How to set active class on ng-click? - angularjs

I have this:
<div class="account-item">
<div class="account-heading" ng-class="active">
<h4 class="account-title">
<a href="#/Messages" onclick="SetActiveAccountHeading(this);">
7. #Translate("SYSTEM_MESSAGES")</a>
</h4>
</div>
</div>
<div class="account-item">
<div class="account-heading" ng-class="active">
<h4 class="account-title">
<a href="#/Info" onclick="SetActiveAccountHeading(this);">
7. #Translate("SYSTEM_INFO")</a>
</h4>
</div>
</div>
In angular i have this:
$scope.active = "active";
but how can i change this on click so if user click on menu once it would be active if again click it would be NOT active?

Ok say you have multiple menu items and you want to toggle the class according to click,
you can create a array in the controller which represents the menu items as,
$scope.menuItems = ['Home', 'Contact', 'About', 'Other'];
assign the default selected ,menu item
$scope.activeMenu = $scope.menuItems[0];
create a function to assign the selected Menu value, this function will assign the $scope.activeMenu a last selected menu item.
$scope.setActive = function(menuItem) {
$scope.activeMenu = menuItem
}
in HTML
loop through the menuItems array and create the menu.
in the ng-class check last clicked menu item is equal to item in the repeat.
if click on the menu then call setActive() function in the controller and pass the menu item name as an argument.
<div class="account-item" ng-repeat='item in menuItems'>
<div class="account-heading" ng-class="{active : activeMenu === item}">
<h4 class="account-title">
{{ item }}
</h4>
</div>
</div>
here is the DEMO
here is a DEMO without ng-repeat

This is what you need.
<div class="account-item" ng-init="active = true">
<div class="account-heading" ng-class="{'active': active === true}" ng-click="active = !active">
<h4 class="account-title">
7. #Translate("SYSTEM_MESSAGES")
</h4>
</div>
</div>
No other scripting. +1 if it helps.

Angular4:
<a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
<a [routerLink]="['calendar']" routerLinkActive="active">
Documentation: https://angular.io/api/router/RouterLinkActive

If you are using [ui-router] you not need to write anything just you have add this ui-sref-active="active-menu" property in your tag which you want to active after click/navigate.

For cleaner code try this:
<div class="account-item" ng-init="active = true">
<div class="account-heading" ng-class="{'active': active}">
<h4 class="account-title">
7. #Translate("SYSTEM_MESSAGES")
</h4>
</div>
</div>
You can remove the onclick event SetActiveAccountHeading(this);.
Here's the JsFiddle link.
You can view the result in the developer's console.
Hope it helps.

How to bind a part of a variable already binded

I have a loop ng-repeat that displays sevral icons.
<div class="box">
<div class="box-body">
<div class="row" >
<div class="col-sm-6" style="margin-bottom: 5px;" ng-repeat="record in newlayout.display" align="center">
<a class="btn btn-app" ng-href="#newlayout/{{newlayout.url}}{{newlayout.itemValue}}" >
<span class="badge bg-yellow" style="font-size:22px;">{{record.numberOfSamples}}</span>
<i class="fa fa-{{newlayout.labStyle}}"></i> {{record.lab}}
</a>
</div>
</div>
</div>
</div>
My issue is that the second part of the binded variable itemValue should be dynamic
In my Js, I have this
newLayout.url = 'sublabs/?labName=';
newLayout.itemValue = 'record.lab';
The URL is dynamic.
When I click on the first displayed Icon, the url should look like this :
But it didn't work as I had a compilation error..
Does someone have an idea how to fix this:
http://localhost:8181/#/newlayout/sublabs?labName=PIA/C1 - Shiftlabo
Where the record value "PIA/C1 - Shiftlabo" change.
So basically here if I change
<a class="btn btn-app" ng-href="#newlayout/{{newlayout.url}}{{newlayout.itemValue}}" >
{{newlayout.itemValue}} by {{record.lab}} it would work..but the {{record.**lab**}} should be dynamic as it will have another value when I click on the icon. It will change to {{record.subLab}}
Thanks
Use property acccessor bracket notation inside the binding:
<div>{{record[labOrSublab]}}</div>
JS
var isSublab = false;
$scope.labOrSublab = "lab";
$scope.clickHandler = function() {
isSublab = !isSublab;
$scope.labOrSublab = isSublab ? 'subLab' : 'lab';
};

$scope is only visible in function and thats why is not working

My layout page looks like this:
<li class="dropdown">
<ul class="submenu">
<li>#Translate("MY_ACCOUNT")</li>
</ul>
</li>
In layout page i have : #RenderBody()where i have Index page.In index page im using <div ng-view></div>. What im trying to do is when user click on a href to redirect him on that page and set class to this menu that is render in ng-view:
<div class="account-item">
<div class="account-heading" ng-class="{active : activeMenu === 'Settings'}">
<h4 class=" account-title has-sub">
<a data-toggle="collapse" data-parent="#accordion" href="#settings" ng-click="activeMenu='Settings'">5. #Translate("SETTINGS")</a></h4>
</div>
<div id="settings" class="account-collapse collapse in">
<div class="account-body">
#Translate("PERSONAL_INFORMATION")
#Translate("NOTIFICATIONS")
#Translate("CHANGE_PASSWORD")
#Translate("GAME_SETTINGS")
</div>
</div>
</div>
When i try this nothing happens:
$scope.SetActiveMenuForPersonalInfo = function () {
$scope.activeMenu = 'Settings';
$scope.activeLink = "PersonalInfo";
}
$scope.activeMenu and $scope.activeLink are visible only in function and thats why i cant set class on menu. When i put it out of function it works
Try changing the tripple equality sign in ng-class="{'active-link' : activeLink==='PersonalInfo'}" to double ==
PS: I do not understand the last paragraph

having a list of items ng-repeat on the left, then selecting the main content (on the right) from the options, then displaying the full content as the main selection.
ng-if ? ng-show ?
not sure how well I've described this but it should be pretty obvious from the fiddle.
thanks in advance.
I modified your plnkr http://plnkr.co/edit/9qZsp2o22L5x1a0JofPy?p=preview
I create a currectIssue variable for your right content display.
In left content, Read More.. has been change to <a ng-click="showIssue(x)">Read More..</a>
updated plunk: http://plnkr.co/edit/hGsdkybRMoRct8VykCcB?p=preview
well, you might consider:
- use another scope variable to display the selected item from the object
- I'd use ng-if in this case as that will create/destroy the content as needed
// controller
$scope.selectIssue = function(x) {
$scope.issue = x;
}
$scope.selectIssue($scope.issues['1']);
//view
<article>
<h3 >{{issue.title}}</h3>
<p>{{issue.priority}}</p>
<p class="lead">{{issue.author}} - 6/12/2014</p>
<div ng-if="issue.author == 'Andy'">
<hr>

AngularJS - Show and Hide multiple content

In AngularJS, to simply show a field through an a tag, I would do in this way:
<div ng-show="aField">Content of aField</div>
<a ng-click="aField=true">Show aField</a>
until here, no problem.
I would like now to put more buttons and fields so that, when I click on A it shows the content of A, then when I click on button B, content of A disappears and content of B appears.
How can I do this? Thank you.
UPDATE
Thank you everyone for your solutions, they works! Now, I am doing a template for every content of and because I have much data to show but all in the same structure.
Here the index.html
<div ng-model="methods"
ng-include="'templateMethod.html'"
ng-repeat = "method in methods">
here the script.js:
function Ctrl($scope) {
$scope.methods =
[ { name: 'method1',
description: 'bla bla bla',
benefits: 'benefits of method1',
bestPractices : 'bestPractices',
example: 'example'},
{ name: 'method2',
description: 'bla bla bla',
benefits: 'benefits of method2',
bestPractices : 'bestPractices',
example: 'example'} ];
}
and here the templateMethod.html:
<table>
<tr>
<td>
<div ng-show="toShow=='{{method.name}}Field'">
<h3>{{mmethodethod.name}}</h3>
<p>
<strong>Description</strong>
{{method.description}}
</p>
<p>
<strong>Benefits</strong>
{{method.benefits}}
</p>
<p>
<strong>Best practices</strong>
{{method.bestPractices}}
</p>
<p>
<strong>Examples</strong>
{{method.example}}
</p>
</div>
</td>
<td class = "sidebar">
<ul>
<li><a ng-click="toShow='{{method.name}}Field'" class="{{method.name}} buttons">{{method.name}}</a></li>
</ul>
</td>
</tr>
</table>
It works!
But: if I click the first button and then the second one, the content of the first button do not disappear, it appears under the content of the first button...
Problem with the repetition?
Thanks
It might be better to handle more complex logic in the controller, but in general think about the content of the directive strings as normal js:
<div ng-show="aField">Content of aField</div>
<div ng-show="bField">Content of bField</div>
<a ng-click="aField=true; bField=false">Show aField</a>
<a ng-click="aField=false; bField=true">Show bField</a>
Or use ng-show in concert with ng-hide:
<div ng-show="aField">Content of aField</div>
<div ng-hide="aField">Content of bField</div>
<a ng-click="aField=true">Show aField</a>
<a ng-click="aField=false">Show bField</a>
In the former strategy, nothing shows upon page load. In the latter, the bField content shows by default. If you have more than two items, you might do something like:
<div ng-show="toShow=='aField'">Content of aField</div>
<div ng-show="toShow=='bField'">Content of bField</div>
<div ng-show="toShow=='cField'">Content of cField</div>
<a ng-click="toShow='aField'">Show aField</a>
<a ng-click="toShow='bField'">Show bField</a>
<a ng-click="toShow='cField'">Show cField</a>
I'm guessing that you have a list of items and want to show each item content. Something an accordion component does.
Here is a plunker that shows how you could do it: http://plnkr.co/edit/UTf3dEImiDReC89vULpX?p=preview
Or if you want to display the content on the same place (something like a master detail view) you can do it like this: http://plnkr.co/edit/68DJHL582oY4ecSiiUdE?p=preview
simply use one variable which content is visible. http://jsfiddle.net/gjbw7/
<a ng-click="show='a'">Show aField</a>
.
<div ng-show="show=='a'">Content of aField</div>
I would recommend to create a service in case your fields belong to different controllers.
Service:
App.factory('StateService', function() {
return {
openPanel: ''
};
});
Injecting the service in a Controller:
App.controller('OneCtrl', function($scope, StateService) {
$scope.stateService = StateService;
});
Finally using it a view:
<a ng-click="stateService.openPanel='home'">Home</a>
<div ng-show="stateService.openPanel == 'home'">Content of Home</div>
Demo: http://jsfiddle.net/codef0rmer/BZcdu/
Try this way.
<div>{{content}}</div>
<a ng-click="content='a'">Show aField</a>
<br>
<a ng-click="content='b'">Show bField</a>
<br>
<a ng-click="content='c'">Show cField</a>
<br>
<a ng-click="content='d'">Show dField</a>
<br>
<a ng-click="content='e'">Show eField</a>
<br>
<a ng-click="content='f'">Show fField</a>
Take a look at the ng-switch directive.
<div ng-switch="aField">
<div ng-switch-when="someValue1">
HTML content that will be shown when the aField variable value is equal to someValue1
</div>
<div ng-switch-when="someValue2">
HTML content that will be shown when the aField variable value is equal to someValue2
</div>
<div ng-switch-default>
This is where the default HTML content will go (if aField value is not equal to any of the ng-switch-when values)
</div>
</div>

AngularJS Showing/Hiding content and swapping an image

I have a basic widget block:
<div class="matter ng-controller="ProductsCtrl">
<div class="container-fluid">
<div class="widget">
<div class="widget-head">
<div class="pull-left">Browse live products</div>
<div class="widget-icons pull-right">
<a class="wminimize" href="#" ng-click="showContent = !showContent"><i class="icon-chevron-up"></i></a>
</div>
<div class="clearfix"></div>
</div><!--widget-head-->
<div class="widget-content" ng-class="{ 'hidden': !showContent }">
<div class="padd">
<div>
{{content}}
</div>
</div>
<div class="widget-foot"></div>
</div><!--widget-content-->
</div><!--widget-->
</div>
</div>
And here is the empty controller:
appAdmin.controller("ProductsCtrl", function($scope){
});
I'm using ng-click to hide/show the content, but I am trying to default the content to be visible, and also try to swap the image for the icon chevron down whenever it's hidden. I am very new to Angular and am looking for some direction in adding models and things to make these simple features work.
Any help would be appreciated.
EDIT: Made default visible by switching ng-class="{ 'hidden' : !showContent }" to ng-class="{ 'hidden' : showContent }"
For the content to be visible by default, I would set $scope.showContent to true in the controller. You can use ng-class to change the chevron icon class based on the value of showContent in the following way: <i ng-class="{'icon-chevron-up': showContent, 'icon-chevron-down': !showContent}"></i>. Only the keys of the truthy values will be applied, so it will be either icon-chevron-up or icon-chevron-down. Let me know if I misunderstood your question!
