create nested objects in javascript like groupby in C# -

-

<पूर्व> IList & lt; ग्राहक & gt; ग्राहक = फ्लैट। समूह (ग्राहक = & gt; नया {cust.ReferenceNumber, cust.Name, cust.Address})। चयन करें (सी = & gt; नया ग्राहक () {संदर्भ संख्या = सी। के.रिफेरनंबर, नाम = सी। केय .नाम, पता = सी.के.ए.एडरेशन, ऑर्डर्स = सी। सेलेक्ट (ओ = न्यू ऑर्डर) (ऑर्डर आयड = ओ। ऑर्डर आयडी, प्रोडक्टनाम = ओ। प्रोडक्ट्नम, विवरण = ओ.डिस्क्रिप्शन, राशि = ओ। ) .ओलिस्ट ()})। ToList ()

क्या एक सपाट सूची ले रही है और इसे जावास्क्रिप्ट में नेस्टेड ऑब्जेक्ट में परिवर्तित कर रहा है? एक सामान्य समाधान है ??

हां

आप जावास्क्रिप्ट के आसपास फ़ंक्शन को पार कर सकते हैं, जो सी # कोड में लैम्ब्डा एक्सप्रेशन के समान प्रयोजन के समान होगा। एक उदाहरण के रूप में JQuery के "प्रत्येक" प्रयोग का प्रयोग करें: 

  $ ('div.several')। प्रत्येक (फ़ंक्शन () {// वर्तमान div से कुछ करो।});

आप भी आसानी से नेस्टेड ऑब्जेक्ट बना सकते हैं: 

  var बाहरी = {inner1: {val1: 'a', val2: 'b'}, आंतरिक 2: {val1: 'c', val2: 'd'}};

बेशक, आप एक बार में सभी की बजाय गतिशील रूप से ऐसा कर सकते हैं: 

  var बाहरी = {}; बाहरी.नर 1 = {}; बाहरी.नर 1.वल 1 = 'ए'; ...

फिर, जो आप ढूंढ रहे हैं उसे करने के लिए, आपको एरे का उपयोग करना होगा: 

  var परिणाम = []; के लिए (var i = 0; i & lt; x; ++ i) {परिणाम [result.length] = GetIndividualResult (i); }

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

c++ - Linux and clipboard -

-
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);
