javascript - Object property cannot be set via setter while using Object.create -

-

On your attempt to know more about the object. I came across.

An example page from the top: 

  var car2 = object. Create (empty); // This is an empty object, such as {} Car2.prototype = {getInfo: function () {return 'a' + this.color + '' + this.desc + '.'; '; }}; Var car2 = Object.create (Car2.prototype, {// value properties color: {writeable: true, configurable: true, value: 'red'}, // concrete rick value rawDesc: {writeable: false, configurable: true, Price: 'Porsche Boxer'}, // Data Properties (Assigned using Gates and Sets) desc: {Configure: True, Receive: Function () {return.rawDesc.toUpperCase ();}, set : Function (value) {This.rawDesc = value.toLowerCase ();}}}); Car2.color = 'Blue'; Warning (car2.getInfo ()); // Display 'A Blue Porsche Boxer.'   
 Question:  
     
  1.  
     How accurate is the above example? It seems that  rawDesc  can be a private member, which can only be modified through  desc  code>. Is it useful in any way?   
  2.  
     In addition,  desc  for  car2.desc = 'Merc'  does not seem to work so why is?   
  3.  
     Parts of the object. Are phyproporty and object.Sent?    
     Research:  
     Some related questions: I tried to delete the  writable: incorrect  and  value : 'Porsche Boxer'  and tried to set the value but there is no benefit.   
     
     
     some comments:  
      var Car2 = Object.create (zero ); // This is an empty object, such as {}   
     The comment is not perfect at all. The internal prototype of  Car2   [[prototype]]  will be  null , so it will be  object.prototype , While an object is created using  {} .  
      Car2.prototype = {...}; Var car2 = Object.create (Car2.prototype, {  
     It seems there is no point in creating  Car2  because this is not a function and it is not used Can not be a manufacturer nor inherited any standard object methods, it is only a placeholder for the object specified for  Car2.prototype . But I think this is just an example.  
     For more questions ?? |  
     
     How is the above example correct? The above example starts refuting the example.   
     How does this example conflict?  
     
     Also, car2.desc = 'Merc' Trying to set a value does not look right.   
     Setter for  desc  actually  rawDesc  , But  rawDesc  is set to  writeable: incorrect . Change it to  writeable: true  and value changes But this one There is public property, by setting some other properties anyway, its value can not be determined slightly.  
     
     Which parts of Object.defineProperty and Object.create are the same?   
     and are imminent in ECMA ???? 262, it is not hard to work, in fact, first adds an asset to only one existing object, the second creates a new object and its  [[prototype]]  (i.e. it is a constructor Is equivalent to) sets.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
