[AngularJS] Re: deploying an angular 2 app

[user12345]

HI 

You can create a war file and deploy it with the help of jboss. Actually i 
would suggest to de-couple both front end(Angular) and backend(Any server 
technology) code and deploy them as separate wars. You can use gulp for 
creating a war which will bundle all the js,css and other files which is 
required for rendering of the application

[AngularJS] Angular : How to detect changes made to form automatically

[user12345]

Hi All

Is there any way to detect whether the user has made any change to the form 
using angular form .?

example :

Step 1 : Value for name (type = input) will be : "test".(By default, the 
ng-model will be defaulted as value will be retrieved from API Response).
Step 2 : User has changed value to "test1"
Step 3 : User has changed value to "test".

Is there any attribute inside that form where i can check that the user has 
not changed anything ideally for input directive. I think , dirty, 
pristine, touched elements inside the form will not be used for this 
scenario.

Step 4 : User has changed value to "hello". 
Step 5 : User has changes value to "test"'

So what i am looking is , is there any attribute where i can check whether 
the user has made any change to the input, like for
Step 2-->value should be true
Step 3-->value should be false
Step4-->value should be true.

Thanks !

[AngularJS] Memory Leak while using ng-options (Custom Directive)

[user12345]

Hi

 

In my application(1.3.17 version), we have lot of dropdowns in HTML Pages 
which were created as a part of custom directive(Here the drop down is 
created with the help of custom directive). The data in the dropdowns are 
being filled with the data which we receive as a part of Rest API Call. We 
observed that when we navigate from page which contains drop down to home 
page , we see that memory is still being held by the references and thus 
causing lot of memory leak. 

 

Please find details below :

 

1)File from where custom dropdown will be called :

 

< customDropDown value="request.getID" list="getID">

 

2)customDropDown.directive.js:

 

function customDropDown() {

  return {

restrict: 'E',

scope: {

  id: '@',

  list: '@',

  value: '=',

  form: '=',

  disabled: '@',

  empty: '@'

},

templateUrl: 'customDropDown.html',

controller: function($scope, $rootScope) {

  $scope.disabled = $scope.disabled ? ($scope.disabled === 'true') 
: false;

  $scope.empty = $scope.empty ? ($scope.empty === 'true') : true;

  $scope.model = {value: $scope.value };

  

   //Instead of APi call, I am just Hard Coding 
couple of value ("List" as query parameter in API Call and the data which 
we receive will be huge

   

  $scope.item= 
{"id":1,"name":"one","value":"one"},{"id":2,"name":"two","value":"two"},{"id":3,"name":"three","value":"three"};

 



  });

}

  };

}

 

  })();

 

 

3)customDropDown.html:
