How to load controller as per specific condition using Angular.js

I am facing some issue. I have some nested controller within one parent controller and I need it to execute as per some condition using Angular.js. I am explaining my code below.
NABH.html:
<div ng-controller=NABHParentController>
<div ng-show="showNabh">
<div ng-include="'nabh1.html'"></div>
</div>
<div ng-show="showNabh1">
<div ng-include="'nabh2.html'"></div>
</div>
</div>
nabh1.html:
<div class="right_panel" style="display:block;" id="auditnabh" ng-controller="NABHController">
<td class="sticky-cell" ng-click="initiateNABH(nabh.NABHAuditID)">
</td>
</div>
nabh2.html:
<div class="right_panel" ng-controller="NABH2Controller">
<h2 class="page-title">NABH (INT012017001)</h2>
<div>
NABHParentController.js:
var app=angular.module('demo');
app.controller('NABHParentController',function($scope,$http,$state,$window,$location,$filter){
$scope.showNabh=true;
$scope.showNabh1=false;
})
NABHController.js:
var app=angular.module('demo');
app.controller('NABHController',function($scope,$http,$state,$window,$location,$filter,getBothIdToAuditDetailPage)
{
$scope.initiateNABH = function(aid) {
$scope.$parent.$parent.showNabh=false;
$scope.$parent.$parent.showNabh1=true;
}
})
Here Initially all controller are loading and nabh1.html is displaying first. When user will click on that td click event the second part html is showing. Here I need when user will click on that ng-click="initiateNABH(nabh.NABHAuditID)" the second view will open and the resepective controller will start execute. Initially only displaying view related controller will execute. Please help.
It sounds like using ng-if instead of ng-show will solve your problem:
<div ng-if="showNabh">
<div ng-include="'nabh1.html'"></div>
</div>
<div ng-if="showNabh1">
<div ng-include="'nabh2.html'"></div>
</div>
The difference is that while ng-show will "only" hide the element using css when the expression is falsy, ng-if will not create the element if it's falsy and as a result will not initiate the controller until ng-if is truthy.
Also, I would probably move the initiateNABH function to the parent controller - it will still be available in the child controller but makes the code less likely to break since you don't have to use $parent:
var app=angular.module('demo');
app.controller('NABHParentController',function($scope,$http,$state,$window,$location,$filter){
$scope.showNabh=true;
$scope.showNabh1=false;
$scope.initiateNABH = function(aid) {
$scope.showNabh=false;
$scope.showNabh1=true;
}
})

Using an angular directive stored in a variable in thymleaf

I am working on an issue in an application that mixes angularjs and thymeleaf. I want to build a template in thymeleaf that will allow me to use a variable to specify an angular attribute directive to use.
It seems like thymeleaf does not allow variables to be used as attributes. I have tried the following:
<div th:attr="${portlet.attrDirective}">
....
</div>
Didn't work
<div th:inline="text">
<div [[${portlet.attrDirective}]]>
...
</div>
</div>
Also didn't work
Am I doing something wrong?
There also is the possiblity of they portlet.attrDirective being null.
I got it working finally using the following code:
<div th:attr="${portlet.attrDirective == null} ? nodirective : ${portlet.attrDirective}=${portlet.attrDirective}">
...
</div>
Does anyone have a more readable solution?

Angularjs ng-repeat index not working

I want to use ng-repeat more or less as follows:
<div ng-repeat="One_Entry in Entries_List track by One_Entry.Entry_ID"
onClick="DoSomething(One_Entry.Entry_ID)">
<!---
present various fields within "One_Entry"
-->
</div>
Entries_List is a JSON array of objects, being Entry_ID one of the elements within the object.
DoSomething is a function within the related controller that is supposed to perform a specific activity on the structure whose ID is the passed Entry_ID.
I tried using $index as well as $parent.$index but I'm getting an error stating that these variable do not exist.
Could anyone tell me how I can achieve the above functionality?
Thanks.
The object One_Entry is scoped. Therefore onclick won't work. Use ng-click instead which is the Angular version for onclick:
<div ng-repeat="One_Entry in Entries_List track by One_Entry.Entry_ID"
ng-click="DoSomething(One_Entry.Entry_ID)">
<!---
present various fields within "One_Entry"
-->
</div>
It's not OnClick it's ng-click
Change
From :
<div ng-repeat="One_Entry in Entries_List track by One_Entry.Entry_ID"
onClick="DoSomething(One_Entry.Entry_ID)">
To:
<div ng-repeat="One_Entry in Entries_List track by One_Entry.Entry_ID"
ng-click="DoSomething(One_Entry.Entry_ID)">

Load angular template on some event

I'm quite new to angular and frontend in general, but what i'd like to see is something similar to what routing with ngView gives, but without routing, i.e just load a template on some event. To be more specific, let's say i have an input field somewhere in the header and when i click/focus on this field a special panel with different input options shows up. The trick is that this input field and other elements are already a part of a template which is loaded into ngView, so as i understand i can't use another ngView for options pane.
use ngIf, ngShow, ngHide, ngSwitch for stuff like that
<button ng-click="showStuff = true">Show Stuff</button>
<button ng-click="showStuff = false">Hide Stuff</button>
<div ng-show="showStuff">Showing Stuff</div>
<div ng-hide="showStuff">Hiding Stuff</div>
Have a look at this plunker for a quick and dirty, working example.
Note that the showStuff variable is just magically created by angular on the root scope, since I'm not using a controller.
You can load templates with ng-if and ng-include like this example:
<body ng-app="app">
<div class='container'>
<button ng-click='tmpl = true' class='btn btn-info'>Load template!</button>
<div ng-if='tmpl'>
<div ng-include="'template.html'"></div>
</div>
</div>
</body>
The ngIf directive will add element to the DOM when the argument expression is true. Then, the angular will compile the inner directive ngInclude, loading the template.

Check checkboxex based on values fron json using Angularjs

I have a simple html that loads JSON data into a table using Angularjs ng-repeat. One of the fields come as 1 or zero. I want to write a simple AngularJs directive that will show check-boxes as either checked(1) or not (0); and show text success against (1) and failure against(0) rows.
I'm starting with angular, you can use ng-model inside your ng-repeat and ng-if to display to decode value inside the loop.
Code:
<div ng-controller="Ctrl">
<div ng-repeat="o in obj">{{o.id}}
<input type="checkbox" ng-model="o.checked">
<div ng-if="o.checked == true">success</div>
<div ng-if="o.checked != true">fail!</div>
</div>
</div>
