asp.net mvc - How does JSON work? If I do a jquery $.post with a return type of json, how does the data get returned? -

-

अगर मैं jquery से ऐसा पोस्ट करता हूं: 

  $। Post ("row / GetRowNames ", {currRow:" MyRow ", ऑफसेट: 3}, फ़ंक्शन (पंक्ति नाम) {/ मैं कैसे डेटा को व्याख्या कर सकता हूं}," जेसन ");

मैं डेटा पंक्ति नामों को कैसे परिभाषित करूं जो कि नियंत्रक में विधि से वापस पास हो? मुझे जेएसन परिणाम को तार की एक सरणी में बदलने की जरूरत है ...

यहां नियंत्रक विधि है जो पंक्ति नाम प्राप्त करती है: 

  [AcceptVerbs (HttpVerbs.Post )] सार्वजनिक JsonResult getRowNames (स्ट्रिंग currRow, int ऑफसेट) {यह लौटें। जेसन (_rowRepository.getRowNamesByOffset (currRow, ऑफ़सेट)); }

और getRowNamesByOffset (currRow, offset) स्ट्रिंग्स की एक सरणी देता है।

मुझे यकीन है कि कैसे जेसन काम करता है, क्या क्या यह सरणी को करने से पहले इसे जावास्क्रिप्ट पर वापस भेजता है? जावास्क्रिप्ट को जेएसओएन को कैसे आवश्यक डेटा प्राप्त करने के लिए हेरफेर करना चाहिए?

जावास्क्रिप्ट ऑब्जेक्ट नोडेशन (JSON) वापस कर दिया गया है और कॉलबैक को भेजा गया है: 

  फ़ंक्शन (पंक्तिनाम) {// पंक्ति नाम JavaScript का एक सरणी है जो किसी रो नाम का प्रतिनिधित्व करता है। // // फिर से पंक्ति नाम पर पुनरावृत्त करें आइए रो नाम के ऑब्जेक्ट को // एक टाइटिल प्रॉपर्टी है जिसे हम सतर्क करेंगे। के लिए (var i = 0; i & lt; rowNames.length; i ++) {अलर्ट (पंक्ति नाम [i]। टाइटल); }}

तो ध्यान देने योग्य बात यह है कि कॉलबैक में पैरामीटर एक JSON ऑब्जेक्ट है ... इस मामले में RowNames की एक श्रृंखलाबद्ध सरणी

आशा है कि यह मदद करता है!

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);

What is expire header and how to achive them in ASP.NET and PHP? -

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
