Working with Bootstrap and AngularJS, is there a way to ng-repeat horizontally with a new row for every set amount of elements?
I have been playing around with ng-class to accomplish this Fiddle, but the problem is that I can't get the float left divs within the initial row div... Any thoughts, am I not thinking of something or would this best be done with a Directive?
Here is my code (live example in the above fiddle link):
<body ng-app="myApp">
<div ng-controller="MyCtrl">
<div ng-repeat="num in numbers"
ng-class="{'row': ($index)%2==0, 'col-md-6': ($index)%2!=0}">
<div ng-class="{'col-md-6': ($index)%2==0}">
{{num}}
</div>
</div>
</div>
</body>
var myApp = angular.module('myApp', [])
.controller('MyCtrl', function ($scope) {
$scope.numbers = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10"];
});
.row {
clear: both;
width: 100%;
border: 1px solid red;
}
.col-md-6 {
width: 50%;
float: left;
border: 1px solid blue;
}
If you are working with Bootstrap 3 and AngularJS you can declare a new filter that will return one array of sub array slices and then do two ng-repeat.
It will look like that:
<div class="row" ng-repeat="row in filtered = (arr | splitArrayFilter:3)">
<div class="col-md-4" ng-repeat="n in row">
<h3>{{n}}</h3>
</div>
</div>
app.filter('splitArrayFilter', function() {
return function(arr, lengthofsublist) {
if (!angular.isUndefined(arr) && arr.length > 0) {
var arrayToReturn = [];
var subArray=[];
var pushed=true;
for (var i=0; i<arr.length; i++){
if ((i+1)%lengthofsublist==0) {
subArray.push(arr[i]);
arrayToReturn.push(subArray);
subArray=[];
pushed=true;
} else {
subArray.push(arr[i]);
pushed=false;
}
}
if (!pushed)
arrayToReturn.push(subArray);
console.log(JSON.stringify(arrayToReturn));
return arrayToReturn;
}
}
});
You can Find it on Plunker here: http://plnkr.co/edit/rdyjRtZhzHjWiWDJ8FKJ?p=preview
for some reason the view in plunker does not support bootstrap 3 columns but if you open it in embedded view or in browsers you can see that it works.
It was clever what you were doing with ng-class. I hadn't ever thought of using %2 within the expression there.
But for future reference, there is a slightly easier way to accomplish that: ng-class-even and ng-class-odd. It does the same thing as what you were doing, but just a bit cleaner:
<div ng-repeat="num in numbers" ng-class-even="'md-col-6'" ng-class-odd="'row'">
{{num}}
</div>
But this doesn't resolve your problem. If I understand you correctly, you want a row, with two columns within that row. The easiest way I could think of is to split up the arrays. Put the repeat on the div, then have 2 span within the div. I think one of the issues that you had originally, is that you were repeating a single div, and trying to treat that block element as an inline
Controller
myApp.controller('MyCtrl', function ($scope) {
$scope.evens = ["2","4","6","8","10","12","14"];
$scope.odds = ["1","3","5","7","9","11","13"];
});
HTML
<div ng-controller="MyCtrl">
<div ng-repeat="odd in odds" class="row">
<span class="span3">{{odd}}</span>
<span class="span2">{{evens[$index]}}</span>
</div>
</div>
Fiddle
Being that you're using version 1.1.5, that also opens you up to a new directive: ng-if! You could also use ng-switch to do some conditional logic displays.
You didn't include bootstrap in your fiddle, and for some reason I can't get jsFiddle to display bootstrap. So I created some temp CSS classes that would somewhat resemble bootstraps class="span"
No need to add .row class .. I did this:
HTML:
<div ng-repeat="product in allProducts">
<div class="my-col-50">
<h1>{{product.title}}</h1>
</div>
</div>
CSS:
.my-col-50{float:left;width:50%;}
and it's work like a charm.
Although this isn't the "proper" way of doing this, there is a way to achieve this using CSS.
For example, this is for a 3 column layout:
HTML:
<div class="row">
<div ng-repeat="(key, pod) in stats.pods" class="pod-wrap">
<div ng-if="objectCheck(pod) == false" class="col-md-4 col-sm-4 pod">
<div>
<h2 ng-bind="key"></h2>
<p class="total" ng-bind="pod | number"></p>
</div>
</div>
<div ng-if="objectCheck(pod) == true" class="col-md-4 col-sm-4 pod">
<div>
<h2 ng-bind="key"></h2>
<div ng-repeat="(type, value) in pod track by $index">
<p class="status"><% type %> <small><% value %></small></p>
</div>
</div>
</div>
</div>
</div>
CSS:
.pod-wrap:nth-of-type(3n):after {
display: table;
content: '';
clear: both;
}
I tried two of the suggestions given here...
the one by yshaool works fine but like i commented on it give me that infinite loop error.
Then I tried something like below:
<div class="row" ng-repeat="row in split($index, 3, row.Attempts)">
<div class="col-md-4" ng-repeat="attempt in row">
<div>Attempt {{row.AttemptNumber}}</div>
<div>{{row.Result}}</div>
</div>
</div>
and the function:
$scope.split = function (index, length, attempts) {
var ret = attempts.slice(index * length, (index * length) + length);
console.log(JSON.stringify(ret));
return ret;
}
was going somewhere with that when i realized that it could be as simple as
<div ng-repeat="attempt in row.Attempts">
<div class="col-md-4">
<div>Attempt {{attempt.AttemptNumber}}</div>
<div>{{attempt.Result}}</div>
</div>
</div>
using "col-md-4" does the trick as I only need to split using three columns per row..
(let bootstrap do the work!)
anyway the other answers here were really useful...
Depending upon the number of columns that you need in your template, create chunks of the original data source in your controller.
$scope.categories = data //contains your original data source;
$scope.chunkedCategories = [] //will push chunked data into this;
//dividing into chunks of 3 for col-4. You can change this
while ($scope.categories.length > 0)
$scope.chunkedCategories.push($scope.categories.splice(0, 3));
In your template you can now do the following
<div class="row" ng-repeat="categories in chunkedCategories">
<div class="col-xs-4" ng-repeat="category in categories">
<h2>{{category.title}}</h2>
</div>
</div>
My approach was to use the $index variable, which is created and updated by AngularJS within an ng-repeat directive, to trigger a call to the CSS clearfix hack which, in turn, resets to a new row.
I am using the following versions: AngularJS 1.5.5 and Bootstrap 3.3.4
<!-- use bootstrap's grid structure to create a row -->
<div class="row">
<!-- Cycle through a list: -->
<!-- use angular's ng-repeat directive -->
<div ng-repeat="item in itemList">
<!-- Start a new row: -->
<!-- use the css clearfix hack to reset the row -->
<!-- for every item $index divisible by 3. -->
<!-- note that $index starts at 0. -->
<div ng-if="$index % 3 == 0" class="clearfix"></div>
<!-- Create a column: -->
<!-- since we want 3 "item columns"/row, -->
<!-- each "item column" corresponds to 4 "Bootstrap columns" -->
<!-- in Bootstrap's 12-column/row system -->
<div class="col-sm-4">
{{item.name}}
</div>
</div>
</div>
To keep solution bootstrap formated i solved this using ng-class
<div ng-repeat="item in items">
<div ng-class="{ 'row': ($index + 1) % 4 == 0 }">
<div class="col-md-3">
{{item.name}}
</div>
</div>
</div>

I am a beginner at angular. I am pretty certain I am doing this the completely incorrect way but because I finally have it "somewhat working" as it works on the second click I am stuck going in this direction and can't seem to figure out another way to do it.
The filter sorts on the second click because it is initialing as "undefined" before the first click and sets it based on that I believe.
In my html:
<div class="col-xs-12 col-sm-4 location-list" ng-repeat="key in careerlist.location">
<div class="locations" ng-click="careerlist.criteriaMatch()">{{key}}
</div>
</div>
<div class="col-xs-12">
<div class="row">
<div class="col-xs-12 col-sm-6 col-md-4 job-container" ng-repeat="job in careerlist.career | filter : searchText | filter: selectExperience | filter: careerlist.criteria.name">
<h2>
{{job.title}}
</h2>
<h3>
{{job.location}}
</h3>
<div class="job-description" ng-bind-html="job.description | limitHtml : 200">
</div>
<br><br>
<button>Read More</button>
</div>
<br><br>
</div>
</div>
In my controller:
cl.criteriaMatch = function( criteria ) {
jQuery(document).on('click', '.locations', function(){
cl.criteria = {};
console.log("just the element text " + jQuery(this).text());
cl.criteria.name = jQuery(this).text();
return function( criteria ) {
return criteria.name === criteria.name;
};
});
};
Use ng-click instead of jQuery#on('click'). Angular does not know that the filter should be updated.
Update
#Makoto points out that the click is bound twice. It very much looks like you should just remove the jQuery binding altogether. I would even go so far as suggesting removing jQuery from you project.
I'm trying to display a Banner <div> after 2 rows of 4 x "col-md-3", followed by another 2 Rows - so the resulting markup would look like:
<div class="col-md-3">1</div>
<div class="col-md-3">2</div>
<div class="col-md-3">3</div>
<div class="col-md-3">4</div>
<div class="col-md-3">5</div>
<div class="col-md-3">6</div>
<div class="col-md-3">7</div>
<div class="col-md-3">8</div>
<div class="col-md-12" id="Banner">Banner</div>
<div class="col-md-3">9</div>
<div class="col-md-3">10</div>
<div class="col-md-3">11</div>
<div class="col-md-3">12</div>
<div class="col-md-3">13</div>
<div class="col-md-3">14</div>
<div class="col-md-3">15</div>
<div class="col-md-3">16</div>
Trying to simulate this using AngularJS so would have to use ng-repeat - but cannot seem to get this working. Any help appreciated: My Plunker
<div ng-repeat="n in Numbers">
<div class="col-md-3">{{n}}</div>
</div>
There are just a couple of problems with your plunker. First maincontroller.js is missing the .js extension, so it is never loaded.
Next all of the references to load angular should start with https instead of just http.
To display the banner after a certain number of rows place it within the first div and use something like:
<div class="col-md-12" id="Banner" ng-if="$index==5">Banner</div>
Not sure if 5 is the number you want there or if you want to use some kind of expression to see if ng-if is divisible by a certain value, but using $index and ng-if should get you there.
You could use ng-repeat-start and ng-include with a ng-if to conditionally include the banner if it's at the correct index with n===8.
Please have a look at the code below or in this plunkr.
angular.module("app", [])
.controller("MainController", mainController);
function mainController($scope) {
$scope.Numbers = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16];
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="container" ng-controller="MainController" ng-app="app">
<h1>Demo</h1>
<div class="col-md-3" ng-repeat-start="n in Numbers">{{n}}</div>
<div ng-include="'banner.html'" ng-if="(n === 8)" ng-repeat-end></div>
<script type="text/ng-template" id="banner.html">
<div class="col-md-12" id="Banner">Banner</div>
</script>
</div>
I have below div (class name 'sp') which I would like to dynamically create based on the sk from a dataset object.
div code
<div style="" class="swindow">
<div class="sp" style="">
<div class="svis" style="">
<div style="height:95%;width:95%;margin-top:0px;margin-left:5px;">
<chart dsn="dyndata" editable="false" labelled="true"></chart>
</div>
</div>
<div class="sdata" style="">
<div class="stext" style="">Average:78% </div>
</div>
</div>
While searching for similar examples, I came across ng-repeat in Angular js and I thought it might suit for this kind of objective.
But am very new to Angular js and not sure how to assign the data to my dyndata variable dynamically and create new div (class=sp) for each of the given id.
Here is the lookup object
[
{"id":20,"st":[{"label":"Audi","value":10},{"label":"BMW","value":70}]},
{"id":26,"st":[{"label":"Benz","value":40},{"label":"BMW","value":20}]},
{"id":12,"st":[{"label":"AUDI","value":60},{"label":"Tesla","value":70}]},
{"id":57,"st":[{"label":"MZ","value":30},{"label":"Honda","value":40}]}
]
When I input the id's as a set [12,26,57] - Three divs (each for #sp) should get created one for each of ids. In those, each div should have the dyndata assigned with the respective 'st' from above javascript object.
I could create div's in jquery using .append function to the container (#swindow) each time when I need. But am not sure how to assign sk as input to dyndata dataset for each div that gets created.
Could you please share how this can be achieved using Angular js ?
Here is the angular js code I used -
<script>
var app = angular.module('ExampleApp', ['ui.plot']);
app.controller('PlotCtrl', function ($scope) {
$scope.dyndata={};
});
</script>
I'm not exactly sure what you're trying to do but I think it should look something like this. Here is a plnkr..
Controller:
app.controller('PlotCtrl', function($scope) {
$scope.items = [
{"id":20,"st":[{"label":"Audi","value":10},{"label":"BMW","value":70}]},
{"id":26,"st":[{"label":"Benz","value":40},{"label":"BMW","value":20}]},
{"id":12,"st":[{"label":"AUDI","value":60},{"label":"Tesla","value":70}]},
{"id":57,"st":[{"label":"MZ","value":30},{"label":"Honda","value":40}]}
]
});
HTML:
<body ng-controller="PlotCtrl">
<div style="" class="swindow">
<div class="sp" style="" ng-repeat="item in items">
<div class="svis" style="">
<strong>{{item.id}}:</strong>
<div>-{{item.st[0].label}}</div>
<div>-{{item.st[1].label}}</div>
<div style="height:95%;width:95%;margin-top:0px;margin-left:5px;">
<chart dsn="dyndata" editable="false" labelled="true"></chart>
</div>
</div>
<div class="sdata" style="">
<div class="stext" style="">Average:78% </div>
<br>
</div>
</div>
</div>
</body>
I'm trying to acheive the same behavior as the spring code below:
<c:forEach items="${data}" var="data" varStatus="contador">
<c:if test="${(contador.count-1)%3==0}">
<div class="conjunto-${conjunto} row"> <!-- Show opening div -->
</c:if>
<!-- Some HTML goes here -->
<c:if test="${((contador.count-1)%3==2)}">
</div>
</c:if>
</c:forEach>
Explaining: I want a new div from class row only after 3 other HTML elements have been added.
I have tried this with ng-if, like this:
<div ng-repeat="data in DATA">
<div class="conjunto-{{$index/3}} row" ng-show="$index % 3 == 0" ng-include="'html.html'">
</div>
<div ng-show="$index % 3 != 0" ng-include="'html.html'">
</div>
</div>
But it obviously doesnt work because only one element with be inside de div.row.
Is there an if-clause with which I could add only the opening div and then close it later?
Thanks in advance.
Ok the best way to do this IMO is 2 fold, in your controller have a method similar to this
$scope.createDataChunks = function() {
var a = $scope.DATA,
retArr = [];
while(a.length) {
retArr.push(a.splice(0,3));
}
return retArr;
}
This would give you an array of arrays, each containing 3 (or less) items in it, you then have this as your markup
<div ng-repeat="data in createDataChunks()">
<div class="conjunto-{{$index/3}} row" ng-show="$index % 3 == 0" ng-include="'html.html'">
<!-- put custom HTML here -->
</div>
</div>
I think that's roughly what you are after?
I have an angularjs app that streams data via ajax, and I would like to ng-repeat over the data. I have the data streaming and displaying but now I want to templatize the objects. The issue I am running into is that I am using ng-repeat simply to index into an array in the controller. I now need to have a
<div class="row" data-ng-repeat="row in rows">
<div class="span3" data-ng-repeat="col in cols">
//displays the raw json fine
{{ data[$parent.$index * numColumns + $index] }}
// also displays the raw json
{{ item = data[$parent.$index * numColumns + $index] }}
<div>Id: {{item.Id}} </div>
<div>Title: {{ item.ClientJobTitle }}</div>
...
</div>
</div>
I could always repeat the array index expression for each property, but there will be a couple dozen properties, so the code will be ugly and all the repeated calculations will slow things down.
What is the right (angular) way to do this?
Update
I need it to be responsive too, I will be adjusting the number of columns on the fly based on window width.
Update
I guess what I really want is something like the following non-working example
<div class="row" data-ng-repeat="row in rows">
<div class="span3" data-ng-repeat="col in cols">
<div ng-model="data[$parent.$index * numColumns + $index]">
<!-- Here $model would refer to the ng-model above -->
<div>Id: {{$model.Id}} </div>
<div>Title: {{ $model.Title }}</div>
...
</div>
</div>
</div>
You've probably handled the issue some way, but it's worth a mention that your non-working example is absolutely possible, even without directives:
var app = angular.module('app',[])
app.controller('myCtrl', function($scope) {
$scope.numColumns = 2
$scope.rows = [1,2,3]
$scope.cols = [1,2]
$scope.data = [
{Id:'abc',Title:'cde'},
{Id:'qwe',Title:'rty'},
{Id:'asd',Title:'fgh'},
{Id:'foo',Title:'bar'},
{Id:'uni',Title:'corn'},
{Id:'mag',Title:'ic'},
];
$scope.change1 = function(){
$scope.numColumns = 2
$scope.rows = [1,2,3]
$scope.cols = [1,2]
}
$scope.change2 = function(){
$scope.numColumns = 3
$scope.rows = [1,2]
$scope.cols = [1,2,3]
}
});
.span3 {
display:inline-block;
padding:5px;
margin:5px;
background: pink;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.5/angular.min.js"></script>
<body ng-app="app">
<div ng-controller="myCtrl">
<button ng-click="change1()">2x3</button>
<button ng-click="change2()">3x2</button>
<div class="row" data-ng-repeat="row in rows">
<div class="span3" data-ng-repeat="col in cols">
<div>
{{($model = data[$parent.$index * numColumns + $index])?'':''}}
<!-- Here $model would refer to the ng-model above -->
<div>Id: {{$model.Id}} </div>
<div>Title: {{ $model.Title }}</div>
...
</div>
</div>
</div>
</div>
</body>
basically, it's possible to create such variable as "$model" on the fly, inside expression:
{{($model = data[$parent.$index * numColumns + $index])?'':''}}
It won't be printed itself, it'll be responsive, working inside ng-repeat and all. Still, it's kind of workaround, and directive might be a better choice.
I think the way to do this would be to simply loop through the items themselves, and ditch all the numRows and numColumns.

That is outputting exactly what yours is doing, with much simpler angularjs code.
It seems that you are using the row/column counts to limit how many items you display on a row horizontally. I think you can handle this with pure css, you can see in my plunk I'm limiting the width on a parent container. I'm doing it manually, but you could easily attach a dynamic css class to the parent container and have more flexible control over how many items appear on a row.
