Angular loop through table row and check for checked checbox - angularjs

I have a table that has a list from database with checkbox on each row, checkbox will used for ex. during deletion of the record.
So what i am trying to achieve is that when i clicked the delete button, angular will loop each row in table and check the checkbox whether is checked, if yes the please proceed to delete. Dont have any idea how to do this. Someone please give some related example.
Here is my code
index.html
<button class="ui red labeled icon button right floated" type="button" data-content="Delete selected item(s)" id="delete" ng-click="deleteSeleted()"><i class="trash icon"></i>Delete</button>
<div class='container-table'>
<table class="ui fixed single line celled table striped sortable compact" style="width:2000px" id="mytable">
<thead>
<tr>
<th class="width-checkbox"><input type="checkbox" ng-model="matin.selectedAll" /></th>
<th class="width-120">Item</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in data">
<td><input type="checkbox" ng-checked="matin.selectedAll"></td>
<td>{{x.item}}</td>
</tr>
</tbody>
</table>
</div>

<tr ng-repeat="x in data">
<td><input type="checkbox" ng-model="x.selected"></td>
<td>{{x.item}}</td>
</tr>
Angular Js Code
for (var k = 0; k < $scope.data.length; k++)
{
if($scope.data[k].selected==true)
{
//Perform your desired thing over here
var val=$scope.data[k].item //to getData
}
}

Please find the fiddler link which i have created to select all the items in the table and on delete print which ever is checked https://jsfiddle.net/dfL1L944/3/
var appModule = angular.module('Module', []);
appModule.controller("DataController", function($scope) {
$scope.data = [{"name":"Alex"},{"name":"Juni"}]
$scope.deleteAll = false;
$scope.deleteSeleted = function(){
$scope.data.forEach(function(x) {
console.log(x.name);
});
}
$scope.selectedAll = function(){
$scope.data.forEach(function(x) {
if($scope.deleteAll){
x.deleted = true;
}
else{
x.deleted = false;
}
});
}
});
HTML Code
<div ng-app="Module"> <div ng-controller="DataController">
<button class="ui red labeled icon button right floated" type="button" data-content="Delete selected item(s)" id="delete" ng-click="deleteSeleted()"> <i class="trash icon"></i>Delete</button> <div class='container-table'> <table class="ui fixed single line celled table striped sortable compact" style="width:200px" id="mytable"> <thead>
<tr>
<th width="20px">
<input type="checkbox" ng-model="deleteAll" ng-click="selectedAll()" /></th>
<th>Item</th>
</tr> </thead> <tbody>
<tr ng-repeat="x in data">
<td width="2px"><input type="checkbox" ng-checked="x.deleted"></td>
<td>{{x.name}}</td>
</tr> </tbody> </table> </div>
</div> </div>

You could use $filter (you would need to insert $filter as a dependency)
$scope.data: [ // assuming your model looks like this
{
Id: "my_id",
Name: "my_name",
checked: true
}
];
var myFilteredValues = $filter('filter')($scope.data, { $: true });
And in your HTML
<tr ng-repeat="x in data">
<td><input type="checkbox" ng-model="x.checked"></td>
<td>{{x.Name}}</td>
</tr>

You can add a .toDelete property to every x in your data array, for example, and bind the checkboxes like this:
<input type="checkbox" ng-model="x.toDelete">
Afterwards you can create a button under the table:
<input type="button" ng-click="deleteRows();" value="Delete rows">
...And then create a function on your controller's scope (a newbie-friendly function):
$scope.deleteRows = function(){
var i=0;
for(i=0; i<data.length; i++){
if(data[i].toDelete){
//send your server requests here and do
//your stuff with the element if needed
data.splice(i, 1); //remove the element from the array
i--; //decrement the value of i so it stays the same
//(array is now shorter than it used to be)
}
}
}
You can also keep the information on what row is to be deleted in a separate array on the same scope but this solution seems simpler to me.
Regarding the "Check All" checkbox at the top, you can create a function and bind it with ng-click to a button or any other element and use that function to simply iterate through all the elements and set the .toDelete property to true for each one of them.

how can I keep some values in a ngshow and ng hide variable so that $digest does not initialize them again and again in angularjs?

I am displaying some data in a web app that I am getting from a SQL database using a http service. I want to be able to modify the information of that data on the same table where the data is shown. I am using angularjs and I am using the directives ng-show and ng-hide on the table. Here I show the part of the code I am talking about.
<table>
<tr>
<td><font size = 4>Servicio: </font> </td>
<td> </td>
<td>
<select class="col-sm-12" name="repeatSelect" id="repeatSelect" ng-model="currentItem.ServicioId">
<option ng-repeat="option in items.Servicio" value="{{option.Id}}"> {{option.Nombre}}</option>

On my controller I am using object arrays to get the information from the databases and I am using a mirror array to keep the boolean values of the data shown on the table, so depending on the boolean value the tables shows the data or get an input for the user to modify the data.
I get the mirror array once I know the service and client related to the data I want to show and which is possible to be modified.
However, when I click on the button to modify the status of the ng-hide or ng-show object named editingData, the controllers modifies it, but the $digest run all the other functions related to the bindings of the view and returns the bool object array to its inital values.
I haven´t been able to find away to go around this normal working way of the $digest and $watches so my $editingData object is not modified to its initial values. Here I show the code of the controller related to this.
angular.module("App")
.controller("ConceptoCtrl", function ($scope, $http, $resource, serviciosConceptoFactory, serviciosConceptoTipoFactory, serviciosFactory, clientesFactory) {
$scope.list = function () {
$scope.items = serviciosConceptoFactory.query();
$scope.itemsT = serviciosConceptoTipoFactory.query();
$scope.items.ServicioConceptoTipo = $scope.itemsT;
$scope.itemsS = serviciosFactory.query();
$scope.items.Servicio = $scope.itemsS;
$scope.itemsC = clientesFactory.query();
$scope.itemsS.Cliente = $scope.itemsC;
}
//some other functions
$scope.editingData = {};
$scope.getitemsSC = function (item) {
$scope.itemsSC = [];
for (var j = 0; j < $scope.items.length; j++) {
if ($scope.items[j].ServicioId == item) {
newitem = $scope.items[j];
$scope.itemsSC.push(newitem);
}
}
for (var i = 0; i < $scope.itemsSC.length; i++) {
$scope.editingData[$scope.itemsSC[i].Id] = false;
}
}
$scope.editOrCreate = function (item) {
$scope.currentItem = item;
$scope.editingData[item.Id] = true;
}
$scope.list();
});
The {{getNameC(currentItem.ServicioId}} function shown on the html file is the one that calls the $scope.getItemsSC(item) function once it knows the services and client related to the data that will be shown and it is this function the one that initializes the boolean values for the $scope.editingData mirror array depending on the Id of the item.
The $scope.editOrCreate(item) function is the one that changes the boolean object of the specified item so that the view shows the input element for the user instead of the data. However, $digest re-runs the $scope.getItemsSC(item) function because the $watches were modified, and that´s what I want to avoid, because in this case the input elements are never shown.
I thank in advance any help provided
Instead of using the HTML to call functions when data is a available, use the $promise property attached to the resources.
$scope.list = function () {
$scope.items = serviciosConceptoFactory.query();
$scope.itemsT = serviciosConceptoTipoFactory.query();
$scope.items.ServicioConceptoTipo = $scope.itemsT;
$scope.itemsS = serviciosFactory.query();
$scope.items.Servicio = $scope.itemsS;
$scope.itemsC = clientesFactory.query();
$scope.itemsS.Cliente = $scope.itemsC;
var promiseArray = [$scope.items.$promise,
$scope.itemsT.$promise,
$scope.itemsS.$promise,
$scope.itemsC.$promise
];
$q.all(promiseArray).then(function(resultsArray) {
var items = resultsArray[0];
var itemsT = resultsArray[1];
var itemsS = resultsArray[2];
var itemsC = resultsAttay[3];
//create mirror array here
//create editingData array here
});
};
By using the .then method of the promises, the processing of the data can be delayed until it arrives from the server. This way there is no need for the HTML to call functions.

Angularjs - To pass scope, from modal bootstrap window

I have the next html form (with a input field disabled for default, called unitCreator):
<div class="form-group col-xs-12 col-md-12">
<label for="unitcreator" class="control-label unit-creator">Org. Unit Creator</label>
<input type="text" class="form-control unit-creator" id="unit-creator" name="unit-creator" ng-model="unitCreator" ng-disabled="!unitCreator" />
<a data-toggle="modal" data-target="#myModal"><img src="/WebOpportunities/static/img/ico_search.png" class="search" /></a>
</div>
The icon opens a window modal, with a html table, when i click about a row, i wish input field unitCreator enabled, to pass the column value.
This is my table code html in modal bootstrap:
<div class="modal-body">
<table class="table table-hover">
<thead>
<tr>
<th>Branch</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="organizational in organizationals" ng-class="{'selected':$index == selectedRow}" ng-click="setClickedRow($index)">
<td>{{organizational.branch}}</td>
<td>{{organizational.name}}</td>
</tr>
</tbody>
</table>
</div>
This is my code js:
$scope.managers = [
{name: 'Ana Faedo Iglesias'},
{name: 'Cristina Menendez'},
{name: 'Daniel Piriz'}
];
$scope.selectedRow = null;
$scope.setClickedRow = function(index){
$scope.selectedRow = index;
}
$scope.createSelectRowClick = function(){
if ($scope.selectedRow==null)
{
alert("Any rows selected");
}
else
{
//here, i enabled the unitCreator field input and i put the column value of the table inside input field unitCreator
$scope.unitCreator = false; //this not working
//alert("hola" + $scope.selectedRow);
//alert("valuetd " + $scope.organizationals[$scope.selectedRow].name)
}
}
I base in this example to select the table row: http://code.ciphertrick.com/2014/12/06/highlight-a-selected-row-in-ng-repeat-using-ng-class/ Demo: http://code.ciphertrick.com/demo/ngClass/
The column value, i get it so (but i dont know how pass it, to modal window to unitCreator input field):
$scope.organizationals[$scope.selectedRow].name
How could do it? thanks,
Instead of passing the index, just pass the object. They you don't have to worry about deferencing from the array
<tr ng-repeat="organizational in organizationals" ng-class="{'selected':$index == selectedRow}" ng-click="setClickedRow(organizational)">
and
$scope.setClickedRow = function(organization){
$scope.selectedOrganization = organization;
}

Populate and update a table with data from a different table

My site allows for a user to search for a term which returns a table of associated songs. When the "Add Track" button in a particular row is clicked after the search, the respective track name and trackId are added to the table "playlist". The problem I am having is that once "Add Track" is clicked within a different row, the data from that row is not added to the "playlist" table, but rather it just replaces the previous information. I need to be able to generate a cumulative table. Any help would be great and thanks in advance!

}
var onSearchComplete = function(response){
$scope.data = response.data
$scope.songs = response.data.results
}
var onError = function(reason){
$scope.error = reason
}
}
I saw some issues with your code. First the code below
$scope.addedtracks = [{song:'trackName', song:'trackID'}]
$scope.addedtracks.push(song)
Acording to your html, you are passing the song object to the handleAdd. So just remove the first line from code above. After that step, declare addedtracks array before handleAdd like below
$scope.addedtracks = [];
Modify the ng-repeat for the playlist like below:
<tr ng-repeat="song in addedtracks track by $index">
<td>{{song.trackName}}</td>
<td>{{song.trackId}}</td>
</tr>
And that's it. Note that I used track by $index because ngRepeat does not allow duplicate items in arrays. For more information read Tracking and Duplicates section.
Finally this is working plunker

knockout js showing related objects(selected id) on click

I'm new to Knockout js and need some advice. What I am trying to do (the correct way) is have orders listed in a grid and a "production" button that when it is click, will show only the production objects that have matching id's to the order id. I'm trying to wrap my head around Knockouts binding, but I think I am over thinking things.
right now I have 2 objects Order and Production with are observable arrays filled with observables. Order has value of orderId and Production have value of prodId that I am checking for a match. I'm now wondering if I should not make this on object with mutli-dimensional array. Would it be easier to show selected data that way?
here is an example of the initial arrays
var initProduction = [
new Production({
proId:"183175",
pType:"Art TIme",
startTime:"11:20",
stopTime:"11:50",
totalTime:"",
by :"MJ"
})
var initData = [
new Order({
date:"06-09-2014",
orderId:"183175",
name:"Columbus Africentric",
dateRec:"05-23-2014",
rushDate:"",
totalQty:55,
parts:"1",
auto:"No",
type:"Local",
})
]
so should I combine into a multidimensional array? And if so, how would I do that? And how would I create a click event to show related data in another table showing only the production info.
I hope this makes sense and someone can help me. I apologize for my ignorance.
here is a stripped down version of my html bindings
<table>
<tbody data-bind="foreach:filteredOrders">
<tr>
<td>
<label class="read" data-bind="text:orderId, visible:true" />
</td>
<!-- controls -->
<td class="tools">
<button class="button toolButton" data-bind="click: $root.showSummary">Show Production</button>
</td>
</tr>
</tbody>
</table>
<h3>Production Summary</h3>
<table class="ko-grid" id="menu" >
<tbody data-bind="foreach:filteredProds">
<tr>
<td>
<div>
<label class="read" data-bind="text:proId, visible:true" />
</div>
</td>
</tr>
</tbody>
</table>
I would just have an orders array and then link the production object to the order.
var model = {
orders: [
{
date:"06-09-2014",
orderId:"183175",
name:"Columbus Africentric",
dateRec:"05-23-2014",
rushDate:"",
totalQty:55,
parts:"1",
auto:"No",
type:"Local",
production: {
proId:"183175",
pType:"Art TIme",
startTime:"11:20",
stopTime:"11:50",
totalTime:"",
by :"MJ"
}
},
{
date:"06-09-2014",
orderId:"183176",
name:"Angle Africentric",
dateRec:"05-23-2014",
rushDate:"",
totalQty:55,
parts:"1",
auto:"No",
type:"Local"
}
]
};
In the above json the second order doesn't have a production object.
Then in the viewModel I would use a computed which will return the orders depending on if all orders or only production orders should be shown. I've created a toggle here which is linked to the button.
var ViewModel = function (model) {
var self = this;
self.orders = $.map(model.orders, function (order) { return new Order (order); });
self.toggleProductionMode = function (order) {
order.showProductionOrder(!order.showProductionOrder());
};
};
var Order = function (order) {
var self = this;
ko.utils.extend(self, order);
self.showProductionOrder = ko.observable(false);
};
View:
<table>
<thead>
<tr>
<th>Id</th>
<th>Name</th>
</tr>
</thead>
<tbody data-bind="foreach: orders">
<tr>
<td data-bind="text: orderId"></td>
<td data-bind="text: name"></td>
<td data-bind="if: production"><button data-bind="click: $root.toggleProductionMode">Toggle Production Orders</button>
</td>
</tr>
<tr data-bind="visible: showProductionOrder, with: production">
<td colspan="3">
<table>
<tr>
<th>proId</th>
<th>pType</th>
</tr>
<tr>
<td data-bind="text:proId"></td>
<td data-bind="text:pType"></td>
</tr>
</table>
</td>

Restricting checkbox selection to a subset w/out using functions in ng-repeat

I want to restrict the number of records that may be selected in a list to a subset of the total records by disabling the remaining records once the max is reached. The list may be 1000s of records in length so performance is an issue. I'm worried my current solution (below/fiddle) will not scale. I've read several articles that warn against using functions (maxSelected() in this case) in ng-repeat for performance reasons, but not sure how I can accomplish this without them? Any suggestions would be greatly appreciated!
Here's the fiddle... http://jsfiddle.net/ALPEP/
HTML:
<div ng-controller="recordsCollectionController">
<table>
<tbody>
<tr
ng-repeat="record in records"
ng-class="{info:selected[record.id], warning:!selected[record.id] && maxSelected()}">
<td>
<input
type="checkbox"
ng-model="selected[record.id]"
ng-disabled="!selected[record.id] && maxSelected()"
id="{{record.id}}"/>
</td>
<td>
<label for="{{record.id}}">{{record.name}}</label>
</td>
</tr>
</tbody>
</table>
</div>
JS:
angular
.module('App',[])
.controller('recordsCollectionController',function($scope){
$scope.selected = {"1":true,"2":true,"3":true};
$scope.records = [
{"id":1,"name":"Homer"},
{"id":2,"name":"Marge"},
{"id":3,"name":"Bart"},
{"id":4,"name":"Lisa"},
{"id":5,"name":"Maggie"}
];
$scope.maxSelected = function(){
var count = 0;
for(x in $scope.selected){
if($scope.selected[x]) count++;
}
return (count===3) ? true : false;
};
});
Here's one option. Your original code had 2*N^2 compares per $digest. This has N compares per selection change. The basic change is to track the selected count and update it via ng-change, rather than counting it again every time it's needed.
<div ng-controller="recordsCollectionController">
<pre>selected = {{selected}}</pre>
<table class="table table-bordered table-striped">
<colgroup>
<col style="width:20px"/>
<col/>
</colgroup>
<tbody>
<tr
ng-repeat="record in records"
ng-class="{info:selected[record.id], warning:!selected[record.id] && selMax}">
<td>
<input
type="checkbox"
ng-model="selected[record.id]"
ng-disabled="!selected[record.id] && selMax"
ng-change="updateSelected()"
id="{{record.id}}"/>
</td>
<td>
<label for="{{record.id}}">
{{record.name}}
</label>
</td>
</tr>
</tbody>
</table>
</div>
angular
.module('App',[])
.controller('recordsCollectionController',function($scope){
$scope.selected = {"1":true,"2":true,"3":true};
$scope.selMax = true;
$scope.records = [
{"id":1,"name":"Homer"},
{"id":2,"name":"Marge"},
{"id":3,"name":"Bart"},
{"id":4,"name":"Lisa"},
{"id":5,"name":"Maggie"}
];
$scope.updateSelected = function(){
console.log("Ping!");
var count = 0;
for(x in $scope.selected){
if($scope.selected[x]) count++;
}
$scope.selMax = (count >= 3);
};
});
