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...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket?

What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....

c++ - Why does Visual Studio Release build break on non-executing code line -

When I created my C ++ program with the default release configuration in Visual Studio 10, I put a breakpoint on one line Who should never be reached. What confunded me was that when the program is running then it stopped at the breaking point. Adding a volatile statement and transferring this line to the break point does not break the execution of the code where the brake appears (though does not produce the same behavior as creating a minimum project with this function). Why is the "Release Debugger" (?) Step on this line and when executing breakpoints are executed? If I keep going after the break then false statement continues to return code execution. bool bounding box :: Cutting (int32_t xpos, int32_t ypos, int32_t dx, int32_t dy) const {int32_t intersectionX; Int32_t intersections; If ((dx> 0 & amp; amp; and & amp; xpos> rights) || (dx gt; Top) || (D & LT; 0 & amp; AOPO & Lt; BOT)) Return; If (DX! = 0) {intersection Y = ypos + (left...
