angularjs - angular interpolation using "async" function -

-

मेरी तालिका में ऐसा कोड है (जेड नोटेशन): 

  table.displaytable t (Ng-repeat = "itemList में आइटम"): टीडी बी {{item.Id}} टीडी {{getTypeName (item.TypeId)}}

और getTypeName वास्तव में कुछ कॉल कर रहा है Async अनुक्रम: 

  $ scope.getTypeName = फ़ंक्शन (टाइप आईडी) {var lang = CurrentLanguageService.getCurrentCulture (); Var label = typesService.getLabelAsync (typeId, lang); वापसी लेबल; }

सेवा में मुझे 

  var getLabelAsync = function (id, langCulture) के रूप में परिभाषित फ़ंक्शन है {return load} (लौंग क्राफ्ट)। तब (फ़ंक्शन ( डेटा) {रिटर्न डेटा;}

मेरे पास निम्न प्रश्न हैं:

  1. क्या मैं अपने वादे के डेटा का सही उपयोग करने के लिए वास्तविक "लेबल"

  2. मुझे वादा को हल करने के लिए कई कॉल्स मिलते हैं (जो कि सर्वर पर तीन कॉल्स ट्रिगर करता है) जबकि मेरे पास इंटरपोलेट करने के लिए केवल एक तालिका होती है?

  3. मैं भी पा रहा हूं

    त्रुटि: [$ interpolate: interr] इंटरपाल्ट नहीं कर सकता: {{getTypeName (item.typeId)}} प्रकार त्रुटि: गुण ' तो 'रिक्त का 

  var getLabelAsync = फ़ंक्शन (id , लैंगकल्चर) {लौटे लोडप्रोमोइज़ (लैंगकल्चर); // बस वादा वापस करें जो बाद में हल करेगा}

अगर आपको अपना स्वयं का वादा करने की आवश्यकता है बाद में हल करें तो आप स्थगित = $ q.defer () का उपयोग कर सकते हैं; और deferrred.promise वापसी; फिर कॉलबैक फ़ंक्शंस में आप स्थगित.रेखे या स्थगित कॉल कर सकते हैं.रोलव अंत में आपके द्वारा बनाए गए नए वादे को हल करें। यदि आपके पास कई वादे हैं और आप जानना चाहते हैं कि उनका सबका समाधान कब हुआ है तो आप $ q.all का भी उपयोग कर सकते हैं।

uislider - In a MATLAB GUI, how does one implement a continuously varying slider from a GUIDE created .m file? -

-
I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
