javascript - NotifySubscribers is not refreshing UI (Writable Computed) -

-

I have a writable writing within a custom binding to format a mapping, however, when users remove the formatted mask , The reading function is not triggered, because all the non-points being viewed are being removed, well, it should work, so I added the notification to everyone to read, even if the honorable price changes and its work, But the UI element is not refreshing the new value (see returns)

Follow the code: 

  ko.bindingHandlers.conta = {init: function (element, value, user) , All BindingsEver, ViewModel, Binding Contx) {Values ​​of Values ​​= value Axtor (), formatted = COPPATED ({read: function} {var val = ko.unwrap (valueAccessor ()); if (! Val) return Val;) if (val.toString (). Length & lt; 6) {val = zeroPad (val, 6); Look (val);} return val.toString () Piece (0, val.toString (). Length - 1) + "-" + val.toString () Piece (val.toString (). Length - 1);}, type: function (value) {if (value) {value = zeroPad (value, 6); } Overview (value location (/ \ D / g, '')); Observable.notifySubscribers (); }}); If ($ (element) .is ('input')) {ko.applyBindingsToNode (element, {numbers: true, maximum length: 10, value: formatted}); } Else {ko.applyBindingsToNode (element, {numbers only: true, text: formatted}); } Return {controlsDescendantBindings: true}; }};   
 
  
 
 = "Text"> 
  formatted  notify  to computed obs : Always : 
 
  ko.bindingHandlers.conta = {init: function (element, value accelerator, all binding equals, view modal, binding contact) {value of honorable value = anassar () , Formatted = COPPEATED ({...}). Expansion ({notify: 'always'}); ...  
 
 This will always force you to notify it even when there is no change.

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
