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>

I have an array of comments. For each of the comment, I have a hidden form where you can reply. That item in each object of the array is called: comment.showSubCommentForm. When I click on Reply, I want to be able to reply with a comment and the function called: commentOnSubPost.
I load my data in chunks of 10 (lazy loading) which I am doing by using the infinite-scroll-distance Angular module. Every time I reach the end of the page, I get the next 10 items and add them to the $scope.comments array, which you can see below is what I am running my ng-repeat on .
The problem is that, although the commentOnSubPost works really well as in it adds the reply to the comment, I have reload the data so I can get the updated $scope.comments with the new reply. BUT - as I have implemented lazy loading, how do I do that if say I am on the 20th page?
I looked at some similar posts but their approach from mine was very different so am very lost.
My HTML:
<div infinite-scroll='loadMore()' infinite-scroll-distance='1'>
<div class="row">
<div ng-repeat="comment in comments track by $index">
<ul class="comments">
<li class="clearfix">
<a ng-href="#">SomeLink</a>
<div>
<p >{{ comment.date }} <a ng-href="/wall#/profile/main/{{ comment.userID }}">{{ comment.fullname }}</a> says <i class="commentReply"><a href ng-click="comment.showSubCommentForm = !comment.showSubCommentForm"><small>Reply</small></a></i></p>
<p class="mainComment">
{{ comment.comment }}
<p class="meta"><i class="showReply"><a href ng-click="comment.showReplies = !comment.showReplies"><small>Show Replies</small></a></i></p>
</p>
</div>
<div ng-show="comment.showSubCommentForm">
<form ng-submit="commentOnSubPost( post._id, comment._id, subComment)">
<div class="form-group">
<div class="form-group">
<textarea ng-model="subComment" class="form-control" placeholder="Reply to the above comment"></textarea>
</div>
<input type="submit" value="Reply">
</div>
</form>
<div ng-show="comment.showReplies" ng-repeat="subComment in comment.subComments track by $index">
<ul class="comments">
<li class="clearfix">
<a ng-href="/wall#/profile/main/{{ comment.userID }}"><img ng-src="{{ subComment.profilePic }}" class="avatar" style="border-radius: 50%"></a>
<div class="post-subComments">
<p class="meta">{{ subComment.date }}<a ng-href="SomeLink"> {{ subComment.fullname }}</a></p>
<p>
{{ subComment.comment }}
</p>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</div>
I won't add too much information here as I don't want to overload this post but if you need any particular information, please do let me know. I just need to know how do I reload the data (or not if there's another approach) so that I can get the latest data.
I hope this makes sense.
Thanks in advance!
Like you have $scope.comments = []; then on each call you just have to append upcoming data to this array.
Like $scope.comments = $scope.comments.concat(response.data);
In this way lazy loading will work.
I fixed this with making a Node route which gives back the exact comment I have just added. Then, I found that commentID in my $scope.comments and made it's subCommenemts to the one I have locally.
It does the job and the data is real. One drawback is that if at that time, there's another comment, it won't show up until the page's refreshed but I'm not too fussed about that.
I'm working on a project where the client has supplied a pile of html where I need to plugin the data from our database and have hit a problem that I'm finding difficult to solve....
So first problem is with routing
<div ng-repeat="class in vm.classes">
<div class="class-overview">
<a href="#">
<span class="class-title">{{class.description}}</span>
... more stuff here
</a>
</div>
<div class="class-information collapse">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
</div>
he has supplied some javascript to handle the click on class-overview
$('.class-overview a').on('click',function(e) {
e.preventDefault();
});
$('.class-overview').on('click',function() {
$('.class-overview.active').removeClass('active').next('.class-information').collapse('hide');
$(this).addClass('active').next('.class-information').collapse('show');//.css('top',offset).collapse('show');
});
and i have a line like this in my state provider
// default route
$urlrouterProvider.otherwise("/")
So the problem is that the ui-router handles the click and sends me back to the home page.
The ideal solution is to leave as much of his markup intact, so can anyone tell me how I stop ui-router handling the click?
or failing that, how I might use ng-click and ng-show to get the same effect, i.e. hiding and showing the class-information div...
If I understand well your question, you want to display the .class-information div when you click on the .class-overview element.
That can be done by using a variable in a ng-show like this:
<div ng-repeat="class in vm.classes">
<div class="class-overview">
<a href="#" ng-click="display = !display">
<span class="class-title">{{class.description}}</span>
... more stuff here
</a>
</div>
<div class="class-information" ng-show="display">
<div class="full-width">
{{class.longDescription}}
</div>
</div>
</div>
The display variable will be falsy when you land on the page, therefore the ng-click will be executed, this variable will be set to true.
I see that you are using a collapse class to hide the content if it is collapsed. Then you could use angular ng-class to put the collapse class when the display variable is false. Your div.class-information would look like this:
<div class="class-information" ng-class="{collapse: !display}">
<div class="full-width">
{{class.longDescription}}
</div>
</div>

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>
<p>{{issue.message}}</p>

first off, i have links from a json and display it using ng-repeat and i want to know if its best practise to load all object property (in a div) corresponding to its link and hide it so when you click a link, the corresponding div shows.
I'm thinking about the worst case scenario, were we have about a 100 links and the load all corresponding divs and hide it o_O
So this is my html:
<a href="">
<div ng-model="showModal" class="contentItem" ng-repeat='meal in recipes | filter:searchText' ng-style="{'background-image':'url({{ meal.url }})'}">
<span id="contentItemHeader">{{ meal.title }}</span>
<span id="contentItemLevel">{{ meal.level }}</span>
</div>
</a>
This is the div (modal) i want to display in full screen:
<div ng-show="showModal" ng-repeat='meal in recipes'>
<span>{{ meal.url }}</span>
<span>{{ meal.method }}</span>
<span>{{ meal.ingredients }}</span>
</div>
Use case is:
-all links loads
-click a link
-corresponding div shows
Thats it ! just like when you see a list of videos on youtube, you click one, then the video page opens but as a modal (same page)
Thanks alot,
regards
You can utilize $modal service from the UI Bootstrap, define template for meal's modal and attach ng-click handler on each individual meal in ng-repeat. In click handle you can open modal and pass meal instance to modal's scope:
View:
<div ng-repeat='meal in recipes' ng-click='selectMeal(meal)'>
{{meal.title}}
</div>
Conrtoller:
$scope.selectMeal = function(meal) {
var dialogScope = $scope.$new(true);
dialogScope.meal = meal;
var modalInstannce = $modal.open({
templateUrl: 'meal-dialog.html',
scope: dialogScope
});
};
Modal template:
<div class="modal-header">
<h3 class="modal-title">{{ meal.title }}</h3>
</div>
<div class="modal-body">
<div>{{ meal.url }}</div>
<div>{{ meal.method }}</div>
<hr />
<h4>Ingridients</h4>
<ul >
<li ng-repeat='ingridient in meal.ingridients' >{{ingridient.name}} : {{ingridient.amount}}</li>
</ul>
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="$close()">Close</button>
</div>
Plunker here
To show div in question, when meal selected, introduce new selectedMeal property in $scope and use it in modal template, remove ng-repeat from modal div and set selectedMeal and showModal in selectMeal function:
$scope.selectMeal = function(meal) {
$scope.selectedMeal = meal;
$scope.showModal = true;
};
<div ng-show="showModal" >
<span>{{ selectedMeal.url }}</span>
<span>{{ selectedMeal.method }}</span>
<span>{{ selectedMeal.ingredients }}</span>
</div>
if your worried about performance of having all the divs exist, but hidden, consider using ng-if instead of ng-show. ng-if does not create the dom element if the expression is false.
<div ng-if="expression">
//element exists if 'expression' is true
</div>
if you are ok to ahead with angular-ui then i think the accordian fits the requirement perfectly... [here's the link for angular-ui's the accordian] directive 1
angular-ui is the pure angularjs implementation of all twitter bootstrap components.
<accordion close-others="oneAtATime">
<accordion-group heading="Static Header, initially expanded" is-open="status.isFirstOpen" is-disabled="status.isFirstDisabled">
This content is straight in the template.
</accordion-group>
<accordion-group heading="{{group.title}}" ng-repeat="group in groups">
{{group.content}}
</accordion-group>
</accordian>
you can have either one or all user selected link detail section open at a time...
I'm new to angular and was wondering how to tackle the following situation. I'm using angular with jquery mobile and am creating a one page app. When the app loads, I have it create pages or divs inside the body tag. I have two types of pages, "typical pages" and "video pages" but I want to use one object to create both page types. I want to use one object because I also use that object to create my menu and I don't want to have to edit multiple objects.
My issue is, I want to create a "typical page" for each element in the object but I only want to create a "video page" for each object that doesn't have "videoPage: false". I tried using ng-if on the "video page" ng-repeater (see html below) but it doesn't seem to be working. Can I use the ng-if on a ng-repeater?
I have the following data/object:
function App($scope){
$scope.pages = [
{
id: "intro",
title: "Intro",
videoPage: false
},{
id: "activeStretches",
title: "Active Stretches by Area"
},{
id: "passiveStretches",
title: "Passive Stretches by Area"
}
];
}
And the html:
<body ng-app ng-controller="App">
<div data-role="page" id="{{page.id}}" ng-repeat="page in pages">
<div data-role="header" data-theme="h">
<a data-rel="back" data-icon="arrow-l">Back</a>
<h1>{{page.title}}</h1>
</div>
<div data-role="content">
<div class="content-side">
<ul data-role="listview" data-inset="true">
<li ng-repeat="menu in pages" data-theme="{{menu.title == page.title && 'h'}}">
{{menu.title}}
</li>
</ul>
<div class="logo"></div>
</div>
<div class="content-main">
Typical Page
</div>
</div>
</div>
<div data-role="page" id="{{page.id}}Video" ng-repeat="page in pages" ng-if="page.videoPage">
<div data-role="header" data-theme="h">
<a data-rel="back" data-icon="arrow-l">Back</a>
<h1 class="vidTitle"></h1>
</div>
<div data-role="content">
<div class="content-side">
<ul data-role="listview" data-inset="true">
<li ng-repeat="menu in pages" data-theme="{{menu.title == page.title && 'h'}}">
{{menu.title}}
</li>
</ul>
<div class="logo"></div>
</div>
<div class="content-main">
Video Page
</div>
</div>
</div>
</body>
ng-if is new as of 1.1.15 so make sure you're using a new (currently unstable) version of Angular.
And, yes, you can mix ng-if with ng-repeat. Here's a fiddle showing it in action (using 1.2): http://jsfiddle.net/rbQry/1/
Note this line (switch the ng-if to "true" and the repeat comes back):
<li ng-repeat="phone in phones | filter:query" ng-if="false">
