Progress bar for Angularjs application by using directives is simple and real easy. I was googling and could not found any directive way, if you will check most of the people says before call the http method open the progress bas and close once you get the result or get any error. Do you think it is good way to write the code in every http request, I don't like it. What ever we are going to create will work with synchronous http request as well as asynchronous request.
Let's see some suggestions from different web sites, hope it will not disturbed you :)
<div id="mydiv">
<img src="lib/jQuery/images/ajax-loader.gif" class="ajax-loader"/>
</div>
// JavaScript to show and hide
$('#mydiv').show();
$('#mydiv').hide();

Do you want to use the above code your application, hope No. So let's create our simple directive in our app.js file
var app = angular.module('MyApp', ['ui.router', 'ui.bootstrap']);
app.config([..... funtion(....){
...............
...............
}]);
app.directive('loading', ['$http', function ($http) {
return {
restrict: 'A',
link: function (scope, elm, attrs) {
scope.isLoading = function () {
return $http.pendingRequests.length > 0;
};
scope.$watch(scope.isLoading, function (v) {
if (v) {
elm.show();
} else {
elm.hide();
}
});
}
};
}]);
Interesting part is the html, we only want one div that's it, If you are thinking where is the progress image, then control your horses, we will add that inside the CSS class, here is the complete HTML
<div class="loading-dialog" data-loading>
</div>
Put this code somewhere on you index.html page, now see the loaging-data class
.loading-dialog {
display: none;
position: fixed;
z-index: 1000;
top: 0;
left: 0;
height: 100%;
width: 100%;
background: rgba( 0, 0, 0, .2 ) url('../images/loading.gif') 50% 50% no-repeat;
}
What this class will do:
This is only the code you need to play the wait progress. If you note I am adding image from CSS by using the backgound: url('../images/loading.gif') and positioning the image to the center of the page. so you need a an image to play, if your image folder is not on the root folder then you can change the URL path accordingly.
