Multiple Nested ng-repeat-start fails to display data
Question
I am trying to flatten out a nested json object & display it in a table.
So I tried using multiple ng-repeat-start & ng-repeat-end elements in a div. But somehow data is not getting displayed.
Plunkr : http://plnkr.co/edit/apuf9YUYnkoSaCDaNYrC?p=preview
HTML :
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');</script>
<link rel="stylesheet" href="style.css" />
<script data-require="angular.js@1.2.x" src="https://code.angularjs.org/1.2.22/angular.js" data-semver="1.2.22"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
Data is :
{{mydata}}
<table cellspacing="1" border="1">
<thead>
<tr>
<td> MainTitle</td>
<td> SubTitle</td>
<td> LastTitle</td>
<td> Final</td>
</tr>
</thead>
<tbody>
<div ng-repeat-start="main in mydata" ng-if="false"></div>
<div ng-repeat-start="sub in main.items" ng-if="false"></div>
<div ng-repeat-start="last in sub.l2items" ng-if="false"></div>
<tr ng-repeat="final in last.l3items">
<td> {{main.title}} </td>
<td> {{sub.title}} </td>
<td> {{last.title}} </td>
<td> {{final}} </td>
</tr>
</tbody>
<div ng-repeat-end ng-if="false"></div>
<div ng-repeat-end ng-if="false"></div>
<div ng-repeat-end ng-if="false"></div>
</table>
</body>
</html>
Code:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.mydata = [
{
title :"hello",
items : [
{
title: "level 1 title",
l2items : [
{
title : "level 2 title",
l3items: [ "a","b" ]
}
]
}
,
{
title: "level 1 title 1 ",
l2items : [
{
title : "level 2 title 1",
l3items: [ "a 1","b 1" ]
}
]
}
]
},{
title :"hello 0",
items : [
{
title: "level 1 title 0",
l2items : [
{
title : "level 2 title 0",
l3items: [ "a 0","b 0" ]
}
]
}
,
{
title: "level 1 title 1 0",
l2items : [
{
title : "level 2 title 1 0",
l3items: [ "a 1 0","b 1 0" ]
}
]
}
],
}]
});
Expected Output : (apologies could not create a proper table)
Main title | Subtitle | LastTitle | Final
hello |level 1 title |level 2 title |a
hello |level 1 title |level 2 title |b
hello |level 1 title 1 |level 2 title 1 |a 1
hello |level 1 title 1 |level 2 title 1 |b 1
hello 0 |level 1 title 0 |level 2 title 0 |a 0
hello 0 |level 1 title 0 |level 2 title 0 |b 0
hello 0 |level 1 title 1 0 |level 2 title 1 0 |a 1 0
hello 0 |level 1 title 1 0 |level 2 title 1 0 b 1 0

I believe the problem is with your HTML. Most likely having divs inside your table. If you convert it to <div> s then it works. Another issue I saw was that you were repeating your closing </body> tag.
I understand why you were doing it with the <div> s and ng-if s. There was, at one time, a comment directive version of the ng-repeat , or at least an effort to create one, but I think they ran into browser limitations .
Here is a similar issue . Perhaps you'll like their solution.
Otherwise, replace your <div> s with <tr> s:
<tr ng-repeat-start="main in mydata" ng-if="false"></tr>
<tr ng-repeat-start="sub in main.items" ng-if="false"></tr>
<tr ng-repeat-start="last in sub.l2items" ng-if="false"></tr>
<tr ng-repeat="final in last.l3items">
<td> {{main.title}} </td>
<td> {{sub.title}} </td>
<td> {{last.title}} </td>
<td> {{final}} </td>
</tr>
<tr ng-repeat-end ng-if="false"></tr>
<tr ng-repeat-end ng-if="false"></tr>
<tr ng-repeat-end ng-if="false"></tr>
