Angular.js ng-repeat across multiple elements
JavascriptJqueryAngularjsAngularjs Ng-RepeatJavascript Problem Overview
This question has been partly addressed here: https://stackoverflow.com/questions/12979205/angular-js-ng-repeat-across-multiple-trs?answertab=active
However that is just a work-around really, it doesn't actually address the core issue, which is: how can one use ng-repeat across multiple elements without a wrapper?
For example, jquery.accordion requires you to repeat an h3 and div element, how could one do this with ng-repeat?
Javascript Solutions
Solution 1 - Javascript
We now have a proper support for this, please see:
AngularJs Commmit
with this change you can now do:
<table>
<tr ng-repeat-start="item in list">
<td>I get repeated</td>
</tr>
<tr ng-repeat-end>
<td>I also get repeated</td>
</tr>
</table>
Solution 2 - Javascript
To answer Andre's question above on more than 2 levels of ng-repeat in a table, you can use multiple ng-repeat-start to accomplish this.
<tr ng-repeat-start="items in list">
<td>{{items.title}}</td>
</tr>
<tr ng-repeat-start="item in items">
<td>{{item.subtitle}}</td>
</tr>
<tr ng-repeat-end ng-repeat="value in item.values">
<td>{{value.col1}}</td>
<td>{{value.col2}}</td>
</tr>
<tr ng-repeat-end></tr>
Here is a plunker example
Solution 3 - Javascript
UPDATE: This answer is outdated. Please see @IgorMinar answer and use standard ng-repeat-start and ng-repeat-end directives.
There are two options:
First option is to create directive that will render several tags and replace source tag ([jsfiddle][1])
<div multi ></div>
angular.module('components').directive('multi', function ($compile) {
return {
restrict: 'A',
scope : {
first : '=',
last : '=',
},
terminal:true,
link: function (scope, element, attrs) {
var tmpl = '', arr = [0,1,2,3]
// this is instead of your repeater
for (var i in arr) {
tmpl +='<div>another div</div>'
}
var newElement = angular.element(tmpl);
$compile(newElement)(scope);
element.replaceWith(newElement);
}
})
Second option is to use updated source code of angular that enables comment style ngRepeat directive ([plnkr][2])
<body ng-controller="MainCtrl">
<div ng-init="arr=[0,1,2]" ></div>
<!-- directive: ng-repeat i in arr -->
<div>{{i}}</div>
<div>{{ 'foo' }}</div>
<!-- /ng-repeat -->
{{ arr }}
<div ng-click="arr.push(arr.length)">add</div>
</body>
