javascript - AngularJS - select with track by doesn't set list object in ng-model -

-

मेरे पास एक चयन है: 

  & lt; नाम चुनें = "data_source" वर्ग = "फॉर्म-कंट्रोल" एनजी-मॉडल = "डेटाडेटा एसोसोर्स" एनजी-ऑप्शंस = "सी.आई.डी. के द्वारा ट्रैक किए गए डेटा_सॉर्स के लिए सी.नाम" & gt; & lt; / select & gt;

मेरे data_sources सरणी में डेटा_सॉर ऑब्जेक्ट 

  {id: "myid", नाम: "mydatasourcename", ...}   
 init data.data_source में एक ऑब्जेक्ट शामिल है जिसे मैं डीबी  
  {id: "myid"} से प्राप्त करता हूं  
 
 सही मान को चुनने में प्रदर्शित किया जाता है लेकिन मेरे एनजी-मॉडल में मेरे पास केवल 'आईडी' विशेषता के साथ मेरे मूल डेटा_सोर्स ऑब्जेक्ट हैं I मैं यहाँ क्या होता है वह ऑब्जेक्ट है जो डेटा के सभी स्रोतों (नाम और अन्य) के साथ array_sources array से आ रहा है। क्या ऐसा करने का एक तरीका है?

हालांकि ड्रॉप-डाउन अपने एनजी मॉडल को स्वचालित रूप से बदलने पर सभी गुणों के साथ अद्यतन किया जा Init पर आप अपने data_source को नीचे तरीके से अद्यतन कर सकते हैं 

  data.data_source = dataFor data_sources = dataListFromServer // अब data_source.id // सेट data_source = matchedObj मिलान करके डेटा_एसॉर्स सरणी के मिलान किए गए obj प्राप्त करें। । इन्हें
पर मॉडल की सही संरचना सुनिश्चित करनी होगी

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
