displaying results using angular js + php, how to show loader image until data is loaded, here my code is written below,
How do I have AngularJS show a loading image until the data has finished loading?
app.js file
var app = angular.module('myApp3', ['ui.bootstrap']);
app.filter('startFrom', function() {
return function(input, start) {
if(input) {
start = +start; //parse to int
return input.slice(start);
}
return [];
}
});
app.controller('customersCrtl', function ($scope, $http, $timeout) {
$http.get('http://www.testurl.com/index.php/site/getprofileLocations').success(function(data){
$scope.list = data;
$scope.currentPage = 1; //current page
$scope.entryLimit = 20; //max no of items to display in a page
$scope.filteredItems = $scope.list.length; //Initially for no filter
$scope.totalItems = $scope.list.length;
});
$scope.setPage = function(pageNo) {
$scope.currentPage = pageNo;
};
$scope.filter = function() {
$timeout(function() {
$scope.filteredItems = $scope.filtered.length;
}, 10);
};
$scope.sort_by = function(predicate) {
$scope.predicate = predicate;
$scope.reverse = !$scope.reverse;
};
});
and php code is here
<html ng-app="myApp3" ng-app lang="en">
<div ng-controller="customersCrtl">

display loader onload and hide it once data loaded.
$scope.showLoader = true;
$http.get('http://www.testurl.com/index.php/site/getprofileLocations').success(function(data){
$scope.showLoader = false;
// rest of your code
});
EDIT: html code from Saeed's answer
<div ng-show="showLoader"><!-- so this div containing img will be dislpayed only when the showLoader is equal to true-->
<img src="source"> <!-- or any other spinner -->
</div>
Addition to @Venugopal`s answer. To display that loading image in the html
<div ng-show="showLoader"><!-- so this div containing img will be dislpayed only when the showLoader is equal to true-->
<img src="source"> <!-- or any other spinner -->
</div>
