How can we achieve product filter page using angularjs with multi selection of checkboxes?

I have created a tabular page in which i need to filter the table with filters using a left side facets boxes of different category but with multi-selection options and i need to use Angularjs for this requirement.
I need to check/uncheck using the clear filter selection .
Any helping library can help to achieve the same or we need to do some logic around the checkboxes to achieve this.
My checkbox code looks like this:
<div class="col-sm-2" style="padding-top: 10px; padding-bottom: 20px;">
<div class="facetBx sltBx" ng-show="tabFilters.length > 0">
<p class="facetBxTitle"><i class="fa fa-filter"></i> Filter Selection
<a class="clrSlt" ng-click="clearAllFilters();">Clear</a>
</p>
<div class="facetBxChld" id="uRslctn">
<ul>
<li ng-repeat="item in tabFilters">
<div class="crop">
<strong title="{{item}}">{{item}}</strong>
</div>
<i class="fa fa-remove rmvThs" style="font-size: 14px;color:#000;float: right;" ng-click="checkItem(item, item,false);"></i>
</li>
</ul>
</div>
</div>
<div class="facetBx" ng-repeat="item in filters">
<p class="facetBxTitle bomtype">{{item.label}}</p>
<div class="facetBxChld" id="bomFacet">
<ul class="multiselect" style="max-height: 140px;overflow-y: auto;">
<li ng-repeat="(k,v) in item.values">
<input type="checkbox" ng-model='isSelected' ng-click='checkItem(item.name, k, isSelected)'>
<span> {{k}} ({{v}})</span>
</li>
<li ng-show="value.length == 0">
No Data Available.
</li>
</ul>
</div>
</div>
</div>
Below website are the reference of the code which i am trying to build:
www.jabong.com
The UI(HTML) is done but i am facing the trouble in the maintaining the checking and un-checking of the checkboxes which are not clearing off.
I believe i need to code something in the ng-model of checkbox to achieve it but i am not able to be successfull so need help on the same.
Sample Plunkur for the same:

Thanks in advance.

Basically you need to keep track of ng-model of checkboxes with some property in your $scope. I did this by modifying your $scope.filters and adding selected property inside it, like below.
var filters = [{
label: 'Brand',
name: 'brand',
values: {
Blackberrys: 503,
Arrow: 175,
ParkAvenue: 358
}
}, {
label: 'Color',
name: 'color',
values: {
Black: 100,
Green: 200,
Red: 300
}
}]
function loadFilters() {
$scope.filters = filters.map(function(filter) {
var filter = angular.copy(filter);
for (var key in filter.values) {
filter.values[key] = {
selected: false,
count: filter.values[key]
}
}
return filter;
})
}
loadFilters();
Then you can call loadFilters() any time you want to clear all filters. Please see POC attached below.

You should try 'ng-change' on checkboxes to trigger a method which changes the values according to checked and unchecked checkboxes.
For Ex.
<input type="checkbox" ng-model='isSelected' ng-click='checkItem(key, k, isSelected)' ng-change="yourMethodHere()">
in JS:
$scope.yourMethodHere = function() {
if (isSelected) {
// filter the values here
} else {
// non filtered values
}
}
By doing this you do not need to even maintain the values of exiting checked/unchecked checkbox.

Need to add multiple divs with same content inside a single div on a click against the parent div

Here is my piece of code, a function to add a meal template:
vm.addMealTemplate = function() {
$scope.mealCount++;
$compile( $(document.createElement('div')).attr("id", 'mealDiv' + $scope.mealCount).addClass("mealDiv"+$scope.mealCount).after().html(
'<select ng-options="(option.name ) for option in mealOptions" ng-model="selectedOption'+ $scope.mealCount+'" />' +
'<input type="text" placeholder="Meal timings" id="time'+ $scope.mealCount +'"/>' +
'<a id="mealCount" ng-class="mealCount" ng-click="addItemCategory()" uib-tooltip="Add category" tooltip-trigger="mouseenter" tooltip-placement="bottom"><i class="fa fa-plus"></i></a>'
).appendTo("#meals")
// $("#meals").append(newMealDiv)
)($scope);
}
On clicking calling the addItemCategory() for the specific div, I want another div to get added as a child of that div. There can be mutiple meal templates, and for each template I can call the addItemCategory mutliple times, and I want the category to be added to the same div for which the function has been called. How do I achieve this?
Currently I am using mealCount variable from scope to have the context, but once it gets increased, I have no way to access the divs added previously, to add the new element to that div. Any way using jQuery or AngularJs?

You can use ng-repeat
For example:
angular.module('app', []).
controller('ctrl', function($scope) {
$scope.meals = [];
});
.meal {
border:1px solid;
padding:10px;
margin-bottom:10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<div ng-repeat="meal in meals" class="meal">
<select ng-model="meal.count">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
<input type="text" placeholder="Meal timings" ng-model="meal.timing" />
<div>
<div>Categories:</div>
<div ng-repeat="cat in meal.categories track by $index">
<input type="text" ng-model="meal.categories[$index]" />
</div>
<button ng-click="meal.categories.push('')">Add Category</button>
</div>
</div>
<button ng-click="meals.push({categories:[]})">Add meal</button>
<hr />
{{meals | json}}
</div>
Note: I changed the models etc. it's just example..

Here's an example Plunker on how your problem can be solved with ng-repeat in Angular:

<link rel="stylesheet" href="style.css">

<body ng-app="restaurant" ng-controller="meal-controller">
<div ng-repeat="meal in meals track by $index">
<select ng-options="option.name for option in mealOptions" ng-model="meal.selectedMeal"></select>
<input type="text" placeholder="Meal timings" id="{{'time'+ $index }}" ng-model="meal.timing"/>
<a id="mealCount" ng-class="mealCount" ng-click="addItemCategory()" uib-tooltip="Add category" tooltip-trigger="mouseenter" tooltip-placement="bottom"><i class="fa fa-plus"></i></a>
</div>
<button ng-click="addMeal()">Add meal</button>
</body>
</html>
-
// Script.js
angular.module('restaurant', [])
.run( ['$rootScope', function( $rootScope ) {
}]
);
angular.module('restaurant').controller('meal-controller', [ '$scope', function( $scope ) {
$scope.meals = [];
$scope.mealOptions = [{ name: "option1"}, { name: "option2"}, { name: "option3" } ];
$scope.addMeal = function() {
$scope.meals.push({ selectedMeal: null, timing: "timing" });
}
$scope.addItemCategory = function() {
}
}]);
I am not entirely sure about how you want the logic to work, but I am sure that you can modify this example to fit your needs.
Ng-repeat works like a loop which prints the content it is wrapping until the end of the array. Ng-repeat has a lot of features like tracking elements in the array by index, this can used to (like in the example) give each input an unique id.
If you need to make some specific changes to a meal, you can pass it as an argument, for example if you want to delete a specific meal you can have a button inside the ng-repeat like this:
<button ng-click="deleteMeal(meal)">Delete Meal</button>
This means that you do not have to access the meal specifically by, for example, its id with jQuery.
I would say it is not recommended to mix angular and jQuery the way you are doing now. Try to stick with Angular and avoid jQuery. In some special cases where you need to do element specific modifications it can be achieved by using jQlite:

Set variable if input field contains text

I have a search box with an icon which slides to the right if the input field is focused.
I use ng-focus and ng-blurto set the active state of the icon. If the input field contains a text, the icon should have the active state. How do you achieve this the angular way?
<div class="search">
<label for="search_users" style="background-image: url('assets/img/search_big.png')" ng-class="{ active: uFocus }"></label>
<input id="search_users" ng-model="user_query" ng-focus="uFocus=true" ng-blur="uFocus=false">
</div>

You can use expressions in ng-class for example
ng-class="{ 'active': (uFocus || user_query.length>0) }"
This will add the active class to your input in case of it is focus, or the user enter any input
You can see a working example of it:
angular.module('app',[])
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<style>
.active{
background-color:blue
}
</style>
<div ng-app="app">
<label ng-class="{active:user_query.length>0 || isfocus}">The Label</label>
<input ng-model=user_query ng-focus="isfocus=true" ng-blur="isfocus=false">
{{user_query}}
</div>

How to ng-style one element it's $index created by ng-repeat?

I have 2 directives: wa-hotspots & wa-tooltips.
On ng-mouseover of wa-hotspots it takes that $index of wa-hotspot and sets the visibility and position of wa-tooltip via ng-class:on and ng-style="tooltipCoords" by matching indexes.
Note: Since wa-hotspots & wa-tooltips share the same collection page.hotspots and therefore they share teh same index via ng-repeat
Problem:
When you hover over wa-hotspots it sets the ng-style position to ALL of the elements in wa-tooltips. I only want it ot set the proper matching index. Since the visiblity is controlled by ng-class, This doesn't really matter but it seems like it's extra overhead that could be avoid.
Therefore:
Question:
How can I make sure that my ng-style isn't styling all the wa-tooltips on hover of wa-hotspots? But rather, style only the tooltip that matches the proper shared index?
<ul id="wa-page-{{page.pageindex}}" class="wa-page-inner" ng-mouseleave="pageLeave()">
<li wa-hotspots
<map name="wa-page-hotspot-{{page.pageindex}}">
<area ng-repeat="hotspot in page.hotspots"
class="page-hotspot"
shape="{{hotspot.areashape}}"
coords="{{hotspot.coordinatetag_scaled}}"
ng-mouseover="showTooltip($index, hotspot.coordinatetag_scaled)"
ng-mouseout="hideTooltip()">
</map>
</li>
<li class="tooltip-wrapper">
<ul class="tooltip">
<li wa-tooltips
ng-repeat="hotspot in page.hotspots"
ng-class="{on: hovered.index == $index}"
ng-mouseover="hovered.active == true"
ng-mouseout="hovered.active == false"
ng-style="tooltipCoords" hotspot="hotspot">
</li>
</ul>
</li>
</ul>
tooltip:

You need to make it per item like in your case - hotspot.tooltipCoords then set that variable by index.
you can do the check inside the expression function.
Heres a fiddle
<div ng-controller="MyCtrl">
<div ng-repeat="item in items" ng-style="isChecked($index)">
name: {{item.name}}, {{item.title}}
<input type="checkbox" ng-model="item.checked" />
</div>
</div>
...
$scope.isChecked = function($index){
var color = $scope.items[$index].checked ? 'red' : 'blue';
return {color:color};
}

Instead of
ng-mouseover="hovered.active == true"
ng-mouseout="hovered.active == false"
use
ng-mouseover="hotspot.class== 'active'"
ng-mouseout="hotspot.class== ''"
and after that you can use hotspot.class in ng-class ie:
ng-class="hotspot.class"
Please see demo below:
var app = angular.module('app', []);
app.controller('homeCtrl', function($scope) {
$scope.items = [{
id: 1
}, {
id: 2
}, {
id: 3
}, {
id: 4
}]
});
.red {
background-color: yellow;
}
p {
background-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="homeCtrl">
<p ng-repeat="i in items" ng-mouseover="i.class='red'" ng-class="i.class" ng-mouseout="i.class = ''">{{i.id}}</p>
</div>
</div>

Use the below one
<div class="col-md-4 col-xs-12 col-lg-4" ng-repeat="obj in items">
<button type="button" class="btn btn-sm pull-right" ng-class="obj.class" ng-click="obj.class='test'" >
Write a new class "test". Instead of click you can use the same in ngmouseover

How to assign alternate class to rows in Angular JS?

I want to assign alternate class to rows in a table. I am using ng-repeat on
<tr ng-repeat="event in events">
I want to get output like this:
<tr class="odd">...</tr>
<tr class="event">....</tr>
I've tried this (doesn't work):
<tr ng-repeat="event in events" class="$index % 2 == 0? 'event' : 'odd'">
I can't get it to work. Also it seems like Angular is using 'class' attribute to. Why is it doing so? Can I tell AngularJS not to use the class attribute for internal evaluations?
Please help. Thanks!

You should be using the angular directives ngClassEven and ngClassOdd for this.
Have a look at the documentation section for how to use them
http://docs.angularjs.org/api/ng.directive:ngClassEven
http://docs.angularjs.org/api/ng.directive:ngClassOdd

From the Angular docs..
Use ng-class-odd ng-class-even
<li ng-repeat="name in names">
<span ng-class-odd="'odd'" ng-class-even="'even'">
{{name}}
</span>
</li>

As #ganaraj states ng-class-odd and ng-class-even are the right way to do this, but for the benefit of searchers, your initial proposal wasn't far off working in Angular >=1.2.19.
Here is a closely related example of something that would have worked and would also work if coloring more than alternate rows (e.g. every 3 rows):
<div>
<style>
.color0 {
background-color: lightblue;
}
.color1 {
background-color: lightyellow;
}
.color2 {
background-color: lightgray;
}
</style>
<div ng-repeat="result in results" ng-class="'color' + ($index % 3)">
<div>
<p>{{result.myText}}</p>
</div>
</div>

You can also use the ng-class-odd and ng-class-even directives directly within the ng-repeat directive.
<div class="cssOneProductRecord"
ng-repeat='..'
ng-class-odd="'cssProductOdd'"
ng-class-even="'cssProductEven'" >
Which gives us nice alternating classes for each row:
