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;}});

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

sockets - Delphi: TTcpServer, connection reset when reading -

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
