Combining angularJS and bootstrap to dynamically load pop-up prompt content_AngularJS

angularjs is an excellent web front-end framework developed by the Google team. With so many web frameworks currently available, angularjs can stand out from the rest in terms of architectural design, two-way data binding, dependency injection, directives, MVC, and templates. Angular.js innovatively integrates back-end technology into front-end development, sweeping away jQuery’s former glory. Using angularjs is like writing backend code, more standardized, more structured, and more controllable.

1.bootstrp pop-up prompt

Bootstrap has helped us encapsulate the very useful pop-up prompt Popover.

2. Custom popover command

We use a command to add a popover to any element, and the popover content can be changed according to the situation.

JS:

<script>
  var app = angular.module('testApp', []);
  app.factory('dataService',function() {
    var service = {};
    service.cacheObj = {};
    service.getAppName = function (appId, callback) {
      if (service.cacheObj[appId]) {
        console.log('get name from cache');
        callback(service.cacheObj[appId]);
        return;
      }
      //here is sample. Always ajax.
      service.cacheObj[appId] = 'QQ';
      callback('QQ');
    };
    return service;
  });
  app.directive('myPopover', function (dataService) {
    return {
      restrict: 'AE',
      link: function (scope, ele, attrs) {
        $(ele).data('title','App');
        $(ele).data('content', "<div id ='popDiv'>Name:-</div>");
        $(ele).popover({ html: true, trigger: 'hover'});
        $(ele).on('shown.bs.popover',function() {
          var popDiv = $('#popDiv');
          console.log(popDiv);
          dataService.getAppName('xxx',function(name) {
            popDiv.html('Name:'+name);
          });
        });
      }
  };
  });
  app.controller("test",function($scope) {
  });
</script>

html:

<div ng-app="testApp">
<div ng-controller="test">
<div>
<a my-popover>app 1</a>
<a my-popover>app 2</a>
</div>
</div>
</div>

The above is the combination of angularJS and bootstrap introduced by the editor to dynamically load pop-up prompt content. I hope you like it.
