I have a nested json object array and I am able to display Inner Items grouped By Info in HTML using ng-repeat. I have a checkbox in front of each Inner Item where I am handling ng-click event and passing the selected Inner Items to the controller. But now I also wanted to pass Info id in the ng-click event. Can I concatenate the Info array to Inner items array in the ng-click
Here is the json :
[
{
"Info": {
"id": "a1",
"name": "a1-Info",
"InnerInfo": [
{
"name": "xyz"
}
]
},
"InnerItems": [
{ "id": "i1" },
{ "id": "i2" }
]
}
]
<tr ng-repeat=“I in MyData">
<td> {{I.Info.name}}
<table>
<tr><td>
<div ng-repeat=“item in I.InnerItems ">
<input type="checkbox" name="values" ng-click=“getInfo(I);getInnerItems(item)” ng-true-value="1" ng-false-value="0"/>{{item.name}}
</div>
</td>
</tr>
</table>
</td>
</tr>
I need to pass both arrays to one function instead of the above way. Any suggestions?
Use an expression with ng-click to set a property on the controller.
Say you have a property on the controller activeData, then use ng-click like this:
ng-click="activeData = [I , item]"
I have passed multiple parameters to one of my functions itself like getInfo (I, items) and tried to access in controller without having to use any property. It works fine

I am defining a custom filter like so:
<div class="idea item" ng-repeat="item in items" isoatom>
<div class="section comment clearfix" ng-repeat="comment in item.comments | range:1:2">
....
</div>
</div>
As you can see the ng-repeat where the filter is being used is nested within another ng-repeat
The filter is defined like this:
myapp.filter('range', function() {
return function(input, min, max) {
min = parseInt(min); //Make string input int
max = parseInt(max);
for (var i=min; i<max; i++)
input.push(i);
return input;
};
});
I'm getting:
Error: Duplicates in a repeater are not allowed. Repeater: comment in item.comments | range:1:2 ngRepeatAction#https://ajax.googleapis.com/ajax/libs/angularjs/1.1.4/an
The solution is actually described here: http://www.anujgakhar.com/2013/06/15/duplicates-in-a-repeater-are-not-allowed-in-angularjs/
AngularJS does not allow duplicates in a ng-repeat directive. This means if you are trying to do the following, you will get an error.
// This code throws the error "Duplicates in a repeater are not allowed.
// Repeater: row in [1,1,1] key: number:1"
<div ng-repeat="row in [1,1,1]">
However, changing the above code slightly to define an index to determine uniqueness as below will get it working again.
// This will work
<div ng-repeat="row in [1,1,1] track by $index">
Official docs are here: https://docs.angularjs.org/error/ngRepeat/dupes
For those who expect JSON and still getting the same error, make sure that you parse your data:
$scope.customers = JSON.parse(data)
I was having an issue in my project where I was using ng-repeat track by $index but the products were not getting reflecting when data comes from database. My code is as below:
<div ng-repeat="product in productList.productList track by $index">
<product info="product"></product>
</div>
In the above code, product is a separate directive to display the product.But i came to know that $index causes issue when we pass data out from the scope. So the data losses and DOM can not be updated.
I found the solution by using product.id as a key in ng-repeat like below:
<div ng-repeat="product in productList.productList track by product.id">
<product info="product"></product>
</div>
But the above code again fails and throws the below error when more than one product comes with same id:
angular.js:11706 Error: [ngRepeat:dupes] Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater
So finally i solved the problem by making dynamic unique key of ng-repeat like below:
<div ng-repeat="product in productList.productList track by (product.id + $index)">
<product info="product"></product>
</div>
This solved my problem and hope this will help you in future.
What do you intend your "range" filter to do?
Here's a working sample of what I think you're trying to do: http://jsfiddle.net/evictor/hz4Ep/
HTML:
<div ng-app="manyminds" ng-controller="MainCtrl">
<div class="idea item" ng-repeat="item in items" isoatom>
Item {{$index}}
<div class="section comment clearfix" ng-repeat="comment in item.comments | range:1:2">
Comment {{$index}}
{{comment}}
</div>
</div>
</div>
JS:
angular.module('manyminds', [], function() {}).filter('range', function() {
return function(input, min, max) {
var range = [];
min = parseInt(min); //Make string input int
max = parseInt(max);
for (var i=min; i<=max; i++)
input[i] && range.push(input[i]);
return range;
};
});
function MainCtrl($scope)
{
$scope.items = [
{
comments: [
'comment 0 in item 0',
'comment 1 in item 0'
]
},
{
comments: [
'comment 0 in item 1',
'comment 1 in item 1',
'comment 2 in item 1',
'comment 3 in item 1'
]
}
];
}
If by chance this error happens when working with SharePoint 2010: Rename your .json file extensions and be sure to update your restService path. No additional "track by $index" was required.
Luckily I was forwarded this link to this rationale:
.json becomes an important file type in SP2010. SP2010 includes certains webservice endpoints. The location of these files is 14hive\isapi folder. The extension of these files are .json. That is the reason it gives such a error.
"cares only that the contents of a json file is json - not its file extension"
Once the file extensions are changed, should be all set.
Just in case this happens to someone else, I'm documenting this here, I was getting this error because I mistakenly set the ng-model the same as the ng-repeat array:
<select ng-model="list_views">
<option ng-selected="{{view == config.list_view}}"
ng-repeat="view in list_views"
value="{{view}}">
{{view}}
</option>
</select>
Instead of:
<select ng-model="config.list_view">
<option ng-selected="{{view == config.list_view}}"
ng-repeat="view in list_views"
value="{{view}}">
{{view}}
</option>
</select>
I checked the array and didn't have any duplicates, just double check your variables.
Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys.
Repeater: {0}, Duplicate key: {1}, Duplicate value: {2}

If you call a ng-repeat within a < ul> tag, you may be able to allow duplicates. See this link for reference.
See Todo2.html

I faced this error because i had written wrong database name in my php api part......
So this error may also occurs when you are fetching the data from database base, whose name is written incorrect by you.
My JSON response was like this:
{
"items": [
{
"index": 1, "name": "Samantha", "rarity": "Scarborough","email": "maureen#sykes.mk"
},{
"index": 2, "name": "Amanda", "rarity": "Vick", "email": "jessica#livingston.mv"
}
]
}
So, I used ng-repeat = "item in variables.items" to display it.
In following table there can be more than one list on particular date. So For list column there can be more than one list for given date.
I am able to insert more than one value in single cell but it shift the row in which I inserted more than one value, Please look at DEMO.
Example: Table
Date...............List
12/1/2016 .... python, angularjs
13/1/2016..... java, html
data:
$scope.todolists = [{
date: '12/1/2016',
list: {python, angularjs}
}, {
date: '13/1/2016',
list: {java, html}
}];
view:
<tbody>
<tr ng-repeat="todolist in todolists" >
<td>{{todolist.date}}</td>
<td ng-repeat="list in todolist">{{subject}}</td>
</tr>
</tbody>
I tried ng-repeat inside ng-repeat but it is not working. So my question is how to insert more than one value in single cell in table.
Your references are wrong.
<tbody>
<tr ng-repeat="todolist in todolists" >
<td>{{todolist.date}}</td>
<td ng-repeat="list in todolist.list">{{list}}</td>
</tr>
</tbody>
or, preferably,
<tbody>
<tr ng-repeat="todolist in todolists" >
<td>{{todolist.date}}</td>
<td>
<span ng-repeat="list in todolist.list">
{{list + ($last ? "" : ", ") }}
</span>
</td>
</tr>
</tbody>
Your JSON is invalid. If you want to store values without properties, you need to use Array but not Object. Also, if the values are string you need to wrap them with comma like: ['val1', 'val2', ...];
You can do ng-repeat inside ng-repeat but you need to iterate the right property todolist.list.
You can't use {{subject}} if you have not property subject in you model. So you need to use {{list}} when you do the ng-repeat like ng-repeat="list in todolist.list".
The full code:
angular.module('app', []).
controller('ctrl', function($scope) {
$scope.todolists = [{ date: '12/1/2016', list: ['python', 'angularjs'] }, { date: '13/1/2016', list: ['java', 'html'] }];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<table>
<tr ng-repeat="todolist in todolists">
<td>{{todolist.date}}</td>
<td ng-repeat="list in todolist.list">{{list}}</td>
</tr>
</table>
</div>
Your datas are not properly declared. It should be:
$scope.todolists = [{
date: '12/1/2016',
list: [
'python',
'angularjs'
]
}, {
date: '13/1/2016',
list: [
'java',
'html'
]
}];
Note the '' around python, etc. and the list should be a list => [] and not {}.
A nice way to go is to write a custom filter:
angular.module("myApp", [])
.filter('nicelist', function() {
return function(input) {
if (input instanceof Array) {
return input.join(",");
}
return input;
}
});
Then, you can use :
<table>
<tr ng-repeat="todolist in todolists">
<td>{{todolist.date}}</td>
<td>{{todolist.list | nicelist}}</td>
</tr>
</table>
Here is a working fiddle.
I've seen so many ways to do this, but most are pretty old and I want to make sure I'm doing this correctly. Right now, the way I'm using isn't working and I feel like I'm missing something.
I'm getting the JSON back fine, I just need to get it to display in a table after I click the button.
Here is the JSON. This is how I'm going to get it from our server, I can't add any "var JSON =" or add any scope like "$scope.carrier" to the data, unless there's a way to add it after I've fetched the data.
{
"carrier":
[
{
"entity": "carrier",
"id": 1,
"parentEntity": "ORMS",
"value": "Medica"
}, {
"entity": "carrier",
"id": 2,
"parentEntity": "ORMS",
"value": "UHG"
}, {
"entity": "carrier",
"id": 3,
"parentEntity": "ORMS",
"value": "Optum"
}, {
"entity": "carrier",
"id": 4,
"parentEntity": "ORMS",
"value": "Insight"
}, {
"entity": "carrier",
"id": 5,
"parentEntity": "ORMS",
"value": "Insight"
}
]
}
Here is the app.js file to bring back the JSON data:
var app = angular.module('myTestApp', []);
app.controller('myController', ['$scope', '$http', function($scope, $http) {
var url = 'test.json';
$scope.clickButton = function() {
$http.get(url).success(function(data) {
console.log(data);
});
}
}]);
And then of course the HTML:
<div class="col-lg-12 text-center">
<button type=button class="btn btn-primary load" ng-click="clickButton()">Click!</button>
<table class="">
<tbody ng-repeat="carrier in carriers">
<tr>
<td>
<h3 class="">{{ module.entity }}</h3>
<h3 class="">{{ module.id }}</h3>
<h3 class="">{{ module.parentEntity }}</h3>
<h3 class="">{{ module.value }}</h3>
</td>
</tr>
</tbody>
</table>
</div>
I'm also wondering if I can use the ng-grid to put this in a table. I know they just upgraded it to ui grid so I'm not sure if this is still a feasible approach.
Also, I'm not getting errors, the data just won't display in the table right now. All I know is its returning the data properly, just not displaying in the table.
Any help is appreciated.
I looked at your plunker seems like you need to:
add angular script
wire the app and the controller
your variable in the repeater is wrong, I change it
take a look to this fixed plunker:
http://plnkr.co/edit/TAjnUCMOBxQTC6lNJL8j?p=preview
$scope.clickButton = function() {
$http.get(url).success(function(returnValue) {
alert(JSON.stringify(returnValue.carrier));
$scope.carriers = returnValue.carrier;
});
}
You never assign the value of the returned array to $scope.carriers.
At the line where you say console.log(data); add this:
$scope.carriers = data.data;
Here is the updated clickButton function (with a variable name change to reduce confusion):
$scope.clickButton = function() {
$http.get(url).success(function(returnValue) {
$scope.carriers = returnValue.data;
});
};
I'm having trouble accessing the nested JSON using the ng-repeat directives. I know it is working because the not nested part of the JSON object is displaying.
Here is a plunker of my code: http://plnkr.co/edit/V2iURMa8t7vG9AqDFMOf?p=preview
JavaScript:
var app = angular.module("app", [ ]);
app.controller("AppTest", function($scope){
$scope.currentInfo=[{"id":0,"article":"JavaScript Conquers the World","publisher":"Daily Times","meta_data":{"comments":4}},
{"id":1,"article":"The Problem with Foobar","publisher":"New York Times","meta_data":{"comments":27}}];
$scope.tableInfo=[{"name":"id","dataType":"Integer","isEditable":false},
{"name":"article","dataType":"String","isEditable":true},
{"name":"publisher","dataType":"String","isEditable":false},
{"name":"meta_data.comments","dataType":"Integer","isEditable":false}];
});
HTML:
<body ng-app="app" ng-controller="AppTest as app"
<table>
<tbody ng-repeat="anotherItem in currentInfo">
<tr>
<td ng-repeat="item in tableInfo">{{anotherItem[item.name]}}</td>
</tr>
</tbody>
</table>
</body>
Another solution that is better is to add function in the controller that will resolve the value for you. The issue with your solution is that you need Angular to resolve meta_data.comments, but it is treating it as the string that is used in the array lookup since it has already resolved item.name.
$scope.resolveLookup = function(object, lookup) {
var depth = lookup.split('.').length;
var currentObj = object;
for(var x=0; x<depth; x++) {
currentObj = currentObj[lookup.split('.')[x]];
}
return currentObj;
};
Then change the HTML to look like:
<td ng-repeat="item in tableInfo">{{resolveLookup(anotherItem,item.name)}}</td>
Here is the Plunker: http://plnkr.co/edit/RVd2ncwstyQtCtdhcC9U?p=preview
The issue is that it is putting 'metadata.comments' in the [] and it doesn't realize that it needs to be resolved again by angular. I can't think of fix without changing the data structure of your 'tableInfo' object.
Here is how I would do it.
Change table info to:
$scope.tableInfo = [{
"name": ["id"],
"dataType": "Integer",
"isEditable": false
}, {
"name": ["article"],
"dataType": "String",
"isEditable": true
}, {
"name": ["publisher"],
"dataType": "String",
"isEditable": false
}, {
"name": ["meta_data", "comments"],
"dataType": "Integer",
"isEditable": false
}];
Change your HTML to:
<td ng-repeat="item in tableInfo" ng-if="item.name.length==1">{{anotherItem[item.name[0]]}}</td>
<td ng-repeat="item in tableInfo" ng-if="item.name.length==2">{{anotherItem[item.name[0]][item.name[1]]}}</td>
Here is the Plunker: http://plnkr.co/edit/q9lHZ2TD7WZ74b2f6Ais?p=preview
I have following markup
<div ng-app>
<table ng-controller="test">
<tbody>
<tr ng-repeat="row in rows">
<td ng-repeat="col in cols">
<input type="text" ng-model="row[col].val" />
</td>
</tr>
</tbody>
</table>
</div>
controller looks like this
function test($scope) {
$scope.cols = ["col1", "col2", "col3"];
$scope.rows = [{
col1: { val: "x"}
}, {
col2: { val: "y" }
}]
}
When i try to set column value that does not yet exist, i get
"Cannot set property 'val' of undefined".
Example is here http://jsfiddle.net/z9NkG/2/
In documentation is note:
ngModel will try to bind to the property given by evaluating the
expression on the current scope. If the property doesn't already exist
on this scope, it will be created implicitly and added to the scope.
But it fails when using indexer instead of property name.
Is there a way to define ngModel expression dynamically or am i misusing angular?
And what about:
<input type="text" ng-model="row[col].val" ng-init="row[col] = row[col] || {}" />
Fiddle: http://jsfiddle.net/z9NkG/8/
I'm not sure about your model, but I think you are using a 2 dimensional array. I'm oversimplifying, not knowing,
make cols collection a child or rowsL
function test($scope) {
$scope.colnames = ["col1", "col2", "col3"];
$scope.rows = [{
cols: { col1: "x"}, { col2: "y"}
}, {
cols: { col1: "z"}, { col2: "a"}
}]
}
And then use nested ng-repeats
<table>
<tbody>
<tr ng-repeat="row in rows">
<td ng-repeat="col in row.cols">
<input type="text" ng-model="col.val" />
</td>
</tr>
</tbody>
</table>
The main problem is that you're setting an undefined property of an undefined object as the input's model. Angular does indeed automatically create the corresponding variables for your model binding, but to do so, you would have to bind the input directly to the row[col] property instead of row[col].val :
<input type="text" ng-model="row[col]" />
Here's the live demo: http://jsfiddle.net/z9NkG/9/
try this
make changes in controller
add below code
$scope.cols.forEach(function(x, y) {
angular.forEach($scope.rows, function(i, j) {
if ((i[x])== null)
i[x] = {};
});
})
yo can refer fiddle http://jsfiddle.net/z9NkG/10/
