How to merge two arrays in Javascript and de-duplicate items -

-

मेरे पास दो जावास्क्रिप्ट सरणियाँ हैं: 

  var array1 = ["विजेंद्र", "सिंह "]; Var सरणी 2 = ["सिंह", "शाक्य"];

मुझे आउटपुट होना चाहिए: 

  var array3 = ["विजेंद्र", "सिंह", "शाक्य"];

आउटपुट सरणी को दोहराए गए शब्द दोहराए जाने चाहिए।

मैं जावास्क्रिप्ट में दो सरणियों को कैसे मर्ज करूँगा ताकि मैं एक ही क्रम में प्रत्येक सरणी से अनन्य आइटम्स प्राप्त कर सकूं वे मूल सरणियों में डाली गई थीं?

बस सरणियों को मर्ज करने के लिए (डुप्लिकेट को हटाने के बिना) सरणी.संकेत : 

  var array1 = ["विजेंद्र", "सिंह"]; Var सरणी 2 = ["सिंह", "शाक्य"]; Var सरणी 3 = सरणी 1। संकल्प (array2); // डुप्लिकेट को निकालने के रास्ते में कोई 'बनाया' नहीं है (वास्तव में है) / / ['विजेंदर', 'सिंह', 'सिंह', 'शाक्य'] /  Array.forEach  जो इसके लिए बहुत अच्छा होगा ..), इसलिए हम इसे स्वयं करते हैं: 
 
  Array.prototype.unique = function () {var a = this .concat (); के लिए (var i = 0; i & lt; a.length; ++ i) {के लिए (var j = i + 1; j & lt; a.length; ++ j) {if (a [i] === a [j] ]) A.splice (j--, 1); }} वापसी; };  
 
 फिर, इसका उपयोग करने के लिए: 
 
  var array1 = ["विजेंद्र", "सिंह"]; Var सरणी 2 = ["सिंह", "शाक्य"]; // दोनों सरणियों को विलीन करता है और अनूठे आइटम्स प्राप्त होता है var array3 = array1.concat (array2) .unique ();  
 
 यह भी arrays के क्रम को संरक्षित करेगा (यानी, कोई सॉर्टिंग आवश्यक नहीं)। 
 
  संपादित करें:  
 
 चूंकि कई लोग  Array.prototype  और  loops के लिए प्रोटोटाइप संवर्धन के बारे में चिंतित हैं, इसलिए इसका उपयोग करने का एक कम आक्रामक तरीका है:  
 < कोड> फ़ंक्शन सरणीयूवायइक (सरणी) {var a = array.concat (); के लिए (var i = 0; i & lt; a.length; ++ i) {के लिए (var j = i + 1; j & lt; a.length; ++ j) {if (a [i] === a [j] ]) A.splice (j--, 1); }} वापसी; } Var सरणी 1 = ["विजेंद्र", "सिंह"]; Var सरणी 2 = ["सिंह", "शाक्य"]; // दोनों सरणियों को विलीन करता है और अनन्य आइटम्स प्राप्त करता है var array3 = arrayUnique (array1.concat (array2));  
 
 उन भाग्यशाली लोगों के लिए, जहां प्रगतिशील ब्राउज़रों के साथ ईएस 5 उपलब्ध है, आप  Object.defineProperty  इस तरह से उपयोग कर सकते हैं: 
 
  Object.defineProperty (Array.prototype, 'unique', {enumerable: false, configurable: false, writable: false, value: function () {var a = this.concat ()} के लिए (var i = 0; I & lt; a.length; ++ i) {के लिए (var j = i + 1; j & lt; a.length; ++ j) {if (a [i] === ए [जे]) a.splice (j -, 1);}} वापसी;}});

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
