javascript - How do I get this "Share" button to grab the current URL's HTML title in addition to URL? -

-

I am trying to create the original share button in the form of a learning project. I'm stumped about a little bit of an aspect, while I can catch the URL of the current page and pass it in the URL which prepares the share form, I'm not sure how the HTML title can be increased.

What do I have to do here: 

  & lt; A href = "http://www.domain.com/submit" onclick = "window.location = 'http://www.domain.com/submit?url=' + encoder component (window location); return false ; "& Gt; It & lt; / A & gt; Share

To get the title of the current page, what do I add to the optical section? Whatever will be passed in the URL as "title =".

Bonus: Is there something that I can send some highlighted text from the current page? This URL will be known as "body ="

So I want to fill in these empty spots: 

   
 I think You want to receive the selected text is a bit more complicated, especially if you want to support IE is the standard DOM, but for IE you can find it The problem is a mess - I have not checked if things have improved in IE8. 
 
 Besides, I had to say that where the share button will be? If it is in the page, clicking on the button The selection of the text that is selected is selected.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
