Is a directive necessary for a search element in this component?

Question

Is a directive necessary for a search element in this component?

I am currently learning angularJS and although it would be simpler to use JQuery for this task, I am determined to do it the right way.

Essentially, I want to create a text input field where users can type in a search term, press a search button, and then use Ajax to search for and display the results in a list.

I believe I need to utilize directives to achieve this, is that correct?

I am not asking for someone to do this for me, but rather to provide some guidance or examples so I can create it myself.

MY DIRECTIVE (IN PROGRESS)

app.directive('recordSearch', function() {
return {
    restrict: 'E',
    scope: {
        searchInfo: '=info'
    },
    templateUrl: 'partials/record-search.html',
    link: function(scope, element, attr) {

    }
};
});

RECORD-SEARCH.HTML

<label class="item item-input">
<span class="input-label">{{ searchInfo.title }}</span>
<i class="icon ion-search placeholder-icon"></i>
<input type="search">
</label>

ON MY ACTUAL PAGE

<record-search info="company"></record-search>

Considering your intention to recycle the element, opting for a directive seems like the right choice.

From the information you provided, it seems the structure could be arranged as follows:

directive('mySearch', function(Item){
  return {
    restrict: 'E',
    // To display results outside of the directive, a two-way binding variable is needed
    scope: {},
    link: function(scope, elem, attrs) {
      scope.search = function(query){
        Item.search(query).then(function(results){
          scope.results = results.data;
        });
      };
    },
    // The template includes a search button and potentially ng-repeat for results, depending on your display preference
    templateUrl: 'my-template.html' 
  }
})
.factory('Item', function($http){  
  var item = {};

  // This factory manages general item data, including searches
  item.search = function(query){
    // Execute AJAX search using $http
  };

  return item;
})

... Your specific goals may lead to different outcomes. In most cases, besides using directives for reusable components, utilizing services for data management (such as AJAX queries) is advisable.

Here is a suggested method:

1- Instead of using a directive for the ajax call, it is recommended to utilize $http or $resource module in your controller or a separate factory. Then, simply include an ng-click directive in your input tag to invoke your search function and provide the search data.

2- When displaying the data, you have the option to use a directive or not. All you need to do is assign the incoming data to the appropriate scope, for example, $scope.data = factoryService.data; or something similar.

No custom directive is required for this task. Simply place your searchInfo binding inside the input element and utilize the built-in ng-click directive. An excellent example of this technique can be seen at .
