How do you create a pointer to an object property in javascript? -

-

यदि मेरे पास एक वस्तु है: 

  obj = {a: {ए: 1}, बी: 2};

और मैं शॉर्टकट वेरिएबल (obj.a.aa को पॉइंटर) इस तरह से बनाना चाहूंगा: 

  x = obj.a.aa;

और फिर मैं मान 3 को obj.a.aa जैसे एक्स का उपयोग करना चाहता हूँ: 

  x = 3; // मैं obj.a.aa के लिए अब बराबर 3 console.log (obj.a.aa) चाहते हैं; // 1 (मुझे 3 चाहिए)

मैं obj.a.aa में जा रहा मूल्य 3 में परिणाम के लिए कैसे x सेट कर सकता हूँ?

मुझे लगता है कि obj .a.aa एक आदिम है, लेकिन मैं एक वैरिएबल कैसे परिभाषित कर सकता हूँ जो उस बिंदु को इंगित करता है जिसे मैं संपत्ति के लिए एक मान निर्दिष्ट करने के लिए उपयोग कर सकता हूं?

आप x = मान का उपयोग नहीं कर सकते क्योंकि इससे कोई संदर्भ नहीं होगा, केवल एक प्रति ऐसा करने के लिए आपको मूल शाखा का संदर्भ देना होगा: 

  x = obj.a;

फिर मान सेट करें: 

  x.aa = 3;

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...
