I'm looking for a way to add rows to a table. My data structure looks like that:
rows = [
{ name : 'row1', subrows : [{ name : 'row1.1' }, { name : 'row1.2' }] },
{ name : 'row2' }
];
I want to create a table which looks like that:
table
row1
row1.1
row1.2
row2
Is that possible with angular js ng-repeat? If not, what would be a "angular" way of doing that?
Edit:
Flatten the array would be a bad solution because if i can iterate over the sub elements i could use different html tags inside the cells, other css classes, etc.
More than one year later but found a workaround, at least for two levels (fathers->sons).
Just repeat tbody's:
<table>
<tbody ng-repeat="row in rows">
<tr>
<th>{{row.name}}</th>
</tr>
<tr ng-repeat="sub in row.subrows">
<td>{{sub.name}}</td>
</tr>
</tbody>
</table>
As far as I know all browsers support multiple tbody elements inside a table.
More than 3 years later, I have been facing the same issue, and before writing down a directive I tried this out, and it worked well for me :
<table>
<tbody>
<tr ng-repeat-start="row in rows">
<td>
{{ row.name }}
</td>
</tr>
<tr ng-repeat-end ng-repeat="subrow in row.subrows">
<td>
{{ subrow.name }}
</td>
</tr>
</tbody>
</table>
You won't be able to do this with ng-repeat. You can do it with a directive, however.
<my-table rows='rows'></my-table>
Fiddle.
myApp.directive('myTable', function () {
return {
restrict: 'E',
link: function (scope, element, attrs) {
var html = '<table>';
angular.forEach(scope[attrs.rows], function (row, index) {
html += '<tr><td>' + row.name + '</td></tr>';
if ('subrows' in row) {
angular.forEach(row.subrows, function (subrow, index) {
html += '<tr><td>' + subrow.name + '</td></tr>';
});
}
});
html += '</table>';
element.replaceWith(html)
}
}
});
I'm a bit surprised that so many are advocating custom directives and creating proxy variables being updated by $watch.
Problems like this are the reason that AngularJS filters were made!
From the docs:
A filter formats the value of an expression for display to the user.
We aren't looking to manipulate the data, just format it for display in a different way. So let's make a filter that takes in our rows array, flattens it, and returns the flattened rows.
.filter('flattenRows', function(){
return function(rows) {
var flatten = [];
angular.forEach(rows, function(row){
subrows = row.subrows;
flatten.push(row);
if(subrows){
angular.forEach(subrows, function(subrow){
flatten.push( angular.extend(subrow, {subrow: true}) );
});
}
});
return flatten;
}
})
Now all we need is to add the filter to ngRepeat:
<table class="table table-striped table-hover table-bordered">
<thead>
<tr>
<th>Rows with filter</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in rows | flattenRows">
<td>{{row.name}}</td>
</tr>
</tbody>
</table>
You are now free to combine your table with other filters if desired, like a search.
While the multiple tbody approach is handy, and valid, it will mess up any css that relies on the order or index of child rows, such as a "striped" table and also makes the assumption that you haven't styled your tbody in a way that you don't want repeated.
Here's a plunk: http://embed.plnkr.co/otjeQv7z0rifPusneJ0F/preview
Edit:I added a subrow value and used it in the table to show which rows are subrows, as you indicated a concern for being able to do that.
Yes, it's possible:
Controller:
app.controller('AppController',
[
'$scope',
function($scope) {
$scope.rows = [
{ name : 'row1', subrows : [{ name : 'row1.1' }, { name : 'row1.2' }] },
{ name : 'row2' }
];
}
]
);
HTML:
<table>
<tr ng-repeat="row in rows">
<td>
{{row.name}}
<table ng-show="row.subrows">
<tr ng-repeat="subrow in row.subrows">
<td>{{subrow.name}}</td>
</tr>
</table>
</td>
</tr>
</table>
Plunker
In case you don't want sub-tables, flatten the rows (while annotating subrows, to be able to differentiate):
Controller:
function($scope) {
$scope.rows = [
{ name : 'row1', subrows : [{ name : 'row1.1' }, { name : 'row1.2' }] },
{ name : 'row2' }
];
$scope.flatten = [];
var subrows;
$scope.$watch('rows', function(rows){
var flatten = [];
angular.forEach(rows, function(row){
subrows = row.subrows;
delete row.subrows;
flatten.push(row);
if(subrows){
angular.forEach(subrows, function(subrow){
flatten.push( angular.extend(subrow, {subrow: true}) );
});
}
});
$scope.flatten = flatten;
});
}
HTML:
<table>
<tr ng-repeat="row in flatten">
<td>
{{row.name}}
</td>
</tr>
</table>

Here is an example. This code prints all names of all the people within the peopeByCity array.
TS:
export class AppComponent {
peopleByCity = [
{
city: 'Miami',
people: [
{
name: 'John', age: 12
}, {
name: 'Angel', age: 22
}
]
}, {
city: 'Sao Paulo',
people: [
{
name: 'Anderson', age: 35
}, {
name: 'Felipe', age: 36
}
]
}
]
}
HTML:
<div *ngFor="let personsByCity of peopleByCity">
<div *ngFor="let person of personsByCity.people">
{{ person.name }}
</div>
</div>

Have been task to have a look at a Vue app (gulp....react dev here) for a colleague that left the company. However it is built with a string that renders the table data in a for loop such as this:
var table = "";
for (var i = 0; i < companies.length; i++) {
table += "<tr>";
table += `<td id="checkUpdateBox"><input onClick=${this.updateSomeCompanies(companies[i].id)}
type="checkbox"/></td>`;
table += `<td>${companies[i].id}</td>`;
table += `<td>${companies[i].name}</td>`;
table += `<td>${companies[i].custom_fields.seno}</td>`;
table += `<td>${companies[i].created_at}</td>`;
table += "</tr>";
}
methods: {
updateSomeCompanies(id) {
console.log(id);
},
// next method and so on
Am trying to do an update based on the id of the company. Right now, I am just console.logging the id on the method updateSomeCompanies.
However, when the page is loading I am getting the id of the company in the console even though the checkbox haven't been clicked, how come it works like this, is the strange string loop that build the tabledata or am something strange in the code above?
Furthermore, when clicking the checkbox nothing happens?
Have tried with the v-on:clicked and the #Click (same results as above).
Console.logs all of the id's then checkbox do not work.
Suggestions :
As you are using Vue.js then no need to use Vanilla JS to create a table. You can do it dynamically in the template itself.
Use #click/v-on:click directive of Vue to trigger the click event instead of JS onClick.
Live Demo :
new Vue({
el: '#app',
data: {
message: 'Hello Vue.js!',
companies: [{
id: 1,
name: 'Alpha',
created_at: 'test'
}, {
id: 2,
name: 'Beta',
created_at: 'test'
}, {
id: 3,
name: 'Gamma',
created_at: 'test'
}]
},
methods: {
updateSomeCompanies(id) {
console.log(id);
}
}
})
table, th, td {
border: 1px solid black;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

I've populated a table with data from a JSON file, and then when the user clicks on an item in the table, a container and it's fields display below and it SHOULD be populated with that specific data, though it isn't.
The function select is invoked through list-patents.htm which contains the table with a list of patents. I have used the $rootScope object so the function is accessible from multiple controllers i.e. patentDetailsCtrl
Why isn't my table in patent-item.htm being populated with the ng-repeat directive?
var app = angular.module('myApp', ['ngRoute', 'angularMoment', 'ui.router', "chart.js"]);
$stateProvider
.state("patents.list.item", {
url: "/patent-item",
templateUrl: "templates/patents/list/patent-item.htm",
params: {
id: null,
appNo: null,
clientRef: null,
costToRenew: null,
renewalDueDate: null,
basketStatus: null,
costBandEnd: null,
nextStage: null
},
controller: "patentDetailsCtrl"
})
app.run(function($rootScope) {
$rootScope.select = function() {
return $rootScope.patentItem = item;
}
});
app.controller('patentDetailsCtrl', ['$scope', '$http', function($scope, $http) {
$scope.selectedPatent = $scope.patentItem;
console.log($scope.selectedPatent);
}]);
list-patents.htm
<tbody>
<tr ng-repeat="x in patents">
<td ng-click="select(x)"><a ui-sref="patents.list.item({id: x.id, appNo: x.applicationNumber, clientRef: x.clientRef, costToRenew: x.costToRenew, renewalDueDate: x.renewalDueDate, basketStatus: x.basketStatus, costBandEnd: x.costBandEnd, nextStage: x.nextStage})">{{x.applicationNumber}}</a></td>
<td ng-bind="x.clientRef"></td>
<td ng-bind="x.costToRenew">$</td>
<td ng-bind="x.renewalDueDate"></td>
<td><button type="button" class="btn btn-danger" ng-click="remove(x.id)">Remove</button></td>
</tr>
</tbody>
patent-item.htm
<table>
<tbody>
<thead>
<tr>
<td>applicationNumber</td>
<td>clientRef</td>
<td>costToRenew</td>
<td>renewalDueDate</td>
<td>basketStatus</td>
<td>costBandEnd</td>
<td>nextStage</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in selectedPatent">
<td>{{x.applicationNumber}}</td>
<td>{{x.clientRef}}</td>
<td>{{x.costToRenew}}</td>
<td>{{x.renewalDueDate}}</td>
<td>{{x.basketStatus}}</td>
<td>{{x.costBandEnd}}</td>
<td>{{x.nextStage}}</td>
</tr>
</tbody>
</table>
</tbody>
You need to correct below points:
your $rootScope.select() method doesn't accept data (select(x)) passed from your list-patents.htm, So put item as param.,
Like : $rootScope.select = function(item) { \\ code
Sine you do ng-repeat on $rootScope.patentItem, then I guess you need to make it array, and push the passed data to it. (No need of return statement as well.)
So run block should be like :
app.run(function($rootScope) {
rootScope.patentItem = [];
$rootScope.select = function(item) {
$rootScope.patentItem.push(item);
}
});
See this Example Fiddle
To me it seems like you're trying to access the patentItem selected in your select function. If you're passing it to the $rootScope this way, you will also need to access it this way.
So change the line as follows...
$scope.selectedPatent = $rootScope.patentItem
I want to match headfield values with datafield, and have to fetch corresponding value into table data.
HTML:
<table>
<thead>
<tr>
<th ng-repeat="ReportsHead in ReportsHeadList">
{{ReportsHead.headerfield = ReportsHead.headfield}}
</th>
</tr>
</thead>
<tbody>
<tr>
<td ng-repeat="ReportsData in ReportsDataList"
ng-if="ReportsHead.headerfield == ReportsData.datafield">
{{ReportsData.value}}
</td>
</tr>
</tbody>
</table>
JSON Data :
$scope.ReportsHeadList = [
{
'headfield':'Contact Name'
},
{
'headfield':'Phone'
},
{
'headfield':'Email'
}
];
$scope.ReportsDataList = {
[
{
'datafield':'Contact Name',
'value':'Gunaseelan'
},
{
'datafield':'Phone',
'value':'8122911043'
},
{
'datafield':'Email',
'value':'G#gmail.com'
}
],
[
{
'datafield':'Contact Name',
'value':'Gunaseelan'
},
{
'datafield':'Phone',
'value':'8122911043'
},
{
'datafield':'Email',
'value':'G#gmail.com'
}
]
};
Thanks in advance.
First you should parse your Json with JSON.parse(json), and assigment the result to variable. e.g:
$scope.json = JSON.parse(json).
After, you can check for match headfield and data fields with for loop or map, e.g:
for(i in headfield) {
if (i === something)
return i
}
Hope the answar will help, if not leave a comment,
Good luck!
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.
In my angular app I'm trying to display JSON data in a table. The data looks like this:
$scope.data =
{
"EVENT NAME":"Free Event",
"ORDER ID":311575707,
"DATE":"6/26/14",
"GROSS REVENUE (USD)":"0",
"TICKET REVENUE (USD)":"0",
"EVENTBRITE FEES (USD)":"0",
"CC PROCESSING (USD)":"0",
"TICKETS":1,
"TYPE":"Free Order",
"STATUS":"Free Order",
"TRANSACTION ID":"",
"NOTES":"",
"FIRST NAME":"Khee Seng",
"LAST NAME":"Chua",
"EMAIL ADDRESS":"email#anemailadderss.com"
};
And I'm displaying it like this:
<table class="table table-striped selector">
<tbody>
<tr>
<td ng-repeat="(key, value) in data">
<strong>{{key}}</strong>
</td>
</tr>
<tr>
<td ng-repeat="(key, value) in data">
{{value}}
</td>
</tr>
</tbody>
</table>
In my mind this should go through each `(key, value) pair in the object and display it in order. However, AngularJS displays the values in alphabetical order.
Here's a plunkr which replicates this issue: http://plnkr.co/edit/V3Y2ZuwV1v9Pzsl0jGhA?p=preview
How can I tweak the code so it displays in the natural order that the object actually comes in?
You can achieve it like this
Working Demo
In the scope define a method like as shown
$scope.notSorted = function(obj){
if (!obj) {
return [];
}
return Object.keys(obj);
}
and in html like as shown below
html
<table class="table table-striped selector">
<tbody>
<tr>
<th ng-repeat="key in notSorted(data)">
{{key}}
</th>
</tr>
<tr>
<td ng-repeat="key in notSorted(data)" ng-init="value = data[key]">
{{value}}
</td>
</tr>
</tbody>
</table>
Original Article: ng-repeat with no sort? How?
A Javascript object does not have the concept of 'natural order' of its keys:
Definition of an Object from ECMAScript Third Edition (here):
4.3.3 Object
An object is a member of the type Object. It is an unordered collection of properties
each of which contains a primitive value, object, or function [...]
You probably should change a bit your data structure...
For example:
$scope.data =
{
1: { "EVENT NAME": "Free Event" },
2: { "ORDER ID": 311575707 },
/* ... */
};
And then use the numerical key to sort your items...
Object properties don't have a natural order.
You can achieve what you're looking for with a slightly different Object:
$scope.data =
{
columns: [
{
"EVENT NAME":"Free Event",
"priority": 0
},
{
"ORDER_ID":311575707,
"priority": 1
},
...
]
}
