javascript - TypeError trying to set model object in Backbone.js -


मैं backbone.js + cordova + need.js चौखटे के साथ खेल रहा हूं, मुख्यतः क्रिस्टोफे कोएनराइट्स । मेरे मॉडल को एक दृश्य में प्रदर्शित करना सरल लगता है, लेकिन मैं अभी भी सेट या सहेजने के लिए कॉल के माध्यम से मॉडल को अपडेट करने में असमर्थ हूं।

मेरा मॉडल ऐसा कुछ दिखता है: 

 < Code> SourcePhrase = Backbone.Model.extend ({// डिफ़ॉल्ट मान डिफ़ॉल्ट: {id: null, मार्कर: "", orig: null, स्रोत: "", लक्ष्य: ""}, सिंक: फ़ंक्शन (विधि, मॉडल, विकल्प) {if (method === "read") {findById (this.id) .done (function (डेटा) {options.success (data);})}}}}), // etc

मैं प्राप्त करने के लिए कॉल करके अपने संग्रह से ऑब्जेक्ट खींच सकता हूं: 

  // मॉडल ऑब्जेक्ट ढूंढें और अपडेट करें var strID = $ (event.currentTarget.parentElement ) .attr ( 'आईडी'); Var मॉडल = this.collection.get (strID);

अब तक, बहुत अच्छा: 

  मॉडल.सेट ('लक्ष्य', ट्रिम किए गए वेल्यू);

प्रकार त्रुटि: 'अपरिभाषित' एक फ़ंक्शन नहीं है (मूल्यांकन '(i = t [r])। Callback.call (i.ctx, n, a)') < / मजबूत>

हम्म ... ये सही नहीं है 

  मॉडल: ऑब्जेक्ट _changing: गलत _ईवेंट्स  
 संपादित करें: सेट करने के लिए कॉल करने से पहले मॉडल के लिए कंसोल आउटपुट:  ऑब्जेक्ट सीड: "सी 15" संग्रह: ऑब्जेक्ट बदलना: ऑब्जेक्ट डीपींडिंग: ऑब्जेक्ट एट्रीब्यूट्स: ऑब्जेक्ट आईडी: "आरयूटीआईटी 00110" मार्कर: "एचडब्ल्यूआर" मूल: नल स्रोत: "रूथ" लक्ष्य: "रूथ" __प्रोटो__: ऑब्जेक्ट आईडी: "RUT001-10" __प्रोटो__: ऑब्जेक्ट आरआरआईडी: "आरयूटीआईटी 00110"

<पी > हाँ, इसका उपयोग करने का सही तरीका है, और आप इस तरह अपना कोड भी बदल सकते हैं: 

  this.model.bind ('change', this.render, this);

और यह काम करेगा।

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

ios - How to determine if NSLayoutConstraint is horizontal or vertical? -

The only way to try to make this difference is by [constraint description]; Calling and then the resulting string "V:" or "H:" I want to find this information, because of I have around 2 similar restrictions which are prototype storyboard UITableViewCell , the only difference is that supervision is horizontal Describes the distance, and the second vertical. Any suggestion would be very helpful! Edit: I accepted the reply of Grimozoar because its interpretation is a great answer and the way I am working to parse the details, @ kongtomorrow I also want to give credit, answered me here! Thanks for the help! Here is the real code that I used to find the hindrance: NSArray * constraints = [bubble constraints]; (If ([[obstacle first item]], then e-mail: message labels] and [[barrier is second int.] Is aqual: bubble] and amp; a...

c# - Updated Castle to 3.2.1 from 3.0.0 now I cant use FirstNonGenericCoreInterface -

Image
After I upgraded to 3.2.1 Castle I think I can not find the right replacement for the FirstNonGenericCoreInterface My code container.Register (AllTypes .FromAssemblyNamed ("MySolution.Tasks") .Innamespace ("MySolution.Tasks") .WithService.FirstNonGenericCoreInterface ("MySolution.Domain" )); This method is not obsolete and which method I can not use it Does anybody know what I should use instead? If I'm not mistaken, FirstNonGenericCoreInterface is an intense architecture extension method. WithService.DefaultInterfaces () does that, then what should you do with your implementation class name interface? More information is available at Castle Windsor Wiki
