angularjs - How would I share scope between an angular controller and a directive -

-

I am trying to do something like that.

What do I expect to happen that a selected list is displayed and when the option is selected, the word true or false is displayed on it The line of code is:

gt; & Lt; / Span & gt;

$ watch This part acts as an alert that says hey, the card type has changed!

How do I change directive ? 

  .controler ('AddCreditCardChargeCtrl', ['$ scope', function ($ scope) {$ scope.creditCards = [{name: 'MISC' name: 'Mastercard credit' Value: 'VIS', Transaction: 'VIS', Value: 'MSC', 'Visa Debit / DLTA' (name: 'MAESTRO', Value: 'MAE', Transaction: FI: Incorrect}, {Name: 'SWITCH ',': Transaction: Sender: Correct}, {Name: 'MasterCard Debit', Value: 'MCD', Transaction FI: Incorrect} Value: 'SWI', Transaction Eph: Incorrect}, {name: 'Visa Electron' , Value: 'ELC', transaction FI: false}, {name: 'solo', value : 'SOL', transaction FI: false}] $ scope.selectAction = function {warning ($ scope.creditCardModel); Warning (hasTransFee ($ scope.creditCardModel); $ Scope.cardType = hasTransFee ($ scope. CreditCardModel); // console.log (cardType.name) // console.log (cardType.transactionFee) console.log ('clock') $ radius. $ Watch ("cardType.transactionFee", function () {warnings (' Hey, the card type has changed! ');});} Var hasTransFee = function (cardtype) {for (var i = 0; i  ;}}]))    
 
 
  scope: false , so there is no new possibility, in this way you will share the share with the controller  
 Note  
 for  
 edit:  
  link  Try without using Hnkshn to  
 . Directive ('bhtDiscountPrice', ['BasketFactory', function (basketball) {return {restrict: 'EA', radius: correct, template: '& lt; span data-ng-bind = "cardType.transactionFee" & Gt; & Lt; / span & gt; '};});

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
