I have a nested array of objects , so i am trying to display in table row only first 3 elements in array and after i am displaying remaining elements in array as a count (i.e +2).Now if i click on remain count i need to display all the elements in array on particular row click.
I am attaching the stack blitz URL for reference :- https://stackblitz.com/edit/primeng-chip-demo-agf8ey?file=src%2Fapp%2Fapp.component.html,src%2Fapp%2Fapp.component.ts
Please help me on these issue.
Thanks in advance
try this:
<p-chip
*ngFor="let cc of slice(c); let i = index"
[label]="cc.name"
></p-chip>
in .ts file
onChip(val: any) {
this.chips[val].extand = true;
}
slice(cc: any, index: number) {
if(cc?.extand) {
return cc.values;
}
return cc.values.slice(1,3);
}
also add to every object extand: false
chips = [
{
id: 1,
values: [
{
name: 'one',
},
{
name: 'two',
},
{
name: 'three',
},
{
name: 'four',
},
{
name: 'five',
},
],
extand: false
},]
Create a template variable:
<h5>Basic</h5>
<div class="p-d-flex p-ai-center">
<table>
<tr>
<th>Id</th>
<th>Chips</th>
</tr>
<tr *ngFor="let c of chips; let val = index">
<td>{{ c.id }}</td>
<td #myCell>
<ng-container *ngIf="myCell.showAll">
<p-chip *ngFor="let cc of c.values" [label]="cc.name"></p-chip>
</ng-container>
<ng-container *ngIf="!myCell.showAll">
<p-chip
*ngFor="let cc of c.values | slice: 0:3"
[label]="cc.name"
></p-chip>
<p-chip
styleClass="chipMore"
*ngIf="c.values.length >= 3"
(click)="myCell.showAll = !myCell.showAll"
>+{{ c.values.length - 3 }}</p-chip
>
</ng-container>
</td>
</tr>
</table>
</div>

I get a nested JSON object back from an API call that looks something along the lines of this:
{
"name": “Main “Folder”,
"children": [
{
"name": “Child Folder 1”,
"children": []
},
{
"name": “Child Folder 2”,
"children": [
{
"name": “Sub Folder 1”,
"children": [
{
“name”: “Sub Sub Folder 1”,
“children”: []
}
]
},
{
"name": “Sub Folder 2” ,
"children": []
}
]
}
]
}
There is no limit on how far the JSON object can be nested so that is unknown to me. I need to have all of the children of the folders to be indented under the parent in the table. I'm not really even sure how to go about doing this. The first thing I tried was doing something like this in my HTML file, but I quickly realized it wasn't going to work.
folders.html
<table>
<thead>
<tr><strong>{{ this.tableData.name }}</strong></tr>
</thead>
<tbody ng-repeat="b in this.tableData.children">
<tr>
<td>{{ b.name }}</td>
<td ng-repeat="c in b.children">{{ c.name }}</td>
</tr>
</tbody>
</table>
folders.js
export default class FoldersController {
constructor($rootScope, $scope, $uibModal) {
this.tableData = {Example Data from top}
}
}
Is there a not too complicated way to go about doing this? Thanks!
You should create a component with a template that contains a table, then you can nest your component inside itself to follow the tree structure logical path:
Your root controller should contain your table data:
angular.module('app').controller('RootCtrl', ['$scope', function($scope) {
// assigning the data to $scope to make it available in the view
$scope.tableData = {Example Data from top};
}]);
Your tree component could be something on this lines:
angular.module('app').component('treeComponent', {
controller: 'TreeCtrl',
bindings: {
tree: '<',
},
templateUrl: 'tree-view.html'
});
your root template should load the first instance of the component:
<div>
<tree-component tree="tableData"></tree-component>
</div>
then the component template should take care of the the recursion when required;
tree-view.html:
<table class="record-table">
<thead>
<tr>
<th>
<strong>{{ $ctrl.tableData.name }}</strong>
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="node in $ctrl.tableData.children">
<td>{{node.name}}</td>
<td ng-if="node.children.length > 0">
<tree-component tree="node.children"></tree-component>
</td>
</tr>
</tbody>
</table>
creating indentation then becomes easy using basic css:
.record-table .record-table {
padding-left: 20px
}
I was able to figure out a solution of my own using recursion in the js file. I implemented mindthefrequency's answer as well and it seems to be working just fine. I'm marking it as the best answer because it seems to be the cleaner solution, but I'm posting what I have in case someone wants to take a more js oriented approach.
First, in the js file, use recursion to add all of the nodes and how far each needs to be indented to the table data variable.
folders.js
export default class FoldersController {
constructor($rootScope, $scope, $uibModal) {
this.resp = {Example Data from top}
this.tableData = []
this.createTable(this.resp.children, 0, [
{
name: this.resp.name,
indent: '0px',
},
]);
}
createTable(children, count, data) {
count += 1;
// base case
if (!children || children.length === 0) {
return;
}
for (const child of children) {
const { name } = child;
const returnData = data;
returnData.push({
name: name,
indent: `${count * 25}px`,
});
this.tableData = returnData;
this.createTable(child.children, count, returnData);
}
}
}
Then, in the html file, use angularjs to properly indent each node
folders.html
<table>
<thead>
<tr><strong>Table Header</strong></tr>
</thead>
<tbody ng-repeat="b in vm.tableData">
<tr>
<td ng-style="{'padding-left': b.indent}">{{ b.name }}</td>
</tr>
</tbody>
</table>
API data {
id: 1,
date: "21/may/2020",
name: "Server A",
geo: "Europa",
status: "online"
}
ngOnInit {
this.col = [
{field: 'name', header: 'Server Name'},
{field: 'geo', header: 'Geography'},
{field: 'status', header: 'Status'},
{field: 'date', header: 'Date'}
]
}
I'm testing angular PrimeNG and I have an data-table, where I set the values for each table row manually, it works fine.
template
<ng-template>
<td>
<tr>
<td>{{rowData.name}}</td>
<td>{{rowData.geo}}</td>
<td>{{rowData.status}}</td>
<td>{{rowData.date | date: 'dd/MMM/yyyy'}}</td>
</tr>
<td>
<ng-template>
I updated my template to dynamically loop through the object and set the data, how can I update my loop so I can insert the pipe when I render the "date" object.
<td *ngFor="let col of column">
{{rowData[col.field]}}
</td>
The above {{rowData[col.field]}} is working, but I not sure how to inside *ngFor="let col of columns " I can update only the col.date and add pipe into it.
This is what I trying but not successful, the baove is working but not the Pipe and also if I add keyvalue the tables data is not being displayed anymore.
<td *ngFor="let col of columns | keyvalue">
<ng-container *ngIf="rowData[col.field] !== 'date'"> {{rowData[col.field]}}</ng-container>
<ng-container *ngIf="rowData[col.field] === 'date'"> {{rowData[col.field] | date: 'dd/MMM/yyyy'}}</ng-container>
</td>
Any suggestion or example I can look into?
If i understand your question right, you want to apply pipe on the birthdate field, so you can do ,
<td *ngFor="let data of object">
{{data["birthdate"] | date: 'dd/MMM/yyyy' }}
</td>
Use key value pipe like
<td *ngFor="let data of object | keyvalue">
<ng-container *ngIf="data.key !== 'birthdate'"> {{data.value}}</ng-container>
<ng-container *ngIf="data.key === 'birthdate'"> {{data.value | date: 'dd/MMM/yyyy'}}</ng-container>
</td>
Basically I'm making a todo list with angular and I want to display the how many items have been marked as done I have an array object of Lists and each list has a collection of list items called todos like so:
[{listName: "ESSENTIALS", newTodoName:"", newTodoQ:"0", todos: [
{ taskName : "Comb" , quantity: 1, isDone : false , id: "comb" } ]},
{listName: "TOILETRIES", newTodoName:"", newTodoQ:"0", todos: [
{ taskName : "Tooth Brush" , quantity: 1, isDone : false , id: "toothbrush"},
{ taskName : "Tooth paste" , quantity: 6, isDone : false, id: "toothpaste" },
{ taskName : "Deodorant" , quantity: 3, isDone : false, id: "deodorant" }
]}];
So I have two ng-repeats.. One repeats the Lists then another inside of it prints out each list item. I have an H1 and next to the title I want to have the the items that were marked isDone as true next to the total amount of records to show how many items you have left. As you can see I started to code up a filter but I believe it's wrong I keep getting: "Syntax Error: Token 'undefined' is unexpected, expecting [}] at column null of the expression [ (list.todos |] starting at [{4}]." which I'm not really sure what that means...my fourth item is blank? Yet I have all my todos there and they are not blank. Is my filter wrong? or a better way to do this?
<div class='row' ng-repeat="list in lists">
<h1 class='centerTitle'>{{list.listName}} <span class="listCounter"> {{ (list.todos | filter:{todos: {isDone: true}}: true).length }} / {{list.todos.length}}</span></h1>
<ul ui-sortable="todoSortable" ng-model="list.todos">
<li ng-class="{taskDone: todo.isDone}" class="todoTask" ng-repeat="todo in list.todos | orderBy: 'isDone' "></li>
<div>
Can you try:
<h1 class='centerTitle'>{{list.listName}} <span class="listCounter"> {{ (list.todos | filter: {isDone: true}).length }} / {{list.todos.length}}</span></h1>
My goal is to apply a formatting filter that is set as a property of the looped object.
Taking this array of objects:
[
{
"value": "test value with null formatter",
"formatter": null,
},
{
"value": "uppercase text",
"formatter": "uppercase",
},
{
"value": "2014-01-01",
"formatter": "date",
}
]
The template code i'm trying to write is this:
<div ng-repeat="row in list">
{{ row.value | row.formatter }}
</div>
And i'm expecting to see this result:
test value with null formatter
UPPERCASE TEXT
Jan 1, 2014
But maybe obviusly this code throws an error:
Unknown provider: row.formatterFilterProvider <- row.formatterFilter
I can't immagine how to parse the "formatter" parameter inside the {{ }}; can anyone help me?

The | is an angular construct that finds a defined filter with that name and applies it to the value on the left. What I think you need to do is create a filter that takes a filter name as an argument, then calls the appropriate filter (fiddle) (adapted from M59's code):
HTML:
<div ng-repeat="row in list">
{{ row.value | picker:row.formatter }}
</div>
Javascript:
app.filter('picker', function($filter) {
return function(value, filterName) {
return $filter(filterName)(value);
};
});
Thanks to #karlgold's comment, here's a version that supports arguments. The first example uses the add filter directly to add numbers to an existing number and the second uses the useFilter filter to select the add filter by string and pass arguments to it (fiddle):
HTML:
<p>2 + 3 + 5 = {{ 2 | add:3:5 }}</p>
<p>7 + 9 + 11 = {{ 7 | useFilter:'add':9:11 }}</p>
Javascript:
app.filter('useFilter', function($filter) {
return function() {
var filterName = [].splice.call(arguments, 1, 1)[0];
return $filter(filterName).apply(null, arguments);
};
});
I like the concept behind these answers, but don't think they provide the most flexible possible solution.
What I really wanted to do and I'm sure some readers will feel the same, is to be able to dynamically pass a filter expression, which would then evaluate and return the appropriate result.
So a single custom filter would be able to process all of the following:
{{ammount | picker:'currency:"$":0'}}
{{date | picker:'date:"yyyy-MM-dd HH:mm:ss Z"'}}
{{name | picker:'salutation:"Hello"'}} //Apply another custom filter
I came up with the following piece of code, which utilizes the $interpolate service into my custom filter. See the jsfiddle:
Javascript
myApp.filter('picker', function($interpolate ){
return function(item,name){
var result = $interpolate('{{value | ' + arguments[1] + '}}');
return result({value:arguments[0]});
};
});
One way to make it work is to use a function for the binding and do the filtering within that function. This may not be the best approach: Live demo (click).
<div ng-repeat="row in list">
{{ foo(row.value, row.filter) }}
</div>
JavaScript:
$scope.list = [
{"value": "uppercase text", "filter": "uppercase"}
];
$scope.foo = function(value, filter) {
return $filter(filter)(value);
};
I had a slightly different need and so modified the above answer a bit (the $interpolate solution hits the same goal but is still limited):
angular.module("myApp").filter("meta", function($filter)
{
return function()
{
var filterName = [].splice.call(arguments, 1, 1)[0] || "filter";
var filter = filterName.split(":");
if (filter.length > 1)
{
filterName = filter[0];
for (var i = 1, k = filter.length; i < k; i++)
{
[].push.call(arguments, filter[i]);
}
}
return $filter(filterName).apply(null, arguments);
};
});
Usage:
<td ng-repeat="column in columns">{{ column.fakeData | meta:column.filter }}</td>
Data:
{
label:"Column head",
description:"The label used for a column",
filter:"percentage:2:true",
fakeData:-4.769796600014472
}
(percentage is a custom filter that builds off number)

Here is how I used it.
$scope.table.columns = [{ name: "June 1 2015", filter: "date" },
{ name: "Name", filter: null },
] etc...
<td class="table-row" ng-repeat="column in table.columns">
{{ column.name | applyFilter:column.filter }}
</td>
app.filter('applyFilter', [ '$filter', function( $filter ) {
return function ( value, filterName ) {
if( !filterName ){ return value; } // In case no filter, as in NULL.
return $filter( filterName )( value );
};
}]);
I improved #Jason Goemaat's answer a bit by adding a check if the filter exists, and if not return the first argument by default:
.filter('useFilter', function ($filter, $injector) {
return function () {
var filterName = [].splice.call(arguments, 1, 1)[0];
return $injector.has(filterName + 'Filter') ? $filter(filterName).apply(null, arguments) : arguments[0];
};
});
The newer version of ng-table allows for dynamic table creation (ng-dynamic-table) based on a column configuration. Formatting a date field is as easy as adding the format to your field value in your columns array.
Given
{
"name": "Test code",
"dateInfo": {
"createDate": 1453480399313
"updateDate": 1453480399313
}
}
columns = [
{field: 'object.name', title: 'Name', sortable: 'name', filter: {name: 'text'}, show: true},
{field: "object.dateInfo.createDate | date :'MMM dd yyyy - HH:mm:ss a'", title: 'Create Date', sortable: 'object.dateInfo.createDate', show: true}
]
<table ng-table-dynamic="controller.ngTableObject with controller.columns" show-filter="true" class="table table-condensed table-bordered table-striped">
<tr ng-repeat="row in $data">
<td ng-repeat="column in $columns">{{ $eval(column.field, { object: row }) }}</td>
</tr>
</table>
I ended up doing something a bit more crude, but less involving:
HTML:
Use the ternary operator to check if there is a filter defined for the row:
ng-bind="::data {{row.filter ? '|' + row.filter : ''}}"
JS:
In the data array in Javascript add the filter:
, {
data: 10,
rowName: "Price",
months: [],
tooltip: "Price in DKK",
filter: "currency:undefined:0"
}, {
This is what I use (Angular Version 1.3.0-beta.8 accidental-haiku).
This filter allows you to use filters with or without filter options.
applyFilter will check if the filter exists in Angular, if the filter does not exist, then an error message with the filter name will be in the browser console like so...
The following filter does not exist: greenBananas
When using ng-repeat, some of the values will be undefined. applyFilter will handle these issues with a soft fail.
app.filter( 'applyFilter', ['$filter', '$injector', function($filter, $injector){
var filterError = "The following filter does not exist: ";
return function(value, filterName, options){
if(noFilterProvided(filterName)){ return value; }
if(filterDoesNotExistInAngular(filterName)){ console.error(filterError + "\"" + filterName + "\""); return value; }
return $filter(filterName)(value, applyOptions(options));
};
function noFilterProvided(filterName){
return !filterName || typeof filterName !== "string" || !filterName.trim();
}
function filterDoesNotExistInAngular(filterName){
return !$injector.has(filterName + "Filter");
}
function applyOptions(options){
if(!options){ return undefined; }
return options;
}
}]);
Then you use what ever filter you want, which may or may not have options.
// Where, item => { name: "Jello", filter: {name: "capitalize", options: null }};
<div ng-repeat="item in items">
{{ item.name | applyFilter:item.filter.name:item.filter.options }}
</div>
Or you could use with separate data structures when building a table.
// Where row => { color: "blue" };
// column => { name: "color", filter: { name: "capitalize", options: "whatever filter accepts"}};
<tr ng-repeat="row in rows">
<td ng-repeat="column in columns">
{{ row[column.name] | applyFilter:column.filter.name:column.filter.options }}
</td>
</tr>
If you find that you require to pass in more specific values you can add more arguments like this...
// In applyFilter, replace this line
return function(value, filterName, options){
// with this line
return function(value, filterName, options, newData){
// and also replace this line
return $filter(filterName)(value, applyOptions(options));
// with this line
return $filter(filterName)(value, applyOptions(options), newData);
Then in your HTML perhaps your filter also requires a key from the row object
// Where row => { color: "blue", addThisToo: "My Favorite Color" };
// column => { name: "color", filter: { name: "capitalize", options: "whatever filter accepts"}};
<tr ng-repeat="row in rows">
<td ng-repeat="column in columns">
{{ row[column.name] | applyFilter:column.filter.name:column.filter.options:row.addThisToo }}
</td>
</tr>
