवर्तन की घटनाओं के लिए विशेष एपीआई प्रदान करता है, आप अब भी इसे सफारी एक्सटेंशन के साथ कर सकते हैं।

आपको अपने इन्सजेक्ट जावास्क्रिप्ट सेट ईवेंट श्रोताओं को उन घटनाओं के लिए रखना होगा जो आप चाहते हैं।

तब अगर उस जानकारी को वैश्विक या विस्तार के अन्य हिस्सों से जरूरी है, तो आप पोस्ट मेसेज कमांड का उपयोग करके जानकारी को संदेश में दे सकते हैं।

injected.js:

< P> window.addEventListener ("लोड", भरी हुई, झूठी);

सफारी। स्व। Tab.dispatchMessage ("कुछ हुआ हुआ", "लोड");

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .
