javascript - Angular View {{ var }} updating, but $scope.var doesn't change? -

-

I am using UI-Bootstrap, and I had to face some strange.

The following is used for the markup: Directorate Directory, Rate Value and Rate Max 

  & lt; Div class = "RatingContainer text centered" & gt; Two variables are passed in & Lt; Rating value = "rate value" max = "rate max" & gt; & Lt; / Ratings & gt; & Lt; / Div & gt; & Lt; h4 & gt; {{RateValue}} / {{Rate Max}} & lt; / H4 & gt;   
 The odd thing is that I can see the rate value variable which is updating in the scene, when I select different stars. But the value of the variable is not updated in the $ diameter view model.  
  app.controller ('addModalCtrl', function ($ scope, $ modalInstance, selected movie, myMovieService) {$ scope.rateValue = 0; $ scope.rateMax = 10; $ scope.selectedMovie = Selected movie; $ scope.addToLib = function (items) {var jsonData = {tmdb_id: $ scope.selectedMovie.id, my_rating: $ scope.rateValue // It always remains 0};    
 
 
 Not sure which is actually going wrong, but I think its scope is primitives due to variables and Not due to objects; which behaves unexpectedly  
 Normally the variable Instead of using directly it is better to use an object to store the scope values, so you should put your scope variable in an object like this:  
  $ scope .vals = { }; $ scope.vals.rateValue = 0; $ scope.vals.rateMax = 10; // etc. Functions do not need to be in an object: $ scope.addToLib = function (items) {// ... < / Code>  
 and  
  & lt; h4 & gt; {{Vals.rateValue}} / {{vals.rateMax}} & lt; / H4 & gt;

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
